SHIRE / Switches
Audi A6L driver and passenger window switches are separate records
SAP-A003 and SAP-A004 sit in the same A6L catalog group but show different OE numbers and door notes. Do not merge them by vehicle name.
The catalog lists SAP-A003 as front-left, with 4FD 959 851 and 4FD 959 851 A. SAP-A004 has 4FD 959 855 and a front-right/rear door note. A broad search for “Audi A6L window switch” can return both, although a master switch and a passenger switch serve different positions.
Make door position a required field
Write the requested position in plain language and include a photograph of the original front and rear. Keep the catalog’s combined FR/RR/RL note as a reference to be checked, not an assurance that every door uses one identical assembly.
Treat the OE as text, not a fuzzy number
Spaces and the letter suffix matter when comparing printed references. Put the original marking, candidate OE and candidate SAP SKU in separate columns. A seller should confirm which listed OE they are quoting and whether the connector and button layout match.
Quote the order as distinct lines
When sourcing both sides, ask for separate quantities and line prices. The approved samples and receiving labels should retain A003 and A004 rather than the generic description “A6L switch”.
Purchasing guidance, not installation or diagnostic instructions. Confirm compatibility and specifications with the supplier and a qualified technician.
