Not crazy at all, happens all the time. You need a fault code read.

I have exactly same problem. I have a Sharan 1.9tdi 1997.

Is there a way to temporarily disconnect the red airbag light on the dashboard so I can get my car through its NCT (Irish MOT).

I know someone will reply about the safety issues, and I appreciate their concern if I have a crash but just want to get it through NCT and then get it checked out properly.

You can clear it with vcds.

You can't just clear a code. If you have a fault the light will come back on. You have to fix the fault. You can't just disconnect the bulb (unless the MOT tester is stupid). They are supposed to watch it come on and then go off. It won't do that if it is disconnected.

I cleared the fault yesterday and it stayed off all day. However it was back when I started the car this morning. So you are correct.

I'm happy to clear the fault just to get my MOT certificate. I then can swap airbag modules etc from my spares vehicle until the faults are cleared.

You can't just disconnect the bulb (unless the MOT tester is stupid). They are supposed to watch it come on and then go off. It won't do that if it is disconnected.

You are correct. I didn't fully understand how the system worked until yesterday. I still have an issue with "an optional extra" as this system was back in 1998 being an MOT failure!

A local mechanic had a computer attached and came up with the following codes -

00588 Airbag Igniter driver side N95 - sporadic: Value of resistance too great.

00532 supply voltage - sporadic: Signal too low

Sounds like a dirty connection. With UK MOT, if something is fitted they can test it. So when old cars have added seatbelts, the seat belts get included for test, even though the car may have been delivered without them originally.

Air bags are not part of the MOT test, yet!

airbags never have been a testable item,but as crasher states ...yet...it is coming along with towbars,engine check lamp and many more items..............

11-03-2011, 10:21 AM
many more items..............

And to see if nasty illegal HID headlights are fitted, yeahhhh!!! :D:D:D:arms::banana::biggthump:fest30:

Come on ursu A6, at least give us a little more of a clue as to what the vehicle is than it possibly being an A6, we ainít ******* psychic after all!

463A is VAG code 17978 (P1570) - Engine Start Blocked by Immobilizer

024C is VAG code 00588 - Airbag Igniter; Driver Side (N95)

but is defined as resistance too high, low or short to positive or ground

463a engine control unit disabled
024c driver side front airbag igniter circuit 1 highley resistive
i got told today that the fault is only at the driver seat(under)there is plug wich is dirty....dusty........
tomorow i will take the plugs of.........clean them and put them back on............and maybe i m lucky

thanks very much

What year is your A6? If you keep giving us HEX codes, no one will understand other than those able to covert a hex code to a VAG code. 024C is VAG code 00588 which is the steering wheel air bag N95, the seat air bag on the drivers side is N199 so if you start messing around with the connector under the seat you may end up with another code. The official Audi procedure for code 00588 is

00588 Igniter for airbag, driver's side -N95 resistance value too high

1) Open circuit. Fault find according to current flow diagram
2) Coil spring defective. Test coil spring
3) Driver airbag unit defective. Replace airbag unit, driver's side
4) Control unit for airbag -J234 defective. Replace control unit for airbag -J234

Fault code 17978 (hex 463A) is

17978 (P1570) Engine control unit blocked.

Engine starts and immediately cuts out again

1) Attempted manipulation- Engine control unit replaced and not matched to immobilizer. Match immobilizer to engine electronics control unit
2) Short circuit in communication wire. Check wiring according to current flow diagram.
3) Immobilizer control unit defective. Check electronic immobilizer

The 17978 code should not be taken too seriously, especially without a fault cod read of the immobiliser so I would just ignore it.
