9-3 2.2 TiD 2003 stopped while driving and will not start

[Totningen]

My 9-3 2.2 TiD has almost made it to 200 000 km but stopped a couple of days ago. The engine fault light lit up, and the motor died. I tried starting, the engine sounded like it almost would start, but wouldn't.
Got it to a garage which read the following codes:

PSG16 P0017 FA - Uneven pump rotation, worn chain.
P1149 5A - Injection Timing Control Malfunction. Injection too Late.
P1627 F7 - ESP torque invalid? (translated from norwegian "ESP moment ugyldig" - not sure about this one)
P0342 2D - Pump Camshaft Position Sensor Circuit Malfunction. Internal Fault.
P0106 FA - Manifold Absolute Pressure Sensor Circuit. Plausibility Fault with Atmosphere Pressure.

The garage says there is no sign of ignition now, so the motor is nowhere near starting.
The garage believes this is cause by worn chain or defect diesel pump.

I had similar problems twice almost one year ago. Both times the car started running again without the garage being able to explain why.
First time they replaced a sensor on the camshaft or something. This didn't fix it. We towed the car to another garage. Now the car suddenly started after charging the battery (was dead after first garage's search for problems).
Second time it happened I towed it to a garage, where the car just started the first time they checked it...

I would be grateful for any ideas what to check. Both worn chain and diesel pump would cost me about 50 000 NOK, which is about what the car would be worth if OK... So I don't have any plans to change these things...

Thanks for any help!

Sorry for not responding on the issue - it's hard to see the prime source for it. Have you raised the case in the STCN forum? There are a couple of very knowledgeable members posting there.

Thanks for the response. Yes, I first tried STCN ( Saab Turbo Club of Norway • Se emne - 9-3 2.2 TiD 2003 stoppet under kjøring - feilkodehjelp ), but no response there, so I tried here as well.
The plan now is to transport it back home and who knows - it might just start again... If not, I know someone who may try to fix it, although he's not a SAAB specialist.

Does anyone have an opinion about the timing chain possibly not lasting more than 200 000 km? I bought the car when it had driven 30 000 km, and I have changed the oil every 15 000 km, so I am thinking that the chain should last much more than 200 000 km...
