Hi, I just picked up my E53 and first ever BMW. It is a Silver 03 4.4 with 112k on it. I have done quite a bit of reading but I still have a few questions.

First of all, this thing has really touchy throttle response. Is this normal? I looked and didn't see any kind of drive by wire module on it.

Second, my clock, BC, and phone buttons don't work on the MID. Occasionally if it hit them the screen will blank out on the lower portion but comes back with a restart. I have read that this can be due to the instrument cluster being swapped out but everything looks to be original. Is there anything else I can check?

Other than that it is a really clean vehicle and a ton of fun to drive!

Thanks for any help!
