AUDI A3 2.0 TDI DSG 170: Hesitation, delay in power and delay in car moving forward Sign In

Hi fellas,

I have an 07 plate 2.0 tdi s line 170 dsg BMN engine code

Symptoms:

When I start the car first thing in the morning, or after 6 hours of not driving, the car does not move forward, it tries moving forward but it just hesitates. After 1 minute, it drives ok, and then on it moves fine but just from standstill, until it warms up, it jerks forward a bit. It changes gears fine, no delays, paddles work etc.

delay of power when pushing the accelerator down, then after a few seconds it becomes really responsive and all the power comes back

when it shoots off after the unresponsive phase, to the responsive phase, it chucks out black smoke

once it gets going it is fine. no noises, no gearbox issues.

around 50mph and onwards it starts to hesitates, like a pulling back, still reaches good speed fine, but it's pulling back and hesitating when pressing down on the accelerator hard

coming up with a P2626 code on vagcom, which indicates "Heated Oxygen sensor (Bank 1 Sensor 1) Pumping Current Trim Circuit"

Don't really know what to do with this code at this point, as I clear it and then a few miles later it comes back on

Really does relate to this article on this particular fault, but obviously that's just a generic article and every situation is individual I guess.

Any thoughts?

TDI wasn't available in the states for the A3 for that year and this forum is US based. No service information.
