Title: Engine mounting failed - advise please? (UPDATE)
Post by: barlimow on May 29, 2011, 08:03:37 pm
Hi all (couldn't remember my log-in, as been ages since I've been on, so re-registered...)

My wife was driving the car today when it made a loud bang. AA man out, and the left engine mount (as you look at the car from the front) had failed, and so the left hand side of the engine had dropped  

God only knows what knock-on damage that has caused.   We had to recover the car somewhere (obviously couldn't drive it) so it is currently dumped outside the VW garage.

Has anyone heard of an engine mount failing on a mk5 Golf (07 reg)? Surely this can't be a common occurence? Luckily she was doing about 20 mph at the time, not 70+ on the motorway.

Any helpful advice on next steps much appreciated... 2 relevant points:

1. The cambelt was changed 6 weeks ago. Even with my limited knowledge of engines I know this is a big job, and potentially an "engine out"-type scenario. I'm not looking to blame anyone here (unless justified), but will they need to adjust/remove etc the engine mounts during a cambelt service?

2. (I think this is highly irrelevant, but...) about a month ago, someone reversed into the car in a car park, leaving a fraction of paint on our front bumper, and cracking the numberplate. No damage to the bumper or anything. Surely this can't cause anything like this??

I need to talk to the garage in the morning even if it's just to push my car into the compound off the road) so any info I can be armed with would be useful, as otherwise I could potentially be looking at getting shafted for a rather large (new engine?) bill? Many thanks.

(sorry if you read this on another forum as well)

I may be wrong , but im sure one of the engine mounts are removed to help in access fitting the cambelt?

Someone may know more, but could be wrong?

Yup, removing the engine mount (i.e.the one that's failed) makes changing the cam belt a little easier by giving more access room.

I thought that mount has to be removed for cambelt change

That mount has to be removed to change the cambelt.  I would go back to the garage that did the work and complain.  My thoughts would be that they did not torque the bolts up the specified setting and this has allowed play in the mount and I bet the bolts have snapped.

Yea you def have to remove engine mount to access the cambelt area, this happened to my MK4 Golf too after a cambelt replacement, sounds like who ever removed the engine mount hasnt torqued the bolts correctly that hold the engine mount that attaches to the engine block just as "560ctyvrs" says
Title: Re: Engine mounting failed - advise please?
Post by: gazbutS3 on May 29, 2011, 10:53:47 pm
I'm pretty sure that VW specify using new bolts as well
Title: Re: Engine mounting failed - advise please?
Post by: vRStu on May 29, 2011, 11:47:28 pm
Yep new bolts should be used when fitting a cambelt.

Who fitted the belt?
Title: Re: Engine mounting failed - advise please?
Post by: QD MBE on May 30, 2011, 01:39:14 am
The bolts that hold the engine mount on are stretch bolts.  So are designed for one use only.  They will fail if re-used, and cause damage.  I hope they have not caused damage to the head/block due to being loose.

When you get up there too I would have a look to see if bolts have come loose.

Also on my last post, I think reusing once is ok but not sure I would do it twice!

How many miles has yours done and how many cambelt changes?

Post by: h4rdy on May 30, 2011, 08:05:32 am
It would take a lot to snap all of them I would say left loose.

Also when the THS ones turned up they only supply one bolt and thats the lower mount.

Thanks all for the replies. It was a VW main dealer (I probably shouldn't name them). 1st cambelt change, 35k miles.

Looks like undoubtedly it will be cambelt-change related  then. But sounds like they will say they didn't need to change the bolts, and it was just "unlucky" that this one failed, and I am on my own... though I will have to argue that they can't have been torque'd properly etc...

I'm guessing they won't be open today though.

Just says "repair kit 06F198119A" which I read on another thread doesn't include bolts (pic below).

If they say "you don't need new bolts", how can I definitely prove that they SHOULD have used them, and therefore have them "bang to rights" as you say?

Many thanks for everyone's help.

