I agree, my Octavia has had 3 with cambelts needing replacing every 40000 miles...it's not what I signed up for when I bought the car. Originally it was 80k...then VW halved it. Its cost me around 1500 quid on top of the car. I much prefer the chain cams. I have 20yr old Nissans running chains with 200k on them..no issues. VW could match that but they don't because they factor in unreliability to keep you coming back to dealers or replacing cars after a 3 years. VWs are just money pits. I also had a five year old Audi 1.8t again another shi#box with sludge in engine, new injectors, alarm, all rubbish going wrong.
