Audi a6 c5 2.5tdi avant slow start and smoke problem
What could be the problem? Every morning or when engine gets cold is the same as shown in the video. Car started to give lots of smoke after diesel injection fuel pump was changed. At first i thought that oil is leaking somewhere but it isnt, same with the coolant and smoke stays even when engine is at its operating temperature. So two main problems:1. Smoke2. Slow start of the car.
