I bought a VRS on 124k on Sunday.

 

The tracking was out and felt it needed the wheels balancing again.

 

I had the tracking done and the front wheels re-balanced and that sorted the driving/movement judder/wobble.

 

Now the problem seems to be when doing approx 40-50mph+ and accelerating more than 10% throttle. Feels like a juddering through the car.

 

I have read other threads about this potentially being the Flywheel and needing a DMF upgrade?

 

Just want to see if there is anything else I can try prior to big bills like that.

 

Cheers,

 

James.

Nobody?

What revs are you accelerating from?

I did some more testing on the way home. Seems to only do it over 3k like 3/4th gears

Failing DMF symptom is usually an arrhythmic "cement mixer with bricks" sound on idle or thereabouts.

 

From what you've written, this feels like something else. NFI what though .

Yea sounds and drives smooth most the time, just those rev ranges and gears mainly. Could do with jumping in another locally really.

Its had a recon turbo if that might be anything to do with it...

Silly thought but, are the rear rubber mounts on the front wishbone/s in good condition, trait of this model to failure, and effect steering control..?

Plenty of info on this site to replace etc..

 

 

Odd times the dog-bone rubber mount has been known to fail.

Keeps engine from rocking under accelaration/ deceleration ?

This is what I thought of last night that it could be dog bone mount or similar. I'll have to get it up on a ramp soon and have a look at the bushes etc. Standards good enough to fit again?

Uprate the rear wishbone bushes, console bushes they are called.

plenty of info on here or Google about upgrades, either aftermarket or Audi/Seat solid ones rather than the standard voided bush.

Could be worth checking your gearbox mount for your engine vibration aswell as dog bone mount.

I would fit a uprated dog bone bush, much tighter gear change and less engine movement, only downside is slight vibration at idle, but only takes couple of days to get used too

Thanks very much.

 

Will get searching about for some parts then and try get it sorted sooner rather than later as thats the only niggle it has other than the paintwork needing a decent machine polish.

Another thing to try is to dip the clutch when you are feeling the vibration, if it still vibrates your problem is not related to the engine/gearbox/mounts etc.

If I let off the accelerator when it starts, the feeling stops.

 

Thats why I thought it was the wheels/tracking causing the problem. 

If it's wheels/suspension it will usaully do it all the time, no matter what the engine is doing.

I'm going to see if I can meet up with a mate close as he has one also. Can try see if/what the differences are then.

 

The guy I bought it off mentioned about the EGR being mapped out the car (although it isn't remapped?) so maybe thats clogged up or even airfilter?

Whilst detailing the car at weekend I had a quick look under, looks like the rear wishbone mount is polybushed.

 

Just need to get it on a ramp to check all the rest of them.
