Japan-spec 2025 Taycan 4S Cross Turismo to Europe – PCM conversion + My Porsche / Porsche Connect issue

Hi everyone,

I’m considering buying a 2025 Porsche Taycan 4S Cross Turismo (facelift/J1.2) that was originally sold in Japan and has now been imported to Cyprus (EU).

I have already spoken with a specialist who says he can perform a Japan-to-Europe software/PCM conversion, which should give me:

  • European navigation/maps
  • European FM radio frequencies
  • Wireless Apple CarPlay
  • European region/settings
  • Other EU-specific PCM features

However, he told me that even after the conversion, My Porsche / Porsche Connect will most likely not work, because the vehicle/VIN is originally registered for the Japanese market.

Having the My Porsche app and remote services is very important to me, especially for a Taycan (remote climate control, charging status/control, vehicle status, location, etc.).

Has anyone here successfully converted a Japan-spec Taycan to European specification AND managed to get My Porsche / Porsche Connect fully working in Europe?

I’m particularly interested in knowing:

  • Can Porsche officially change the vehicle/VIN market assignment from Japan to an EU country?
  • If Porsche refuses to change the market assignment, is there another legitimate solution?
  • Can the original Japanese Porsche Connect account/eSIM work through roaming in Europe?
  • Is replacing the telematics/communication module with an EU-spec module a possible solution?
  • Would an EU telematics module still require Porsche backend activation for the Japanese VIN?
  • Has anyone successfully done a full PCM + telematics + Porsche Connect conversion?
  • Are there any specialists in Europe/UK who have successfully done this on a Taycan?

I’m not interested in VIN cloning or anything that could cause problems with Porsche diagnostics, servicing or future software updates. I’m looking for a proper long-term solution.

The car is a 2025 Taycan 4S Cross Turismo, Japanese specification, facelift/J1.2.

I’d really appreciate hearing from anyone who has actually dealt with a Japanese-import Taycan or a similar Porsche Connect region issue.

Thanks!
