have you tried turning it off and on again?

how about rice? have you put it in rice?

maybe pull the connector out and blow in it realll good… side to side… blow and clean it out.

if that dont fix it… yeah you fried some electrical component by having the hv connected when those who knew better said to not to. im sure itll cost a fortune being a bmw and 10 years old to replace whatever circuit board got cooked.

but the only way to actually know… take it to the dealer.

cash 4 clunkers is back!? man i been waiting for this… i got a bunch of old ones saved up this time
