Hello all hope all is well in the Bimmer world.
I have a little problem I hope one of you will be able to help me with.
I've got a 318tds touring and I've got a chip off e-bay that should give me 122bhp I've followed all the instructions that came with it, one small problem when I opened the cars ECU there were 2 chips side by side and the instructions don't say which one to change
Any Ideas ?????
