PLEASE HELP Audi A3 1.9tdie 105bhp

[Rob1997]

I have an Audi A3 1.9tdie 105bhp 2009 105k on the clock

i have white and black smoke when the engine is cold and when it’s gets hot it starts kicking out blue smoke.

the car starts poor and misfires most times at idle hot or cold, also will stall at idle occasionally and also when driving, again hot or cold.

i have replaced the fuel pump as it failed a few month back, as well as the turbo. I have gave the car a full service and I have taken off the EGR valve and cleaned it.

I’ve been scratching my head since this problem started a week or two ago, any help would be greatly appreciated.

new to this site, help me out

Post up your engine code and if you have dpf, which fuel pump was replaced? In tank or on engine?

[Rob1997]

I am not 100% on the engine code I will find that today, it has a DPF as it was the uplift pump in the tank that was replaced.

Cheers

Engine Code is BLS.
