Not unusual for a C5.
The dealer should have been aware but if you follow this procedure then all should be well again.

Dealer fail.....they should know better

They should but often don't.

"Dealers"...after my discovery on my under-tray I will not bother with stamps in the book as it is a sign of Bad Service.

Nothing good, didn t work.All this is quite stupid.Citroen must deal with this kind of issues.The electrician is persuaded that the difference in voltage is the origin of it.I feel like an ass.Incompetent designers .where they find them.......hik
