Hi Alan,

By 2006 that 1.9 TDI engine was nearing the end of its life, and so had most if not all of its earlier issues (injector problems, air sensor failures) ironed out. As for the flywheel, yes there does seem to be an issue with it occasionally, but the way to tell is to listen to the engine, getting your head as close as safely possible to where the gearbox is located. If you hear a rattle, or feel an obvious vibration, it's probably the flywheel.

Hi Martina,

Both cars you've chosen there are pretty much neck and neck in every area, bar one. The Passat is arguably a little more 'premium' in its feel, the Mondeo is better to drive and we'd say a touch better looking (though obviously that's subjective!).

Both are impressively well built and have excellent reliability credentials. The area that separates them is quite simply fuel consumption. The Mondoe's 2.0 TDCi engine will be a bit more usefully grunty than that Passat's 105hp 1.6 TDI unit, but the Volkswagen's engine will prove to be a lot more economical. You should be able to average close to 60mpg in the Passat, which should be around 5-10mpg better than the Mondeo will manage. To illustrate it, we once managed to drive from Galway to Glasgow, back to Galway and up to Dublin on one tank in a Passat 1.6 TDI.

Hi Ronan,

The officially quoted fuel consumption figure for the Passat B6 model with the 1.4 TSI 122hp engine was 7.5 litres per 100km (or 39mpg) combined, with the urban and extra urban figures working out at 10 litres/100km (28mpg) and 6.1 litres/100km (46mpg).

Hope that helps.

Hi Paul,

For maintenance cost questions, I'd ask your friendly local Volkswagen dealer - they'll be able to give you much more accurate information than we would. 

As for the engine, it's perfectly up to the task of pulling the car because although it's a 'mere' 1.4, it also has a turbo and produces 120hp - about what you'd have expected from an old-school 2.0-litre naturally aspirated engine. It's also pretty frugal, so if you're not planning lots of long motorway journeys, it might work out better value than a diesel.

Hi again Paul,

There were some issues with the very complex turbo-and-supercharged 1.4 engine, but the Passat generally uses the 1.4 turbo with 122hp and there are no major reported issues with that engine. 

It has plenty of poke though, so there's no lack of performance either.

Hi Roisin,

Well, it's a lovely car - smooth and comfy - and that old 1.9 TDI engine is very economical. Watch for problems with the injectors and the air pressure sensors, but otherwise it's a long-lived unit. 

The 2005-on Passat is a very complex vehicle though, with lots of trick electronics so make sure it has a full service history if you're interested in buying it.

Expert answer

Hi Joan,

We highly recommend the Hyundai i40 Tourer. It has a huge boot (though the Passat's is larger again) and is very comfortable. It's not easy to choose between the i40 and Passat at a fixed budget, so see what you can get for your money. The Hyundai, for instance, comes with a great five-year warranty from new and a high level of standard equipment. Its 1.7-litre diesel engine is also better than Volkswagen's 1.6-litre TDI equivalent, though the Volkswagen 2.0 TDI engine is better again if that's within reach.

Either way you're making a good choice and we'd recommend you test drive both cars to see which you like best.

Hi Sean,

As far as the gearbox is concerned, more is always better, so a six-speeder should help keep your fuel consumption down a bit, especially if you do lots of cruising in top gear. 

As for engines, the 100hp one you refer to is a 1.6 petrol, while the 130hp unit is a 1.9 diesel. Obviously the diesel will be more economical, as the 1.6 struggles with the weight of the Passat and also suffers from problems with its driveshafts. 

Buy carefully though, as Passats of that age have often been abused by careless owners. There's plenty about however, so you can afford to be picky.

Expert answer

Hi Barbra,

It could be. The mileage isn’t that high and, obviously, we can’t comment on the condition of an individual car that we haven’t seen, but Passats are generally well-made and if it comes with a full service history, then that’s a good start.

Expert answer

Hi Diarmuid,

There would probably be no saving at all. While the FSI engine is cleverer and more high tech and therefore technically more economical, the extra weight and bulk of the Passat will nullify that advantage. If you were to swap for an FSI Golf, you might do better, fuel-wise.

Hope that helps
