With the introduction of the new fuel injectors for gasoline engines, a new retaining spring parts kit (seals) was also introduced. The old parts kit may not be used together with a fuel injector with new part number. The following assignment must be observed:
Injector A 177 070 29 00 requires parts kit A 177 072 00 00
Injector A 256 070 01 87 requires parts kit A 177 072 00 00
Injector A 256 070 03 00 requires parts kit A 177 072 00 00
Injector A 256 070 09 00 requires parts kit A 177 072 00 00
Injector A 278 070 04 87 requires parts kit A 276 072 01 43 or A 177 072 00 00
Injector A 278 070 06 87 requires parts kit A 276 072 01 43 or A 177 072 00 00
Injector A 278 070 11 87 requires parts kit A 276 072 01 43 or A 177 072 00 00
Injector A 278 070 12 87 requires parts kit A 276 072 01 43 or A 177 072 00 00
Before ordering the retaining spring parts kit, the part number for each installed injector must be checked.
