Hi Jon,

At that mileage, your car is likely suffering from voltage fluctuations and ageing wiring and connectors, all of which can lead to the issues you are describing. 

I'd suggest you go back to basics and have the battery, alternator and each and every earth connection checked and cleaned for starters. Then plug the car into a diagnostic computer (any good mechanic can do that) and clear the faults before driving it and plugging it in again to see what comes up.

Some common 307 HDi issues we know of:

- Boost control solenoid
- EGR valve or position sensor
- BSI (Built-In Systems Interface) can act up with water ingress or voltage surge

In summary, there's unlikely to be a simple fix to this, but it's almost definitely electrical.

Hi Zoltán,

Those comments from the writer appear to stem from how poorly the car drives. It's summed up in this paragraph:

"The suspension in that car is soft and sloppy, which makes the car lean and lurch around corners, particularly if it has to deal with a change in elevation, direction and road surface all at once. Yet despite that, the ride is still as firm as that of a hot hatchback, with an unsettled feel over even the smoothest surfaces and a sharp thump over any potholes. Combine that with the wheelspin and slow steering that feels as detached and lifeless as a cheap games console's wheel, and the driving experience goes from being unremarkable to unacceptable."

Anyway, Jaecoo is not sold in Ireland yet, so hopefully all the teething issues will be sorted out before it is...

Hi Mary,

So long as you don't alter the seating capacity or interior in any way that might suggest the van is used for passengers, it shouldn't make any difference to the classification of the vehicle. It might be worth informing your insurer as it's a modification.

Hi Stephen,

To be honest, there'll be a huge gulf between the cars because they're 14 years apart. Your Citroen's suspension and bushings etc will be quite worn, no matter how much work it has had done, while the Dacia will feel tight, rattle-free and sharp to drive (in a good way). The Bigster will have far superior road holding where the Citroen feels 'loose', though the latter could mean more comfort in some circumstances.

The Bigster's steering will feel more responsive, as will the brakes and the engine. The Bigster should have superior wind and road noise suppression and with brand-new tyres it should be better in wet weather as well.

Finally, the Bigster has all the latest driver assistance technology that is vastly superior to that of your Citroen, in theory making it a safer car.

Hi Gary,

Not really, though the Auto setting for the four-wheel-drive system does send all power to the front wheels unless it deems it necessary to send some to the rear. It effectively is in two-wheel-drive mode most of the time.

Hi Niamh,

We'd never consider those cars to be rivals as the Kodiaq is so much larger inside, but if that's your shortlist, we can work with that.

The Kodiaq is a lovely car, but the RAV4 has the edge in terms of reliability. The Skoda isn't inherently unreliable, but Toyota has an exceptional reputation in that regard.

Nonetheless, I highly recommend you go and test drive both cars for as long as possible, as they drive in a hugely different manner. No point a car lasting forever if you don't actually like how it drives.

Do let us know how you get on.

Hi Teresa,

There's no definitive answer to that, but let's talk through some of it.

First up, while three-cylinder engines might be less balanced and more susceptible to stress when pushed than their four-cylinder counterparts, that's entirely unimportant if you generally pootle around and don't extend the engine to its fullest. And you service it properly.

If you like your car and you don't have to change it, why bother? The more you change your car, the more it costs you in the long run after all.

Nonetheless, if you've got it in your head that you don't trust the three-cylinder engine for some reason, then both the 1.5 Golf and the Corolla are good options.

If all that matters to you is reliability, then it's hard to ignore the Toyota as it has such a strong reputation on that front. We wouldn't expect the Golf to be unreliable as such, but the Corolla is bombproof.

But there's a lot more to a car than dependability and if you already like the Golf, you may well prefer another one over the Corolla. The drive very differently and feel very different, too.

Our advice would be to go and test drive the cars for yourself to see which you prefer, but don't hurry into a decision if there's nothing wrong with your current car.

Hi Cathal,

We'd be fools to suggest that you can be 100 per cent sure you won't have a problem if you do x, y and z, I'm afraid as there's just no guarantees with DPFs.

Saying that, modern cars such as the Tucson and Octavia you mentioned have way better DPF regen logic than they used to, along with more sophisticated exhaust monitoring than before so that's a good start, as is knowing the type of driving that's needed for diesel cars with DPFs – as you've indicated you understand.

You could ask the dealer selling the car (assuming you're not buying privately) for a diagnostic readout with the DPF information, but they're under no obligation to do that and some may not even know how.

My advice would be to insist on a detailed service history, scrutinise that for anything related to the DPF, then ask the seller if any work on the DPF has ever been done. Finally, take it for a decent test drive and, if possible, get someone else to drive it while you follow to observe the exhaust for any excess and obvious regen activity. You may see nothing with such modern cars, however.

The key thing here is to only buy a DPF-equipped car if you spend a portion of your normal driving at higher speeds, allowing the whole exhaust to get hot and work effectively.

Hi Rohit,

Browse one of the big car classifieds to find as new a version of the Tesla you have in mind as possible. Use that car's registration to obtain the insurance quote. It may not be exact, but it will give you a good feel for what to expect. It's likely your insurance will go up quite a bit as I'm sure you know.

Hi Harvey,

I'd thoroughly recommend the Volkswagen Multivan for your needs. It comes in two lengths with seven seats. Both are highly versatile, and the boot is big even if you're using all the seats, especially the one with the “long overhang” body.

We've taken this car away on long holiday trips and it has been nothing short of phenomenal. We're only a family of five, but we all fitted in comfortably as well as a few bikes and way too much stuff for a couple of weeks away camping.

What's more, there are diesel and plug-in hybrid versions available, depending on your needs, and it drives more like a car than any of the actual van-based people carriers out there.

The Tourneo would do the job, too, but it's not as flexible and nowhere near as nice to drive.

Go test drive one for yourself and let us know what you think.
