Multivan T5.1 CEL "Engine Fault Workshop"

[BrianJ]

There's a lot of faults there, the simplest thing to do while it is at your house would be to reseat all the fuses and relays, in all fuse boxes including the one under the battery, in case it is caused by a loss of electrical power to some parts, like the relay that controls the vacuum to the turbo. Most of the minor glitches I have had in my kombi have been fixed by reseating the fuses.

I don't guarantee anything because I don't know what the fault is, but this is the easiest thing to try.

Edit: By reseat fuses, I mean to pull each one in turn and press them in again, this will fix any that have a bad electrical connection.
