Oh, well, never mind let's see what treats are in store

First to come off was the tank tape for the centre section. Oh, where's the circuit board, where's the boards that have the inner LED's mounted 

This is looking bad, so lets'have a look at the outer LED mounts. Even worse, no casing exists, the hole is filled with sealant, the flexi strips are gone, wires are snipped and the weatherproofing is of such high standard that there's a good degree of moisture & rust in there. 

The total on the invoice was £300, including £26 for two LED festoon bulb replacements (which I have already replaced with filament, as Saab specified)

I'll have to see if I can figure out a way to wire & fix some of the alternate LED's I have in place, with an appropriate resistor(s) to limit current and further LED failures, but that is not for today

To top it off, I replaced the tensioner pulley today and the drivebelt is still squeaking. Further investigation required. There's only alternator, steering pump & aircon compressor remaining to investigate, but nothing was obvious from first inspection

Today is going to be a less than successful day.

I decided to take a look at the light bar, with confidence that whatever the problem was I would be able to fix it. I mean, there's aven an invoice that says the light bar was removed, wiring was checked for burns / damage, then wiring repair made to harness an confirm wiring now OK. Followed by removal of the light bar again and carried out a further repair to stop it from working (apparently a BCM error was being triggered)

Removing the light bar showed this.

Someone has definitely been in here before, and I'm not sure about the quality of workmanship, as a part has been cut out that shouldn't have been

Sauntering around the Saab EPC, I spotted that in the page for the turbocharger there was a support bracket that acts as a brace between the turbo and the engine.

That was missing on mine, so I got one from ebay off something called a Vauxhall Astra VXR 

As the studs were also missing, a quick visit to Toolstation for some 10mm threaded bar provided the necessary fixing points.

The bracket is quite chunky, as though it has to take quite a lot of force, so I'm glad that I have fitted one, though because space is so tight, this involved removing the cat to allow sufficient access to put the brace between cat & block. Fortunately, all the nuts were clean and rust free, having just been fitted a few weeks ago

I'm intrigued to know how anyone could know it had been as low as 5.5v, unless that is what it read when the AA man arrived

A fully charged battery should be 12.7 volts (disconnected, as especially on modern cars, without a proper ignition switch, circuits can become live from just opening the doors)

A "flat" battery is ~ 12.1 volts, but as I have found, the NG starts fine when the battery shows an indicated 12.15v. It's those live circuits

I have replaced the battery on the TTiD. Voltage seemed fine, but the cold cranking amp test showed it was on the weak side. The car now starts better & I have another emergency battery that is too good to weigh in, but not really reliable enough for going away on long journeys with

Excellent news & well done - I assume the MOT place collected & returned it for you, avoiding insurance complications

On using Vauxhall dealers, one was helpful, but needed a reg number for a part when I didn't have the number to hand, still very covid with no parts counter & card only.

So I went to another one who treated me like a trade account, even gave me a trade supplier phone number. Guess which one I won't be going back to in a rush.

Airbox intake id £60 from Vauxhall, who have none, no backorder delivery time either, £82 from Saabits. I'll be checking Insignia scrappers again...

Main Stealers can be quite uncooperative can't they... anyway, how did the MOT go ?

In that case I think you should consider staying in the passenger seat

Lots of well engineered solutions here

At a price

My brake light fix cost me £6, the first light bar about a tenner, with plenty of spares left over

Those connectors are actually qute good at keepng water out, if I recall correctly, they look very similar to the OG9-5 connectors for the Lambda sensors & CPS

Can Joe just pull the connector off while it's being examined for the MOT. It'll save getting the lift equipment out for you, at least for that job.

The exhaust was welded up last night and fitted today, seems to be OK and not blowing, so those exhaust gases can get away a bit quicker now.

