Vibrations in cabin

javiseoane · 8th May 2018, 16:44

Hi, I have vibrations in cabin, engine lower Mount and uppers replaced and continuous vibrations. Noticed slipping clutch. Engine resonance at 1800 rpm until 2000 rpm.

So, Could be worn gearbox Mount? or DMF?, please I need help.

Thanks

How many miles you done ? are the rubbers replaced with oem ? dmf very rare unless your a clutch rider.....gearbox mount def replace easy to do dont use powerflex as they will vibrate on that mount...my opinion.....

It could be either one but you usually get clunks etc with a failed lower mount.
Although I agree It's rare for the DMF's to go, I've had to replace a few for various reasons.
When you say you've replaced the upper mounts aswell, you mean the Hydramount yes?

Oddly enough, I had an Audi A3 tdi in last week with a very similar vibration.
The customer assumed it had a misfire based on a diagnosis from another garage.
I was recommended by someone & he brought it to me.
On idle, you could feel a slight vibration going right through the car & this became more prominent when the RPM was raised to around 1,200-1,400RPM.
No other symptoms, no clutch judder, no rattles.
New DMF & clutch kit, job done!
