I have n55 engine. Is ibs causing lin problem and then messes up water pump or water pump causing ling problem and messes up
ibs? Please check attached picture.



I cleared errors. Removed ibs, drove 10 miles problem not came back. Connected ibs back, drove again 20 miles, no errors.

I tested car with ista because water pump was turning on itself after turning off engine.

P.s.
I did bleed from ista. Water pump speed was 30-200. Ista gave these numbers.

No experience?

I thought you were talking about IBS and water problems in regards to the bowel and the bladder problems. I could have helped you there. Can't help you with your car issue though.

How old is the water pump? Considering it's N55 and if it's older than 50kmiles I'd replace it just to be on the safe side.
