Mend Audi A4

poor start up on 2001 Audi A4 130bhp diesel?

My Audi A4 130 bhp diesel is a lovely car with only 56000 miles. it runs great but on start up, especially when cold it only starts on 3 cylinders and smokes heavily. once you driveit goes on to 4 cylinders and the smoking stops. Any ideas

Sound like a dribbling injector, Quick, cheap fix, buy some Diesel injector cleaner. Warm the engine to running temp 90 degs approx. Add a small amount of cleaner, neat into to the Fuel filter. Drive the car hard, for atleast 10-15 Mins to clear the system you should see black smoke in your rear view. This should be a quick/cheap fix, if not more expensive intrusive maintenance required.
