I have a 52 plate Audi a4 1.9 tdi estate
I have noticed that my car has started rough idling, it doesn't do it every time I get in the car and start it.
But when I get up first thing and take my daughter to school it's fine, no rough idling but soon as I get back into the car later on to go to work it starts doing it.
The car shakes quite bad but once I start driving the car, eventually it clears up and drives normally ??????
I changed the fuel filter today thinking maybe a clogged filter but no no change. Also I have been putting in Vpower and Valvoline injector cleaner in to clean injectors. Did this almost a week and a half ago. still the same
Car has also been on full diagnostics and there are no codes stored
Also serviced 6 months ago new oil, fuel, air, pollen filter, new glow plugs, antifreeze and has been serviced every year without fail, every 9 thousand miles.
Other new items, clutch and turbo replaced 6 months ago
I don't know much about cars and have tried to put as much info as I can
Thanks in advance
