Hello All,

Happy 10th birthday to SAABWORLD long may you last!

Hope my story below is not too long and boring, the first part is what actually happened and the second is what codes I downloaded with an OBDII.

I have a 95 Aero Auto (Sentronic) RHD MY05, a few days ago after parking the car and shifted from D to Park the car jerked quite viciously and made a thumping noise as the shifter moved from D through N, R to P. I switched off the engine.

Restarted the car and got the following warning lights; Central warning light, Brake warning light, Handbrake warning light (the handbrake was on), ABS warning light and Airbag warning light, Engine malfunction indicator light. Fuel gauge showed empty, the Selector lever indicator is showing ‘P’ and it is in Park.

Switched off and restarted; fuel gauge now registering, the warning lights on as above plus Automatic-transmission indicator on, car in 'Park' no Selector lever light on.'

Engaged ‘R’ accompanied with a jerk and thumping noise, it would however reverse, note no Selector lever light on. Engaged ‘D’ with more jerking and thumping noises, no Selector lever light and the car would barely move forward ‘limp mode’?

When I bought the car four years ago it came with a trunk full of spare parts, one of them was this ‘gear selector position sensor’.

Should I replace the one in the car with it?

Second part of the story. I downloaded the following codes with an OBDII reader. The reader is an OBDLink LX which I sourced from Scantool.net and used an Android app on my cell phone from Torque Pro.

It gave me two current faults; P1623 and P1625 both relating to the Powertrain, no SAAB’s mentioned – BMW, Chrysler, Mazda, Mitsubishi, Dodge etc.
Went to this site https://saabinfo.se/en/og-9-5/error-...2-error-codes/ and looked up the codes there and got the following:

P1623 Immobilizer Code Word/ID Number

P1625 B+ Supply To VCRM Fan Circuit Malfunction

I have no idea what these codes are telling me. Any help would be most welcome.

Kind regards,
