Numerous cooling system failures including 2 hoses and the radiator (water pump was new when I purchased the car - I should have taken more notice!), I was informed by the AA patrolman who rescued me that increased pressure due to leaking head gasket was probably causing all the bursts, and there was a slight sign of mayonaise in the oil filler cap.
Exhaust system had to be completely replaced, including the downpipe from the manifold - which resulted in a broken stud in the manifold that then couldn't seal properly ever again!
Petrol tank (plastic) split causing a slight leak.
Fuel return pipe on fuel rail started leaking.
Windscreen wiper mechanism was so worn that the wipers were hitting the bonnet.
Both bonnet hinges sheared off due to rust (the replacements started rusting within days of fitting - so ensure they are well greased) and they are a pig to replace as the massive door mirrors need to be removed to replace them!
Fuel gauge over read by half a tank - luckily the low fuel light still worked!
The resistor in the heater blower broke, so the blower worked on full or nothing - required a lot of stripping down of the heater unit in the hard-to-work-in engine compartment.
Rear brake cyclinders started leaking.
The front suspension ball joints and steering joints (inner and outer) were very worn and needed replacing.
CV boot "pin-holed" - leaking grease.
Various bits of interior trim broken or missing.
Rear lock mechanism broke and only so the hatch couldn't be opened (luckily a very hard whack opened it so I could fix it!)
Bonnet release catches very worn/broken resulting in the bonnet not opening either - but as luck (!!) would have the it the hinges were both broken so it was forced open from the back and a jab with a screwdriver released it!
Clutch was very heavy (from my previous experience with Renaults this is only fixed by replacing the entire clutch).
Roof lining all came unstuck and fell off in front of me while driving!!
