Hello there,

My newly-acquired E30 didn't make it through the Max Power era without war wounds so I've spent the day ripping out aftermarket audio - & came across the below part.

Question is - what is it & what does the currently unconnected plug do?

If box is unplugged car turns over but doesn't start - plugged in it runs fine.... Immobiliser perhaps?

Answers on a postcard....

Quick 10 points earned there, Sweep.

Follow up question - where does the loose connector plug into? Can't see anywhere on this box - only room for green plug.

Yeah - speakers have been chavved so originals are on the parts list.

All doors lock at least! Productive day.

Cheers for the help

Yep, That's the relay module for the OBC.

If you set a code in the OBC code mode then it will immobilize the car.

Probably a good idea to check out how to remove it as they are a known source of non starting even when the right code is put in.

Anyone any thoughts on how to 'lose' the code function on the OBC so I can chuck this box in the bin before it causes me problems....?

Put the original 'link plug' back into the immobiliser socket above the glove box.
