I did two hour trips today and the gauge didn't go above 70 once :scared: it was closer to 50 for the majority and did actually drop to 50 at some points... It only rose if I drove aggressively for a bit. What are the effects of the temp being this low?
Anyone had this and know the fix
-
Try testing it with some diagnostic tools like VAG-COM, in most cases the sensor fail or thermostat fail are common. I guess in your case is the same. If the thermostat isn't working then the fan maybe is cooling all the time. Same with the sensor if it is giving a high temperature the fan maybe is constantly working and cooling the engine. I suggest you to try to diagnose with software. Also sensor and thermostat are pretty cheep to buy :)

This is worth a read http://www.mk5golfgti.co.uk/forum/index.php/topic,78341.0.html
MPG will be low so it will hit the pocket in this weather.

Hi, looks like I'll be replacing the same as mine does what peskyjones car is doing.

Im going to try replacing just the sensors first I think
Il let you know how I get on

Yes worth doing research but most have had to do the thermostat or stats.
-
I'm going for the stats as the tt had the same issue and I should have realised this first.

Give yourself plenty time and you'll find it's no more difficult than any other job.

So bearing in mind im still learning about engines as a whole (ive only changed dv, pvc, cam follower and a cv joint gaitor, and I didnt exactly do.those with ease) it could be any of these three, stats, thermo stat or sesnors?
My temps were fine yesterday, it literally happened today which made me think sensors

Thank you very much doylebros, I'm just curious as to how many stats the 55 reg dsg has as I'm reading 3? :surprised:
Stupid golf and the second one I've ever owned, the first was a mk1 X reg 1.6 gti :jumping:

The cheaper option is well worth a try after seeing how NOT easy it is to replace the stats :rolleye:
Did I forget to mention why not check the CTS coolant temp sensor with a multimeter and see what ohms it's kicking out before replacing it?.

As with any job don't just jump in do the research,which by asking questions you,re doing.
On the above jobs well done you saved yourself time and money.However,if your going to do the main thermostat it requires time and not a job for out in the cold as it's easy for it to turn into a ball ache but no harder than a CV. Bootie just few more bits to take off.

I.found how to replace the sensors in another thread which looks reasonably simple. Ill try this tomorrow. If it doesnt work then ill research into replacing the stats.
In your very first reply doylebros the how to on replacing the three stats doesnt look TOO complicated, just time consuming. Thanks for all your help, much apreciated.

YouTube has a video of the job on a A3 which is worth a watch for the main thermostat

If I were to replace the two inline stats, and that solved it, would I need to replace the main stat?

No and you may be lucky.

Good luck with that as mine is on 70k miles and I'm thinking the main block stat may need renewal as it's a time consuming job so bet it's never been replaced. :sad1:

Mines on 43k and being replaced next week. Expecting three hours labour.

That's a bummer and it doesn't look straight forward either and there's me thinking the tt mk1 was a pain to do :laugh:
Thanks

Mines 105k :o
I was stupid as I should have bought one with higher miles as it would have cost me half what I paid for this.

Unfortunately is unlikely to be the two inline states, they only speed up the warm up of the engine so (in theory) you get warm air in the cabin and quicker engine up to temp. If the main stat was ok but her inline are bust then you would still run at 90 just take longer to get there. It's the main stat which makes it run cold, it keeps taking cold water from the rad when it shouldn't. My car ran at 70ish and dropped below slighting when cruising, changed the main stat and sits on 90. You can check if it's the main stat. When the engine is at 70 or whatever your running temp is now, have a feel of the rad core, if its hot the stat is open and knackered. Be careful about the fans coming on, they shouldn't but if the temp sensor by the main stat is shot the fans may come in early. you could always unplug the battery to not risk your hands :happy2:
-
Hmm it did actually get to 90 today after ages though.
So you dont think I should get the two stats? It seemed to have worked for others...
I have only asked for.vw to order them in, I dont have to purchase them do I?
-
If it gets to 90 and stays there then you are good. The line stats stay open once the engine is warm, the main stat regulates by open and closing depending on engine temp to keep it at around 90. You could in fact ditch the inline stats, not saying your should, but the car would just take longer to warm up. The main stat regulates temp once everything is warm and you are driving.
How are you reading the temp ?. If you are using the gauge in the car that's nmissleading, my car always read 90 even when it was 70 :laugh:, the car gauges read 90 at any temp from around 75 to prob 100 before they move. It's to stop people running back to the dealer as temp fluctuates through normal driving.
You need to read with vagcom or a obd reader to see what is really happening
The main stat is really common, you will find your turbo run on water pump won't run very often either. Loads of people think the pump is duff, when in fact their main stat has gone, car doesn't get to 90, gauge reads 90, ecu doesn't run the over run pump at 70 :happy2:
-
Mine is also doing this recently (96k) ,got it booked in to an independent next wk he said it's very common .
Cost is gonna be £250- £300 :surprised:
This car is costing me s small fortune !
-
If it's making tha gauge move its def the main stat, you will likely find its running at about 70-75. I have a friend who is a master tech at Audi, he does all the work on my car and changed the main stat. He has never changed a single inline stat but many main stats., read into that what you will :jumpmove:
It's not a simple job, it's under the inlet manifold so not a 2 min exercise.
-
Yes mate, that's exactly it.. The stat is open too early and not closing so the engine is getting over cooled by the rad.
Save your money and time on the inline stats

