hi thanks for the reply.
yes it is a xantia 1.8 16v, i don’t think they did the XM this engine, if they did it would barley move form a standstill!
My mech skills are not that good i can do filters, LHM change, discs pads, but not the belt.
The garage quote £140 for the whole belt kit fitted, which seems very good, most others are nearer £200+.
I came on his forum as maybe someone may have tried this (or another) garage for their XM or other cits. i don’t like to leave my car with a garage if i can avoid it, esp. crap ones
