Thinking of buying a Berlingo. Hopefully going to see a 2003 1.6 petrol this weekend, which has covered 40,000 miles. Can anyone tell me what the cam belt change interval is on a petrol Berlingo? And also on the HDI, just in case I spot one in my price range? Someone told me it was 80,000 miles which seems a bit high, and then I read somewhere else another guy recommending changing the belt at 36,000 miles. (that was on a 1.9 diesel) New to Citroens. Any advice appreciated. Thanks.
