VW Audi Bosch motronic 5.3 ABS repairing

First: I do not take any responsibility (failure of your car, car brakes, accidents).

I do not sell any DVDs or instructions.

This is Bosch motronic 5.3 ABS module repairing.

I received opened module. Do not use dremel. Do it by stanley knife or scalpel. Do it gently and carefully. Cut the gray silicone around cover. Finally, close with a waterproof silicone or glue, but first test if works.

I am 99% sure that you have error on this wire, but you need a lot of soldering experience to fix that.

[jvolk0]

What are your simptons?

Yes, problem is always with the silver wire (aluminium). Gold wires are flexible enough (vibration insensitive).

No you do not need programing. Car must recognize working ABS module and turn off red light for brakes. You should erase errors via CAN bus.

If you do not have this module in car you will not have ABS and EPS... little bit risky...

[jvolk0]

You can solder aluminium under motor oil (prevents oxidation). Module works now over a year, without any problems. And if module breaks again you will se a red light or error message on dashboard... I don't see any problems here.. if you drive with red light on dashboard.. your problem ;)

You better fix sensor wires too.. it's ABS module and EPS will not work properly.

I don't know.. I don't own VW, but if module is like this in video it is 90% this error. In this month I repaired third one (Audi 98 and 2x VW Passat 99) - same error - aluminum wires. You can take a photo of module (on the right side of the car hood) and send me. I will try to recognize a module if is like this one.

Thank you so much for this video!! I had exactly this problem in my module and I had never been able to fix it by myself without this video.

@MrElvey Oh, I see better when I watch it in HD. They'd become detached and you re-attached 'em and they both go to the same connector; the wire is just soldering wire. The clear grease is the acid or to keep solder off the other connectors?

[MrElvey]

@MrElvey

Oh, and one more thing(TM): ECS/ESC saves many lives. Totally worth repairing. interesting stats from the NHTSA's (IMO sophisticated)

Statistical Analysis of the Effectiveness of Electronic Stability Control (ESC) ...File 810794.PDF

•Overall, ESC reduced all fatal crashes by 14 % and police-reported crash involvements by 8 % for passenger cars. Only the 2nd (8%) decrease is statistically significant.

Resoldered ESCs are FAR safer than those unrepaired (due to the 4-figure cost)!!

[MrElvey]

@MrElvey (continuing) From what I read here, it sounds like my module probably has this problem. I can't actually see what you're doing in the video. Are you basically replacing two aluminum wires with two gold wires? (And somehow not shorting anything out - it looks like it's a rather difficult solder job.)

ANYONE near Oakland CA willing to work on this for me?

[MrElvey]

@jvolk0 I totally agree with your reply to @diagnet !

I have a 2000 VW New Beetle 1.8T and the ABS ECU (I THINK it's part 1J0 698 417A 98-09, or at least that's a valid replacement) is malfunctioning (the codes I get are that 3 of the ABS speed sensors are intermittently failing, and the two lights typically turn on when I hit a bump, and go off a while later.)

My mechanic says that he can't replace the module with a used one off ebay; he can program a new one but not reprogram used.

hello i have the same abs unit on my saab. i really appreciate the video. one question. what type of solder should i use? and what temp did you have the solder iron? first when i tried to do it i did not have the correct acid flux and maybe my solder was not hot enough but i couldent melt the existing solder on the pin, should i melt that existing solder or just add on to it? thanks hopefully i will go buy the supplies and do the job today

[jodogzzz]

@popesmag Yes they are

[popesmag]

are they both on the same pin?
