Apparently the Jetex sounds very nice- not too roarty. I've also heard that if you take your car to them there's a good deal to be had with fitting.

It hasn't recurred. Will have a look at the rings when the weather is a bit better...

As above- driving back over Xmas on a straight motorway at a steady 50ish, a few times I felt a sharp tug from the front nearside. On around the third occasion it briefly flashed the ESP logo on the dash. Couldn't subsequently provoke it on any twisties. As it's a single wheel, I'm thinking maybe an issue withe steering angle or maybe yaw sensor rather than an ABS ring- thoughts?

The connector that goes from the airbag leads to the CIM connection can be temperamental. I found that on mine, and eventually cured it with a new (used one).

Have you checked the resistances with Tech 2?

Try taking the airbag off and pushing the connector home whilst looking at the value on Tech 2

Yes, that's one of the most common causes of a damp footwell. Easily fixed with some new EPDM foam tape.

So, resolution. I bought a new stat, and removing the old one I found that I'd managed to not align it properly when fitting, so the seal ring had become torn and presumably water was leaking past there. Odd why it's deteriorated though.

Checking the temperature of the heater matrix hoses with an IR thermometer, it would appear that the temp sensor is reading a degree or two low. I can probably live with that.

Wow. That level of corrosion on a relatively young car is quite worrying.

I wonder would an Insignia subframe have at least the same mounting points so you could chop out the bad bit and substitute it.

« on: 02 February 2024, 12:59:07 PM »

Bit of an assumption here. If what the ECU is doing is taking the lowest value and using hat for the fuel gauge, if you were to substitute a resistor of the same value as full on the faulty one, then the ECU would still defer to the lower reading from the other sensor. Maybe not quite as accurate, but it would be better than what you have at the moment.

All Saab's fuel sensors are resistive up to the point they get to the ECU. Some pumps use PWM to control the flow rate though.

As you say, there's two sensors for the AWD version but it's not clear how the Motronic ECU handles the information. However, given that the sensors are high impedance when empty, I would speculate that one of them has an intermittent open circuit.

The actual bottle would be the least likely culprit IME. Could be the pump casing, seal around it where it pushes into the bottle or connecting unions.

I think the loom for the towbar plugs into the rear electronic control module along with the towbar module- that's how it is on the NG9-3 at any rate and it looks similar in the parts catalogue

Yes, towbar electrics do need a control module, the good news is it's common across other GM models so shouldn't be hard to find GM 13505411.

If you're lucky maybe the same will apply to the plug in cable harness

The list price is daft- circa £50 but you can get them for around £25 delivered. Still over twice the price of a genuine one for a 900, 9000, 9-5 etc.

No, I haven't tried the pan test yet. But it would be odd for 3 of them to be faulty. The fact that the cabin heater is slow to warm up suggests to me that it's not a sensor/reading issue. I suppose what I could do is disconnect it and measure the resistance with the engine warm and compare it to the spec.
