I think i have the same problem, had to get towed home last week, on the day i was going on holiday..
just had a look at it today as i have got back from holiday and my 197 just wont fire, it turns over.. had a computer on it, brought back no faults..
had a quick look for this TDC sensor but cant seem to find it.. have not had a real look under the car yet but took the air filter out and still cannot see it..
can anybody point me in the right direction? its a 2009 197
thanks in advance
