Thumbs up

I have just fitted a K&N 57i induction kit to my 98 523.

When driving, all of a sudden she will start to pop, cough and fart and sometimes stall, then, may run fine for a while before doinig the same again.

Everything is connected correctly and I have reset the ecu by removing the negative battery lead for half an hour.

Is a beamer one of those cars where you have to remove a fuse to the ecu to reset it????

Any help greatly appreciated.

Well, K&N is an oiled filter...my educated guess would be that the oil from the filter was carried into your air system and has coated some essential sensors, like the Hot Film Air Mass Sensor (HFM) and the ECM is unable to sense the amount of air passing by it...which in turn the ECM is sending the improper amount of fuel to the cylinders...unfortunatly there is no real good way to clean an HFM that I can think of off the top of my head.

What I would do is remove the filter and spray some carb cleaner in there while the engine is running, but not so much that it will stall.... just slight bursts and mists.

Make sure the filter isnt over oiled and reinstall....


Do this only if your filter does in fact have excessive oil.

DO NOT SPRAY CARB CLEANER ON A HFM!!!! I can NOT stress this point enough....a HFM operates at 1800*F, so unless you want to burn your car to the ground keep all cleaners away from it...you could try to remove the HFM and after letting it cool clean it with a cotton swab and rubbing alcohol...let the alcohol evaporate before re-installing it on the vehicle!!!!

Thanks for the suggestions people.

All of a sudden she has started to run much better - doesn't stall or shudder too bad and most of the time runs pretty sweet, however, there is sometimes still a little shudder every now and then.

Engine sound around 4-5500 revs is great but thankfully below this you can hardly sense a change.
