Hi John,

As discussed via email, you need to determine that a) the electric fuel pump in the tank is working and b) that fuel is getting to the engine. These are intricate jobs that only a qualified mechanic should attempt. Given that your car was rear-ended, it's highly likely that the issue is related to the fuel pump in the tank.

Failing all that get an auto-electrician to go through the relevant fuel pump relays and fuses.

Hope you get sorted.

Hi Justin,

Let's break it down into chunks. First of all, safety. Here are the crash test results from Euro NCAP:

Skoda: five stars on new system

Saab: five stars on old system

Volvo: four stars on old system

Looks like the Volvo loses out there, though it's a safe car by most standards.

In terms of reliability, the Skoda has no reported issues. The Saab doesn't fare so well, with plenty of electrical issues and problems with the suspension. Check for uneven tyre wear and that all the switches are working - every single one. The Volvo is a little better, but has a few known problems, with random electrical gremlins and several recalls. If you're serious about that one get confirmation that the recall work has been completed. Also, it should have its timing belt, tensioners and pulleys changed every four years so best to check that it has been done.

Assuming you're looking at the 105hp Superb, then the combined cycle consumption was quoted at about 5.7 litres/100km (50mpg) and it is a frugal car. The 150hp Saab uses a fraction more fuel (5.8 litres/100km) on the combined cycle, while the 136hp Volvo also uses 5.7 litre/100km.

So in summary, for us it would be between the Skoda and the Volvo. They're both comfortable and spacious, though we'd trust the reliability of the Superb more given the data.

Hope that helps.

Hi Linda,

Honda undoubtedly has an enviable reputation for reliability, but the 5 Series BMW is one of the company's most reliable models. The current generation has only been in production since 2010 so it isn't old enough for us to have a lot of reliability data as yet, but its predecessor fared very well with only a few minor issues and electrical faults early in the model's life. It has since proven to be very robust. In terms of the engine, the BMW's 2.0-litre diesel has been around for a while and is made in large numbers, so there's nothing to worry about there either.

With my own money there's no doubt I'd go for the BMW.

Let us know what you end up doing.

Hi Paul,

Well one obvious answer, given the length of your commute would be to charge it in work during the week. Failing that, while the ESB will fit a box to the outside of your house, this would mean a lead being attached to your car from this and this of course could be open to vandalism. You will find that the number of on-street charging posts will dramatically increase over the next 12 months and there may be one near where you live with a special parking spot for an EV.

Hi John, 

The Atkinson engine is a type of engine invented by James Atkinson in 1882. The Atkinson Cycle is where the stroke of the piston can very in length across the four cycles in a four-stroke internal combustion engine. The length of the stroke during the power cycle is increased to promote efficiency, but because this comes at the expense of a shorter intake stroke there is some loss of power and therefore this engine design is best suited for use in hybrid systems where the electric motor can make up for some of the loss of power. 

In conventional four-cycle petrol engines, fuel enrichment is sometimes necessary to cool the exhaust gases, preventing degradation or destruction of the catalytic converters. In an Atkinson cycle engine, compression and expansion are not symmetrical, and the valves close late, delaying compression. This creates a high expansion ratio for less compression, reducing intake and exhaust energy losses and converting combustion energy to engine power more effectively. As a result, the exhaust temperature is lower than that of conventional engines.

The current model Toyota Prius Hybrid uses a 1.8-litre Atkinson Cycle engine. Adopting the Atkinson cycle and a cooled exhaust gas recirculation system brings significant gains in fuel efficiency and emissions reduction.

Prius 1.8-litre Atkinson Cycle engine

Because the intake valves close late in an Atkinson cycle engine, compression is delayed. This creates a high expansion ratio for less compression, reducing intake and exhaust energy losses and converting combustion energy to engine power more effectively. As a result the exhaust temperature is lower than that of conventional engines. Cooled Exhaust Gas Recirculation reintroduces the cooled gas into the intake system, further reducing engine operating temperatures.

Other models to use Atkinson Cycle engines include the Lexus CT200h, Lexus RX 450h, Mercedes S400 Blue Hybrid

Hi Gar,

We are never short on opinion here at CompleteCar.ie Gar, so you have come to the right place. Coming out of your 5 Series you are going to have to buy something that is vaguely interesting or you are going to really hate whatever you buy. Given that you are concerned about reliability you are right to express some concerns about the Passat. Unfortunately there have been quite a few issues with the last model Passat and it would probably stop me buying one second hand, even though it is usually the default choice. I'm not sure why you mentioned the Rover 75, but lets pretend that you didn't.

If I was buying something with €8,000 - €9,000 I think it would probably be a Mazda6 Diesel. I really like them and they age really nicely. 

Here is a decent example: 

You would have to check the DPF is ok, but otherwise they are a cracking good car.

Hi Tariq,

Given that these cars would both have electric seats with a full range of motion, your height will not be an issue. Perhaps the Range Rover would provide better visibility.

Either way, your height shouldn't be any sort of factor in what car you choose as most are designed for a wide range of driver sizes.

Hi Jim,

Personally I have never really been a major fan of the footbrake on the Mercedes-Benz cars, but I wouldn't say that they are hard to manage. They just take a little while to get used to. It certainly wouldn't be a reason not to buy one

The electronic handbrake on the BMW has been very reliable so far, but they again it hasn't really been around long enough for any major problems to surface just yet.

Hi Linda,

It certainly does sound like an injector issue - assuming the coil and plugs are fine. We'd suggest that the injectors are tested before hastily replacing them. Any decent garage will do that for you - it doesn't have to be a main dealer. From the information you've given us about the car, we don't believe you can re-program the injectors. It may be possible to refurbish them, but in most cases it's probably better just to replace it.

If that's what is needed, the cost of the part itself is well over €100, but no garage should charge you more than an hour of labour for replacing it, as it's a relatively easy job.

Hope that helps and you get sorted.

Hi Michelle,

With a car of this age it's not surprising that something may have worn out. Without knowing the mechanism of the 306 CC in depth we would never hazard a guess as to where the problem lies. Without doubt your best bet is to bring this into a Peugeot dealer to get their opinion. The service manager may know of a common problem and quick fix so talk to them before committing to any work.
