Replaced the bulb, still no left beam. Discovered that left/right low beams are on fuse 57/58 respectively. Switched the two fuses, right beam again lights up fine, left no. This is logical since fuse 57 controls also the light level adjustment which has been working all along.

 

I tried 3 different bulbs to no success. Unless the bulb socket has to be perfectly in place (the socket, not the bulb in the socket) in order for the beam to light up then apparently it's no burnt bulb nor fuse, any ideas?

No ideas? I thought it would be something straightforward other than bulbs or fuses which i'm not aware of, maybe it's more of a mystery than what I thought!

 

Only reason I'm bringing this up rather than a visit to the dealer's is it's a 100 km trip and I will be there by the end of the month for the annual service anyway. I would like to avoid getting another half day off just for this but would also like driving with both my low beams on in the meantime.

check the cabling at back of light cluster,

I had this with my DRL - checked the bulb and changed the fuse twice.  Then took it to the dealer, who changed the fuse again and it fixed it.

 

Maybe they have anti-tamper devices on Fabia lights...!

You should never try to do work like this for the first time in the night and under poor light conditions. I had a look at the user manual yesterday and realised there were two different projectors for low and main beam and guess what... I was playing with the main beam one instead of the low beam.... 

 

Bulb replaced and all is ok. Wondering if it will do any difference having a Philips Xtreme vision and a no-name H7 on at the same time. Probably better order another set and keep the 2nd one as a spare.

when you say one of each bulb at the same time, do you mean one of each in the dipped or a set of each, one in dipped and one in main?

It is recommended that you replace both bulbs at once.....in an ideal world

Previously, I had only replaced the low beam bulbs with Xtreme vision H7. After all it's the low beam that all the fuss is about of not being adequate etc. Main beam was untouched. So now that one low beam bulb died, I replaced it with a spare no-name H7 I had around. Meaning thereafter, my low beam consisted of 1 philips xtreme vision and 1 no-name so I wondered if they would look weird due to difference in lighting power etc.

 

Anyway, I've already ordered a set of Xtreme vision and will use one of them in order to have the exact same bulbs again.