QD .. You don't even know whether the VW tech tightened them in the 1st place, so whether they were reused would mean they have indeed sheared off, or were just sat in the castings on the Engine mount ..

Only the O.P and tech at vw will see whats happened... i still think they wernt tighten and forgot about personally. But like you , only asuming as to whats happened...

They are a fair size bolt, they wont break under such a small ammount of torque. Its more like "good practice" to replace them.

Always makes you wonder why wheel bolts aernt replaced everytime a wheel or tyre is changed?

New bolts may well have Loctight on the threads to prevent them from rattling free, rather then a bolt breaking..

I wasn't invoiced for them. "Cause for concern" as in I'm stuffed then?! Or cause for concern in the quality of the work, and therefore it's their fault?
Title: Re: Engine mounting failed - advise please?

Cause for concern as in the official repair manual suggests to replace the bolts, if yours weren't then they probably should have been.
Title: Re: Engine mounting failed - advise please? (UPDATE)
Post by: barlimow on May 31, 2011, 09:18:29 am
OK, just spoke to the service manager. He said categorically that they do not need to remove the engine mounting bolts during a cambelt change, as they can access the cambelt without doing this.

In case I had misunderstood, I confirmed this again at the end of the conversation, and again he repeated that they definitely do not remove them.

This seems to be contrary to what everyone else has said though.

He's going to get back to me when they have looked at the car.

Not sure where to go with this now. Whatever he now comes back with re the damage (and it could be huge), he's going to say it's absolutely nothing to do with the cambelt change.

Post by: vRStu on May 31, 2011, 09:26:52 am
I don't have access to my workshop data at the moment but I can certainly check for you to see if removing the engine mount is the approved method, I'm pretty sure it's the generally accepted one.  If  they have someone that can do it without then I'd say he has the hands of a child.

In the interim I'd phone another dealer or two and ask if they need to remove the engine mount to access the belt.  No need to go into too much detail with them.

Are you able to get back to the car and inspect it before they do??
Title: Re: Engine mounting failed - advise please? (UPDATE)
Post by: Deako on May 31, 2011, 09:27:04 am
I can get the official cambelt change procedure for you if you like? Or if someone else has access to the VW tech processes they could post them.

It might take me a day or two to get them off a friend that works at VW.

Would be useful if you could check, many thanks.

No, I can't get back to it I'm afraid. I work nowhere near the garage.

That would be very useful, thanks Deako.

UPDATE2:

They do change the bolts. No damage to the block apparantly. They will fit new mounts, cambelt kit (precautionary). Currently undergoing compression tests (??) to ascertain everything OK. They are picking up the tab.

So far so good.

Thanks everyone for your helpful input, certainly made me feel more informed when I spoke to the dealership today.

Though he didn't say those words, that was the essense of what he said (that they were either faulty, or not secured properly, but they were now so damaged they couldn't tell).

Too right! Big relief. Though (being the way I am) I may now have a nagging doubt that it HAS done some more damage that just hasn't come to light yet...

Interesting that the service manager was so adamant that the bolts weren't loosened/removed when you first spoke to him. So is he:

1. trying to cover up?
2. ignorant of workshop proceedures?

Either way I'd think twice about patronising him again. Good job you stuck to your guns on this one. I feel that without forum input, it's likely that they would have wriggled out of any blame at all.

Great to hear it's getting sorted though. Must be a huge relief for you :happy2:

This might total rubbish, but I remember reading (somewhere on the Internet) cambelt changes on
the early AXX engine were difficult, this was made better on the later BWA engines.

What engine do you have?

Edit, I see you have an 07, so have the later BWA engine.

I know, I did wonder why he said that. Said he subsequently spoke to the Master Tech and was told differently.

Well, I think that you should ask to have a little one to one chat with the service manager & explain to him that you are going to have a serious confidence issue with him & his staff. Planting this seed in his mind should ensure that you get someone who's paranoid about the state of any work done. Worked for me a long time ago...

