Mk3 gti abs pump/ecu

[Marb]

Hi, does anyone out there know if the abs pump/ecu on a mk3 gti 16v is the same as 8v (for same production year) Pump looks the same, but I wonder if ecu is different?  My 16v is going to fail its next mot on abs not working and I know of an 8v part going cheap.

Pretty sure that 8v and 16v are different.

Yes they are different, 16v has a very basic traction control that they share with the VR6
in theory the 8v one should work -its a stand alone system, been retrofitted to Mk2's
btw The important part number is the one on the ECU black box underneath.

The numbers on your existing ABS hydraulic pump must be EXACT with the one you change too. I had to change mine, got it off a SEAT.

The numbers can be found underneath.

Ok, thanks everyone for that, almost wasted some money there!! I'll look out for a 16v one.

Don't waste your money! All that counts are the numbers. As i said, i bought mine from a SEAT. Take a mirror and look what it says under yours. Just because you take it from a 16v dosen't mean it add up automatically.

I hadn't thought about a mirror. I was thinking about buying a 16v abs unit in advance so I got the right one   and avoiding the car being off road for too long whilst I look for the part. Many thanks for your advice. smiley:

Not even all the 16V/VR6 have the same part number for the ECU.  Mine ends with 'A', a lot of others end with 'E'.

I can't see any numbers on the underside of mine, with or without a mirror!

Underneath it looks like this (and the numbers you want to see, that have to be exactly the same with the one you're swapping)
