Needs to go on star diags too many components on the ESP to guess.

Brake light switch would be my first port of call , £12
Did you do the lock to lock and back again twice once you had fitted it ?
NOPE didn't do that,didn't knew had to do that. can I still do it?
had it on star last week no fault showed but the esp light went out on the way to him, however it showed ignition not communicating however ignition is doing its job. still changed the sensors as the light was intermittent.
Cheers
Have you had any work done on the car recently which could have caused the new problems?
Shaz open the ECU box, top right corner of the engine bay, there is a silver ECU at the back pull the connectors off and check for oil in the connectors.
Also disconnect the battery first!! Only reason I mention this is because I have the same car with this fault with me at the moment.
