YES!
BUT: It does NOT MATTER: IF you are also missing N51 "SULEV" engine.

That spot on your JB Junction Box Fuse Panel is for K6304 "Secondary Air Injection Pump Relay" which is NOT used on on N52 "ULEV" engine.

There are a LOT of fuse locations & such on the JB Panel that are ONLY used in certain Model/ Engine/ Tranny, etc. configurations. ALL E9x models are NOT alike.

ALWAYS Provide Last-7 Characters of your VIN if you want CORRECT information for YOUR vehicle.

Thanks George. I wonder if this is the culprit behind my P1429 code. The last 7 of my vin are: AZ87624

2006 BMW 330i

Is there a part number for this relay?

1) The K6304 Relay is NOT installed on N52-Engined Models. That is because there is NO "Secondary Air Pump" used
on N52 Engine. There IS a "Secondary Air Pump" (M63) used on N51 (SULEV) Engine. E9x models with N51 engine have
the K6304 Relay installed where your "Yellow Circle" appears on Lower Left of JB Fuse Panel used until 3/1/2007.
First concept needed here: There are MANY Variations of E9x models, with different engines, other systems, & Options.

Attached are ISTA ScreenPrints of the "Secondary Air System" which show where components appear on N51 Models.
The LACK of a Relay for an Air Pump YOUR N52 does NOT have, has NOTHING to do with P1429 Code you
reported in another thread. That P1429 Code indicates an issue with DMTL Heater circuit.

2) Virtually EVERY part in your 9/2005 build 330i has an 11-digit BMW Part#. That K6304 Relay is NOT used on N52-Engined
vehicles. YOUR vehicle is NOT equipped with SAME parts used in a diesel-engined 330d E90 EITHER.

If any questions about the attached ISTA ScreenPrints, please ask. Best way to LEARN.
