Hi Guys,
New to this site so forgive me if this has been covered, I would appreciate a point in the right direction if it has been covered.
320d e46. 2005. 129000 miles.
Recently my car has been acting oddly. The engine management light came on and the mechanic i had out to take a look cleared an oxygen sensor code and told me to run some diesel magic through the tank. This should do the trick.
Didn't have a serious problem until a few weeks ago. The car now randomly has losses of power, sometimes its fine and i have full power, then i could change gear from second to third and its like the car has gone into limp mode. Then a few corners and a few gears changes later it has some power back but not all of it. I also sometimes get plumes of light smoke, light blue smoke but never dark smoke. I purchased a code reader and saw multiple codes. I cleared them Which seems to get the car back to normal for 30 seconds ish and they obviously keep coming back.
Codes:
3f25 - charge-air tube monitoring
4212 glow plug cylinder 1, activation
4222 glow plug cylinder 2, activation
4232 glow plug cylinder 3, activation
4242 glow plug cylinder 4, activation
3FF0 Air-mass flow sensor
3FF1 Air-mass flow sensor
41E7 Oxygen sensor, signal, pump current
4B10 Smooth running controller
So doing some reading and general research I decided to replace the MAF sensor which didn't make the slightest bit of difference. I took it to my local garage and explained. They took all day looking at it and eventually asked me to come collect it because they couldn't figure out what was wrong with it.
I am currently waiting on an automotive electrician but that isn't booked in until the end of Sept.
I was wondering if anyone had experienced/seen this before and has any advice or knowhow on what to do to remedy the car.
Thanks in advanced guys
