Is the Golf GTI reliable?
The seventh-generation Golf GTI is, broadly speaking, reliable hot hatchback. Indeed, it does have a number of known issues (see below), all of which are detcable and repairable.
Parts are readily availble thanks to the vast number of Volkswagen dealserships and independent specialists in the UK.
Engine: Loud noises from the turbo, a loss of power, smoke from the exhaust and an engine warning light are all signs of turbo failure.
The IS20 turbo fitted to early cars is prone to failure and can even explode, causing shrapnel to fly into the exhaust and intercooler. Ouch. If it fails, upgrade to the more reliable IS38 from the Golf R.
High oil consumption is a common issue with engines. It can be caused by a worn piston ring, a faulty valve seal or camshaft cover seal. Be sure to check the oil levels and watch out for any big drops on a test drive.
Coolant can seep out from the underside of the thermostat housing (you’ll smell it) but it can be hard to spot a leak as the coolant has a coagulant in it. Check the oil pan for any residue and the car’s history to see if the housing has been replaced. Coolant can also leak from the water pump if it fails, which can cost £500-£750 to replace.
Wheels: The alloys are easily scuffed and, being diamond-cut items, they’re expensive to get refurbished. Also watch out for ‘white worm’ corrosion, because once it bites, the wheel needs a full refurb.
