2003 BMW 325 Owner Comments

problem #5

Jan 222011


  • 70,000 miles


Car ran perfectly, then I turned off, then I restarted 5 seconds later to reposition in garage. Engine then revving from 800 to 1200 RPM rhythmically, approx once per second, eml light on, brake light on, service engine light on, very hard to stop car, had anyone been close I would have hit them. Engine revving continued for 2 days, then went away on own. I then took off airbox to inspect maf, filter. Codes on 3rd day: P1632 throttle, pending: P0102, iats. There have been other incidents over the years of restarting engine to have extremely rough idle, also cleared on its own, but never surging like this.

325 6-cyl

  • Manual transmission
  • 1,000 miles
Erratic idle... when stopped at a stop light, car in neutral, the rpms rev in spikes from 500 to 1500, up and down, up and down. The car never resets to a constant idle. Car has been in shop 8 - 9 times over 18 days total. No solution. Tech told me BMW know of problem but has no plans to find a fix.
