Dipped Beam Issue - Megane Mk2

[Chris_Beer]

Car: Megane Mk2 2008

Issue: Passenger side dipped beam not working - Has an aftermarket, but yet decent H.I.D. kit fitted (Nothing Chinese off eBay!)

Previous Info: Failed MOT on front pads and out of the blue both dipped beams not working. Took the car away assuming they did something wrong with they key card ignition / auto lights, as they were working. Took the car back after doing the front pads, no issues, 12 months MOT.

A couple of days after this, no dipped beam both sides, so there was an problem. I got to the fuses, both were fine, put it all back together, dipped beam was working again?

A month later, the passenger side dipped beam stopped working, so I assumed it was a bulb this time.

Things I have tried:

Another proven working bulb
Another proven working ballast
Checking every single fuse on the board (engine bay) and fitting proven ones
Ditching the whole H.I.D. kit, and fitting original Philips bulbs
Giving the main wiring plugs on the headlight a wobble whilst everything is on
Swapping the headlights left and right to see if the problem follows the headlight. It does not, and both work completely on the drivers side
Disconnecting the battery (Whilst checking all the fuses) and resetting the auto lights function on the stalk, also tried using the lights manually


So, at the stage now where using the car has to be planned, and if it's going to be likely to need the lights on... !

@bloke @STEVE.M @YorkshireKyle ?

Everyone's help on this is really appreciated

Thanks
Chris

connections on the fuse board ok?

There's 2 fuses for headlights on Meganes iirc, one for left and one for right. If they both seem okay have a look at the plug and wiring as they're common to get corrosion on them

Might be worth testing with a multimeter, if you're not getting 12v at the plug then follow the wiring back and clean as necessary mate

All looks very clean in there. Compared to my Clio, it looks brand new!

Can't really get at anything on the Megane one unlike the Clio plugs underneath.

Correct, fuse for each dipped beam. Tested, swapped, replaced, still the same.

The plugs are we talking about the headlight ones or fuse board?

I would say 100% not getting 12v to the passenger headlamp as the drivers headlamp doesnt work on it either, but I guess a multimeter would prove if there is any voltage there at all, and a good time to check the pin conditions there too.

Yeah make sure all the pins are clean on the headlight plug

You can take each pin out too if you flick off the back of the plug and poke out each wire/pin, makes it easier to clean when the plastic is out of the way

Yeah I'll give that a go. Hopefully the plug splits apart and doesn't just split to pieces ! Also try and find the multimeter!
