Hi all I have a 2008 Citroen PIcasso C4. Woke up yesterday and started it, the onboard display suddenly tells me that ABS, handbrake, airbags, suspension & gearbox are all faulty. Obviously cant be mechanical as everything woked fine the day before, I've browsed forums on this and from other postings I think that the error is with the cars ECU / computer. Apparently a common thing that water finds it's way onto the computers connector / plugs and corrodes this. I am not in a position to fork out hundreds of pounds to get this fixed so plan to fix it myself. Problem I have is that I dont know where to find the damn computer and its connectors and what to do if I do find it. Really hope somebody out there has had a similar issue and will be able to advise. Thanks very much
