Hi Guys,

I have R32 BUB engine in my Mk1 golf and it vibrates the whole car :O It is not not-drivable, but i can't see anything in the mirrors and the dashboard sounds like it's coming apart

So when I build the car last winter I started with a used Flywheel from a Passat VR6 and clutch, and i don't remember it being this vibrating. I then disassembled the car for paint and together with that I changed the cam-chains and bought a lightened flywheel with a Sachs clutch:
SACHS 3000384001 KUPPLUNGSSATZ VW GOLF

The VCDS don't show any DTC's and no misfires detected.

I fear that the flywheel/clutch/crank is out of balance :O Has any of you guys any experience with out of balance flywheels ?

It is four sure engine related, it follows RPM's, really bad around 3000, and then not as bad in high RPM.

Can anyone tell me how to troubleshoot on this? Can i use VCDS to something ?? Is it normal with a lightened flywheel to increase vibrations ? I really don't wanna pull gearbox of and put the original VR6 flywheel on if thats not the issue...

The engine pulls nicely, but could it be a cylinder is behaving badly ?

Any ideas is welcome....

Thanks

I would use vcds to look for misfires first. Engine balance issues usually get worse with rising rpm.

What condition are the mounts in?

Thanks for Reply guys...

The mounts are brand new from Eurowise. When fitted the front munt I needed to really push the engine back to mount, maybe this could be the issue, I will look

VCDS detects no misfire...

Is it possible to Troubleshoot on injectors ? What if one of them is behaving badly ?
