Hey all,

Car: Z4 35IS with 39k ish miles
MHD Stage 1+ 93 Oct

While driving tonight when I tried to put my foot down the check engine light appeared, the car appeared to heavily judder and almost felt like it was in limp mode. I had monitoring running at the time and managed to capture a log of this.

Could anyone please advise?

The active error code is the below:
2900 - DME Combustion Misfire Cylinder 4

Missfire on cylinder 4. Could be your coil pack or injector. I would try swapping coils around and see if the misfire moved to the other cylinder if it does. Means the coil pack is bad.

I have opted for a full set of coils and sparks since the car has been remapped. Hopefully this resolves the issue. Will report back

Thanks!
