My EMC died in my Oldish 2.5 BMW. 1997 model with low mileage.

 

Gutted, but a buddy of mine who works for BMW had a new one sent down from one of their other workshops. This one works, but the engine runs as rough as rats. We had the new unit back in the workshop and it checks out o.k. The old unit was remapped after I had a decat pipe fitted and a K&N induction kit fitted.

 

Do we think, if I put the Cat back on and replaced the original air filter, it will make any difference ??

 

I am really fed up as this 'mishap' has cost me a run down to the Oxford meet :-x Of course it has to be over a weekend when this happens !!!

 

Many thanks,

 

Lex.

Without a doubt Lex........yes. The new one will be looking for the cat feedback so will run as rough as .......well you think of the name!!

 

On your car it needs to be coded into the other systems on the car for a start let alone the mods you have made.

 

I'd suggest putting the old one back and whilst cranking the engine give the unit a bash. If it fires then it indicates a dry joint on the unit PCB. Some of the earlier ones were known for this.
