Welding a multiplexed car....
Not impressed....spotted some peeling paint /dark spot on the NS sill of the Picasso (this is a 2003 car, just 7 years old). Was thinking it would just be peeling a bit as my old Xantia did, but no, it's rusted through A quick poke made a small hole, but thumb pressure reveals an area about 6" round that is distinctly crusty. So patch is going to be needed I guess - won't pass an MOT like that! No damage apparent, and it appears to be rusting from the inside out. To hide it properly will be expensive -it's a painted sill, not an undersealed one. So, probably just DIY, grind the welds flat, and blow it over with a rattle can Then chop it in....
Anyway, any experience of MIGing multilplexed cars? Just drop the battery off, following the normal procedure, and away you go?

Sounds as if there might be a bunged up drain hole somewhere?
Ive had this before on a car, the drain was bunged (with the missing cap from the washer bottle top) and over time it caused the sill to rot out.
Ive never seen a rusty Picasso, cant imagine its normal.
No idea about welding a plexed car though, i asume its just as normal.

Hi Richard, I would suggest not only disconnecting the battery, but also the connector plug to the alternator and all the ECUs as they will all suffer if there is a surge or spike that runs to earth in the car.
I know its a pain, but I always disconnect any sensitive electronic units in a car before commencing any electric welding. It only takes a few milli-amps and the component is toast. A nasty shock then follows when you find out the cost of the replacement parts.

Looks like it should have had an inspection last year at 6 years old, which it certainly didn't. Will be to my account then
Still I managed to re-fix the exhaust heat shield yesterday which has stopped it rattling like a demented cement mixer every time you reversed it
BTW - Citroen are still knocking Xsara Picassos out new - only 2 models available, 1 Derv, 1 petrol. The Derv one (Hdi 90, VTX+ or somthing) has a list price of nearly TWENTY GRAND!!!! Who are they trying to kid?????
