Hi Steve,

This is a really tough one and it's unlikely to be a simple answer. The integrity of the head gasket relies on so many other parts of the engine, such as the flatness of the cylinder head and the torque applied to the cylinder head bolts. It would be very difficult to prove any wrongdoing by the garage that originally fitted the part.

For the same reason, it's highly unlikely that that would give any guarantee on such work. It's just not the done thing.

I'd suggest you go back to talk to them and try to come to some compromise. When you do have it done again make sure you insist that the cylinder head is skimmed and that you get a receipt for that work. It may also be worth suggesting that the cylinder head bolts are inspected, as some manufacturers require these to be replaced, which a garage may not automatically do.

I hope all that helps. Come back to us if you need to know anything else.

Hi Andrew,

According to Ciaran Allen, Sales Manager of Mercedes-Benz, "Stop/start is the main factor in reducing CO₂ and is available now on manual models. We are not expecting full availability on stop/start including seven-speed auto until August production - September arrival. Because of our market seasonality August and September are not big production months for us, so while it will be available we really consider E-Class seven-speed as a 2012 car. The model price won't be reduced but the auto road tax will go from band C to band B."

Hope that answers your question?

Hi Susan,

While our service is predominantly designed for an Irish audience, we don't minding answering the occasional question from abroad. Your valuation would depend on several other factors though:

• Is it a 2005 or 2006 car?
• Which trim level is it?
• Is it manual or automatic?
• Is the specification standard or are there desirable extras?

If you can let us know those details we should be able to give you a more accurate estimation.

Thank you

Hi Frank

The dual manual you refer to is I am guessing a DSG or double-clutch gearbox and we are certainly fans of them here at CompleteCar.ie. They have been around for quite some time now and therefore most of the major problems appear to have been ironed out. They offer a smoother auto change than a standard automatic transmission, plus they will behave like a manual (without the clutch obviously) if you want them to.

Something like this would be a lovely car.

Hi John, 

According to Hyundai, "The 2.0 CRDi automatic features an all-new six-speed self-shifting transmission that is smaller and lighter than any other six-speed automatic offered anywhere in world.

As well as the obvious economy and emissions benefits, the system uses a uniquely-shaped torque converter to reduce its overall size, and features three planetary gears and four pinion differentials.

Although it offers smooth and precise gearshifts throughout the rev range in fully auto mode, the gearbox can also be used like a sequential six-speed manual. A gate-type shift pattern allows the driver to choose between fully automatic or clutchless manual ‘Sport’ modes, which offers even more driver involvement and a more rewarding driving experience beyond the city limits."

I hope this helps.

Hi John,

It was developed in-house by the Hyundai-Kia Group for fitment in a wide range of future vehicles. It is a six-speed unit. The driver can choose from two operating modes - fully automatic or ‘Sport’.  For city driving, fully automatic mode is ideal, while ‘Sport’ mode allows for clutch-less manual gear changes for greater driver involvement - either using the centre console selector lever or the new steering wheel-mounted ‘paddles’ (standard on all automatic models). 

The paddles  enable the driver to change gear without taking his/her hands off the steering wheel.  Pulling the right-hand paddle towards the driver changes ‘up’, while pulling the left-hand paddle changes ‘down’.

Although the six-speed transmission is a regular ‘torque converter’ automatic, it incorporates a unique ‘flat’ torque converter, with three planetary gear sets and four pinion differentials - ensuring, according to Hyundai, ultra-fast, smooth and precise gearshifts throughout the engine speed range - and it weighs just 78kg - 20 kg more than the manual gearbox.

Its layout makes this transmission the most compact six-speed unit currently available anywhere in the world according to Hyundai.  It is 54 mm shorter and weighs 12kg less than a regular five-speed unit and boosts fuel economy by up to 12 per cent.  Like the i40’s six-speed manual, the automatic is a ‘filled for life’ maintenance-free unit. 

Automatic transmission-equipped i40s will feature cruise control and Hyundai’s ‘Active Eco System‘ economy indicator to assist with fuel-efficient driving.

Hope that's enough information?

Hi Niamh,

We spoke by e-mail and now I have a better idea of your budgets there are a few good ideas. I think the Ford S-Max is probably my favourite car of this bunch. I quite like this one. It is diesel, looks great and has low mileage. We reckon you could get them down in price a little too. 

In relation to the choice between manual and auto in the C4 Picasso, that really is down to personal choice. It isn't the greatest auto ever but it isn't the worst either. You really should try it and see. The EGS box is a little jerky. Personally I wouldn't really fancy it but you should be the judge. This one is quite nice and has really low mileage. 

I wouldn't say not to consider Renaults, but they weren't a good vintage at the time, so personally I don't think I would be spending money on a 2007/2008 Scenic. They have got a lot better since then though. 

Lastly, you could try a VW Touran. It isn't that exciting but they hold their value really well and are nicely built. 

Anyway Niamh, if it were my money, I'd have the Ford S-Max.

I hope this helps.

Hi Justin,

Overall, that's a nice, comfortable, quick car, which isn't too bad on fuel. The four-wheel drive and automatic gearbox make it less economical than a manual, front-wheel drive car, but you probably want those things so that's irrelevant. The equivalent BMW will be more economical and in our opinions better to drive.

However, the Volvo excels at being comfortable and spacious and of course it's crammed with safety equipment. The 2007 D5 engine is powerful, but a little louder than those in rival cars.

In terms of reliability, this generation of S80 was subject to a few relatively minor recalls, though the issues would annoy you so make sure any car you look at buying has had these rectified.

If you'd like to know anything else specific, just get in touch.

Hi Tom,

Is this a new or used car you would be buying? A new Toyota Yaris comes with the MultiMode transmission and a 1.3-litre VVTi petrol engine, which will cost you €18,285.

A Mitsubishi Colt automatic with a 1.3-litre engine will cost you €15,450 and that is quite a bit less. 

A Ford Fiesta 1.4 Style Auto would come in at €18,735 and this would be a really nice car. 

The best bet for us would be a Hyundai i20 1.4 Deluxe Auto, which comes in at €16,995 and that is a super little car. If it is a straight choice between the Yaris and Colt I think I'd save the €2,835 and have the Colt. 

Come back to us if you're buying second-hand, as the story may be a different one.

Hi William,

The official fuel economy figures for the 520d manual and automatic are as follows. The first figure in each case is for the manual model and the number in brackets is when fitted with the eight-speed automatic with Steptronic.

Fuel Consumption in EU Cycle

Urban: 

5.9 (6.4) l/100km

47.8 (44.1) mpg

Extra-urban:

4.3 (4.5) l/100km

65.6 (62.7) mpg

Combined:

4.9 (5.2) l/100km

57.6 (54) mpg

CO₂

129 (137) g/km

As you can see there is very little difference. As regards the M Sport model, we don't know how the new version of the 5 Series M Sport rides as yet, but I collect one this Tuesday so I will come back to you on how it drives then.

I hope this helps,
