I have just changed my timing belt on my 2007 1.9 diesel after 60,000 mile and 6 years, I am a very steady driver, no undue accelerating and no speeding primarily because I would like this Multipla to last a few years yet. When I removed the old belt I was quite surprised at the excellent condition in fact it looked better than the slightly thinner replacement (A Continental part No.325771685) the only indication of wear was the tension pulley was well below it's recommended setting which could imply the belt had stretched a bit. There I was after reading some of the horror stories on the forum thinking the belt was in tatters and would break at any minute and cost me a fortune in repairs!! Having said that I will be changing this belt in 4 years or 40,000 miles.
