Car vibrating with at idle with clutch down and in gear.
Discussion
Hi all,
For once not a problem with any car that I own
A mate of mine bought a 2004 Audi A3 2.0 tdi the other day, and took me for a spin. I noticed that if he came to a stop, say in traffic for example, with the engine idling, clutch down and in gear, that after a few seconds the car would begin to vibrate or 'pulse'. I'm afraid it's quite hard to describe, but it wasn't just the normal engine vibration. I suppose you could say it felt like mild clutch judder, if that makes sense. I know judder when setting off is a classic sign of DMF failure, but this 'pulsing' only occurred when stationary, and after a few seconds.
I had the same problem on my old Passat (with more than double the mileage) and always wondered what it was. At the time I thought it could be the Dual Mass Flywheel, but wondered if there was anything else it could be. Trawling "da interweb" has not revealed anything on the subject.
I would like to find out just to satisfy my own curiosity, and alert my friend to it.

I have this issue on my Golf - I believe it could have something to do with the heatshield on the exhaust?
That's an interesting theory, how does it make the whole car pulse?Triumph Man said:

Not too sure tbh, there is a thread in the audi,vw&seat forum regarding this. Have a quick look.
Ah brilliant will do, it's a common issue then?Here's the thread.

That's very kind of you, but to be honest that doesn't sound like the problem at all. It's certainly not a rattle, its more a judder that can be felt but not heard.Y282 said:
engine/box mount would be my first thought. have a bloody good look/lever, they can be quite hard to spot.
That's my suggestion as well, any play in the bushes in the mounts can lead to engine vibrations through the cabin, some bushes are notorious when it comes to seeing if they're fatigued.The pulsing vibration is the engine firing the injectors to keep turning, creates a nice little sort of lull.
I know this topic was set up a long time ago but i am having the same issue. I have a video on YouTube this is the link

If anyone has any ideas on what the issue is I would be very grateful if you could help me out. The engine starts to vibrate and judder really bad when the car starts to get warm. I have noticed if I put my air-con on it will put a load on the engine and help to reduce the juddering and shaking.

DMF has failed in all likely hood by sounding of that.http://m.youtube.com/watch?v=aMB9QQBwOEY

I hope not as I had it changed in month into a single fly wheel conversion. It's intermittent and only really does it when it's warm.but I've tried pushing the clutch down down to see if the noise would stop like it did when the dual mass fly wheel went but the sound and jerking just stays. No change what so ever.
See I thought this at first and took it baco to the garage and they said its not the flywheel we have done plenty single flywheel conversions. And they said its intermittent so it wont be my clutxh and that it doesn't go away when the clutch is pressed down. I can't win its driving me made trying to locate the issue. I was thinking maybe injectors but im not sure now you're saying flywheel.
A little list to start you off;
Dual mass - potential but a lot of vibrations from the 2.0 tdi get blamed on it that have no connection
Injection system - It's vastly complex and needs someone (not audi) to look at in that knows what they are doing, could be injector seals, a dicky injector, a dicky pump or one of its components etc etc
Inlet manifold - swirl flaps could be causing issues
Cylinder head - these can go porous causing issues
Vibrations/Judders on the 2.0 tdi engine are common, they are often lumpy at idle and can be extremely difficult to diagnose why. They need someone that works on them day in and out to diagnose properly, unless you have a very good well regarded main dealer with a master tech that is above the normal bar I'd get rid of it (which is obviously what the previous owner did).
Expect to spend at least £1k fixing it, less is a bonus but more is possible !
Good luck
My car is a 1.8 tdci Ford focus. Which I must say is the worst car I've ever had problem wise.
Id say its more of a misfire rather than a vibration to be honest just that you can feel it through the driving seat. Its like the car wants to cut out but doesn't and it really shakes the engine alot. As soon as I start driving it will be fine no problems with power what so ever. It will only happen when tye car is sat at traffic lights for example and when the car just gets over the 1/4 mark on the thermostat
