Engine Shaking after Cam Belt Change!!!

[danGT]

Hello All,

OK I really need some help here.

I bought my 2005 2.0 GT TDI about 3 months ago, I bought it from a main dealer for Seat and Skoda.

I received a reminder from VW to say the cam belt was due so after a bit of negotiating on price I booked it in to have the cam belt changed along with the water pump just for piece of mind.

When I picked it up it was driving fine, but when I got home and the engine had got up to normal operating temperature I noticed a weird shaking coming from the engine at idle and anywhere up to about 2000rpm.
It seems to come and go every 2 - 3 seconds, there is no change in RPM nor can I hear any strange noises but I can definately feel the shaking.

Since then the car has been back to the dealer twice for them to sort it out, the 1st time they re-positioned the engine mount and said it was fine, got home, same problem.
The 2nd time they checked the timing, the mechanic and two salesmen drove it and said they couldn't feel anything, I felt quite re-assured by this, but, when I got home It was still juddering.

I am getting very fed up now and have said to them that I will go back Friday afternoon and take the mechanic out myself, you can feel it quite easily from the passenger seat.

Any ideas anyone, I really need to go back to them with some ammo.

Sorry for the length of this post but I had to get everything in.

Looking forward to any help.

Cheers

Just bought a 2005 GT TDI with 67k on it and it has this same problem. Doesn't do it when you start the engine from cold but as soon as it warms the shake starts. Going to have my mechanic take a look at it. Have been searching the internet and it seems to be a thing that happen to some of these engines. I am just hoing the timing is off a bit.

Hi Benny,

I found out it is a timing problem if you have VAG COM go to the engine measuring blocks group 004, the last box along is Torsion Value, Mine is showing -4.9 deg KW, this means the timing is retarded, it should be between -2 and +2, although many owners have reported that the best value is between 0 and +1.

Look at this link to see how to make the adjustment, If i dont get any joy from my garage today I will be doing it myself this weekend.

Good Luck!

Thanks Dan for that info will let you know how i get on next week

[danGT]

Thought I'd better post this follow up.

I took my car back to the garage, they agreed to re-install the cam belt.

I got the car back with a torsion value of -3.9 deg KW, better than it was, I still have the shaking though.

Thought I would do it myself following the guide in the link I added previously, took the cam belt cover off only to find TWO cam sprockets.

Does anyone know how to make the adjustment on my twin cam engine???

I am getting so fed up of this now.

Looking forward to any help :1zhelp::1zhelp::1zhelp:

What is the engine code?

[danGT]

Hi kenney,

It's VWZ7Z0E1911630

[kenney]

That is not the engine code,look on the sticker on the timing belt cover for a 3 letter code BDK,BKD or similar,

[danGT]

Sorry its BKD 418 175

[kenney]

The camshaft sprockets are positioned with 2 locking pins,with the engine on TDC,loosen the 3 screws on each of the sprockets,and adjust the belt tensioner,tighten the 6 screws on the sprockets,making sure the TDC marking does not move.If you send your e-mail address i will post you the diagram,which will make it easier to understan

[danGT]

Hi kenney, that would be great its

Is anyone experiencing a loss of power with this engine shake. My wife drive's the same car as mine hers has 48k on it and not a rattle and mine has 69k with this shake. Mine doesn't have as much lift in the lower gears I am thinking it could be to do with the turbo. Any thoughts.

Hi danGT
If you don't mind me asking... how much did your cam belt / water pump work cost?
I need to do the same

[danGT]

Hi Architect,

I got a reduced rate on mine as it was due a month after I bought the car, but my local VW dealer quoted £450 and a good local VW specialist £300, I got it for £200 in the end, but wish I had gone with the specialist considering the problems I had.

UPDATE!

Hey Guys, another update, I cant believe i'm still having this problem!

I took the car to a local VW specialist and asked them to check the installation of the cam-belt.

They said the installation looks fine but they haven't used genuine parts!

