MK5 VW Jetta BRM Glow plug harness replacement

[@cam3002]

For future viewers: This video was helpful, I did my glow plug harness this past weekend and it is now working as stock. Once you get the air filter, battery, and battery trey out of the way, there is a lot of room to work with. The most challenging step for me was soldering the connections but that is more related to my lack of experience. I used weather tight heat shrink which I've been told is the proper way to finish soldered joints. HTH

is there any color code to match each cilinder with the proper wire?

[@cam3002]

@@sergioalvarez4979 It was very self evident, the new wire color code matched the old wires. I just match them. I really don't think it matters as far as activating the glow plugs goes, but I matched them just in case. HTH

@@cam3002 that's ok, I got an non OEM part and I thought the colour code wouldn't be the same, but checking car instalation it's the same. Many thanks :)

Thank you! I will be doing this this weekend!

[@laszlo9285]

Thanks. I've did the same procedure and worked out well.

Hi, congratulations for the video, I have to do the same job. Cables have a sense of connection ? or do they connect randomly? Thank you very much

Did the harness y to another module near the head? It's like a circular connector to the side near the high pressure relay

Do the replacement looms match the wires to original VW loom

[@ionutbalaci4171]

Can do the same for passat b6 1.9?

[@wesleybrabant3595]

How'd it turn out? Code go away? Riding open that main wire harness was a lot of work you really didn't have to go through.

Does it matter where u solder each wire ? Are all 4 the same or are they color coded

[@taylorbrown4276]

They are color coded. Doesn't matter where you solder them but you would want to replace as much as the harness as possible. I have seen people just snip the harness by the head and splice it right there to the new one but this adds extra length and the wires rub up against the head and short out

[@ionutbalaci4171]

What are the colors codes?

[@mitchelwern4672]

do u know what casues the oil leak on the right front side of the engine right by the head gasket?

[@TestedMT]

It's probably the Tandem Pump, you can buy a new one or reseal the old one

[@taylorbrown4276]

Also can be leaking where the injector harness goes into the head. Kind of a job to seal as you have to pull the valve cover and pull out the harness assembly

Thank you brother

[@wesleybrabant3595]

Smart.

Thanks for uploading your video. I used your method and successfully installed a new harness in my Jetta Mk5. It took me 3 hours. I took a long time to figure out how to remove the air box, battery etc. I found a KZbin video showing how to undo the air box, which others may find useful: kzbin.info/www/bejne/g6bbnZyPhL59m9U

Glad it helped

Hi! I need some help! I found the relay for the glow plug. But I am unsure what one to cut open! I have a video, but I cannot post it here. Do you have Facebook or insta?😅
