320 I 1993 Auto Coupe :problem.....

[theeflash1]

BMW 320i E36 AUTO (1993) Ovefuelling problem after I accidentally put too much engine oil in car.

The wiring diagram states that the Relay is switched from the ECU. Is the ECU in this car a SRAIGHT PLUG IN or CODED(Dealership Job)..?

Thanks..

• EH? i am well confused! over filling an engine with engine oil would not make it run rich,
  

what are the symptons here?excessive smoke? burning of fuel?

we can sort it

I would of said a ECU reset, only because i don't know why it's overfuelling due to too much oil.

Have much did u overfill it with oil?

As long as u ddnt experience 'piston slap' u may hopefully of gotten away with it?

Over filling can cause all sorts to fail.. Mostly gaskets..I can tell u this from experience lol

Is it overheating at all? Exhaust popping Or smoking as ian suggested?

Have a quick check of the spark plugs..

With regards to the overfuelling this will probably be the fuel to air mixture which will cause it to run rich.. Average i think is about 14.7 air to 1 fuel.

ECU's not doing its job right or could even be a dodgy MAF..not allowing enough air in.

Im thinking out loud here so Ill do a bit of research for you because im slightly confused =p

It could be a lambda,a temp sensor all manner of things

The ecu is coded to the ews which in turn coded to the key,however I will be nice to gav for one week if the ecu needs replacing
