Part #'s Bosch & Siemens Fuel Injectors for 96-A4-Q-2.8-12v???

I checked my fuel injectors resistance today--average resistance 14.7 ohms.

According to the Bentley Manual, Bosch should have a specified resistance value between 15-17 ohms, and Siemens should have a specified resistance value between 13.5-14.5 ohms.

Thus, I likely have the Siemens part.

Factory manual recommends replacing "any fuel injector for which resistance measurement does not fall within specified value."

Does anyone know the part #'s???

Those are the Audi Part Numbers...I've been looking for the Bosch part numbers for a month now.

I'm still trying to find the flow rate of our injectors. Somebody mentioned that they "thought" they were 200CC, but in my mind, that's still unofficial.

If we knew the real Bosch part number, we should easily be able to find the flow rate, but so far, I haven't been able to come up with it.

Thanks,
Scott
