Got it done by a VAG specialist for £650 inc engine fllush and oil filter change. I had already done the cam belt days before tho so that save a bit of labour. Cams can be had from vwenginerecon.com for £300 ish. Then you need tandem pump seal, stretch bolts, cam cover seal and cam seal from
dealer. I got it done for me because I truly could not see the point doing it myself. This guy had the tools etc already and a nice warm
garage, he charged 3 hours labour
