I’m sure Fransisc would echo my thanks to all who contributed their experiences and knowledge after reading about the catastrophic turbo failure in his 9-5 Aero. Amongst the comments there’s a few things that I think are worth noting. There might be something here for 2.3 owners to think about and act on.
Firstly, it seems that maybe the standard warning system for the 2.3HOT isn’t always up to the task of providing adequate information in a timely manner. I’m counting all 2.3 applications here, not just the 9-5 Aero. There’s several testimonials there that give me cause to think that either the switch can malfunction or provide it’s warning after the horse has bolted.
Greg makes a good suggestion, I think – he’s added oil pressure and temperature gauges to his 9-5 Aero, which is something that I’ll seriously consider if I get my Viggen back in one piece. If I don’t, then a 9-5 Aero may well be on the shopping list and again, this is something I’ll be looking at.
Of course, nothing beats regular visual checking of your oil levels and replacement at appropriately short intervals (I do mine every 5,000km).
