Hi Gavin,

Here's the checklist for a 2002 Volkswagen Golf (hatchback or Estate):

- Check that alloy wheels have had copper slip grease applied behind them at each service, or the alloy can react with the steel hub and cause corrosion.

- Make sure the headlamps are in good condition, as they're a bumper-off job to replace.

- The rear screen wash-wipe can leak and run into the lock, shorting out the alarm and central locking. The door locks in general can give trouble.

- Most Golf engines need a cambelt change every 40,000 miles (64,000 kilometres). Diesel engines tend to get through a lot of oil.

- Clutch release bearings can wear out easily leading to a hefty clutch action.

- Ignition coils can burn out.

- A whirring noise could be a water pump failure.

- Slow starting or engine management lights often mean a temp sensor has failed.

- A tapping noise on start up may mean you need a cylinder head rebuild.

- If the car has sluggish acceleration it could be a crank or camshaft sensor failure.

- And if there are any issues with any of the main instruments then he whole display has to come out and be replaced.

That's a long list, we know, but if the car you're looking at passes those tests then it's likely to be a good one.

Hi Tom,

Power steering aside (that's strange...) it really sounds like you might have connected the battery incorrectly or shorted the battery somehow. Have you any way to safely test the battery?

If you're not confident in finding the problem for yourself we'd really recommend you get an auto-electrician or a mechanic to take a quick look for you.

Let us know how you get on.

Hi Frank,

This is a pretty solid buy in general, though insist on one with a decent service history and do a thorough check of the car. Electrics can have gremlins in them so check each and every switch and button. Likewise, if it's automatic, walk away if the gearbox is very jerky and holds onto the gears for a long time even when you've not got your foot down. Watch out for knocking in the suspension too, as that could mean costly repair bills.

Hope that helps

Hi Hugh,

Odds are that this is being caused by the switch that operates the warning. Open the door and take a look for a spring-loaded switch and inspect it for damage. After that it's worth checking the wiring to it. Then it's probably best to consult a mechanic or auto-electrician.

Hi Dolores,

They’re pretty shoddy, to be honest. The alternators are troublesome, as are turbos on both petrol and diesel models. Head gasket trouble is common, and the timing chain on the 1.6 petrol needs regular checking. Electrical problems are common and the roof mechanism on the CC model is spectacularly unreliable, often getting stuck half open or closed. The timing belt/chain question rather depends on which engine you’re talking about, but economy will work out at around 35mpg for the petrol models, or 45-50mpg for a diesel.

Hi Jakub,

Right, here’s what we’ve gleaned with a little help from Nissan and a dive into its archives…

There were basically two specifications of Primera from 2002 to 2008. The entry model was an SE, which came with a full colour display in the centre of the dash, trip computer, colour reversing camera (one of the first cars to deploy this tech, as I recall), climate control, power steering, front and rear electric windows, electric mirrors, height-and-lumbar adjustable driver's seat, CD player stereo with six speakers, ABS with EBD and brake assist, six airbags, front pretensioners for the seatbelts, remote central locking, alarm, 16-inch alloy wheels, front fogs, chrome door handles and body coloured mirrors.

The T-Spec model got all of that and added auto dimming rear view mirrors, auto wipers, leather trim, power and heated seats, steering wheel audio controls, premium audio system, active headrests, cruise control (for the 1.8 petrol model) and 17-inch alloys.

Hi Eoin,

The rear wiper is an easy one to start with as it's very common with this car. The wiring loom gets broken near the hinge for the hatchback so you'll need a good mechanic or auto electrician to fix that one, but it shouldn't cost a fortune to do.

It's trickier to assess your fogging-up problem from afar. It essentially means there is moisture in the car somewhere, though sometimes simply cleaning the inside of all the windows properly sorts this out. Other than that, avoid using recirculation of the interior air, do use the air conditioning if you have it and, if all else fails, consider leaving a dehumidifier running for a while in the cabin to take out moisture.

Hope that helps

Hi Danny,

While the Frontera is cheap to buy and not bad off-road, it really is not a 4x4 we'd recommend due to its lack of quality and poor reliability record. The weak points are the engines and electrics. If it has not been serviced then best to walk away. The steering and suspension systems have also had problems and the Frontera is prone to rust.

Sorry not to have better news!

Hi Paraic,

First and foremost is the running costs, but I guess they're on the same level as any large SUV-based commercial with an automatic gearbox - they're heavy on fuel and tyres, etc.

Other than that, while the Discovery 3 is proving to be more reliable than its predecessor, it's hardly the most dependable truck of its type. Some cars are perfect, but others have loads of issues, from the electrics to the air suspension and even to full engine failure.

Don't settle for anything less than a full service history and make sure you have the car checked out by someone that knows what they're looking at too.

Hope that helps
