Hi, Just joined the forum and its my first post, so go easy.................. I've got a 53 1.9 TDI Sport 130 and recently the engine managment ight has come on. The 2 errors that vag com show are 1764 coolant tmp sensor, this sems a reatively common one and the other I havent found on any forums yet, 17106 transmission output sensor - no signal. Any ideas on, a) where is it b) the effect on the car (appears to drive ok) c) cost and fitting. Any help would be much appreciated.
