Customer statement / workshop findings: For any interior veneer replacement: raise and obtain approval of a Technical DISS query before ordering. This ensures VIN correct specification and prevents visual mismatch.

Technical background: Conversion of a vehicle for use in a market other than the one for which it was originally designed or intended is not supported. Enquiries related to conversions or retrofits of vehicles from (or to) other markets (e.g. reimport from USA or UK) are not supported by Technical Support. Vehicles are developed and constructed according to specific market requirements of the respective destination country. As the compatibility of different components (e.g. control units) cannot be defined comprehensively regarding their mutual dependence and interaction in the case of modifications, and in order to prevent danger or risks due to constructional changes, support or advice regarding these modifications cannot be provided.