I'm now stuck trying to prove that I asked for genuine parts originally, (rock and a hard place situation).

Anyway since then I have had the EGR valve off (at the recommendation of the VW specialist and cleaned it, they said it could be this) but to no avail, they also checked the DMF which seems to be fine.



My question is has anyone here had any problems with 3rd party parts, specifically Dayco Timing Belts?

and do you think this is the root cause of my problems.

I look forward to any Ideas and Help

Dayco IS one of the OEM manufacturer as Audi/Vw dont make belts and tensioners, they are just putting the car toghether with parts made by 3rd parties to their own spec ! I suspect there is an injector misfiring or the flywheel is on its way out-if it does it when the engine is hot !

[VAGMAN54]

did they put the pins in ? you carnt tell just by looking !! did this prob happen straight after the belt change ??

[danGT]

Yeah thought they might have been but at least you still get a warranty with VW branded parts.

Had another VW specialist look at it, they ran a diagnostic and checked the DMF so don't think that could be the problem.

It did start straight after the belt change.

[VAGMAN54]

how did they test the dmf ?

[danGT]

I cant remember exactly how they tested it but said it was to do with operating the clutch with the engine on and off load whilst checking for vibration etc.

It would be some variation on that, but like I say I cant remember exactly what they said.

[VAGMAN54]

to be honest the only way to test it is to take the box off otherwise it a guess

[danGT]

Yeah they said it was a valid test but to be 100% they would have to take the g/box off.

Only problem is thats more expense.

[danGT]

One thing I have noticed though is it gets a lot worse when the A/C is off, or the temperature outside is less than the temp set inside.

i.e. when the compressor is not running, so less load on the engine it is worse.

When it is running it seems hardly noticeable

Strange

[phil_87]

I am having exact same problem with my A3 ( i know its wrong forum :p) when cam belt got changed it started to shudder when hot, while idle at lights, and only yesterday I turned A/C off while waiting at lights near my house, and it shuddered more then it normally does, like u described above. tho cant find nothing wrong, prob cos they dont let it get hot :p.

Anyway if i find a solution I will let you know, as it seems exact same problem.

[danGT]

Hi Phil,

Sorry for the delayed reply.

Did you find a solution?

I have only noticed the shaking again today, after the heat wave, when the air con was used continuously!

It must be only when the engine is off load.

I have been back to the garage again who as you say don't let the car get warm, of course mine didn't shake on that occasion typical!!

They have offered to buy the car back from me... Probably so they can sell it to someone else without fixing the problem. Makes me sick!

I am considering taking the car to VW and just biting the bullet by having them do the job again.

Did you have your belt changed at a main Audi dealer??

[phil_87]

Not yet, gonna phone a mechanic who i use to see if he can tweek the belt a bit,

No my belt wasnt done at audi dealer, so i asume that might be the problem, so mb need to take it there see if they can but one on, but gonna try the mechanic first see if he can do anything with it again, even if it wont shudder when he comes :p

keep you updated what happens anyway.

Hello, I seem to be having a similar problem with my Audi A4 2.0 tdi 140. Can anyone help with the Torsion Value please. The engine code is BRE.

Thanks, Nige

Sorry i seem to have posted in the wrong forum.

[Bakers VW]

Hello I am getting the shudder problem as well. I have a 2006 mk5 gt tdi 140 BKD Engine code 39500 miles on the long life service plan. I get an intermitant shudder when idling. It mainly seems to occur on inclines and only when hot but not allways. If I depress the clutch it makes no differance. The belt is due for change sept 2010.

I have a BRE with 243,000 Km it shakes when idling. I just had the box out recently as I thought it was DMF, But the mechanic came back and said there was no wear in the DMF only that previous mechanic had not torqued it correctly and the bolts were loose. So he replaced the Pressure plate and Clutch plate. It goes much better, but the wobble or shaking on idling is driving me mad! When I accelerate rather hard the gear lever wobbles around too. What is not normal? Apologies for the thread jack.
