Question about BMW 335
Someone got a jump off me the other day and convinced me that it is ok to us the positive terminal only for my vehicle to power his (the one that is in the engine section not near the battery). A few days later dash warnings for ABS and Steering and Check engine began flashing erratically and then the car died (also the radio goes off). It has happened the last few times I have attempted to drive the car. It makes the car stall. I have checked all the connections, the fuses, wires for exposed parts, and I have disconnected the battery for an hour only to find now it doesn't even crank only all the lights continue to work.
Some BMW's have a chip in the battery cable that can go kaput. I've never had to replace one but I'm told they cost around $800 coconuts. When we see jumper cables in BMW's we tell the owner to never use them. These cars are like little rolling space shuttles. The very least you will probably need is a computer relearn/flash/coding/regeristering. Even when changing battries use a BMW batt white case or black which ever came out, Then get it "registered" or you're car'll be confused. I wouldn't ever recommend aftermarket electronics either unless the installer is trained to install units in BMW's.
