I have a 2004 touran 2.0 tdi 140bhp and i have an intermittent starting problem. It only happens when car is started first in the morning when its cold and the car will turn over for a second and stop turning over with a thud as if i stalled the car at traffic lights in the wrong gear. If i try again it will do it again and usually on the 3rd attempt the engine will turn over and fire into life. I've had the battery changed a month ago and a new starter motor last week when the car did the thud thing again when trying to start it but at the second attempt when the key was turned there was nothing. The starter had burnt out. Got a new starter and the same thing has happened again today. Anybody any idea's?
