AWR-fix: 20 pin under hood OBD tweak
If you have a 1999-2000.5 model X5, you will have the old school 20 pin round obd port under the hood. With this system you will ALSO have a 16 pin port under the dash which has only the minimum connections to the engine to use for emissions. I read somewhere sometime it was possible to jumper a few pins in the 20 pin port to connect the important computer lines to the under dash port so you can use a scanner from inside the car to perform maintenance vs under the hood. (It's far easier to measure real-time O2 value etc from behind the steering wheel than under the dash!) So here's exactly where to wrap a bit of 24ga solid wire to perform the fix: Incredibly helpful that the three pins that need to be jumped actually have a pin in the cap. I wrapped each about 4 times and snugged the winding very tight. No need to solder. ∞ nicer to access all the modules from in the cab like I do with my car now! What the frig guys why did they do that in the first place?

I thought you did this years ago, Andrew!
Good to know it works - like you, I've read about it before but never had any real confirmation of the results.

I had the goofy adapter dongle. I never figured out that the magic pins already existed inside the cap to make it happen. It's been very frustrating

Bump: I had a typo in the title made impossible to find with a search. Apparently the index isn't updated immediately.
This trick is a must for people with pre 01.
