Hello all, thought I would ask here if any of you may have a solution for the problem with my mums car. It's a fabia 2003, and has had very little use, because of this her battery recently died, she had a local mechanic fit a new battery, but the next day it was dead. The mechanic hadn't tightened the earth terminal,  cut to the chase i tightened it and it all seems OK, except the airbag warning light is on ALL the time very very dim, even when engine is off. When the ignition is switched on the airbag light illuminates like normal then goes off, but it stays on very very dim. It's hard to explain, but could the instruments have an issue like a bad earth or solder

Update, I have the car at minute and realised it's not just the airbag light, others on the fash are on constantly, they are very very dim, but are on

Also the horn isn't working, and I don't seem to hear a clicking from the relay, do you think this all could be related 🤔

Almost certainly. I'd start with a deep load battery check and whether or not the charge light activates correctly.

So you think it may be the alternator? I will go check it with my volt meter, the battery light does go out when started like all the rest, but as mentioned some are staying on very very very dimly lit

thanks

I was wondering about alternator control wires, but if the battery light appears on switch on, and goes "out" on engine start it's not them.

The battery test should be free, on the understanding that you buy a new battery from the place that does it if needed.

Just posted a reply on here under your other post.
