It's a 1994, 300tdi Auto, with twin air bags, MA648***
The SRS light flashes for a few minutes, then settles to steady on. The battery had gone a bit flat after a few weeks non-use, I'd started it with a magic yellow box, then charged the battery overnight with a cheap old charger, showing no more than a couple of amps or so.
I gather from googling that it needs it will need connecting to "test book" to reset it, but I don't really understand the relationship between "testbook", "T4", and another clever box whose name I've forgotten. I'm not even very clear whether we're talking about dedicated hardware or software that is run on a laptop
Would someone please explain, as to a simple soul, what options are open to me to sort this out? I'd prefer to avoid a) going to a dealer with posh showrooms; b) taking the bulb out; or c) putting a bit of black tape over the bulb. I'm quite happy to download software and to buy mysterious cables or adapters if necessary - if I knew what I needed.
I'm between Derby and Nottingham, if anyone can recommend a non-Hunters solution.