Given the consequences of this error, I think that you would be within your rights to ask the dealer to refund your service plan, invoice you for any work they carried out, and you'll be free. However I'd use this incident to your advantage by explaining how thin the ice under the service staff is. That way you should be good as they'll break into a sweat when they see you arrive for your next service.... :evilgrin:

Is the service plan with VW? in which case you can go to any dealer.

That said, it maybe in your interest to use that dealer for the next service, just in case you have any associated problems that develop down the line

Not sure how to play it to be honest re future servicing - my confidence is knocked in them (but dealing with it well now, albeit after the event), but at the same time I think it would be useful to use them again, as they can sort out any other problems that are consequential (god forbid) next time. And they owe me good service!

Plan isn't with VW, it's with the dealership chain. (all they "owe" me now on it is an MoT and a minor service... what can possibly go wrong?.... :grin:)

So has he actually said what went wrong? or what failed? and why has he replaced everything required F.O.C if he says he's going too? but not admitting liability.. :confused:

At least then it might give you peace of mind if it was Product failure or like we thought VW Tech error.

Great result though..

He said that 2 bolts had sheared off (sheared was his phrase). And that the state of them was such that they could not determine whether they were faulty or just not secured properly. So it's either a product fault (warranty) or tech error (dealer fault), so they need to sort regardless.

I will try to get to the bottom of it when we next speak, but don't think I'll get a lot more than that. They're not NOT admitting liability, he just hasn't said the words "it's our fault".

Overall much happier than I was last night though  :smiley:

I will try to get to the bottom of it when we next speak, but don't think I'll get a lot more than that. They're not NOT admitting liability, he just hasn't said the words "it's our fault".

Overall much happier than I was last night though  :smiley:

I am assuming all is sorted now?  Did they ever say why the bolts sheared?

Sighing.........

He has not said Steve.  Terms like 'I will try to get to the bottom of it', to me means that he had not been given full explanation at that time.  At the time of his post above I believe his car was still in VW getting sorted, which I assume he would have collected by now,  and had a face to face with the Service manager.  

The info would be useful to know, as a lot of the MK5's are now coming up to Cambelt changes at 80K, or indeed at 4 years - especially the Ed30's, so as much info on this occurrence is useful to the forum.

So call me old fashioned he has not said, I would like to find out why, just so the forum can benefit.

also if failure mode was shear, and not them being loose, then it backs up VW's instruction to Renew after use.

Glad you got this sorted :happy2:

My bet is that the bolts werent torqued down rather than faulty bolts.  Either way I am impressed that they are fitting a new cambelt free of charge, which didnt really need doing as that hadnt failed. They are fitting a new engine mount and doing checks on the engine to make sure that there is nothing else a foot.  Id be quite happy at that as they have gone above and beyond what they actually needed to do to rectify the problem.  I wouldnt worry about the minor service as they only really change the oil and perhaps the air filter if needed, so not mich can go wrong with that.  They have realised the mistake is theirs and not many dealers would be quite so customer friendly and most would shy away and say it wasnt their fault.  Good result all round :smiley:

Sorry folks, been away this weekend...update is...

Car is back  :happy2:  And feels good as new (but maybe that's in comparison to driving a Passat 2.0 diesel!).

Anyway, they dropped a courtesy car (the Passat) at my house on the Monday, and during the week fitted new mounts (both sides, at my request), new cambelt, offside cambelt cover (apparantly), did whatever they do (compression tests etc) to confirm all working OK, and delivered back to me on Thursday.

No, I never did get a "better" answer than "the bolts sheared off", as they said they were too damaged to determine the cause (they said they could have been faulty, or not secured properly). I wasn't there when they looked at it (I had to drop the car off on the Bank Hol weekend, and then I was 20 miles away at work on the first working day afterwards (Tues)), so couldn't examine them myself, and they dropped the car back for me as well.

