[QUOTE 3799300, member: 9609"]if it has the 1.6hdi, keep an eye on the injector housings for signs of blow by, some are known to work a little loose, some of the blow by contaminates the oil in the cam over and turns it to sludge, this sludge blocks the filter to the turbo, very expensive. - do a search for "1.6hdi turbo problems"
when you are getting it serviced ask them to check they are tight (don't do this job yourself) - BMW use this engine in one of their small models, I have been told they are checking the tightness of the injectors at service
see this vid on what to look for

It doesn't look to be exactly the same engine, there are a few variants I think but I've just had a look and it all looks OK plus the inspection fella gave the fuel injection system a pass but you've successfully driven up my paranoia levels a bit. I might go and have another look now.
And, perhaps they've changed the design but I can easily change light bulbs, just a cover over the back of the unit.
