yaw rate sensor location

Hi,

1.Does anyone know where the yaw rate sensor is located on an R320 CDI? and also the part number.

2.I'm getting a tyre pressure fault showing, could this be due to changing the rims to 20"?

Thanks

Franco

Yaw rate and lateral acceleration sensor is located under the front passenger carpet and subsequent floor board. Since you changed out wheels, I would start there. I would reccomend having MB hook your vehicle up to STAR system and see if there are any faults. The Yaw Rate piece is located bottom left of the floorboard oriented when you are sitting in the front passenger seat.

As my car is a UK model (Right hand drive) I presume that means mine will be under the driver's seat?

That would be my assumption, the sensor would still be under the passenger side. But, I am not positive about that though. My Star DVD does not mention the right hand drive, thus I can't confirm for you.

If you don't have pressure monitors in your 20s, your tire pressure display will fault.

This does not address yaw but I had a problem with TPMS (tire pressure monitor system) illuminating red warning lamp. Repeated adjustment of tire pressures and resetting alarm would not resolve problem. Also radio would spontaneously cancel mute.

2008 R320 CDI, original 18 inch wheels and Continental tires with 2604 miles

Mercedes of Colorado Springs January 29 trouble ticket showed cause:
"2604 glow plug control module perform short test found fault codes in the TPC module and COMMAND for overvoltage the [sic] has turned on the warning light and caused mute on radio complaint."

This diagnosis and repair made trouble go away and I haven't had difficulty since. Fortunately the repair was under warranty. Service writer told me cost would be $800 - 900.
