Well well.... the garage quoted my a min £150 for one rear sensor and one hours labour. Or it could be the pump and I would be talking £400 upwards.
After some research on the site I looked at the fuses in the boot. Located the fuse (30amp), pulled it out to find it had blown. Replaced the fuse and what a nice sight to see the rear suspension rise up to the correct ride height.
I guess my message here is, just spend 30mins researching on great sites like this one before you take it to any garage and hand over your money
