Hi I had the airbag light come on then later the airbag inflated and the car cut out. having got it towed to garage and found the alternator and battery needed replacement the garage then can't get any ignition light ( Ithink) and soo it won't start. They suggest it is an ECU but on reading other bits here I am not sure if it is an airbag thing or something else and if I get a 2nd hnd ecu will it work or still have to get it towed to Skoda garage and more money. I am now not sure if I should just scrap it - any help please? thanks

you'll need a new airbag control unit, iirc once the crash signal has occured (airbag deployed) you can't reset them

I wonder if the electronics have been fried? (I am assuming the garage has checked the fuses already).

If the ECU needs swapping it will probably need to be coded by Skoda. I'm not sure if there's a way of avoiding this.

An airbag control unit should need no coding though and be a straight swap - but you need the car itself running first.

Please let us know the engine type and year as that may help (1.3, 1.3mpi, 1.6 etc).

Here's an ECU for a 1.6 that looks like it will go cheapish Skoda Felicia E.C.U. on eBay, also, Skoda, Car Parts, Cars, Parts Vehicles (end time 23-Oct-08 20:59:17 BST) (will ONLY work on 1.6 models though.)

Crikey, Della! Were you just driving along when the airbag inflated? :eek:

it sounds like the faulty alternator has fried more than the airbag controller, you may need a whole new engine management ecu or possibly worse. Sadly this is what happens when a faulty voltage regulator goes unchecked and the owner continues to drive. The excess voltage in the cars electrics kills everything, battery, ecu and so on.

An idea about Airbag prices

What engine did your Felicia have?

Have they checked the fuse for the engine ECU?

mannyo - I was one of these people! I recently had my alternator replaced. It had already knackered my battery. The car now runs, but you say that the excess voltage kills everything - might there be problems that I've not noticed?

I think it's probably the failed control box led to the alternator cooking lots of electronnicy bits.

But still, it might just be that the airbag controller told the fuel cutout to cut out.
