Do not replace any assembly part without performing a guided diagnosis first!
Ideally, for fast and correct diagnosis, both keys should be available.
Therefore, when the customer arranges an appointment, ask him/her to bring both keys to the arranged repair appointment. If this is not possible, it is essential to observe the correct diagnostic path during diagnosis using Xentry Diagnostics!
Always carry out diagnosis in full up to and including the note referring to the assembly part to be replaced.
Implemented diagnosis steps will be stored in the EZS and ELV control units. When the assembly parts are inspected at the warranty claims department, the diagnosis steps taken by the workshop can be identified.
At the end of the respective test steps a note with the request to prepare a printout appears on the display.
It is essential to enclose this printout as well as the printout of the quick test with the assembly parts returned via the warranty channels.
During the warranty inspection we will be checking whether the parts have been justifiably removed, based on the diagnosis results. If this is not the case or if the diagnosis printouts are not included with the parts, we reserve the right to refuse any warranty claims.
The same applies when the requested assembly parts are not demonstrably forwarded to the warranty claims department.
All the assembly parts requested by the warranty claims department and mentioned in this service information must be returned.
The assembly parts are returned via the respective return shipment process for the market.
These assembly parts are explicitly excluded from the "Handling keys and other theft-relevant parts" circular.