Next little job was to do the centre brake light. Quite a lot of the lights were out or dim, so this  is what I did:

Remove earth from battery
Lower rear seats
Remove 3 plastic retainers for the shelf trim
Pull forward the outer seat bolster froom the top
Remove the "Airbag" cover from the C panel covers, and remove the 7mm bolts - hence battery off
Pull off the door seal so that the trim section can be withrawn by pulling on the trim to withdraw the 3 locating clips of the C pillar
Unplug the electrical connector from the right hand side
Wiggle the trim cover off

Next is getting to the circuit board:

The light housing is secured with spring clips. The plastic holding the housing WILL break, so it will have to be screwed back together with a couple of self tappers
Pull the sticky tape off to release the cable & withdraw

On the workbency the plstic cover is removed by pressing on the 3 retining tabs from the back
The circuit board can then be withdrawn & examined.

There are 24 LED's, which seem to be grouped into 3's, with the polarity of the LED's following this pattern (1 - 12, counting from the cable end)

+ - + + - + + - + + - +

13-24 follow the same pattern

Handily the diode test on my meter not only gave the forward voltage, but also illuminated the LED's

In total I think I replaced 4, and reflowed one group of 3 which sometimes flickered. All you need is a basic soldering iron

Best include a link to the LED's https://www.ebay.co.uk/itm/185441246744

No photo's of the finished result (you know what a good one looks like anyway), but here's a photo of the components prior to reassembly

Having fitted the new toys, I moved onto repairing the lightbar. This was achieved by replacing a couple of failed LED's

I added to a useful thread over on UKS https://www.uksaabs.co.uk/UKS/viewtopic.php?t=200095

Next job, having fitted the upgraded turbo was to remove the restiction in the front pipe that the MOT man had pointed out to me.

Now, these exhausts are no longer available, especially for the XWD, not even for the Insignia equivalent, so time for a bit of metal fabrication as the flexi that was fitted was clearly a repair, judging by the amount of pigeon splatter. The centre silencer is a very unusual triangular design to accomodate the propshaft.

So, I have a 2 1/2" ID flexi to replace the 2" one that had been fitted. It's all cut and after a bit of work cleaning up the weld areas on the OE pipe where I have cut the old one out, it is now ready for some tack welds to ensure it will fit correctly before going for the seam weld. Well, I will try to have less splatter than the last person that worked on the exhaust

Long thread here:

https://www.saabcentral.com/threads/p0089-code-2-8l-v6-any-experience.188411/page-7?nested_view=1&sortby=oldest

Some insight, some rubbish, especially when people confuse the MAP sensor with the fuel pressure sensor

I already looked for Insignia errors. They exist, but little useful information.

The above thread indicates that the parts from a 2WD fuel pump can be fitted to a AWD pump, if the AWD pump is not available, oh and a lot seem to fail at the 65-70k mark.

Other than that I think your list of possibilities is fair. I used to think a couple of hunderd quid for a fuel pump swap was expensive...

Oh and are you using standard E10 or premium E5 like V-Power

Good news on the MOT, another year of life extension.

I suggest you get some Bilt Hamber Hydrate 80 & apply that to the rusty areas. Following Will's recommendation there was a phase where this was pretty much a pre-MOT exercise, but now the chassis side hardly ever needs work on my cars.

Perhaps of some use, especially when a workshop posts a query:

https://www.saablink.net/threads/fuel-pump-and-p0089-2008-v-6.120981/

https://www.saablink.net/threads/9-3ss-v6-fuel-press-reg-performance-p0089.47822/

I haven't found any details of the relevance of the modes, but the injectors are rated at 360ml / minute so 2.16 litres / minute

They obviously operate on duty cycle so I suspect the operating modes up the basic flow rate, stepwise, which is then fine tuned by Motronic to meet engine requirement via duty cycle,

That's quite useful:

Are the dips in fuel pressure single data points, or are there a number of data points at those low pressures

This could be "correct" if the fuel pump had been instructed to move into mode 1 or mode 2, but we don't know enough about the purpose of the different operating modes.

A comparison between PWM and fuel pressure should be quite instructive. I would even go so far as to calculate a ratio for each data point and graph that. I suspect, like you, that fuel pressure is dropping when PWM is not giving the instruction
