Check Engine After Installing Donaldson Blackwing!!!!

I installed A Donaldson Blackwing on my stock 98 A4 with 3.15s two days ago. I now am getting an engine light, owners manual says the light means there is an issue with the computer. The car sometimes does not down shift when I floor it at 40 mph and feels like it is not as responsive. Anyone else have this problem????

What's the PCM error codes ?

You might have an airleak somewhere by the MAF, check for something loose or not being fitted correctly.

Not knowing the codes, it could be something not having anything to do with swapping airfilters.

Installed the same unit on my similiarily equipped "99" and did/have not experienced any problems like you described!! :confused:

I think John probably diagnosed your problem pretty accurately though... .... :yesnod: Hopefully he's right and the problem will go away after you "re-tighten" everything. :D :D

Good luck....

Make sure that you do not have a kink or loose fitting with the small breather hose that fits on the side. This will cause your PCM to throw codes...

This may sound silly/obvious but make sure you plugged the MAF and IAT back in and that the plugs are seated properly.

Like everyone said check all your connections. Make sure everything is seated in position.

Re: Check Engine After Installing Donaldson Blackwing!!!! (MC98)

Thanks fellows, some of the clamps were not as tight as they should have been so I tightened all of them. Should I drive the car and see if the check engine light goes out or should I disconnect the battery to clear the code and then see if I get another check engine?
