Hi,I have been reading about some 2.0HDI Picassos suffering from terminals on the ECU corroding away.I would like to unplug my ECU to check mine for corrosion.Is it ok to unplug the ECU or is this a no no as it may upset the set up of things.Or are there any things I need to be aware of?? Any info would be great please.Many Thanks Andrew...

Everything off, bonnet open; wait 25 minutes first.
Little risk in just doing it immediately.

Hi Screwloose,thanks for your message,can I just recap on your last message? Do you mean switch evrything off,open the bonett,then wait for 25 minutes and then disconnect the ECU and check everything is ok.Would it be ok to do it after it has sat all night,then uplug it without starting it,or should I wait 25 minutes after closing the drivers door after pulling the bonett catch.It looks quite involved to actually get at the plug,I may be wrong though.Thanks again,Andrew...

Any electrical movement wakes the BSI. So, ideally, get access; let the BSI go to sleep and then unplug.
Not a big worry even if you don't. Never had a problem hot-swapping.

Thankyou.Can I just ask was the acronym BSI stands for? Andrew...

It's French - but "Built-in Systems Interface" is one translation.
