Hi My beloved Octavia has just come back from Midland VW with a terrible prognosis, The rear diff is screwed. The cars unmodified and has only done 59k. I have had it 4 years done just under 30k mostly on the motorway. full main dealer service history and ibex service. they have just confirmed what i already suspected its making all the right noises so i have no reason to question them. They have provided me with a part number of 0CQ 525 010 S for a replacement which is an update from the one on the car. they are happy to fit if i supply. i think the only option i have is to look at a recon. i am not keen on ordering off ebay so i was wondering if anyone could point me in the right direction or offer any other suggestions.
