Hi Paul,

I can't tell you as you won't get a final figure until you bring it to an NCT centre for assessment, and Revenue will give you the cost of the VRT. Anything I tell you is mere speculation, but if you want a very vague ballpark figure, a 2014 Optima will probably be judged to have an Irish Open Market Selling Price (and that's what Revenue will base its assessment on, not the price you pay in the UK) of around €24,000. With 136g/km CO₂ emissions, that means you're in Band B2 for tax, so that means 19 per cent of OMSP, which works out at roughly €4,500.

But, please, don't take my word for it...

Hi Una,

The 2010 1.5 Mazda2 has CO₂ emissions of 135g/km, so that'll be Band B2, and motor tax of €280 a year.

Hi Dave,

The Land Cruiser is indeed getting a new 2.8-litre diesel engine, which is claimed to be nine per cent more efficient than the old 3.0. It has CO₂ emissions of 194g/km, 177hp and 420Nm of torque. Shared with Fiat though? No - Fiat does have its own 2.8-litre diesel, but it's a commercial vehicle engine, usually used in the Ducato van. For its passenger cars (Jeep Grand Cherokee, Maserati Quattroporte, etc.) the Fiat group uses a VM Motori built 3.0 V6 diesel.

Hi Ola,

That depends on what year it was registered. If it’s an original Irish car registered before Jan 1st 2008, then it’s on the old engine capacity tax system and will cost €710. If it was registered after 2008, or is a UK import brought into the country since then, it’ll be on the CO₂-based tax system and, with CO₂ emissions of 198g/km, it’ll cost a whopping €1,200.

Hi Shane,

We enlisted the expert assistance of Conlan Crotty Murray & Co (Leopardstown, Dublin 18, 01 295 9090, www.conlancrottymurray.com) to answer this one for you. Here's the response:

"Generally speaking, leasing companies will only lease new cars.  On the basis that the individual decides to lease a new car then the rental payments under the lease agreement should be treated as an expense in the accounts of the self-employed individual.  As the lease period is usually three or four years this provides for a significantly accelerated write-off of cost for tax purposes as compared with the purchase of an owned vehicle where the tax write-off under the capital allowance regime is spread over eight years.  However, at the end of the lease period if the vehicle is traded in against a new vehicle the trade in allowance on the first leased car may trigger a claw-back of lease charges previously deducted for tax purposes. 

To the extent that the individual uses the car for private use in addition to business use then an appropriate restriction on the tax deductibility of the leasing charges should be applied. E.g. if the car is used 40 per cent for private use, then 40 per cent of the lease payments should be disallowed as an expense in computing income for tax purposes.  The benefit-in-kind provisions referred to by the reader do not apply to self-employed individuals.  The benefit-in-kind rules would apply to the extent that a leased car is provided by an employer to an employee in computing the employee's payroll tax liability.  There is no private use restriction on the tax deductibility of leasing expenses for a car where the car is supplied to an employee and that employee uses the car for private purposes.

Some of the annual lease rental expense may be clawed back in the computation of income for tax purposes if the car has a retail value at inception of the lease of more than €24,000 and the CO₂ emissions from the car do not exceed 155g/km.  If the car has CO₂ emissions of more than 155g/km, but not exceeding 190g/km, the value of the expense deduction for income tax purposes is restricted by reference to a reduced capital limit of €12,000.  Where the CO₂ emissions on a car exceed 190g/km, no deduction for leasing costs is permitted in calculating the individual's income tax liability for the year.

Therefore, for new leased cars costing no more than €24,000 with CO₂ emissions not exceeding 155g/km the lease payments may be written-off against income tax over the course of the lease period.  

We recommend that professional advice be sought before entering into any lease arrangement."

I hope that clears it all up for you Shane.

Hi Pat,

The dealers are, in fairness, being evasive because they don't have the full picture yet. None of us do, to be honest. However, there's no really good reason for not buying an A6. It's an excellent car, very frugal and lovely to drive, and beautifully built too. If it does turn out to be one of the cars on which the CO₂ emissions and fuel consumption has been under-estimated, then you will be compensated for any gap - Volkswagen Group has promised that customers will not be out of pocket as a result of all this. So I'd say go ahead - cracking car.

Expert answer

Hi Martin,

I'd say you should advertise it for around €6,000 all things being equal. As for the diesel controversy, it's a bit hard to say - there's nothing at all wrong and an awful lot right with the 2012 Passat - it's a cracking car, it's just that you need to bear in mind that the overall engine performance may well be altered when Volkswagen begins its recall in January. If that's putting you off, then a Mondeo is definitely well worth looking at, but also take a gander at a Mazda6, Opel Insignia or Hyundai i40.

Expert answer

Hi Niall,

We asked Ford Ireland about this for you. First of all, it was confirmed that your car has a timing belt, not a timing chain.

With regards to the injectors, a longer response was given:

"Mondeo DV6 has a Continental fuel system and the fuel injectors fitted on this system have correction factors on them. What this means is that they have a unique ID number that the engine's PCM need to know so it can operate them. The pump has nothing to do with how the injectors operate and its role is simply to bring the fuel up to the high pressure demanded by the system. When an injector is replaced the PCM needs to know the new number of the injector installed. This is inputted using Ford IDS Diagnostic tool. If the injector is installed and the correction factor is not learned using the Ford Diagnostic tool the vehicle will not run at optimal level and the engine may exhibit excessive noise and emissions."

Finally, with regards to a shaking steering wheel, that could be something as simple as a wheel going out of balance, so check that before you consider changing any brake items. Whether the dealer should replace warped discs after six weeks is not so clear - it really depends on the terms of your warranty.

Hi Philip,

Not all marques and not all models use AdBlue as yet. AdBlue is a urea solution that can be injected into he exhausts of diesel cars to neutralise a significant proportion of their emissions of nitrogen oxides (NOx) - very much in the news at the moment of course. The rule of thumb is generally only that larger, more powerful engines need an AdBlue treatment system as many smaller engines don't need the assistance. Each manufacturer, and indeed each individual engine, will have its recommended AdBlue top-up times, and it will be directly related both to mileage and how much acceleration the car has been doing. You can top up the AdBlue tank yourself - a 1.5-litre refill should cost around €11-12.

Expert answer

Hi Gary,

Volkswagen has confirmed that, following investigations, the EA288 engines, designed for EU5 and EU6 compliance, are not affected by the scandal surrounding the EA186 engines. In other words, the current Volkswagen diesel engines are fine and have been given a clean bill of health.