Thanks for the heads up. I'm going to look into replacing the main stat. Be proper chuffed if I manage it, and absolutely kicking myself that I didn't take it to a pro if it goes wrong. as always. Thanks

Yea, I am the same, thought about doing it but knew it would be a pain so got it done and sat at home drinking tea instead :smiley:
-

Having a look at the procedure - i'll be doing the same! I thought the main stat would just be a little bit harder then the inlines - how wrong I was. What a pain!
How much was yours?
-
Also, anyone have any thoughts on whether I should address this issue sooner or later, I was planning on booking the car in for a remap in December/January and was wondering whether I could leave it till after the remap/ once my wallet recovers, but am unsure whether r-tech would be able to get the most out of a remap if the thermostat is playing up.
-
Running cooler the mpg will suffer, the oil will be slightly thicker as the oil cooler is water cooled. You won't do any damage. But not sure about the map, I am sure they would want it at operating temp. Prob worth getting it done before the remap if you can.
-
I had a bash at doing my main stat a couple of months ago. Its actually not as bad as you think. Its just time consuming as there are quite a few parts to take off. If you just follow a guide and pay attention its really not so bad. I followed the instructions on Pelican Parts which were very good.
Solved my cold running issue but not my fan issue!
-
I watched the video from the first page where he does a lot of work from under the car. I cant imagine this being fun on axle stands... plus I need a locking pin for the cambelt.

Locking pin for the cam belt?????
-
I think he meant fan belt lol.
Does anyone know the size of pin used as you can use a nail, Allen key. etc.
-
Oh I thought you needed to somehow lock the sprockets the cam belt sits on in place when you take the belt off?
-

Not at all Peskyjones, it's the fan belt tensioner when your slackening and removing the belt. is all. :-)

Ok so you use the spanner to keep the tensioner in place. Whats the purpose of that? So you don't have to re tension the cambelt when you put it back?
-

You use a spanner on the tensioner to take the tension off the aux belt then slide a nail/allen key through the hole to hold it in place. I use an allen key.

Peskyjones the auxilliary belt and the cambelt are two different things. You will be releasing the aux. belt tensioner and locking it at which point you can remove the aux. belt. Might aswell change it when removed as they are cheap. Further down the line you actually should remove the tensioner aswell makes access much easier.
There is a fair bit of underneath work, but with correctly positioned axle stands its perfectly safe.
Wear long sleeves aswell... my forearms were cut to shreds on the front bonnet slam panel!
-
I see. yeah I realised that after these comments :ashamed:
By correctly positioned axle stands, where do you put yours? I put mine in the same place as this picture shows in the past
http://i.imgur.com/ayC4A.jpg (http://i.imgur.com/ayC4A.jpg)
Do you chock the wheels?
IF I do carry out the work myself I will definitely be wearing long sleeves - its cold when your working outside! Hopefully its not too cold to do it. Wish I had a unit to work in

Thats where i put the jack stands and yes chock the back wheels. Then give the car a shove to test its not going anywhere.
-
Thats exactly where i put mine. You can chock the wheels but leave your handbrake on, that should be enough. I had all four wheels off the ground to do coilovers so there was no requirement to chock.
Thankfully i had a garage to work in. Still super cold though but i had two fan heaters blowing on me!
Have a bash is all i can say. Hearing all the stories about the job i was very aprehensive to attempt it myself. Wasnt as bad as i imagined though. Its by far the best way to learn stuff about your car aswell!
-
Just had mine replaced...£300 gone :sad1:
But the car warms up super quick now and stays at 90 :signLOL:

Hi was that price from an indy ? which stats did you have replaced.
M
-
Yes at my local indy, had the main thermostat replaced.
Took my mechanic the whole day as he's never done it before :signLOL:
-
That's quite pricey but better than your local vw as they'd probably want double.
I would have thought no more than £200 if all three for the dsg and less for manual.
If he took all day then he's not very good at what he does :signLOL:
Thanks
M
-
What's a main stat cost? £35
Three hours labour I have been quoted at my indie and his rate is £33 an hour!
I'm expecting a £150 bill at the worst. (Manual car) £300 is mad imo!
-
I think the main stat is 50 quid. I'm going to get a few quotes. I don't have much time spare at the moment I think I'd need to dedicate a day to it, so as much as I'd love to be able to do it myself I think I'll bite the bullet and pay for the job.
-
My Indy has quoted me £250- £300 so seems about the going rate at a Indy.
Still a mad price though for a thermostat!!
-
That price is absurd folks :surprised: but I guess garages can charge whatever they wish. I certainly won't be paying silly money when I know well it's no more than 3 hours worth of work and as PT82 says £33 ph is a good price even if it took four hours.

Like all jobs they can turn sour so you need a secure/safe place to leave it until you can solve any problems that arise - I think to enjoy the challenge this is the wrong time of year for outside never done it before stressful jobs.
If you can get it done at a fair price go for it since there will be plenty other jobs to get a bit spanner rash on!
-
Just had my thermostat and housing done at Psi tuning today. I was having the same symptoms as you. The temp would only really stay about 70 unless you pushed the car hard then it would rise but would then drop again very quickly afterwards.
Paid £145 for the whole job fitted, however mine is a manual. I believe there's a couple of inline ones on the dsg.
The thermostat was stuck in the open position causing the fault.
-
That definitely sounds like the main stat as mine does exactly the same.
On the motorway it sits at 70. Rises in stand still slow traffic.

Cars going into an indy tomorrow for a diagnosis, they eant to do this before comittibg to the job
-
275 total all in. Car reaches 90 and stays there pretty quickly now.
-
Glad you've got it all sorted :happy2:
-

Pleased you got it sorted!
As a guide for others could you quote both your miles covered and time driven for the 90'c temperature to be reached after your repairs today.
-
Mine is going in tomorrow, expecting to pay the same sort of money.
-
Mine was in today , getting it back tomorrow now due to needing a new rad aswell!
I've had a coolant leak for a while now, garage told me the rad was pretty much shot!
So more expense !! But now will have new thermostat, coolant and rad.
-
Done mine today what a pain in the ass but all ok now :smiley:
-
Well got the car back today .. For about 30mins everything was fine .. Then low oil pressure light and warning came on!!pulled straight over ! :surprised:
Had car recovered back to garage ... Suspect if might be the oil pump!!
Not to happy to say the least as its just cost me £480 and now this !
This car might have to go ... :sad1:

That's a beech :surprised: I seruously feel your pain here...
what mileage you on if you don't mind me asking?.
M
-
Was that the recovery agents opinion as well - it seems just too coincidental or have you had any earlier warnings of oil pressure issues?
-
Car as just turned 97k had no issues before this with low oil level / pressure.
I'm hoping it may just be a problem with the oil pick up pipe.. Though I'm not holding much hope on this.
It is a strange coincident I'm now wishing in some ways I had left the thermostat as it was !!!

[/quote league isn't too bad. Hope it I'd thr oil pick up pipe although I never had to replace mine or clean it with the mk1 tt 225 many members did and many lost engines by not doing so as they didn't know what was going on and carried on driving to try get home.
I think I read another member having the same with his car after a thermostat change. I'll have to go on a search for it.
Good luck :happy2:
M
-
my old 05 gti would take a long time to reach normal temp when i did a search few years ago it was reported normal on this forum , when i got the ed 30 it would get up to temp im 5 mins of normal driving and stil does,
-
I never had this problem with the tt as it used to get to operating temp within the 3.2 mile drive to work.
I'm guessing the inline ones have failed if dsg it has two and febi ones can be purchased for under £20 If they are too expensive from dealers or TPS.
-
I have a spare inline stat. I thought my car had two but it only had 1. You can have it for £15 if you want.
Think i paid 20 something.

If no one wants it dazza I'll take it :jumping:
I have two on the dsg and every penny saving helps.

For that price I'd take two peskyjones :laugh:
No worries they're cheap enough from febi :smiley:
Good luck with the replacement and hope it works out for you.

-
I would have had two if he had two to offer? Ill replace the easy one, and if that doesnt work il buy the other from vw for 25 and replace that one.
-
If you have two i would change both together. G13 is not cheap.
Will get this sent out tomorrow.

Yeah I read that a while ago :happy2: the gearbox one looks easy but the other may be a tad tricky. Think ill wait till the weather improves. It still gets to ninety and stays there 90% of the time it just takes a while
