I don't know definitely but to date I haven't seen a fuel pressure regulator anywhere else except in the top of the fuel return line and mounted either on the end of the fuel rail or very close to it. There is also a vacuum line connected to it.

I'm assuming your looking for the oxygen (O2) sensor on that side of the engine. Find the belts and pulley wheels on the end of the engine. Most likely the left side of the car as you look at the engine. Stand on that side of the car with the belts nearest to you. Look across the engine.
On the transverse engine fitted to Saab 9-3, Bank One is always the left side of the engine, (nearest the driver), and Bank Two is always the right side of the engine, (nearest the headlights).
Standing in front of the car look down the back of the engine, Sensor One will be positioned in the exhaust manifold or first short section of exhaust 'Before' you get to the catalytic converter. It will be a metallic tube shaped sensor with a set of wires coming out of the top end of it. I would recommend buying one of the specialist sockets or spanner's for this as they can be a pain in the backside to get access to.
each exhaust has two sensors fitted. Sensor One is always nearest the engine, before the catalytic converter, and Sensor Two is always furthest from the engine, after the catalytic converter.

Any of the issues you mentioned may be the reason for the light being on. All the light tells you is that there is a fault in the airbag system somewhere. Air bags can be extremely dangerous to work on unless you know exactly what you are doing. They can cause serious injuries or *****. You would be far better to take your car to a repairer than to try and fix this yourself. If you do not care if the airbag is not working, you can pull the fuse and the light will go out, but remember, you then wont have a working airbag.

Need a bit more info about that. You need to get hold of an OBD2 diagnostic tool (code reader) , plug it in and read off DTC's (Diagnostic Trouble Codes)
heres a link to saab.se trouble codes listing, look up the Code numbers and make a note of the codes that your car's ECM throws up.
https://saabinfo.se/en/og-9-5/error-codes/obd2-error-codes/

usual suspects are CPS (crankshaft position sensor), which are in the general area of P0335 onwards in the listing, but it could be a number of other things too. More info required please.

If all of your gauges malfunctioned this way, I'd have to guess possibly a bad ground in the dash. I would look for a loose or corroded screw passing through something that resembles a circuit board printed onto a piece of flexible plastic sheet. Good luck.

I would check the fuses first. After you confirm the fuses are good, I’d unplug the compressor and turn on the ac inside the car. With a test light or voltmeter, one of the wires should have positive voltage. Assuming the climate control unit inside the car is working correctly. If one has power when u switch it on inside and then when U turn it off the wire that had power doesn’t anymore then check to make sure the other wire is grounded. If it is the compressor is bad. Now if you don’t have enough Freon in the car it won’t kick on. The low pressure switch will prevent it from kicking on. Does your fans kick on when you turn on the ac inside? You can take and apply power to the compressor with a jumper wire from the positive terminal
On the battery and hook it to the positive wire on the compressor. If the compressor kicks on it’s good and it’s not the compressor.

The ECU must be "signed in" with TWICE unit - Tech2 only.

Saab Cars &... | Answered on Oct 27, 2018


If this is an original radio, you don´t need any code.
"Radio code" on your SID means, that the radio is probably
"divorced", so you have to change settings with Tech2.
