Re: abs serv esp lights on laguna 2 progrees so far

you need to get a can-clip plugged into it to see exactly what is wrong. you really need the error read instead of blindly changing parts without checking whats actually wrong.

was the ABS pump replaced by a main dealership or was it one yanked off another car? if its off another car then you are probably going to have some problems doing diagnostics on it as its precoded VIN number will be different to the rest of the car. the ABS unit is made up of a motor, a hose block and the electronics module.

it might simply need the ABS reluctor rings recalibrated. they should be 48 tooth all round.
the errors should be cleared twice to clear both the UCH and the ABS modules memorys.
the can-clip has a recalibration procedure, that should then work on the ABS/ESP error. the ABS error will go away and then the esp should sort itself out after once the car is driving ok.

the sensors are magnetic switching, so are a pain to test on thier own unpowered, the car can easily do the testing for you with the can-clip.

since you bought 4 sensors which are now working ok and spare, you could try selling them on, on ebay to try and recover your costs.
