Poorly GTI atm, a few questions if anyone would be kind enough to take a look :)
VCDS Scan:
Fuel Pressure Regulator Valve (N276): Open Circuit
Visual Inspection:
Cracked Sensor on top of HPFP
Questions:
> Is this sensor replaceable? Or does it require a new HPFP?
> Even though my GTI is a 55 plate it doesn't have the Banjo's
I've replaced the Cam Follower before now, but never completely removed the fuel pump, anything to note?
:happy2:

You can buy a little shield that bolts over the top to protect it. Think @r5gtt and @Shoduchi have them.
AFAIK you the sensor itself can be changed rather than the whole pump. I'd hope so anyway - I wouldn't want to buy a whole new Loba if it happened to mine!

Have you seen the 300 odd post thread on the facebook group about those sensor cover plates? :grin:
If you haven't.....basically, Niki Gower posted a thread about the pump bolts stripping the threads out of the chain cover if using the sensor guards with OEM bolts and it all hit the fan.
I don't get it personally. I've had the engine cover off dozens of times and never once even come close to contacting the sensor with it.

That sounds bloody catastrophic! I'm always very careful doing anything under there, but there's always that worry.
Cheers for flagging that up though - I didn't realise the cover/shields were a no-no. I'll stick to my current setup!

Oh yeah, I think we've gone over that in the past. I don't blame you for not being on FB!
It's not an issue if you use longer bolts to compensate for the sensor plate thickness, but in this case the R tech customer didn't. The bolts stripped out after mapping and it all got very heated and abusive!
Post by: r5gtt on June 26, 2017, 05:39:30 pm
There's no way the new pressure of the pump after the map will pull those titanium bolts out!, even if let's say for example 4-5 threads were holding the hpfp into the chain cover where it sits as it's still catching them inside the case as I always finger tight first with pump pushed in all the way. I personally believe the pump wasn't fully home as it's spring loaded and the titanium bolts at the top were just catching the threads as it was tightened into the case and then stripped the alloy thread causing this!.
Rant over :signLOL:

Here are the bolts given by Niki at r tech to get me out of trouble where you can see one is already damaged before it's even been put in so obviously this will further damaged the threads of the chain cover where the pump fits :doh:
Why is it that garages always pin the blame on the customer I don't know :sad1:
Ps I didn't even blame anyone at the time when Niki started screaming swear words down the phone so this really upset me more than anything :sick:

I'm using the Celtemp cover and since the bolts that came with the cover were the same length of the OEM bolts, I just kept the OEM bolts. Been running fine since last November. :confused:I used the titanium bolts given to me by someone and also two washers on the top of the pump and cannot see how this would of stripped the alloy unless fitted incorrectly :confused: also some will laugh but those people are a classic example of immature twats imho as they couldn't get anymore freebees off me :signLOL: :happy2:
Post by: pudding on June 27, 2017, 10:21:50 am
The thing with pressure....think of it as resistance. Oil pumps, turbos, fuel pumps, meth pumps etc...... none of them create pressure. They create flow. Pressure is the resistance to flow, and it's that 'resistance' which brings Newton's third law into the equation, which is: "For every action, there is an equal and opposite reaction". So when Niki commands and extra 55 bar of pressure from the pump (that's 800psi of additional resistance!!), that is a LOT of additional force on the bolts.
Also remember that VW designed the pump mounting hardware to sustain 110 bar, max. When you push things beyond their design brief, you're on borrowed time.
What I don't agree with, if it's true, is how you were treated as a customer. I don't know the guy, but he has a good reputation and I can't imagine him swearing at you down the phone unless he was provoked? Professional suicide!
Anyway, get yourself a new chain cover and move on mate. Bin that silly sensor cover, I hate those stupid, ugly, pointless things :happy2:
Post by: Dan_FR on June 27, 2017, 11:16:34 am
As for the way you were treated - given the support and offer of help & repair you were offered - not a fair account at all.
As I have already said - chalk it up to experience - that your chosen bolts are not suitable for that application - and move on.

Post by: r5gtt on June 27, 2017, 12:48:49 pm
I'm afraid I agree with Niki mate. 4-5 threads is not sufficient, and titanium being way harder than aluminium, they will just pull right out. Were the threads in the chain cover in good shape before you took it to R Tech? Do you suspect they over tightened them and they then pulled out under the load or something? These things are always your word against their's unfortunately.why would they pull right out if the when they were secured by myself and I'm confident in doing so?.

Imho there is nothing wrong with fitting titanium bolts into aluminium as long as you hand tighten them up making sure you don't cross thread as same with oem bolts, you can still strip the thread either way!.
The threads were perfectly fine before this happened as I always push the pump home then hand tighten before using a spanner and as you will all know I had issue with lag or boost a while back so had to remove the pump a couple of times to trial and error and finally found the used pump being the cause so swapped the VIS internals over to my original pump and power was back up again.
I also understand the physics of it all but imo there was nothing wrong with the way I fitted this on BUT let's leave it there as I don't want it to escalate as Niki mapped the car to an awesome spec and don't wish for any name calling or pointing fingers anymore.
Also, No I didn't provoke him as all I said over the phone was the threads are stripped and two bolts have popped out and in he's own words he said on Facebook were "I spat my dummy out" which he certainly did and that was more upsetting than what happened to my car :sad1: as to me it was an easy fix and not a knackered cam!! Vis internals :scared: it was Niki who posted up on Facebook and people making judgements and comments about the owner aka me.
Oh yeah I ent getting rid of the plate as it gives definition to the engine when the bonnet is open :P
Post by: r5gtt on June 27, 2017, 12:59:08 pm
Mux lets not drag this up again.... The Titanium bolts fit perfectly without any cover or washer..... With a cover the available thread is marginal/on the limit.... Add a washer and its not. Its that simple - all R-Tech did is Torque to spec - i.e. the what is needed to safely hold the HPFP to the casing.

