9-5 Aero failure – follow up.

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).

Greg’s posted a picture of the gauge installation in his 9-5 Aero here. The other common install is via an aftermarket pod on the dash or the A-pillar.

  1. I really like Greg’s setup. Not only do you get the gauges but also gives you an excuse to get new radio! Is the bracket an after market item or did Greg custom make it?

  2. I imagine Greg will be checking in, so I’m sure he’ll be able to post some details.

    Just guessing, but it looks like the removal of the standard radio left two DIN sized holes, which brackets should be readily available for.

  3. The gauge installation itself is not difficult. Saab Europe sells a cage which separates the stock radio spot into 2 DIN sized holes. I bought it at genuinesaab.com – URL:

    The real trick is installation of the new head unit. The Aero has the HK stereo, and the stock head unit sends a “balanced signal” to the stock amplifier – apparently there’s a lot less signal loss in this set-up. The problem is that nearly all aftermarket stereo units don’t use this type of signal – and I had to get a “line driver” to convert the standard output of the new head unit to the balanced signal expected by the stock amp.

    Now that the installation is done, it sounds very good. Cleaner and crisper than the stock head unit. Much better bass.

    Overall I’m very pleased, although the hassle factor of dealing with the radio installation in order to get the gauges in the dash was pretty high.
