Multiple fault warnings
 

Hi this is my first post
Hello to everyone
I was driving home on the motorway this evening after 20 minutes or so a warning about the passenger air bag flashed up "urgent service required "
A moment later the Traction control was disabled I opened my car & I couldn't reset it
The the speedometer froze up on zero briefly started up again then went back to zero
The aircon shut off & wouldn't restart then the indication failed
I got home & tried to switch off the engine but it just kept running after two or three pushes of the off switch it stopped then I got a low oil pressure ⚠️ do not start the engine
I finally locked the car up went back later & everything is now normal ?
Has anyone had this problem
The car is a 14 plate T2 35000 MLS

With multiple issues like that the first thing I would suspect is low battery voltage. Check it.

I have had multiple warnings on one occasion. Eight different systems claimed to have failed and there were numerous beeps.

Fortunately I was close to home and I called Volvo Assist; they attended, attached a laptop to find no faults.

Conclusion was that it was a power glitch and it has not recurred.

Connector behind carpet next to accelerator pedal in bottom of A pillar

Pull carpet back and unplug and plug back in a few times,

will sort for a while but needs the 4 network pins replacing with gold ones instead of tin

can high issues various plugs around car 20 trminals need replacing

So this is a known fault? Which V40 models does it affect?

Will affect all of them at some point in there lives,

A lot depends how often you get in with wet feet and you feet positioning against carpet

as above tbh i thought this issue was cured but just seen it on 16my so obviously not new terminals fixed it

regards

How much to fix? Presumably replacing the connector by the accelerator pedal is enough to resolve the issue?

1 pound per terminal if it was me id change the lot 20 in total
