Update
Just to let you all know i got a friends mate (works for a main dealer) to do the job for me and its all sorted. the problem was the 3 solenoids metioned. he done the job on my driveway. took him around 4.5 hours as he didnt have the use of a 4 poster, (axle stands had to do!)
he charged me £220 all including parts and labour. i was well happy with that
