So had the car with the mechanic getting the belts, water pump, thermostat and the other gubbings changed. Also fitted a brand new MAF sensor and an ABS pump and controller. Also replaced some of the vacuum hoses at the front as one in particular had been wedged in and severely damaged.
Had the codes cleared, but after a short (15 mile) run today, it's still lighting up the traction control and ESP lights on the dash. They come on for about three seconds and then go out. It repeats this about every 10 minutes and then stay on. When both lights are on, this is when I sometimes experience a stall. This is what a scan showed this evening:

Everything else is clear.
Mechanic said lambda sensors were working fine, so will need to go back to him on this.
Have done the usual Google search for the ABS code, but can't find anything of worth.
My main concern is that the car is going for its MOT on Thursday and I really need it sorted before then.
Any suggestions as to what else could be causing the issue?
