Just discovered your channel, like the way you leave the mistakes in, makes it more real life cos I make plenty 🤣 My "fleet" is very similar to yours, E39 530i Touring and E46 330i convertible, and with similar faults so this is really helpful. The error codes suggest that my ABS ecu needs whipping out and going for repair, if you see this do you know if it's possible to drive the car while the ecu is off? I know the ABS etc won't work but it isn't now anyway
Thanks for checking out my channel and for commenting! You have a great „fleet“ indeed 😊 Ahh, I appreciate you seeing my mistakes as a positive - thanks! If you still need to use the car, I would suggest that you take extra care with accelerating and braking. You may have a problem if you have an accident for example - your insurance assessor could see that as a release of liability, because you know they’ll use any excuse! I didn’t let my wife drive ours until it was fixed and I only took it for a test drive to help diagnose the issue - you won’t have traction control, abs and esc available without that ecu. I easily felt that during the wintry conditions at the time. Take care and I hope you can get the ecu diagnosed asap
@@FullgasNoTraction Thanks for the reply, yeah you're right, should probably play safe. My other upcoming jobs are fuel tank purge valve and gearbox position switch on the E46 and brake light switch and replacement headlight covers on the E39, fun and games. Good luck with yours.
I like your heat shield idea. You right, it’s too close to the exhaust manifold and melts the ABS contacts. PS Your supposed to edit out the screwdriver incident.
Thank you! Was very cheap and easy! Hahaha - all my mistakes are shown on this channel, so my audience can avoid doing the same! Thanks for checking this episode out 😊
Heat isn't the cause of the failure. Perhaps it contributes slightly, but it's a manufacturing flaw combined with vibration. The DSC unit has internal bond wires, similar to those which connect integrated circuits (silicon chips) to their lead frames (pins). It uses very fine gold wires and thicker (roughly 26 AWG) aluminum wires between the connector board and the control substrate (ceramic printed circuit board). The thick aluminum wires have a fracture failure immediately adjacent to the board welds. It appears to be caused by excess bond wire length that forms an omega shape with acute bend at the weld. The higher mass and leverage breaks the wire. The thin gold bond wires don't fail, nor do other locations with the same aluminum bond wires that aren't formed into high loops.
@1djbecker Thanks for the explanation. I watched a few repair videos and decided that it was beyond my skills to try and resolder mine. The repair company said that mine failed in a typical way - i would conclude that your reasoning is why they typically fail. The repair on mine is still sound.
@@FullgasNoTraction It is a very difficult repair job. It certainly isn't a beginner project. You need to clean away the silicone gel, far enough that it won't flow back. That will, very likely destroy the adjacent fine bond wires expanding the repair to all of the bond wires. The pads have the remains of the welded wires, which are inconveniently in the center and reject solder. The ceramic circuit board doesn't use copper foil, so you don't get the intermetallic layer of copper dissolved into the solder that makes for a good joint.
Hi there - I used an aluminium foil sheet designed to reflect heat. It was around 0.5mm thick, so easy to cut. I finished the edges with rubber safety edging which just slides on. All available on Amazon and cost me about 10 bucks 👍🏽 The aluminium sheet has indents pressed into it to increase surface area.
@@FullgasNoTraction certamente| a me era successo nel 2005, poi ho sostituito la centralina abs e ho fatto lo stesso lavoro che hai fatto tu. fino a oggi 26 novembre 2022 mai avuto luci di errori e problemi
Молодец бро, хорошо работа!

Wow!! Sounds like you’ve had a lot of experience repairing them!
Hey, what materials did you use for the extra heat shield?
Hi there - I used an aluminium foil sheet designed to reflect heat. It was around 0.5mm thick, so easy to cut. I finished the edges with rubber safety edging which just slides on. All available on Amazon and cost me about 10 bucks 👍🏽 The aluminium sheet has indents pressed into it to increase surface area.
@@FullgasNoTraction brilliant thank you mate!
No oil drips out when you remove the control unit?
No - the control unit is electronic and should be dry. If there is oil, you have a damaged hydraulic block that is leaking.
@@FullgasNoTraction I see, ty 👍
Triple dsc error can be and ABS senor on wheel
@@mr_ali3692 yes, in the video I mentioned that I had just replaced the wheel speed sensors a few weeks earlier
bravo ,bisogna coprire prima la centralina abs se no il calore scioglie i circuiti e genera gli errori
Molte grazie - significa che hai guardato fino alla fine! Lo apprezzo!

Can you drive whitout modul ?
I would not advise doing that- but it will still drive, however you might not be insured
