New Saab 9-5 (2010 on) / Re: 9-5 NG Rescue project

« on: 16 April 2024, 05:32:32 PM »

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

Sounds like good news. Almost reminiscent of a 1970's air cooled VW, except much easier to fix

I would dry it out and then use tissue paper to try to identify the source of the water, allowing for wicking.

Did you check that the door window was all the way up, and in the correct place?

In the 10 days since the MOT I have done over 700 miles, so some impressions:

Not as quick or responsive as the 2.0T. In a sense that was to be expected, but the TTiD does allegedly have 400 Nm compared to 350 Nm in the petrol car. Somewhat the reverse experience of the old 2.2 TiD tractor engine in the 9-5 where with a lowly 120HP she was remarkable quick, with loads of torque.

Speaking of torque, there really doesn't seem to be much below 1500 rpm, though in higher gears she will pull from those speeds, so perhaps this is a"by design" mapping feature. I don't think there is a problem as there are no DTC's registered. Wish these cars had OpenSID so I could see more of what is going on. Hooking a laptop up to see the live information on boost / torque isn't really a great idea for busy A roads. 

The gear ratios seem quite sensible, 2nd may be a little low, and with 33mph / 1000 rpm in 6th I was hoping for good fuel economy. It seems at motorway speeds, I'm likely to see 37-38 mpg, which is less than hoped for and quite a lot less than the old 2.2 where on a run I could easily get above 45, so long as the speed wasn't too high.

Handling wise, this non Drivesense equipped 2011 car is quite different to the 2010 Drivesense Aero. Both are on H-arm suspension, AWD, 19" turbine rims and lowered suspension so should be comparable. I have read that Saab received feedback on the original cars and they responded to hard ride criticism by putting softer springs/dampers on. I have to say, I can feel it. The 2011 car provides much more traditional feedback of what the car is doing, whereas the 2010 car is certainly more sporty, suffers from very little roll, yet has high grip levels but fails to communicate with the driver what exactly is going on, except when it gets a bit twitchy, which it can do.

I have just had the front wheels balanced, fitted new front discs / pads to get rid of the braking vibration and andusted the front end wheel alignment so that the steering wheel is aligned and toe-in is correct. The latter adjustment is no doubt down to small differences in the dimensions / position of the subframe compared to the original. Wheel alignment went from 20' out to 10' in. We shall see this week if the new suspension settings make the handling any different.

I'll put the investigation on hold for a few days.  As the level sensor only fails to read when the tank is over ¾ full, I planned to check a reading at the connectors behind the left hand headlamp.

Seems to indicate that one of the rheostats has dead spots at the top of the range ??

I was thinking along the lines of two independent failure modes, but from you decription, but perhaps the main one is nothing more than an irregular sensor result.

From reading around, it seems that this issue does only occur at start up or shut down. Does your scanner app have a logging capability so you can "see" the DTC being thrown ?

I see where you are coming from on the injector. That could be dirt, or simply a "sticky" injector, in which case perhaps clearing the code and 1/2 tank of fuel plus Forte might just do the trick

You can get this, along with the general system cleaner for £25 on ebay

I say your 2020 UKS thread and the video also linked there, then looked at WIS.

Do you have the kit to do the pressure checking with Tech II ?

I note in the instructions there is a mention of "unsecuring" and "safety on" with the adapter. Perhaps it isn't a simple Schrader valve & there is someting on the adapter that allows the valve to operate to be able to read pressure.... to stop people like me & you simply depressing it to get sprayed in fuel 

Rather than the multiple cleans, why not simply soak the sensor in a bath of fluid. I would be tempted to carefully clean it as well. Nothing stronger than a finger tip, so long as the fluid doesn't irritate you.

As to system cleaners, the best is Forte, last time I looked it was about £25 for a bottle, so probably £35 now, it's what the up market garages use, because it works

Final point. In the testing there are references to having a minimum fuel level of 12% and the DTC being set when you run out of fuel. I seem to remember you have a fuel gauge problem as well, perhaps one fault is falsely triggering another ?

Classic Saab 9-5 (MY 1998-2010) / Re: Replacement catalytic converter and exhaust sensors

« on: 10 April 2024, 08:22:10 PM »

The exhaust will have two lambda sensors

Whether you need to replace them or not (if it's not broke don't fix it), the reality is that the condition of the external part of the sensors will probably dictate whether they can actually be removed without damage

Are you suggesting that I have a poverty spec TTiD 

I actually didn't know that, I need to do a post on the difference between the 2010/2011 cars as, subject to a bit of front suspension alignment work (but not much) the Drivesense cars are very different.
