Never heard of wet belts. Until I took a relative's Citroen to my local garage to see why the oil light was on, four months and 3,000 miles after a main-dealer service and with 30,000 on the clock. Before I finished the first sentence they said 'wet belt'. They said the belt shows cracking and wear. It's going back to Citroen for a warranty inspection. My garage has a wet-belt guy on call who does nothing but. Replacements start below 20,000 miles. With main-dealer servicing going up a third in price between service intervals, and wet belts being really needy in terms of oil quality and change frequency, this problem will only increase as people can't afford the maintenance. Having learned this, I will never buy another car without a timing chain. And if anyone knows the dumbf*ck who invented the wet belt, shove them in a bath of oil and ask them how they feel running round.
