Replaced faulty abs pump but now can't start the car as immobiliser is on and can't disable it any ideas? Does the pump need brake fluid bleeding thro' to override the immobiliser.

The ABS system need to be paired with the engine ECU, as it's part of the immo system....
Go to dealer or someone with dealer like tools.

Thank you Alex will tell the mechanic doing the job and hopefully that'll be the answer, Cheers

Thank you alex_pescaru for the info re my new abs pump which was spot on and solved my problems. My local dealer paired both components as you suggested and all is well now. Cheers

You're welcome! Glad that I could help.
