Thanks for your help. When I bled the modulator the fluid was contaminated so it sounds like it may be a dud. So frustrating to be thwarted at the last minute by an expensive-hard-to-get part! I have a spare ABS pump now so I will swap it over and give it a try, if only to rule it out. After this I guess a new ECU is another cheap try...... Anything to avoid changing that modulator again, it's a horror of a job.

ABS problems - I need your help please! I have been restoring a 94 Vogue SE over the last 12 months and have hit a brick wall. All work completed and booked in for MOT and on the way the brakes started sticking on. The garage were stumped, I was stumped. It is certainly not the calipers as they have been rebuilt. It is not the booster unit as I have replaced it with a second hand unit. I have re-bled the system and...... the problem is back. The pump is not running constantly and there are no lights on the dash. Perhaps it is the pressure switch or a valve, all I know is that something is putting the brakes on and it is not me! Any ideas, where can I start (again)...... Thanks all, Chris
