R53 Rear Distribution Box and Exploder Valve


First of all apologies for making my 1st post a question!

I have a '54 plate Mini cooper S (R53), which has had a massive and long term water leak into the boot, which I didn't know about until a complete loss of electrics!!

Basically it looks as if water has been sitting in my boot for years, as it had almost fully corroded the rear distribution box housing the 250A fuse. I have rebuilt the distribution box, so that is all sorted.

My problem now is that my airbag light is on, because the small connector block attached to the distribution box has also corroded, so the 2 small wires from the SRS exploder valve are not attached to anything.

Can I just connect the 2 wires together, bypassing the corroded connector, or does the connector serve some kind of purpose? Resistance to drop the voltage and remove the airbag light maybe?

I'm in a bit of a catch 22, because I can't take it to be diagnosed, without connecting everything back up, but I don't want to spend the earth connecting everything back up to find that it wasn't that in the 1st place.

Thanks in advance.

Hi ya

For your airbag system to work you need to repair the cable or replace it and make shore the link is ok.
The link is there for cutting power from the battery in case of a crash. it cuts the link just after the airbags deploy

There is a repair cable or a complete battery cable. I am not shore what part you really need with out looking but this link may help you

RealOEM.com * BMW R53 Cooper S Battery lead/distribution box, rear

You could get one from a breaker there are a few good ones around on the net that specialise in mini's

If the battery cable is that corroded I would replace the assy as it will carry on corroding until you start to get electrical problem may be a fire.

Hope this help
