Hey there - my first post, new owner of a 2008 X5 E70 with the 3.0 si + comfort access. When I bought it it was already throwing the TPMS codes for the RDC module (Antenna under the driver side) + all 4 wheels. Considering the age of the tires (mismatched from multi years/brands) I did the following.

Just put new tires on the car and when I did I also added new OEM TPMS sensors to the wheels that transmit on the 433Mhz frequency. I own a Launch TPMS tool and I verified and “initiated” the new TPMS sensors in all 4 tires. ** Discount tire didn’t want to do that and said the typical “It’s a BMW it will reset”

Using my launch tool for TPMS, I cleared the DTC’s and all 4 tires showed green. I then OBDII loaded the scanned TPMS ID’s into the ECU. Change took and then I went for a drive…2 min later “Bing!”…TPMS with same 5 error codes for Antenna and 4 tires

I bought off of eBay a used Antenna (Part # 6 771 043-01), as well as a set of 4 used Transponders (Part # 6 771 042-02 01). I also bought a new RDC module for under the dash (Part # 6 782 800-01)

This completes the total of 10 parts that make up the TPMS system.

I found the Antenna pretty easy under driver side above the plastic cover…
But I cannot find in the front wheel well (Left or right) the transponders or the wiring for them ?? Can anyone point me to a diagram/image that shows the locations? I have done multiple google searches for text and images and come up empty. Found a great you tube for this issue on a 2007 e70 but locations are not the same exactly, but also why I’m hunting these transponders in the front wheel wells/bumper area

Thanks for the read and assist
