Default Re: Traction Control(ASR) Need a Ginnie pig

Glad to see the site back.

I can now confirm the following: ASR/EDL can be retrofitted to our cars simply by swapping the hydro unit and computer from a car that has this feature. My 99.5 Jetta is happily NOT chirping its tires in 1st and 2nd gears.

What I have not figured out yet is the wiring - the unit is powered up already, all I need is the defeat, if I want it.

This mod makes a world of difference - remember my threads about the car having no traction? That problem is nicely remedied now, at least at lower speeds with EDL.

I would say that after the Upsolute chip, this mod was the most bang for the buck and the one I would do over all others besides the chip.

Eric (SVTWEB) has now also done this on a 2002 car, and has figured out the wiring.

Danix:

Thanks for all the great work on this project. I am really looking forward to doing it myself (sounds like less of a headache than PDC <img border="0" title="" alt="[Big Grin]" src="images/icons/grin.gif" /> )

Here are a series of wiring diagrams that deal with various combinations of ABS. They are from the European service information, so be alert for possible differences with your North American car.

Michael,

The PDF you posted doesn't show an ASR switch [img]images/icons/frown.gif[/img]

I don't have the knowledge to comment with confidence on the diagram. I will go to my Canadian dealer tomorrow and get the correct wiring diagram that shows the switch.

I'm pretty clear on the diagram - I still don't quite get how it works, as there is some momentary switching going on, but all I need to do is find the wires I need to tap. Again, Eric (svtweb) has this done.

I will soon have another hydro unit on the way for the next candidate...

Lito, Danix:

Try this diagram, it has a switch shown on sheet 5. Hope this is the correct one.

Put it to you this way -I thought the car sucked in the snow even with dedicated snows. Today with Zrated summer tires I was able to get home at brisk speeds without any trouble in some rain/snow mix. Like I said, it's right up there with Upsolute as a must have.

<font size="2" face="Verdana, Helvetica, sans-serif">What is the total cost/parts list for this project if I were to buy this new? What would be the difficulty rating from 1 (raplace valve stem cover) to 10 (installing quaife)? Down here in the rain I have very little traction and have to start off very slow to avoid sitting there and spinning my wheels so I am interested in this mod.

Thanks in advance

The Hydri unit is the only difference between the cars With ASR and the cars without.

The ASR/EDL hydro Unit's have an extra pair of solinoid valves to give it the capabilities of ASR.

The problem that I have is 2002 Vehicles use te Mk. 60 ABS/EDL/ASR unit, the 2001 and earlier use the Mk. 20......
<font size="2" face="Verdana, Helvetica, sans-serif">I was reviewing this thread and have to pick a nit here. The change from Mark 20 unit to Mark 60 occurred during the 2001 model year. Early 2001's had Mark 20. Later 2001 have Mark 60. My Golf built 12/00 has a Mark 60. VAG-COM reports it as such.

The Bentley (hardcopy page 45-9) indicates the Mark 60 is only ABS or ABS/ASR (no indication of EDL). However, the new CD version states there are 4 different controllers.

1C0 907 379 C / J ABS

1C0 907 379 D / K ABS/EDL/ASR

1C0 907 379 E / G ABS/EDL/ASR/ESP

1C0 907 379 F / H ABS/EDL/ASR/ESP 4MOTION

Bentley (hardcopy) reports 2001 Jetta's got the Mark 60 from vehicle #9M-1-094323. No number provided for Golf/GTI.

And I didn't notice mention of using VAG-COM or equivalent to code the control module according to the tables in the Bentley.

The date was a misquote on my part.. They started using the Mk60's in 2001MY.....

As for the rest of the post.... I'm not sure what kind of answer your looking for?

Cost - used controller/hydro unit, $100-500 depending where you buy it.
1 liter brake fluid, $10.
Having traction at last, priceless.

Difficulty - not very. If you can carefully use a wrench and know how to bleed/flush your brake fluid, it's about a 3 on a scale of 1-10, about the same as doing a brake job, but less labor.
I combined mine with a complete brake job.

In broad strokes:
- jack up car, remove 4 wheels
- (optional) R/R brakes all around
- remove airbox, MAF
- crack FL brake line to release pressure
- carefully remove brake lines (6) at hydro unit
- release 2 hydro unit mounting bolts
- install new unit, attach lines
- drain old brake fluid
- install new brake fluid
- pressure bleed entire brake system

No reprogamming of anything or rewiring was needed. To gain a defeat switch some wiring will need to be done, but I don't see the need unless you are racing or something.
