Audi a4 b7 3.0 tdi quattro problem

[Wayneeboy88]

Hi all this is a question about my mom's Audi a4 b7 3.0 to Quattro.. when idling in traffic the car starts kicking out white smoke but we're sick of spending money and having diagnostics, at first I thought dpf problem so had a dpf removal and delete, still didn't fix it thought might have a dodgy injector because the first guy who diagnosed said dpf and number 3 injector, we've had it diagnosed by a vag car specialist today and said all injectors are actually really good and no fault codes on it at all. It doesnt lose water or oil so getting frustrated because nobody can figure out what the problem is, any ideas people and help would be appreciated, thanks.

White smoke at idle when the car is warm is usually a symptom of knackered injectors.

The smoke is unburnt diesel and it's over-fuelling.

Has it been remapped?

When they checked the injectors, what faults were present?

Hi there were no fault codes at all on it, and all the injectors were good. They read around 1 or 2 whatever that means.. It has been remapped at Midland remap with dpf removed and deleted.
