Idle speed varying with a/c on, and seat vibration - 2.0T
« on: 17 July 2019, 08:25:36 PM »
I've posted on here about this before, but I noticed that the idle speed seemed to fluctuate at idle in traffic. I think this is due to the a/c and cooling fans coming on and off. But at some speeds (probably normal idle speed around 70rpm ish?), I would get vibration through the seat. This was also fluctuating in nature, and someone suggested it could be my balance chain....which I knew needed doing as it had previously been reported as being noisy from cold start.

I had the chains done, and I'm not sure if this seat vibration is any better. It is still there, and the idle speed still fluctuates.

On another thread I've just started on here about suspension and startup knock that I get, could it be that one of the engine mounts/bushes on the driver's side is actually the route cause of all these "issues"?
