The ecu is behind a panel in the left side of the passenger footwell. It is the metal unit mounted behind a plastic unit.

Is that for the abs or the engine ecu to get another would it be a plug in an play or does it need reprogramming thanks

Thats the abs ecu it doesn't need programming to the car. Have a look at the service manual section of this forum for fault finding.

Page 950 of the service manual in the wiki-lude section covers fault 81

here is the link for the codes. i know you already have them but might be handy if someone else is looking into abs problems.

dont hear a lot about abs problems normally its 4ws problems - not sure if one can trigger the other.
ive had my BB1 for a year and not even looked at the abs stuff

i guess id better read up on how often the fluid needs replaced etc

Never had a abs code before an I end up with 3 bit like buses they all come at once
