Toujours pas de réponse dommage...

@Mustapha You are correct. The car has some premium options like leather seats. I must have overlooked that. But it still is a manual. If the clutch, flywheel haven't been replaced yet, you will face a four digit repair bill very soon based on the kilometers on the clock.

As for just changing the switch. That won't work on your current car. There is no switch for front fog lights and automatic halogen headlights. DRLs and the function for automatically turning on halogen headlights was introduced in cars from structure week 2010/44 onwards. Your car is a 2008 and doesn't support that "out of the box". You would need to build your own custom light switch by combining part numbers 31318937 and 30739300 for example. And you also would need to test which CEM configuration would work on your car for this function. And you might also need to add wires from the switch to the CEM as well as relais in the CEM. There is no guarantee that this is possible at all. VIDA and EWD contain allmost all information needed for this kind of retrofit, but it's up to you if you want to spend time and money for trying to get this to work. Comparing wiring diagrams and pin outs of the LSM and CEM from a 2008 and 2012 car would be a good starting point.

Ich wohne im Wedding, bin aber mobil, da das Auto ja komplett fahrtüchtig ist. Die D5T5-Partnersuche ergab für mich leider keinerlei Erfolg, entweder waren die Nummern falsch, oder es ist niemand ans Telefon gegangen. Deswegen mein verzweifelter Formusbeitrag.

Grüße ausm Wedding!

@Caerbannog13 Hi there. Just as a tip. There is a mobile phone app called V-Tool https://v-tool.app/ which could be considered a VIDA light version. It reads and deletes codes from all ecus and allows to activated service functions like service reset, BMS reset, EPB service and so on. You just need a compatible Bluetooth OBD-adapter. As you have VIDA, you can look up the detailed descriptions of all error codes, which are shown in the VIDA format btw, and also the associated fault traces whenever you have a problem.

I'm somewhat clueless to be true. Could you post all codes that are present in your car, or a screenshot of them? Active and temporary.
The main problem is, that you already started to fire the parts canon and swapped in used parts, that could have brought additional problems with them or they are simply the wrong part, as Volvo changed some things around the transmission over time. There are different part numbers for the transmission, valvebody and so on, depending on the chassis number, if look them up in VIDA. There are also at least 5 different software numbers for TCM that I found so far. Trying to help you is like looking through a crystal ball. More or less just wild guessing. Maybe you need to visit a local Volvo specialist.

If you have a supported adapter, you could just connect your car to vdash, and simply click through the advanced configuration options, to see what is possible or not with your car. This way you can find out if Vdash is useful for you or not, before you spend money for nothing.

thank you

@Michel71 https://d5t5.com/q-and-a/detail/101 if you are lucky, this might work for you.

IMMO data stored in the BCM is lost/doesn't match your car. If you have VIDA2014D, you can try this. https://svdns.info/2025/01/08/pairing-a-used-abs-module-p1-p2-p3/
If this doesn't work it's a trip to the dealer for a BCM software reload with official VIDA.

The combination of all 3 codes indicate a problem with the map sensor.

Yeah easy to change with Vdash but its not free 115euro you pay ad you get pincode to change yourself.... or Drive to Elst near Nijmegen (Obbe Tuning) and have it done for you... if you dont want to spend money on buying vdash system and dice-vida diagnostics. expect cost around 150 euro

Also hardware retrofit.

Same problem here. I paid for FLAT CONFIG subscription and bought credits. But I only need credits for the injectors. After two weeks it still says 'Sponsored' and I can't programm the injectors. No response on my support ticket from november 29th

@wenger did you use new or rebuild / remanufactored injectors and the correct parts? Here https://d5t5.com/article/volvo_diesel_injectors you can find some info regarding injector coding.

@randysw nope. In your case, a software reload with VIDA is needed. But i'm not sure, if this is possible with used modules.

3 wires need to be changed
