Just bought my first X5. New challenge to make it run:)

[CapeX5]

I have a feeling that I know how this is going to go end up. I will try to be nice. You have a plethora of talented people here who will attempt to guide you-but only to a certain extent. Many of us have been messing with these for a long time and are willing to share our experience. But, if you just want to go about this like fixing a 1978 camaro, I am out. You need specific tools for these cars, i.e. software/scanners. These are not expensive. And I will warn you, just throwing parts at this will empty your wallet quickly and you will not have accomplished anything. Enough said-carry on....

I accidentally damaged my MAF sensor and now my transmission is jerky and I get code P0102. Same symptoms as here

Well at least I know the MAF sensor was working so I'll replace it and this will be easy to fix.

I found another user who had the trunk lid open when turning off headlights.

Looks like a problem with the switch.

I'll replace the broken hose tomorrow. When the car was running, I put my finger over where the hose connects to the back of the engine and felt some suction. So that hose definitely does something.

Tried driving after cleaning throttle body etc. but still the same issue.
