I am planning to rewire my trailer and change from filament bulbs to LEDs. My 2012 Elegance works fine with the trailer as it is, but would changing to LEDs cause any problems with the car recognising / reacting to the trailer lights any differently? Thanks Simon

Thanks Frenchtone. I have replaced the switch with a genuine part from the dealer, (£85), but it made no difference.

My 2012 Yeti 2.0 TDi 170 Elegance has a lighting problem. As soon as you turn the ignition on, the headlights and tail lights come on. The light switch makes no difference, whatever position you put it in, (or even if you remove it). This means that the foglights cannot be used. It looks like the Body Control Module on the inner bulkhead that the switch connects to has gone into safety mode. Does anyone in South / South West / Mid Wales have or know an independent with VCDS who could test the module for me and code a second hand replacement to the car? Thanks Simon

Gumdrop - headlights come in with dipped beam. Stalk allows switching from dip to main, flashing main, as usual Frenchtone - thanks for the suggestion, will give it a try Austin 7 - both about the same price I took the switch out and switched on the ignition; dipped headlights and tail lights came on. Implies a broken circuit in the switch, (as per Frenchtone), as the switch is not interrupting the fed to turn them off when switched to off?

2012 170 TDi Elegance As soon as I switch the ignition on, the headlights and tail lights come on. The headlight switch position makes no difference, (Off, Auto, Sidelights, Headlights), nor do the fog lights work, (no tell-tale on the dash and lights do not come on). Engine on or off makes no difference. Dip / main selection via the stalk works as normal. I am thinking that the switch is faulty and the car is defaulting to a safe mode. Is there such a thing? However, the car has a panoramic sun roof which has had a minor leak in the past, (but not now, as far as I can tell), so could something else be at fault? The dealer wants £100 to run diagnostics, so if anyone can offer advice, (knowledge, please, not just guesses), I would be grateful. Thanks Simon

Hi, I have a 2012 170 CR TDi, (CFJA engine). Does anyone know the size of the sump plug washer? I want to replace it when I do an oil change but the likes of ECP don't show which size fits which vehicle. Thanks
