Service at dealer w/ Catless DPs?

[Revnato]

Thinking about bringing my car into a dealer to have them see if they can find out why I'm getting a reduced power warning during hard acceleration.

However, my car has catless downpipes and a tune. Will a BMW dealer even look at my car if it has catless downpipes?

Yes, but most would say it depends on your relationship with the SA. I was upfront with mine and told him that I was catless and tuned. He has worked on the cars bunch of times since for injectors, ignition coils, etc. Not everyone will be the same. Have you been to the dealer before?

I have a similar experience. My SA knows my car is modified. I have owned several modded BMWs over the years and he knows that if a part fails because of mods then I don't expect BMW to warranty it. However, if it breaks unrelated to mods he doesn't give me any hassle.

Oh nice thanks for sharing! I'll definitely be sure to have them check the throttle bodies. I'm taking it to EAS in Anaheim tomorrow. They originally replaced all the ignition coils & spark plugs, but that didn't fix it. I'm really hoping they can figure it out this time
