This problem has been going on for three days now, the car starts on the 2nd-4th try.

The check light comes on for a while, then goes out.

I tried to count the misfires via VAG COM, field 014,015,016 is empty.



readiness



Secondary air is disabled by chip.

Any thoughts?
Could it be the throttle valve?

A couple of days before that, I hit a pothole on the road and I got error 01590 igniter for battery (n253) and airbag light is on.

I fixed it, disconnected the connector on the igniter, re-inserted it, erased the error and everything became normal, I don’t know if this is related.

engine idle speed jumps from 600 to 640.
when I tried to look at group 014 it was already 500-520, after warming up to 70c

I have registered for the service but I will have to wait 2 weeks considering I have a vacation in 2 weeks, it looks like it will take more than a month.

 

Another moment, when the engine is fully warmed up, shows an error - a short circuit of the CAN bus and the blocks are not read.

I don't know if this is related or not.

Any ideas?
