Right guys was in the car yesterday gt tdi pulled over on a very quite road and set off with some revs next thing here a loud snap or bang and tons of white smoke coming out of the exhaust pulled over instantly and inspected car engine sounded fine when turned back on. Smoke starts to clear so I thought I'll be able to limp home, so I thought turned car round next thing it sounds like I just dropped a bag of spanners in the engine. So pull over straight away, next thing the engine starts revving it's nuts of almost redlining itsself. At this point I shat myself and turned engine off. The next bit is still giving me nightmares, the engine carries on revving. I'm stood there looking at my motor key in hand while it's sat there revving it's self into outer space. The only thing I could do was stall the engine and ended up getting towed home. Anyone have any ideas, oh and my warranty as just ran out
