Hi Pat,

They're generally quite solid, but there are a few crucial checks to make. Alternator belts can wear and make a horrible screeching noise when they do. The HDi engines need an additive put in at 60-80,000-mile intervals. A heavy clutch pedal may mean clutch failure is imminent. There are diesel particulate filter issues - if the DPF light comes on and stays on, run the car at medium revs in a low gear for several kilometres to try and heat up the exhaust enough to burn out soot from the DPF. If that doesn't work, it's an expensive part to have replaced. Dual-mass flywheels can get warped and cause a juddering effect. A lumpy idle or excessive exhaust smoke may mean that the exhaust gas recirculation valve needs replacing. 

Inside, the radio and its LED screen can be fragile while, if the air conditioning isn't puffing hard enough, it usually means that the pollen filter needs emptying. Underneath, watch for the front suspension being out of alignment and for excessive tyre wear - 407s were always quite hard on their tyres. A groaning power steering system means the pump needs replacing too.

Hi Charlie,

Skodas tend to be very reliable and well-made, but there are a couple of recurrent niggles on the first-generation Fabia that need checking. Both fuel and water pumps can prove fragile, so check that the engine isn't cutting out and that there's plenty of coolant in the water tank. Check also for 'mayonnaise' - white deposits of mixed water and oil that give away a leaky head gasket.

The sensor for the power steering system can fail (a red steering wheel-shaped light on the dashboard is the tell-tale) and water temperature sensor failure is the most common cause of engine management warnings. The on-board computer that diagnoses when the car needs a service needs to have the correct grade of oil (it measures the quality of the engine oil to decide on the service interval) so check that the recommended oil has been used.

Check for a heavy clutch (the master cylinder could be on the way out), collapsing driver seat, broken speedo illumination and water getting in through the rear door seals. If the dashboard is rattling, it's usually a mounting bracket behind the air vents and can be easily packed with foam to stop it.

If it passes all of those tests you've found a good one!

Hi Shane,

As with any current turbodiesel model, the first thing to check is the diesel particulate filter. Drive the car at a steady 2,500rpm in fourth gear for around 16km and see if the DPF warning light goes out. If it does, all is fine. The 2.0 TDI engine needs a cambelt change every 110,000km so make absolutely sure that's been done as it's an expensive job and a total engine failure if it goes when you're driving.

If the car has the MMI infotainment system then make sure that all the functions are working, as problems are apparently hard to diagnose and expensive to fix. Check the front passenger floor mat for dampness - the air conditioning system can sometimes flood with water draining down from the windscreen and leak onto the floor. Glovebox catches and (more worryingly) seatbelt anchors are prone to wear, so check both. Watch for tracking issues on S-Line cars with sports suspension. A dull thudding noise from the front might be a worn anti-roll bar drop link too.

Hope that helps

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 Kevin,

The Volvo S40's engine is susceptible to a few issues that are, unfortunately, quite expensive to fix. Without seeing the car or message for myself, I'd suspect that it means turbocharger failure due to build up of sludge in the oil supply pipe to the turbo.

You'll need to get the car along to a good mechanic to confirm this for you before deciding on how best to remedy it.

Hi Alison,

It should be pretty solid. Kia has always had a good reputation for quality and reliability, even back before the days of the seven-year warranty. We have heard of old-shape Carens having engine failure problems, but it’s a difficult issue to diagnose ahead of the fact. Just make sure it has a full (or at least close to full) service history.

Expert answer

Hi Bob,

The Fabia is a pretty rugged car, but obviously with this one being 16 years old now, you’ll need to thoroughly check it all over. Common failure points are fuel pumps, water temperature sensors and water pumps, rattling dashboards, clutch master cylinders, leaking rear doors and dashboard lights. Economy should work out in the low-forties, in terms of miles per gallon, depending on how and where you drive it.

Generally, I’d say it’s an excellent first car — easy to drive, roomy and robust. 

Expert answer

Hi Kevin,

That could be caused by a few different things, but the most likely for that 1.6-litre diesel engine are either a clogged diesel particulate filter (DPF) or the failure of the turbocharger. Either way you need to get the car to a good mechanic as soon as you can to have it repaired.

Expert answer

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.

Hi Adrian,

I'm afraid so. Quoting from the NCT manual:

"Ensure the malfunction indicators for Airbags, Electronic Stability Control (ESC) and Electronic Braking System (EBS) / Anti-Lock Braking System (ABS) and Parking Brake malfunction indicator are in working order."

"ITEM: Malfunction Indicators for Airbags, Electronic Stability Control (ESC), Anti-Lock Braking System (ABS/Electronic Braking System (EBS) and Parking Brake."

"REASONS FOR FAILURE: Not working or indicates a defect in the relevant system."

You'll need to get that looked at I'm afraid.
