ASR Retrofit. What cars I should pull ABS from?

[ldavies93]

Looking to retrofit ASR to my AFN Engined 2000 TDI 110 Estate. My friend bought a passat at the same time as me, his is the TDI 115 AJM 2000 Estate - He has ASR.

His Part No for his controller is:
8E0 614 111 AH
Component ABS/ASR 5.3 FRONT D10

My Part No is
8E0 614 111 AB
Component ABS 5.3 FRONT D00

My question is I'm basically looking for cars breaking and wondered what cars I should be looking at, there are quite a few 1.8t sports around and I'm pretty sure a lot of them have ASR, so I could pull it from one of them.

Has anyone else done this in the UK??

what is ASR?

[ldavies93]

Blimey you were quick off the mark!!

ASR = Anti Slip Regulation (or sumthing like that)

It incorporates 2 technologies
A Low speed traction control holding back the geegees on acceleration (upto 25mph)
A High speed traction control using brakes over 25mph

Although I stand corrected

Hi, had a look on ETKA for the 2000 MY and the unit 8E0 614 111 AN is the replacement part for
8E0 614 111
8E0 614 111 AB
8E0 614 111 AM

Sorry but could not find 8E0 614 111 AH, also the only variances were for cars with the following, Navigation, Diff Locks (EDS) and cars with EDS + ASR, hope this helps.

hmm, bit confused now, especially if the AH Part code doesn't exist!

Can anyone post their ASR capable unit part no up from their b5/5.5 car to cross reference.

I'm basing all my knowledge on a post on tdiclub that basically allowed a Mk4 Golf/Jetta be upgraded with ASR through a simple abs module and/or pump replacement

Have you had any luck with this yet? A friend has just got a '97 afn that's going to be towing so this would a very handy mod

[ldavies93]

No, Still looking around, and I crunched my wing a couple of weeks ago, so I'm sorting that out at the moment :doh:

[nuttinnew]

ou've got me intrigued now especially as I need a brake fluid change anyway so it adds some impetus and seems very worthwhile before tuning...

[ldavies93]

definitely check out the tdiclub link, very interesting read!!

[nuttinnew]

Yup, been having a read of that, defo worthwhile imo.

I thought that it was brakes for less than 25mph and geegee restraining for higher speeds - that would seem right as you dont want lots of braking to control things at high speeds - but maybe its me that should stand corrected!

[ldavies93]

Managed to pick up a ABS pump/ecu from a 2002 passat so once I get it back, I'll be able to check it out and see if it'll do traction control - woohoo!

Then again it was cheap enough (£10) to toss if it wont fit.

I was in a breakers yesterday and the only two cars with asr were missing the pumps

I would've thought that at higher speed brakes would be better suited for traction control as letting off the throttle can only do so much but at high speed if you start getting out of line some more drastic action would be required. Just a thought mind.

8) I was in a breakers yesterday and the only two cars with asr were missing the pumps

Everyones out to do the upgrade

Just found out the guy does salvage, so I'll ask him for the ASR switch as well.

[ldavies93]

Guy announced he's listed the pump twice on ebay by mistake and I hadnt paid quick enough - problem was - I was waiting for his reply on getting the ASR switch as well. Dammit!

I then found a ABS unit on ebay poorly worded and I won it at £6

However its a b5.5 pump and the wiring is for a CAN bus system - NEXT!

The hunt goes on and I shall find one sooner or later.

Seeya!

Grrrrrrrr

As far as I know traction control is a very basic form of ASR they operate in different ways. Traction control is easily implemented on any car with ABS by using the ABS sensors to measure wheel speed it is possible to detect a wheel breaking traction and reduce the power to the driven wheels to restore traction.
In a normal car with no limited slip differential the power will go to the wheel with the least amount of grip and that wheel will spin. If you try to pull away with one wheel on ice and one on tarmac the power will go to the wheel with no grip spinning that wheel meaning you don't accelerate.
ASR works by applying the brake to the wheel that is spinning and this means some power is then passed to the wheel that has grip meaning you are able to accelerate.Very useful at slow speed.
So ASR is advanced Traction control using EDL (Electronic Diff Lock).
It also works at high speed but it depends on whether both driven wheels are spinning or one is spinning on what it decides to do.


The following is from http://www.italiaspeed.com/new_models/2 ... /safe.html

ASR (Anti Slip Regulation)

ASR (Anti Slip Regulation) is also built into the ESP system, optimising traction at all speeds, assisted by the brakes and the engine control.

The device monitors the wheel speed calculated by the ABS sensors to establish the amount of slip and triggers two different control systems to recover grip. When an excessive demand for power causes both drive wheels to slip (for example, aquaplaning or accelerating on an uneven, snow-covered or icy road surface), the system reduces engine torque by decreasing the throttle valve aperture and thus the air flow. If, on the other hand, only one wheel slips (for example the wheel on the inside of the bend, after acceleration or a dynamic change in the load), this wheel is automatically braked without the driver having to touch the brake pedal. The effect is similar to that of a self-locking differential. This gets the Grande Punto out of any difficulties on surfaces where grip is poor.

ASR is engaged automatically every time the engine is started, but can be excluded by a pushbutton on the central console. ASR must be excluded when snow chains are fitted because in this case, in order to transmit torque to the ground, the wheel needs to be able to 'accumulate' the snow, with small slips that the ASR tends to avoid.

In my humble opinion this mod is a total waste of money and time. You would be better spending the money on a decent suspension setup and a good set of tyres.

[ldavies93]

Mental note to self: Part no replacements for AH are:

8E0614111AQ
3b0614111AQ

And what is that guy going on about

Of course its better going for a decent suspension/wheels, but I bought a ABS unit for a 2003 car for £6, you telling me I can get the same sort of deal Besides my main reason is "to just have it!" Further, suspension work and tyre work dont help you on mud in rural areas (thats my excuse and I'm stickin to it lol:)

[ldavies93]

My £6 mod didn't work unfortunately the unit was off a B5.5 and uses a different communication bus. However

I've just sourced a Unit from a tdi sport car for £50 delivered > not as cheap as before but it is cheap:D

Should arrive in the next couple of days, then I can get ASR working

Thanks,
