Hi all first time posting sorry in advance if I ask the wrong question on here, I had a cluster issue which kept shutting of the immobiliser had the cluster repaired that cost £280 now car starts up fine everytime, after getting the cluster repaired my central locking does not work I cant even open boot lid, when I try to manually lock doors only front driver door will lock, took the car to audi they tried connecting vcds to central locking they said it seems to not be responding so they replaced the central control unit which would have cost £380 which has made no diffrence. Checked drivers side door cables all are intaked apart from two cables that have insulation Nik but aren't brocken, I'm back to square 1 any help will be greatly appreciated.
