Hi, I've heard that you must not jump start a r129, or else you will blow up the roof ecu! Question is, I always have a charged battery in the garage, could I use that? am I correct in understanding when they say"don't jump start a R129" they mean off of another car?
Thanks in advance

You could connect up the spare battery if it is fully charged via the jump leads if you follow the connection and disconnection instruction in the link above.

When you connect and disconnect the jump lead clamps, don’t do it in a loose fashion, rather do it in a clean quick connection so as to avoid sparking at the battery terminal.

I had an AA guy start my 129 with a battery pack and there was no problem.
