Rolls-Royce / Bentley 
VIN: 20,000 series
Controls seats only, not mirrors
Part No: CD-6509 R
Years: 1987.5 - 1989

*Each front seat is controlled by its own separate ECU. The same unit is used on both the driver's seat and passenger seat. These units are the same for both RHD right hand drive and LHD left hand drive.

You must FIRST ship your core with purchase receipt to Proper Parts:

When we receive your core, we will install our brand-new circuit board into your ECU housing, repair your wiring harness as needed, and return a fully tested unit to you with a 5 Year Warranty. 

Proper Parts has designed a new circuit board for this control module. 

Our new control board performs all the functions of the original except memory, which eliminates the battery. The original ECU included a memory function that required a battery. These batteries leaked over time which damaged the circuit board.

Because the original ECU can fail and force your seat into the steering wheel while you are driving, we do not rebuild the original board. We replace it with a brand new control board which does not use a battery. If your mirror moves with the seat switch, or your seat moves with the mirror switch, this is a dangerous condition and the ECU should be replaced. 

Proper Parts has sold close to a thousand ECUs since 2011, and we can probably recommend a mechanic near you who has experience with our product. Just contact us.

What is the core?

The complete core that you will need to ship to Proper Parts consists of: 

  • ECU housing

 What is an acceptable core?
