ABS and EDS

[Hungry_Horse_1955]

I’ve searched the forums but there does not appear to be anything on the EDS (Traction Control) system.

What I want to know is was EDS standard with ABS? If not, I assume the ECU in the boot is different, in which case how do you tell the difference?

If it is a different ECU, can you just swap them over to upgrade to EDS?

Are you talking about syncro busses here or did they do EDS on the golfs & saloons too?

According to my Golf Handbook, it was fitted to Golf Syncros!

The two seem to have been fitted together, where fitted.

blimey – lhd only tho surely? or golf country perhaps? News ot me in any case – i thought only the vans had them.

it uses the abs master cylinder so LHD only. think it’s just a feature of the abs system, no massive gain from having it as far as i can see

LHD Golf & Passat Syncros were fitted with the ABS & EDL as an option. The EDL is a function of the ABS system, so the two features were only available together.

The EDL is just the ABS computer detecting one wheel spinning faster than the others, at which point the System applies braking pressure to the spinning wheel to slow it down and keep it under control. This forces the Diff to transmit more power to the opposite wheel. The EDL only works at speeds below 50km/hr(30mph). The bad side to this is that the EDL system will slow the car down somewhat due to the brake application.

Because of this, the EDL takes some of the fun out of winter driving. []My Passat G60 Syncro is very difficult to put into a powered 4 wheel drift in the snow unless I get the wheel speed up over the 50km/hr limit, then the fun really begins as the car changes personality![]

ah ok thanks les – sorry yes I was thinking diff-lock meant changes to the diff but it’s all done with the abs…

tbh I’m happiest without the computers interfering in the driving – at that level at least.
