Hello Everyone :D .
My name is Michael , I'm form Poland, I have a problem with my 850 2,0 T5 94year:
1. When the temperature outside is behind -7 / +10 C I have a problem with starting the engine. It started, but this take me about 5-10 sec. When the engine is warm everything is OK. Specialy this problem is at the mornig, when my 850 is cold.

Is there anybody who know what is wrong ? What is faulty ? Maybe it's normal, but I don't think so. In owner manual write that the Turbo engine could started up to 10sek, but in my opinion it's very unlikely, especially that it depends on outside temperature.

2. When I ride longest distance than 50km, Lambda sensor start lighting, and in computer I see fault code: 2-3-1 and 3-2-5. What does it mean ? Computer and lambda sensor problem ? Why ?
I know that lambda sensor doesn't come influence on starting engine.
Everything except these problems is OK, no more fault codes.

Please help me if it possible ( could be in Swedish, I understand it).
Thank You and many greetings.
Michael

Fault code 2-3-1:

Fuel Trim (FT), part load too weak or rich [Bosch LH Jetronic 2.4]

Probable cause:
- Intake/exhaust leak
- Fuel Pressure
- Excessive fuel in engine oil
- Injector(-s)
- EVAP canister purge valve
- Wiring
- MAF Sensor
- ECT Sensor
- H02s

Fuel Trim (FT), part load to rich [Bosch LH-Jetronic 3.2]

Probable cause:
- Fuel Pressure high
- Excessive fuel in engine oil
- Injector(-s)
- EVAP canister purge valve
- Wiring
- MAF Sensor
- ECT Sensor
- H02s

The fault code 3-2-5, means memory failure. My opinion is that you should look through the list above for first, so you can maybe find the cause. If you can't find the cause of your problems, try to erase the fault code from the car, look below, and see if it comes back after erasing:

Ensure that ignition is switched off
Insert selector cable:
Fuel system - in socket 2
Ignition system - in socket 6
TC system - in socket 5
Access trouble codes

Important: Fault code must be displayed at least once before you can erase it!

Depress test button for approximately 5 seconds
Release test button
Wait for LED to illuminate
Depress test button for approximately 5 seconds
Release test button
Release test button for approximately 1 second
Ensure that fault code 1-1-1 is displayed, which means no problems

So, that's it. Look through my list and if you can't find the cause of your problems, try to erase the fault codes on your car, as I said. Good luck!

Thank You very much.
I found what was faulty.
In my car I have LPG (propan-butan) sequential gas instalation and the computer from LPG was badly set to bensin computer.

Now when I repair this everything is good.

Thank You
