Should I get the emissions update done on my 100,000 mile Skoda Suberb?

I own a 2009 Skoda Superb. It runs very well, done 110,000 miles and I plan to keep it. Skoda have invited me to bring it in for emission software change, assuring that there will be no change in fuel economy or power. The next service is not due for some time. Having read your replies to various queries on this, I am minded to wait till the next service, or even not have it done then. What do you think?

By 110,000 miles the injectors will be worn, the EGR valve stem will be worn and the DPF will be filling up with ash (and is soon likely to cause problems anyway). The NOx emissions fix involves a more complex injection cycle that imposes more work on the injectors and the EGR so if they are already well worn the engine will probably have problems. If the dealer guarantees to replace any worn parts, then okay to go ahead, but he is highly unlikely to, and you could be faced with post fix bills of up to £2500 for a new EGR and new injectors.
