The Volkswagen Group in Ireland has begun applying ‘fixes’ to thousands of cars with 1.6-litre diesel engines which have been affected by the worldwide emissions scandal

It is understood that a “few” have already been dealt with by garages.

That marks a major step forward as vehicles with the 1.6-litre powerplants represent the largest numbers involved in the operation here.

And they are different from the other two engines (1.2 and 2-litre) in that they needed hardware as well as software upgrades.

The hardware involves fitting a new ‘flow transformer’ to help better regulate how fuel and air are burned in the engine. The 1.2-litre and 2-litre engines only need a software update.

Around 115,000 diesel vehicles were caught up in the emissions scandal in Ireland.
