I have been told that campaign 0953, a software update, needed to be performed on my new ISL 425 powered coach. Anyone know what that update is all about and how urgent it is to perform? It may be several weeks before I can get it done. Thanks.

I had an issue with excess crankcase pressure on a 09 Allegro Bus which resulted in having to be towed in and they replaced all valve guides. From what Tiffin advised this was the software change that was suppose to prevent the turbo from overboosting the engine, anything else beyone that I don't know. I just had it done couple of weeks ago.
