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 Eddie,

Surprisingly, there are a few recurrent problems. If it's got a sunroof, check for rust around the edges. Engines need a cambelt change every 60,000 miles. A metallic whirring noise means there's pinking going on and you may need a replacement ECU. The crankshaft oil seal can leak, while clutches tend to go after six to seven years. Distributor caps and HT leads are both rather fragile. The CV gaiters on the driveshafts often crack and leak.

That's about it though. Pretty solid car.

Hi Patrick,

It should be fine, as it was the four-cylinder diesel that was troublesome on the E60 5 Series, and the straight-six engines are pretty solid. Just make sure that it has a full and complete service history and, if there are any gaps in the maintenance, walk away.

Hi Keith,

No, it's not a waste of time at all. It's almost always better value to keep and fix an existing car rather than pay the cost-of-change to upgrade to something newer. That said, if you're convinced you need a better solution, then you won't do better than to go for one of the many car-vans on offer now. The Renault Kangoo and Citroen Berlingo are the best known versions, but there are also similar models available from Fiat, Volkswagen and Peugeot.  My personal pick would be the Fiat Doblo, fitted with the 1.6- or 1.3-litre MultiJet diesel engines. You'll find the cabin surprisingly comfy, it's quite pleasant to drive, very economical and good on tax and massively spacious in the back. There's even a seven-seat version available if you want to be really popular at the school gate.

Hi Catherine,

A rough estimate of your C4's value should give you a budget of around €12,000 (and you might even do a bit better than that if you're lucky). Even at that level though, there is a plethora of cars matching your description out there. How about we start with something really classy? A BMW 316i maybe? Plenty out there, all priced around €11k and the 1.6-litre engine means reasonable tax and fuel economy even though it's a petrol engine.

Or you might need something a bit more spacious and economical. So we found a Citroen C5 Tourer estate with the 1.6-litre HDi diesel engine. It's a 2008 model so you'll be on the new CO₂-based tax system, it's massive inside and very comfy. Well built too.

Finally, you might fancy something a bit more compact and cheaper to run, and that budget opens up a world of Ford Focus saloons and estates with either the 1.6-litre petrol or 1.8 diesel engines. Simple, spacious, reliable and plentiful, you won't go wrong with that one.

WHat do you think?

Hi Michael,

Not really, no. The 1.9 TDI did get a minor reputation for having con-rod problems, but it was usually traced to another fault. Generally what happens is that a problem with the diesel particulate filter causes the engine management system to add too much fuel to the engine on start-up, which starts to thin out the oil, which then causes problems. There was another recurring issue with the air mass sensor, but that’s usually pretty easily remedied. Other than that, the old 1.9 TDI seems to be a pretty robust engine.

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 Fran,

We really like the Kia cee'd. It's a high quality offering that does everything well, is decently specified, refined, comfortable and relatively spacious. We wouldn't ever have compared it to the Renault Clio though, as it competes with the Mégane. The cee'd is bigger and more comfortable than the Clio. Saying that, the Clio is more interesting looking for sure and drives just as well.

In terms of diesel engines, Kia offers a 1.4- or 1.6-litre CRDi diesel and Renault has a 1.5-litre dCi unit. The latter and the 1.4-litre engine put out 90hp, but the Clio feels quicker and is a lighter car. Likewise it's better on fuel and a little cheaper to tax.

Try to test drive both in a scenario that reflects your daily driving. The cee'd is more refined and a better long distance cruiser, for example.

Hi Eddie,

You've not told us what engine you mean, so here's a list of the most common engines. Note that timing chains don't have a change interval and they should last the life of the engine if scheduled oil changes are carried out and all else is well.

 - 1.2-litre petrol: timing chain
 - 1.3-litre CDTi diesel: timing chain
 - 1.4-litre petrol: timing chain
 - 1.6-litre petrol (both turbo and NA): timing belt - change every 150,000km or 10 years
 - 1.7-litre CDTi diesel: timing belt - change every 150,000km or 10 years
 - 1.8-litre petrol 125hp: timing belt - change every 90,000km or six years
 - 1.8-litre petrol 140hp: timing belt - change every 150,000km or 10 years
 - 1.9-litre CDTi diesel: timing belt - change every 150,000km or 10 years

Hi John,

I'm afraid we'd need to know a little more, such as condition, mileage, which of the petrol engines is it (2.0- or 2.4-litre?), etc.

A rough estimation would be between €3,000 and €4,000.

Come back to us if you'd like us to narrow this down.
