Had a low coolant warning on the Superb today. The coolant level in the expansion tank was ok. Stopped and started the car, and the warning disappeared. I had the same issues with both an Ocativa MK2 and Golf MK IV, and always at cold temperatures (-10 and lower) Is this a known VAG issue?

I may do it sometime soon. It may be that my insurance cover the injector failure. If not, I will just buy a new injector, and change it myself. It seems to be an easy job.

unfortunately no. I was a bit in a hurry, so I did not ask either.

Had the car at the dealer today. Measuring injector quantity showed bad injector on cylinder no. 1.

Have booked next week. I'll give an update afterwards :-)

The car has done 135.000 km. Oil change about every 15.000-20.000 km. I guess this would happen not only on cold engine if the engine mounts was the culprit? I will do a general scan to see if anything shows.

I have a CFFB (2.0 TDI) that when on cold engine makes a strange rattle/tractor sound on medium throttle. Also when accelerating the car judders and feels like it have less power, as if it do not get enough fuel or something. This only happens when engine is cold, and only the first few accelerations. The first that comes to my mind is injector(s). Am I on the right track you think? I do have a genuine VAGCOM cable. Which parameters can I use to diagnose fuel delivery/injectors? Thanks!

Hi, A late update on this. It turned out to be the head gasket. It completely blew on 405 000 KM. I ended ut with scrapping the car.

When engine is cold the coolant level is correct. When engine is warm all coolant dissapears from reservoir. When opening the cap the coolant reappears in the reservoir. 2.0 tdi BMM Any ideas?
