It seems as this forum (and the cars thumbup )become more and more popular that the usual what to look for when I buy threads become more and more frequent. So How about a Wiki containing the information and/or links to the other sources of information on the owners club site etc if we can't be bothered to type it out again. smile

I've started us off but often find I don't know as much as I like to think. So fill it in if you like it. Or let it drop down the list if you don't. smile

Common faults


Part Description Related models
Rear Calipers Rear callipers are known to seize on. Re-con parts are readily available. MK 1, 2 and 2.5 comes on with age
Sill Rust The rear section of the sills will tend to rust after 10 or so years. More common on UK cars. MK1 and older MK2 models
Elec. Windows Electric windows get slow and stick over time, if they still go up and down fully the runners just need dousing in silicone spray grease from halfords MK1 and older MK2 models
Oil Leaks The o-ring on the CAS sensor on the back on the cylinder head can perish and start to leak. On 1.8 cars the oil will drip onto the coolant feed pipes for the heater matrix, eventually making them burst. Also the Cam-Cover-Gasket can start to weep oil, usually if not replaced when doing the cambelt. both are DIY jobs to replace with a bit of care MK1
Clutch Slave Cylinder The slave cylinder can sometimes fail and the clutch pedal will sink to the floor. A replacement unit can be had for around £30 and can be fitted in around half an hour Mk1
Wet boot Often caused by a perished rain rail which is the plastic channel that sandwiches the hood around the rear deck. Replacements can either be fabricated at home or bought from specialist websites. Fitting takes around half an hour Mk1
Water in sills Drain holes can become blocked, trapping water inside the sills. 5 minutes spent clearing the drains with a wire coathanger should fix it Mk1
Transmission tunnel gets warm This can get quite noticeable and can sometimes be remedied by changing the rubber turret boot that sits under the centre console. Over time these can perish and allow heat from the drivetrain into the cabin. Simple and cheap to fix. Mk1
Noisey tappets There is often noticeable tappet noise when starting up. Perfectly nomal for this to last a few minutes, but investigate further if it persists. An oil change is often all that's needed, although it could indicate worn or damaged HLAs. Mk1
