Hi Tony,

The second-generation Octavia launched in 2004, which means you're most likely looking at two completely different generations of the model. There will be some small number of parts potentially shared across both, but not a lot at all, especially as the engines are also different.

Hi Pat,

We certainly have noticed this trait in all Volkswagen Group DSG-based gearboxes (that's what the S tronic transmission is) and their attendant engines of late. The only explanation seems to be that VW’s various brands have trimmed back both engine power and responsiveness at low speeds, and especially at idle or when waking up from a stop-start cycle, in order to optimise their figures in the new WLTP emissions and economy tests. VW is certainly not the only one to do this, but it does seem to be more obvious with VW Group models than with some other manufacturers. Shifting the gearbox into Sport helps a bit, but it’s not a total fix.

One cure might be a total vehicle upgrade — we’ve noticed that the new ‘Evo’ versions of the 1.5 TSI petrol and 2.0 TDI diesel engines are noticeably less sleepy. Or, alternatively, trade in for a version with a manual gearbox — that is the simplest cure of all.

Hi Leigh,

It depends on the engine. There's a timing chain in the 1.6, 1.8, 2.0 and 2.4-litre petrol engines and a timing belt in the 2.0-litre diesels. The 2.2 diesel, which only went into production in 2005, has a timing chain.

Hi John,

That's kinda a 'how long is a piece of string?' question, as no two engines are created equally. I mean, every different 1.6-litre diesel engine has a different realistic life span. And while it's reasonable to presume that a diesel engine is designed to be driven over higher mileage, I don't believe that manufacturers aim for 'worse' durability for their smaller petrol engines.

Hi John,

All engines fitted to the 131-generation Toyota Avensis used a timing chain, not a belt.

Hi Kris,

The problem is that Irish insurers are a bit blunt-force when it comes to deciding their rates, and generally speaking (and completely erroneously) they simply tend to go by engine size. So even though there are plenty of older 1.9-2.0-litre diesel engines with similar power outputs to a more modern 1.6, they’ll probably quote you more just because it’s a bigger engine. Stupid, but then that pretty much sums up the insurance industry in Ireland. All I can suggest is either biting the bullet and getting a 1.6 that maybe you’re not as keen on, or finding a really good local broker who can help you track down quotes that us mere mortals can’t find.

Hi Joe,

It’s actually €710, the rate for cars with engines sized between 1,901cc and 2,000cc (the Amarok 2.0 is actually 1,968cc). As we’ve said before, for some bizarre reason, if you’re taxing a commercial vehicle as a private car, you go back onto the old by-engine-capacity system.

Hi Colin,

Yup, Mercedes will be bringing the CLA 220 and CLA 250 diesel models, with their 2.0-litre engines, to the market in due course, but the CLA is launching initially in Ireland with the lower-power petrol and diesel versions. The rest will follow over the next few months.

Hi Timothy,

The timing belt on the 1.5-litre dCi diesel engine (and hence the water pump) should be changed every 150,000 kilometres or six years - whichever comes first. If the belt on that car has never been changed, it really should be as soon as possible.

All other engines in that car use timing chains, incidentally.

Hi Peter,

The A16LET engine is a 1.6-litre four-cylinder turbocharged petrol unit according to our records, producing 179hp and manufactured from 2009 to 2014. 

If your engine is pre-2010, the recommended change interval is 150,000 kilometres or 10 years, whichever comes first. For engines made after that date, it's still 150,000 kilometres, but the maximum time between changes is six years.
