Had the software update done by the AA on behalf of Volkswagen. Since it was done, my Volkswagen Caddy Maxi has gone into limp mode with an apparent EGR valve problem. Volkswagen told me categorically this had nothing to do with the update (sceptical to say the least) and that I am facing a bill of about £1000. All this without even seeing my vehicle. Spoke to customer services who are contacting the dealership about this and their inability to offer a courtesy car for at least two weeks. Also the EGR valves are on back order with no news of when they will be in, suggesting a run on them since the recall started. My advice to anyone who hasn't had the update is don't. No one will admit to there being a connection, whereas anyone looking at the internet can see that there is. Wish I'd looked beforehand as I wouldn't have gone ahead with it.
