I've literally just finished giving it a tickle with some oven cleaner, came up lovely!!

Evening all 👋 Looking for recommendations for a decent cleaner to use on my EGR. As you can see in the picture, there is some serious build up! I imagine the valves are likely the same! What products and methods have people used with positive results for both EGR, and then with their valves?

Thought I would update this for those who might be struggling with dipped beam issues. As the diagram shows, the power for dipped beam is separate, it is fed from the headlight switch to the fuse board. Before the fuse board it splits into two, and feeds fuses 50+54. From there the yellow for nearside, and black and yellow for offside run straight to the headlight connector, then to the H7 bulb connectors. My issue i believe (don't take my word for it) stemmed from an oil covered earth point behind the headlight beneath the fuel filter holder. This likely caused high resistance, melting the h7 first, then taking out the other dipped beam by finally heating up the switch terminal to the point it melted inside the switch.

Thank you Alasdair! I'll check that thread out. I managed to find this on scribd, which will help massively, unless it's the wrong one 😂

Cheers mate. I had tried three different sets of bulbs, standard h7 55w, still no joy.

It does, that's what the 18 pin relay I mentioned relates to isn't it, 393?

Cheers Pete, so good to speak to someone who knows their 💩! Halogens I have. So I have power to 50+54 fuses, do wires go straight from that point behind the fuse board, or is there something else before they split off down the loom to the headlight connectors either side? With the one side going and melting, then the other side died, with no melting, confused me. I wondered what I saw online about the BCM eventually possibly cutting off the dipped beams completely if it notices a fault is still ongoing, is that a possibility?

Thanks Pete. I was going off what info chatGPT and google AI gave me. So what does control the dipped beam, is there a relay I can't find? 🤯 I am determined to find the issue without paying anymore for professional help 😂 I enjoy it, but electrics give me anxiety!

I've just ran a scan with the vcds and the BCM is showing a few faults, short to plus on them all.

That the BCM controls, or the relay 393?

Cheers Pete. Apparently there are no relays as such for the dipped beam, it uses BCM solid-state switching. The only relay I could find relating to headlights, is the bulb malfunction relay - 393.

Evening all 👋 I've got electrical gremlins! Are there any electrical BCM gurus here?! 🙏 Firstly, can anyone point me in the right direction to a layout of the BCM plug sockets, what they relate to?? A year ago I noticed my offside H7 dipped beam connector had melted at the earth point. I replaced it, still didn't bring the dipped beam back! I drove on for a month, then the nearside dipped beam died on me! I then brought a motorcycle and she's been neglected ever since, sorn and laying grubby 😞 I've got power to the fuses (50+54) No visible breaks or melts in the loom. A mechanic came out and plugged her in, poked his multi meter about for 2 hours, no power at the h7 connector. he left without a diagnosis 😭 Today I noticed the earth point under the fuel filter bracket was caked in oil, could this have been the culprit? After researching a little deeper, I am wondering if I have allowed the BCM MOSFET to burn out, by continuing to use the lights until the nearside died? Are these MOSFETS repairable by a specialist, or more costly than if I were to get a new BCM? Appreciate your time guys! Regards Craig.

Evening all 👋 Owned my 2005 fabia vrs for roughly 12 years, poor thing is in a state, slowly getting her back on the road 🙏 Needing to pick brains, hear this is the best place to absorb knowledge 😬
