Hello everyone!
New to this forum so please if I do anything wrong, give me some advice on making corrections.
Im in a need of a little help with my Audi A3. I have a problem with excessive fuel consumption somewhere around 9l/100km. One time the car threw a CEL light and then it went off the same day.
The computer has a stored fault code which is

1 Fault Found:
18111 - Oxygen (Lambda) Sensor B1 S1
P2237 00 (096) - Pump current Open Circuit
Intermittent - Not Confirmed

Right now the car is not displaying check engine light or anything, when we clear the faults, it comes right back.
Its a CUNA engine code 184hp diesel, dealrship said that the sensor was replaced in 2017 due to recall of AUDI, is it just a matter of replacing sensor again or should i dig deeper ? Car has 116k kilometers on clock
Need your help please

Just wanted to let you all know, that replacing sensor (used Bosch) did the trick, no check engine light since than "knock on wood" got the car remaped in the mean time too. Hope it helps someone if facing the same problem.

Hi @aljaz97, I had the same error code on my Audi A4 2.0TDI 100kw and the engine light is not displaying. How did you solve the problem?
