V50 P1 - Language change + key reprogramming without original key codes

aiveo

Hello,

I recently purchased a 2006 Volvo V50 2.0D (P1 platform) imported from Germany, and I have two issues I'd like to resolve using VDASH.

Language change: The dashboard and infotainment are in German. I understand this requires a DIM/ICM software reload, and I know that VDASH + Super J2534 can handle this. I plan to order the Super J2534 cable from your shop.
Key issue: The car came with two keys. One works perfectly (central locking + engine start). The second key only works for central locking but does NOT start the engine — the dashboard shows "Schlüsselfehler - Erneut versuchen" (Key error - Try again) when I insert it.

I do NOT have the original packaging or the key codes for the second key. The Volvo dealer told me they cannot program the key without these codes.

My question: Is VDASH able to reprogram the transponder of my second key without the original key codes? I understand VDASH can calculate the IMMO code from the CEM via OBD on P1 platform — would this be enough to fix the key?

@aiveo the language change is no problem with vdash. This doesn't require any pin code, just a good quality adapter like the Super J2534 and a good power supply/charger.

As for your key problem. You will need the IMMO pin to program a key . And you need to read out the car for how many keys are paired with the immobilizer and if there are any IMMO DTCs. Pairing your not working key again should be possible without the code card. The security codes are only for the fob part of the key. The big problem here is, that the ID48 chip (Transponder) https://d5t5.com/eshop/detail/241/id48-immobilizer-chip-for-p2-and-p1 in that key could be damaged, so the fob still works for locking/unlocking, but the immobilizer doesn't recognize the key to start the car anymore. Another problem with your car is general immobilizer problems. The 2.0 D is infamous for loss/corruption of immobilizer data. Vdash is able to fix this.

General tip for all V50s, especially with your engine, always keep an close eye on the battery. Low voltage conditions will bring you really big trouble on these cars.

Thank you for the detailed answer! I'll order the Super J2534 cable to start with the language change. For the key issue, I'll diagnose it once I have the cable and see what VDASH shows regarding the IMMO data. I'll also keep a close eye on the battery as advised. Thanks again!

I'll order ID48 chip at the same time just in case

Hi everyone,

Quick update: I received the Super J2534 cable and successfully changed the language to French. Thanks for the help!

Now I have two remaining questions:

Key programming: I'm not sure what the correct procedure is. Should I first decode the CEM (screenshot 1)? Or should I go directly to the key adding utility (screenshot 2)? Also, since the remote (central locking) already works on this key, will using the key adding utility remove that pairing or will it be kept?
Service message: I have a 'Engine service required' warning message on the dashboard at startup. However, in VDASH the last service was recorded only 500km ago (screenshot 3). Is this something I can reset via VDASH?

Thanks in advance!
