Audi S3 8L (BAM Engine) 52 Plate Revo State 1. Was driving along the M25 and shifted down to 5th gear to overtake a vehicle, as I then shifted to 6th gear the clutch pedal felt very spongy. I got caught in traffic, and had to turn the engine off. After about 30 minutes, I turned the engine on, and the car started to vibrate quite badly and I had thought I had blown one of my coil packs. Got back home, I revved the engine between 1000 and 2000 rpms, and the whole car started to shake really bad, loads of vibration through the steering wheel too. Iâm convinced that my BERU coil packs are ok (only 6 months old), they donât smell burnt. I removed each connection from the coil packs, engine idled roughly, as you would expect from a blown coil pack. Spark plugs are only 2 months old, had a little spec of oil on one of them. I serviced the car 1 month ago, plenty of oil, marked on the maximum of dipped stick. Engine management light is off. Thereâs no egg smell or white/blue smoke from exhaust Revving past 2000 rpms, engine smoothâs out. Holding clutch pedal down (still feels spongy) while revving engine, engine still vibrates between 1000-2000 rpms (Clutch master cylinder was replaced few years ago) I have suffered from clutch slippage for the last 4 years, but thatâs intermittent. Engine mounts & dog bone mount looks ok too. From the above symptoms, do you reckon Iâve knackered my dual mass flywheel? Do you have a possible idea as to what the issue might be? Thanks.