Sorry screaming down the phone at me is offering to resolve this??? No thanks to that's mate. Once someone over steps the line or twlks to me disrespectfully!! That's it will never even let them touch my car and on FACT I don't ever let anyone touch my car but this was one of those times I had no choice or go home fuel wasted and having to book at a very later date.
I know Niki gower knocked off a full £100+ vat for me for the map and dsg and I really appreciated that like ecstatic over the moon as no other tuner would do that for anyone they don't even know but treating a customer that way is totally uncalled for and getting people to sl** me off on fb was even worse! :sad1:
Maybe because I helped a member of this forum when his car went belly up due to another garages ways led to this but I'm no psychic.

Because thread count governs grip. Your bolts had a third of the standard grip and couldn't hold back the strain of +55 bar, the end.
If you wound your head bolts out to 4 or 5 threads into the block, do you think the cylinder head would stay put if you doubled the boost pressure?
It's a complete sh*tter for you mate, but your situation is a text book case of what happens when a bolt doesn't have enough grip. It rips out.

For anyone confused by this seemingly random and irrelevant post - R5 was one of the first to get VIS internals. I never slated the parts, simply stated there was more risk buying unknown parts from a relatively unknown seller then there was one when buying a tried and tested pump such as Auotech, LOBA or APR. But it appears R5 took this as a slight against him - god knows why. Months later (after trialling and testing with VIS internals) it appears they were indeed up to scratch and performing well. With this in mind, I decided to risk it and buy the internals. I needed some help on the intallation so messaged mux for help - he was very helpfull.
This is what R5 deems to be relevant to todays discussion.

I'm afraid you fell foul of a rather fragile design! Soft alloy casing + M6 bolts + 4-5 threads + massively increased pump resistance = cheesed out threads I'm afraid. Anyway, we live and learn. I think the point has been labored enough, but it's all good info for others I guess.

There's one on the Bay for £168 delivered brand new just an M revision instead of H.
Mine: 06F 127 025 H
Latest ?: 06F 127 025 M (http://www.ebay.co.uk/itm/GENUINE-AUDI-2-0T-PETROL-FSI-HIGH-PRESSURE-FUEL-PUMP-06F127025M-/321974277440?epid=1141404873&hash=item4af7299540:g:EYwAAOSw42JZH0ox)

One of the pins had bent, so straightened it, tested connector with meter, both sides fine... bit of plastic weld, stuck it back on, and crossed fingers...
Started rough, then evened out, EPC light disappeared; took for the usual spin and didn't come back.
Think I'll still be looking at replacing it, as I don't want to be driving quick and then it cut power like the TB has died.
Anyway, temp fix gets me rolling :)
Thanks for the replies, still looking for a standard HPFP if anyone has one knocking about :)

ive learnt yet another important lesson to NEVER EVER let anyone touch my baby again :sick:i don't know pal, spoke to an engineer of 40yrs earlier on and he seems to think the bolts would have held up fine as long as they weren't crossed into the casing :sad1: never mind though as I'll never let a soul touch my car again unless it's for tyre swaps as I forever state I don't like anyone touching my cars!!! :sick:still baffles me that even if torqued up they shouldn't have stripped as that's what happened before the pump bolts pulled out :thinking:
Because thread count governs grip. Your bolts had a third of the standard grip and couldn't hold back the strain of +55 bar, the end.
If you wound your head bolts out to 4 or 5 threads into the block, do you think the cylinder head would stay put if you doubled the boost pressure?
It's a complete sh*tter for you mate, but your situation is a text book case of what happens when a bolt doesn't have enough grip. It rips out.
I'm afraid you fell foul of a rather fragile design! Soft alloy casing + M6 bolts + 4-5 threads + massively increased pump resistance = cheesed out threads I'm afraid. Anyway, we live and learn. I think the point has been labored enough, but it's all good info for others I guess.
Just don't fit junk parts onto your car. :wink:

I bent and cracked my one when closing the bonnet one night in the dark and didn't realise the mechanics hadn't put the engine cover on properly (just placed it on top). I used high strength Araldite glue and let it set held overnight in a vice and it's been fine for over a year.
@r5gtt (http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=11199) Have you got your stripped threads sorted out yet?
There is a special recoil insert for soft metals. There's enough metal around to put them in and afterwards it will actually be stronger than original. They aren't helicoils. I'll see if I can find a photo.

The one I used went from M10 stripped, drilled out to 12.8mm and then tapped to M14 x 1.25. The insert screws in by hand until flush and then use a pin punch and hammer to hammer down the pins. This prevents it from turning.

Thank you for your help and I really appreciate it mate. I've already heli coiled the two damaged thread that evening but looking for a cheap cover as I don't like them being coiled me being me want it how it was before the damage :sad1:
Again thank you for your time in finding these :smiley:
