golf gt tdi 2.0 140 rough idle

[idcwales]

hi newbie here just wanting a little help i have a golf gt tdi 140 2004 after i bought the car after the long journey home i noticed it was idleing really rough and sounding like a slight missing what could this be ?:confused:

[paul.mgrath]

Mine did it, it was as though it was in gear and the clutch was biting slightly, if i touched the accelerator ever so slightly it went. I was told of a VW ECU update (free) and this cured it. Be careful my local VW dealer tried to charge me 90 quid. I went to where i bought it from and they did it forvfree. Takes about 2 hours.

If you ring VW with the chassis number they will tell you if it has been done.

Hope this helps!!

been to vw today and been told there is no update to sort this out what else could it be ?:confused:

[tdci115]

I am in the same boat, im wondering if its a DMF issue.

I have had all the updates and get a 'cannot fault the vehicle sir'.... all this from a 2008 2.0.

[paul.mgrath]

I found out through the forum about this update, i didn't ask vw to do this to cure the fault (specifically saying my car was juddering) i was just told on the forum by others that when this update was done their fault went.

maybe worth a call to ask vw if there are any updates available for your car?

Other than that i don't know but i had exactly the same problem as you and this update did cure it.

[paul.mgrath]

I had a problem with mine and it sounded like a tappety rattle from the bottom of the engine gearbox side. I was told this was the DMF common fault!!! Nothing to worry about (05 3.5 yrs old with 36K on the clock!!!)

Thats when i decided that it was time to go! Now got a mk6 and as soon as ANY noises become apparent - straight in the garage rather than live with it!

That new CR engine though is much quiter than the pd

[tdci115]

Mine just sits there shaking the car when at junctions etc, no more updates available, so im sure its mechanical ie DMF or injectors, i get the feeling im being fobbed off?

Anyone think im mad :biglaugh:

[idcwales]

my car is still in vw today so i have been there and asked them to find this problem out as its doing my head in. At traffic lights and stuck in traffic with this rough idle so lets see if vw sort this out, i dont think it is injectors i think it is the dmf out of balance because when the car ravs past 1400 rpm its smooth as anything and drives very well on the motor way at 70

i also have the famous ticking sound from my climate control was told i need a new climate control unt the joys of a 2004 golf gt tdi 140 lol

no the car drives lovely as normal except on tick over the warmer the car gets the worse it happens

hi,
just a quick update i have found out that this rough idle is the DMF not a common fault as told be vw 1 in 100 this might happen too, My friend in a clutch and gearbox garage has done 3 so far, When i have finished wiping the tears from my face and the shock of a £1200 bill for a new one plus fitting. Why cant vw do a solid clutch like the peugeot 307s that had this problem :mad:

[tdci115]

Hmmm, sorry to hear that mate, wonder if mine is the same.... need to badger VW.

[Tigerman]

What is DMF?

I've noticed very slight idle speed fluctuations on several VAG cars. I think VW aims employ insensistive staff 'cos they couldn't even feel it!

(No offense intended)

[danGT]

Have a look at my thread I posted a while ago....

http://www.vwaudiforum.co.uk/forum/showthread.php?t=70226

Incidently I'm having the belt replaced on Wednesday!

[paul.mgrath]

what is dmf?

(no offense intended)

dmf = dual mass flywheel

[tdci115]

I dont know how they cant feel it, unless they dont even test drive them.

The cambelt could be an idea, although it would have had to be put on incorrectly at build, although judging from my rattly interior why would they build the engine properly :biglaugh:

hi ,
car is finished today had new dmf and clutch ,dealer reckons been out in the car let it warm up and no more rough idle ,cant wait to get it back may be i will feel better after having it back after that big expense and hope it is sorted :(

Please let us know tonight if it has cured the problem, having my belt done tomorrow.

The dmf on mine was checked and seemed fine.

[idcwales]

sorry cant collect the car straight away as i am working far from home but will post on here as soon as i have tested the car myself ,like to do a good run and see what happens when i get back ;) not holding my breath though ,we shall see

hi there, my audi a3 2.0tdi 140 2003 110000 miles had the same faults,took car to independent vw/audi garage who said dmf,had dmf fiitted with new clutch fault now gone .

[idcwales]

hi,
had car back now with new dmf and clutch went for a long drive left the car ticking over for about ten minutes and go to restart the car and guess what ? my car would not start had to let it turn over for a while to get it started ,oh well time to go back home get back home let the car idle and surprise surprise rough idle still there any way turned car off took ages to start again when it did it stayed ticking over at 1000 rpm and would not drop until restarted any ideas now anyone :zx11::mad:

[danGT]

That is such bad news, really sorry to hear that. :(

I got my car back today and it turned out that the timing was off, they replaced the belt, because I wanted genuine parts, installed it correctly and touch-wood it seems ok.

Maybe this could be the cause of your problems.

Perhaps you could go back to the garage and tell them that the problem hasn't been fixed (plus the other troubles you got) point them towards the cam timing, tell them to check the torsion value using there VAS system, VW recommendations are between -6 - +6
Mine was -4.7

After cam belt change mine was -1

When the specialist I took it to called VW technical they said it is important to be as close to 0 as possible.

Hope you get it sorted.
Let me know if you need any more information.


Sorry cant help on the new problems though.

[idcwales]

thanks for that dangt just ******* my off and the rough idle is not there all the time comes and goes after every time you start it up does not seem as bad as it was just £1500 later this is the most expensive car i have ever had and i have had 11 cars maybe time for some bad luck lol :mad:

[idcwales]

hi,
been back to vw and they said car is ok dont expect this car to run 100 % smooth as its a 2.0 litre diesel pd engine and the bad starting from warm is the temp sensor have one on order let you know the outcome cross fingers :(

[danGT]

hi,
been back to vw and they said car is ok dont expect this car to run 100 % smooth as its a 2.0 litre diesel pd engine


Rubbish!!!

Mine is running perfectly smoothly, somebody correct me if i'm wrong but wasn't this engine marketed in europe as being one of the smoothest diesels ever made???

Do let us know how you get on, get them to check the torsion value and let us know what it is, should be as close to zero as possible.

Good luck

[tdci115]

"somebody correct me if i'm wrong but wasn't this engine marketed in europe as being one of the smoothest diesels ever made"

i wish!

[danGT]

Just going by what a friend of mine said, he lived in Germany for a few years and he was sure the advert was a 2.0 PD with a glass of water on it, might be wrong though but mine is very smooth

[idcwales]

hi,
my car is now back at vw with the warm starting problem and slight rough idle was told to change the temp sensor done that no different:mad: lets see what vw find did tell them about timing cross fingers this time and lets hope i do not have a big bill like last time :confused:

[danGT]

I've got my fingers crossed for you, I'm positive if they can get the torsion value as close to zero as possible it will sort the problem once and for all... Or until the next cam belt change.

[idcwales]

hi,
vw phoned today, had the car out today started ok after a run still has a bad idle no mention of this just sorry sir no faults found ???????:zx11: what about the timing been out ?? dont think so they said no faults showing like cam senor or crank sensor fault if the timing was out,why dont vw belive there is no fault just because there fault finder does not pick a fault up .now they have said maybe crank sensor after my changing the temp sensors ,yet you can sit in the car and feel the bad idle if vw cant sort this wot hope do i have ????????:mad:

[danGT]

Ok first tell them not to bother doing another fault reading, a fault will only show if a value is outside the set specification, as an example my torsion value was at -4.4 before it was sorted, it is now at -1.0 and the rough idle stopped.

The specified value on the fault finder is -6 to +6, but if they speak to VW technical they will tell them that it should be as close to zero as possible.

It seems that a torsion value anywhere between -2 and +2 will result in a smooth idle.

Tell them to to use their VAS system to "Read measuring value blocks"
On that list they should be able to find "Torsion value"

Hope this gets you a bit further

[idcwales]

hi,
went to fit pins in my 2 cams today and they both would not go in one cam is about a tooth out could this be the answer to my problems at last car is booked in to vw on monday to be re timed :confused:

[danGT]

Yes that will definately be the case, if you can pm me your email address I will send you a VW work instruction on how the cam timing should be set.

[idcwales]

hi,
vw dont know what torsion values are when i asked they said they just lock the crank and put the pins in the two cams ??:confused: and they also said cant be timing out as no faults logged ????????
