2002 B5.5 G180 Crash Sensor Someone Shoot me now

[GavMc P11GT]

Hi folks

I'm at a dead end with this one I've had a g180 fault on my passat initially after researching on the forums I thought dodgy sensor so got 3 from the scrap yard tried all three and the fault still remains. I've tried to clear it each time using the little computer and each time on the 3 sensors I got from the breakers the light never go's out

Back to the origional sensor

When I clear the fault with the original sensor fitted the light go's out for a few mins then comes back on!

Following more forum searches I pulled the carpets up center consul out and checked the harness found two rusty eart wires and a dodgy earth joint the dodgy earth joint was in the airbag module loom and the two rust earth points were the convienence module and the airbag harness coming from the main module to the passenger door frame so I sorted all those out soldered all the joints cleaned all the surfaces on the earth points fitted the original sensor again cleared the fault and the light went off put the car back together last night it stopped off

Got up to go to work this morning started the car

Guess what

No

Wait for it

Have you had the seats out? Could it be a dodgy connection into the base of the passenger seat?? May be worth checking the connector is in properly

I have this fault also, not tackled it yet though, first point of call is to pull both seats out and swap the crash sensors around, passenger sensor to the drivers and visa versa, if the fault moves to the drivers side then the crash sensor is at fault, if it stays the fault lies else where either with wiring or the airbag module

Cheers for the replies guys I'm getting 01222 j234 had the seats out the full schebang lol I am right in the sensor on the passenger side floor pan bolted to the cross member next to the rear floor air duct

Yeh that's the crash sensor mate

My mate had the same fault code on his tdi Highline went to main dealers as know one could sort the problem, they ran full checks and said it was a damaged repaired Passat and as the airbags were deployed the fault code cannot be removed, As long as the airbag warning light isn't on it will pass mot.

Hopefully yours is something simple.

Hello,

I've had the same fault myself for months. Only just got it fixed by getting a replacement crash sensor from a donor car off eBay. There are apparently several types of sensor that are in circulation, even though they all look the same and have the same part code on.
For example, mine needed to have 004 at the end, and only a VW dealer could tell by comparing my car to the donor car (by registration). It's possible you've had three incorrect or faulty sensors?

Mine showed signs of corrosion on the metal surfaces and the car was soaking under the carpets when I bought it so assume it had become water damaged at some point. I've also had the soldering wiring adaption on the done prior to replacing the sensor but that did no good. I feel your pain!

[bepe]

That's why it's best to try the other side crash sensor in your car to rule out that its the crash sensor or not!

Cool will try that next then!
