Electronic and surging issues

Post by kaydenjoel83 »

Hey everyone! Looking for some advice with my newly acquired 2008 C4 Exclusive 2.0 HDi 103k miles full auto

I have been sussing her out for a couple of weeks now and I think I may have noticed a theme with some of the issues: perhaps some fuse box relay problem?
Rear wiper only strokes 5 times and then stops wherever it likes, both switching on and off. Doesn't intermit.
Both front fogs don't work even after having new bulbs.
Headlight washers have a relay earth fault on ODBII code check.
Drivers window works intermittently.
Radiator fan on continuously from start.

I've not found any wet/damp around the fuse box so I'm not really sure what else I should be doing. If it is a fuse box, how do I know which one I need to source and can it be switched straight out or does it need coding? VIN is VF7**************[VIN obfuscated, can be read by forum staff]

Car also has a gentle acceleration surge issue at around 2k revs, noticeable when cruising at this RPM but not enough to affect rev counter... almost like a pulsing, but I'm not sure this is connected to the electronic craziness.

Grateful for any advice here guys [-o< Many thanks

Try a BSI reset first:

If you have any specific fault codes, pop them up here.

Failing that, see my post here for details you need:

We do ask for a membership upgrade for parts info unless you can find what you need from searching the forum (as we are also charged for this info), but as I have already put this info up, here is a pointer:
