It needs to be tested to see how many modules are shorted. When voltage and ground are reversed, it will normally short the modules, and they will have to be repaired/replaced and reprogrammed for it to perform properly.

Thank you ill get that done.

Good luck, I have repaired many vehicles that had been reversed, and hopefully yours is older with less issues. Had a '07 Cadillac once and replaced 8 modules with 21hrs of labor.

Oh Crap that's not a cheap fix.Im hoping its not going to be to expensive.

Get an estimate first, and even more then one. Not a fly by night place with a cheaper estimate, then hit you for extras.

Very true.Its hard to trust mechanics these days they could tell people anything and without proof it's hard to trust them.Im in New Zealand and the BMW specs here are very good but hugely expensive.It may end up cheaper to wreck my baby or wait ten years until its parts become cheaper.

That's good realization, never know but I bet you'll make the right decision. Happy Trails from the Lone Star State.
