They just keep on going don't they.

With the help of a little TLC along the way. mechanical & corrosion prevention.

I had two Saab passes this month, plus a pre test on a family related Peugeot 108. I predicted two advisories. There were two advisories, from Kwik Fit no less, one day after the MOT expiry date  ::)

New tyres this week, a complete set of Michelin Crossclimates, 235/45 R18 98Y XL for £592 fitted at Costco. I had to get these on short notice as I had got lazy with checking tread depths as ideally I should have replaced them a few months ago really as one of the fronts was borderline on getting me 3 points... At least now the weird handling issue has gone.

Other jobs I need to complete soon are put the ECU heat shield on as it's been sitting in the boot for several months, I also have a spare engine ECU from ebay which has also been sitting around for a few months. I have all the tools to take a copy of the current software and will put it on this spare and test it, I just hope it's OK but that's on me for not testing it as soon as I got it.

I also had a weird fault code the other day (P1682 ECM - Plausibility Fault between voltage feed from +15 and main relay) so need to clean up the earth points at a guess although this could be ignition switch or something else, I also have some new door speakers to fit but I want warmer weather first as I'm recovering from flu and coughing a lot.

If this is a T8 ecu this sometimes appears when the ecu is about to go/gone south..

I'm aware of that, it's why I have the spare ECU sitting around although this code has been randomly appearing in the car since I got it 18 months ago with no signs of it getting worse.

We had some snow yesterday,more today & the forecast suggests we are going to have an extended cold period

Time to swap onto the Winter tyres / Insignia rims on the 9-5 TTiD.

All done, pressures checked, much improved grip levels, so I can tackle whatever the weather throws at me  :Fawlty:
