SL 129 dashboard PCB fault

[Pipemaster]

A while ago (feb / March) I posted about my light being out on my fuel guage and that I had been told that the PCB would need to be replaced by the dealer. I have not replaced it as yet.
I then (last weekend) had a brief and intermittent problem with the airbag warning light and SRS, the indicators and wipers becoming inoperative which I posted on. I now notice that the low fuel warning light built into the lower quartile of the the fuel guage does not illuminate if I have the side / headlights on, but does illuminate if the lights are off.
My question is: could this all be connected to the sale PCB fault and if so I think it's time to chnage / repair it therefore does anyone have recommendations.
I use the car daily and cannot be without it for any length of time. Is there a exhange service that anyone knows about?

Thanks in advance
Steve

sounds like your ign switch re the wipers/srs, and just a poor earth on pcb. some pcb's can be repaired.

As Star with the wipers, the switch is a common problem on the 129.

Any TV engineer could fix the PCB, the copper track is open circuit near the two bulbs and it needs bridging with a strand of wire, with care so that the bulbs will go back in.

I wished now that I had taken a photo of the last one

Pardon my ignorance but change the ignition switch is not the same as changing the key barrel is it? :neutral:

correct, the switch sits behind the barrel.

Thanks Star.. as a mercedes speicalist you wouldn't know how much they are would you?

not off the top of my head, but about £30-£40.

I think it is A1295450204 and it costs around £65

That was for my chassis number, 1990 500SL
