Hi Bimmer,
I've been driving e90 N46 engine over 6mth. Everything was fine back time, done with oil change, tyre, balancing & hoses. Recently facing a few issues.
1. Suspension
not confortable as usual, can hear knocking sound from back. Front bump too loud especially on rough road/zebra line. Done with service absorber but the prob still there. What it could be & where should I start with?
2. Stalling
normally happen while waiting at traffic light or parking. Also noticed rpm going bit rough if engine turn hot.. morning time no issue. I've done diagnosed last week, valvetronic motor, o2 sensor up & down listed on the menu. What actually could be the other possible causes? The workshop about to charge nearly 2k plus labour.
Much appriciated, thanks.
Cheers guys & stay safe.
