Agree with Martin, been there, done that, ABS ecu was faulty. Was ripped off by repair outfit in Bournemouth (£400)! Only company who said they could test and repair, came back worse than when it was sent.With benefit of hindsight, I should have been warned when all of my reputable companies said they could not do it! Car eventually went to Peugeot, new unit fitted and coded, £250! HTH, Gwyn
