325i N53 08 rough idle on cold start
On a cold start my 325i N53 has a rough idle
After running for a while and it gets up to temperature it runs a bit smoother. I've taken it to a mechanic, then a BMW specialist but I would like a few more opinions It's thrown up all sorts of codes: P0172 - System too rich Bank 1 P0174 - System too lean bank 1 After taking it to the BMW specialist its given codes 2A2C - Mixture control 2 29E1 - Mixture control 2 Then on the way home from the specialist, it gives codes P0302 - Cylinder 2 Misfire detected P0305 - Cylinder 5 Misfire detected P0300 - Random/Multiple Cylinder Misfire detected These codes all disappear as soon as the engine is up to temperature or on a restart a few hours later Between the specialist and mechanic they've checked: Coils Injectors Spark Plugs Smoke test for Air leaks The specialist has suggested its a fault to do with the rocker cover but I was wondering if there is anything else possibly causing issues Thanks |
