Hello!
Does anyone know what the error code 2211 means for the Audi 100TDI (Type 44) 1T engine? When I read the memory, I always get 2211, even if I erase the memory and then turn the ignition on again, I get 2211 again. A friend told me that it was the needle position sensor

and suggested that I measure the resistance with the engine warm, the values should be in the range of 80 to 120 ohms, but I have about 110 ohms with the engine warm??? Is it really that, or is it something else??? Can it be checked somehow, or do I have to replace it directly? By the way, the distances are 50TKm.
The reason why I read out the memory is that sometimes a strong jerk is observed together with a stronger backfire!!!
P.S. When I turn on the ignition, I can hear the fuel pump making a clicking sound for about 1 minute, and then it stops. Is this normal, or is it related to the above problems?
I'm already a bit of a tinkerer, but when it comes to the electronics of TDIs, I'm unfortunately HELPLESS
Hi BLT!!!
