B0020 B1825

[508c5]

Hello,

Citroen C4 Picasso (5d, LHD) 2017, 1.6 Petrol, 165bhp

Got 2 fault codes which i can't figure out...i'd appreciate your advice (LAUNCH report, not DIAGBOX).

B0020 - fault on the line of the front left lateral airbag - short circuit to earth. This is the read. I should mention that while turning left (i think) the airbag light comes on and blinks (+ "blip" sound) a couple of times. I am guessing it has something to do with the airbag connector under the driver's seat but can't figure out what exactly is this "short circuit".

B1825 - oil level information fault. This is the read. There was no warning light or massage on the dash re oil level or anything in this regard and as far as i know a faulty oil gage sensor throws a different code.

got other faults as well but they don't bother me that much.

Thank you in advance.

I'll need the VIN for this vehicle to see if I have anything to add. It is masked on the report.

Hi,

I have this on my C4 Grand Picasso mk2:

B0020 - fault on the line of the front left lateral airbag

Can someone provide diagrams or pictures so I know which connectors under the seat to inspect? Or other ideas to get rid of the issue?

My MOT failed because of this so got 9 days now to solve it.

Much appreciated
