I may consider adding that also thenIn case of a short, the small wire used wouldn't make enough fault current to blow whatever main fuse that feeds those termanls by the relays. Safety, mostly!
I'm an electrician by trade and have seen bad wiring burn and never trip the breaker because they were too small for the protective device-breaker or fuse.
Of course it wasn't done properly to the electrical code, but that's another story
What's the difference between ASR and EDL? IF they are all in the same pump unit, how do they work differently if they both reduce wheel spin? I looked up ASR and it says it works above 40 mph, EDL is below 40 mph but my old 1.8T wagon with ASR, worked off idle as I would pin it in the snow and it would kick on?
ASR reduces tire spin by reducing the power to wheels
"ASR only operates in conjunction with the electronic accelerator (E gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning."
EDL pulses the brakes of a spinning wheel to help direct the power to the wheel with traction.
"The electronic differential lock (EDL) permits smooth, comfortable starts on road surfaces that do not have a uniform coefficient of friction. If a wheel starts to spin, EDL brakes it as necessary so that power is transmitted to the wheel with the better traction."
Thanks, great quotes.
I have 2 ASR units, going to wait for an EDL unit. I drive a lot in the snowy mountains so I think EDL will be better for the wagon, especially with the wife driving.
1) 1C0 907 379 C/J ABS
2) 1C0 907 379 D/K ABS/EDL/ASR
3) 1C0 907 379 E/G ABS/EDL/ASR/ESP
4) 1C0 907 379 F/H ABS/EDL/ASR/ESP 4MOTION
ASR/EDL are one unit.
ABS only or ABS/EDL at the very least without ESP
Why 21505? How did you come up with it?FYI I have a late 2001 TDI Golf w/ the MK60 pump, and the ASR/EDL works after swapping the ABS pump without reflashing the ECU, which there seemed to be some question over, since the late '01 models are similar to the '02 models. I did have to set the ABS soft coding from 4097 to 21505 to make it work. I can now see the triangle appear on the gauge cluster when the tires slip...
For reference, the pump I used is a 1C0 907 379 D removed from an MK4 GTI (according to eBay), which cost me $30.
Honestly, I was in a hurry and googled it, and that seemed to be what people on vwvortex said they had as factory coding if they had factory ASR MKIVs. I didn't know about the instructions you posted above.Why 21505? How did you come up with it?
