I know its a bit of a "How long is a piece of string?" question but my 2005 (early?) Panda Multijet with almost 120k miles on the clock has started slipping the clutch (presumably- as revs rise when turbo kicks in without any effect on speed etc )It pretty much has to be 'forced' to do this and is fine for general driving .Anyone who has had trouble with their Panda Multijet's clutches estimate how long before I need to replace it and/or driving becomes akward /impossible?(Car has been very well looked after )