The service manager said he will send me a photocopy of the internal recharge invoice (not sure to whom?) that details what was changed etc, and presumably (?) will say why they had to incur said cost. I will chase if I don't get this.

So overall, of course I'm not happy that it happened (obviously). But I do think they dealt with it well (so they should, some might say), and can't fault them for doing the work with no quibble, keeping me informed, getting me a courtesy car etc. And they also did a small amount (£30 worth) of additional work that was totally unrelated and didn't charge me.

Glad you got it sorted.  Make sure you get the receipt, just to prove what was done and when just in case it gives trouble again.

IMO I reckon they sheared due to be re-used, when used first time they permanently elongate, 2nd time they elongate more and fail.

There is a reason why VW say don't re-use.  As I say Just my opinion, loose bolts drop out.

I would agree Dave.

A new bolt is unlikely to fail, but both to fail is probably unheard of.

As said great result..

Still think your dealers admitting full liabilty, by more or less cover the costs.. Lose bolts will shear under high torque if not tight...

On the question about bolts falling out, I thought the bolt heads are upwards.. just an observation if there were just to "fall out"?

I havent looked on my own car but the diagrapm shows otherwise?

I am not sure it was those bolts that went.  Bolts 'C' in diagram above, Bolt into a alloy mount that is bolted by 3or 4 bolts IIRC.  

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fwww.quickerbuy.com%2Fassets%2Fphoto%2Favatar%2F294981%2Fbig_2000-vw-golf-gls-passenger-side-engine-mount-bracket.jpg&hash=028bae0567a0ea309b203c4adcf007c91f47bdda)

The 2 holes that you can see bottom Right are the threaded holes that bolts C torque into.

The 'U shaped Gap' created by the 2 spigots is the slot that the cam belt runs through  (these spigots actually fit into holes in the cam belt cover - hence to even get the plastic cover off you have to remove the mount and the bracket), hence the need to remove the mount and this bracket when changing the cam belt.  this bracket is from a Mk4, but the principle is much the same on a MK5 IIRC.

I think it is these bolts that failed and sheared (Having seen it before over on the MK4 forum), and hence the engine dropped.

Eg this chap who had his cambelt changed 2300 miles before his bolts sheared.  He also had the unfortunate problem of the AA cracking his sump as they dragged it into the low loader.

Ray (aRd Some may know him)

those bolts you mentioned need to be changed each time a cam belt is done, most garage don't change them.   I think they're stretch bolts.   I hope it all works out for you.

Also another poster.

yes mate they are stretch bolts and need to be changed every time cambelt is done. i also found that out the hard way 5 months after purchasing car.


As I say just my considered opinion.  But very glad you are sorted.

Theres a misconception about stretch bolts, there are stretch bolts which are aneeled (heat process) this makes them crunchy on the outside (to help roll the threads) and squidgy on the inside, theyre about 15 quid each and have special markings on them, they also stretch prior to ultimate load. Normally found in aerospace applications and connecting rods.

VW Bolts which are referred to as stretch bolts are a lower class of tensile strength which are in essence over torqued one time only, many of the suspension and subframe bolts are stretch bolts which are 8.9 class but normally get 12.9 torque settings plus a quarter turn, cheap and wont come loose - just dont reuse them

oops my cars gonna fall apart, the subframes been off and the bolts re-used and the engine mounts too  :laugh:

so when someome fits a walk kit do they fit new bolts?

Post by: vRStu on June 06, 2011, 07:11:27 am
Gaz you'd probably be quite horrified if you realised how many of the VW bolts are 'once only'.

In answer to your question IIRC then yes they should be replaced.

Not going to be taking photos of your car when you are next flying round Anglesey. More risky than traveling behind JoesGTI.  :laugh:

Hey dude. Haven't been on here for a while but caught this thread. Exactly the same issues I had. Dealer admited they hadn't changed the bolts after I said it was in the workshop manual (thanks Stu!)

Glad you got your money back. :happy2:
