Took the black 2006 Dame Edna for an MOT

The tester remarked that I did a lot of miles in her, as he checked the MOT history. Then he gave me a clean ticket

Now you will never know what solved the problem....

Funny.... having seen the agricultural engineering approaches to ripping open a hole in the 9-3 floor to get access to change the pump, I was wondering "what about getting a 9-5 cover plate (perhaps with part of the 9-5 floor) and spending the money on doing what Saab should have done in the first place".

Or you could just put a 20 ohm resistor in series

Ah, fair point, it's the first to move to move away from traditional FI type design to the newer direct injection, like the NG 9-5's

You're right about the damped fuel gauge response, you can see that by filling up a car with fuel while its idling because you have grave concerns about the battery or something else. Seen that.

Question is, does Tech 2 give access to both sensors, or is it the combined damped output response. One way to find out.

Can you put the pump into a permanent live situation ?

That way you can circulate your treated fuel without actually consuming any, and perhaps even graph the fuel pressure at the same time.

I would have the charger onto the battery, to maintain state & not drag your new one down...

Did you pick up from WIS that the P00089 code is also triggered by running out of fuel, or at least the car thinking you have run out of fuel...

There's what looks ike a decent diagnostic in WIS, but it does assume you have access to the tank

Buried away I see that for EU empty is supposed to be 250 ohms, full 40

You could try applying 12v in the appropriate places to measure the voltage the ECU would see - seems to be operating on 5v due to a 487 ohm resistor though. An idea anyway

Thinking a little more, it might be worth taking readings from the ECU before you fill up.

You'll have two data points that way

I have looked again at WIS and the wiring diagrams.

Connector H10-3 "should" be visible and possibly testable, depending on location.

While searching for a photo or something to assist, I came across this https://www.youtube.com/watch?v=_5eOlhrC-gM which may be of interest. At least it doesn't have images of the rear seat floor being cut to get access to the pump. Final comment may be of interest.

Perhaps the best route forward is to fill the car up again (to replicate the problem) and then measure the readings at the ECU connector. At least that will be accessible which will allow you to get a reading for both sensors.

Interesting that the EU and US markets appear to have the rheostat wiring reversed (if you believe WIS). Intuitively it seems NG9-3 is incomplete, the NG9-5 is considerably worse, I can't even find preload settings for the TTiD turbo, which is something I may do a thread on later

, and it showed that a lot of the plastics are now very brittle. 

That reminds me of testing for current on the auto gearbox on the 9-5. I have found that with some WD40 and the right size screwdriver in the groove at the top of the red securing clip these connections do usually give in to gentle persuasion.

I suppose the alternative is to measure the values at the ECU.... but of course if there is a problem, you then need to disagnose where, and while you really don't want it to be in the loom, the alternative seems to be a tank out job

Well, another 250 miles on the car and what a difference small changes can make.

I am used to feeling the difference between  20' toe out and 10' toe in, but didn't expect to feel it so strongly on the road. The centering of the steering wheel (which means centering of the rack) has resulted in the adjustable power steering working properly, and feedback is more direct. Handling is much more similar to the 2.0 petrol as well, with better ability to carry speed round corners and the transition from a FWD bias to RWD under power more evident.

Immediately, whether due to the wheel alignment (reduction in scrub), non distorted discs causing some pad dragging, or simply she's getting used to more frequent driving cleaning the system/combustion chambers out, today's journey had me up at 43mpg, rather than the 37-38 for the same journey last week.

That's more in line with prior expectations, happier than yesterday 

The trip computer can't do maths though. Last week a full tank was apparently good enough for 360 miles, and it stayed like that until less than 3/4 of a tank was remaining. This week it showed 480 miles, when the reality last week for a tankful was more like 580, this week 660

Pump the tyres up above normal pressure and they should be OK

Let them deflate & be flat against the floor and there will likely be a permanent vibration in the future

What I would describe as strong money at £14,750 , and the car doesn't have Drivesense or Harman Kardon sound system.

Does look tidy though

I think Will has a coupe of issues on his car. Fancy sorting them out for him while you are having a good day
