I've got an S16 (M reg) and it comes with a Bosch ABS unit - which has never worked. I've changed all the sensors and now managed to swap over the ECU to one I found in a breakers... but it still doesn't work! (there is a chance that the ECU I've found is also faulty I guess...) Anyway, I'm now going to try to change the pump unit itself over- but am expecting this to be a total bgger re bleeding.... so wondered what I'd need to do to convert to a GTI 6 ABS set up - which I understand is easier to bleed- and are certainly more plentiful in supply.

Anyone got any experience of doing this?

Assume I'd need the ABS unit, wiring harness and pipework...

Thanks!

Thanks for info - there are three harnesses which plug into the ABS unit I've got. One looks like the interface between the ECU and the pump - the other is a four pin plug (square in shape) and then there's a more sturdy longer multi pin (bit like a scart plug) plug. Will inspect the pins again - but is a real bgger as have changed all the sensors and still no joy!

Will have a go at swapping over the pumps themselves, but they are notoriously difficult to bleed apparently.

Any advice on exactly what to check re the power feed terminals?

Thanks!!

Mate - thanks for the offer - but you're a year late...!!!!! and I've fixed it so it all works fine now!

Changed the pump - and also the rear sensors - and had to clean up the brake light wiring loom as had corroded A LOT - leaving gunk over the terminals (like when you leave batteries in a remote for 5 years or so.) - that was shorting out and causing the brake light switch to log a problem in the ABS ECU - all sorted and works fine now.

They tried to help I guess!
