Both lamps blew at the same time? It happens.
Lidl stock +100% brighter H7s every now and then.Will certainly check the bulbs.... Was running osram night breakers - would prefer not to have to buy two of these again 🤣
Alas it's Xenons....Lidl stock +100% brighter H7s every now and then.
Priced at €6.99 a pair down south.
They're decent enough IMO
Is the system different to the 156 then? I remember with both of mine I could run front fogs with just sidelights on, it was only the rear fog light that would only work with headlights on.The light switch commands the lights on, the stalk controls dip or main. For dipped beam, the BCM drives the relay R1 in the aux relay box under the bonnet, this feeds a fuse for each headlight. For main beam, the stalk switch directly drives relay R4 in the aux really box which in turn feeds a fuse for each main beam.
If you can switch on the front fogs, then the BCM is getting a 'headlight on' signal I think, so that suggests either the relay R1, both fuses, both bulbs or a common wiring fault. Given the other symptoms, a common wiring fault might be to blame.
You could well be right about that, hence my “I think” caveat!Is the system different to the 156 then? I remember with both of mine I could run front fogs with just sidelights on, it was only the rear fog light that would only work with headlights on.
New yuasa battery put on....Could it be one or two burned fuses or a bad battery?
Yeah the 30A fuse cooked as I watched several years ago... Smoke was a pretty clear indicator....The heater fan is controlled by the climate module so no direct connection with the BCM.
A common issue with the heater fan is the dedicated 30A (I think) fuse that feeds it - the fuse holder tends to cook over the years.
I suspect this will need some thorough and careful diagnostic testing….and that’s going to be expensive unless you can DIY. Firing the parts canon isn’t likely to sort it I suspect.
Just to update this.... Replaced the Body Control Module and normal headlight function has been restored.....Yeah the 30A fuse cooked as I watched several years ago... Smoke was a pretty clear indicator....
The bushes on the motor have also been suggested..... So will aim to get the aircon degassed etc and take it out to check
