Hi,

 

Quick one for you gurus out there - I keep getting the error code above...

 

Have read a few bits and pieces on it, and to my understanding it's related to the 'clock spring' sensor that fits behind the steering wheel?

 

The part isn't 'that' expensive to swap out, just want to be sure I'm swapping the right thing!

 

Any thoughts / comments would be very much appreciated.

Welcome to RennTech :welcomeani:

 

Sorry, but the clock spring is not the issue, it is the steering angle sensor:

 

P4420


Possible fault causes
- Short circuit to B+ in wiring harness
- Short circuit to ground in wiring harness
- Short circuit between the signal and ground lines of the rate of turn sensor
- Open circuit in electric circuit
PSM(TC/ABS) control unit faulty
NOTE:
Calibration of the steering angle sensor must be performed on a
measuring platform. The steering angle sensor must be calibrated
after work has been carried out on the running gear in the area of
the front axle. The security code is required for calibration of the
steering angle sensor. The security code is read with the PST2
under menu item "Actual values". Calibration is described
in⇒ Rep. Gr. 4560; Calibrating steering angle sensor.

 Hi bud,

 

Thanks for the welcome, will give a bit more background about myself soon!

 

I wondered if this part - https://www.design911shop.com/pages/productList.aspx?search=95565221112 is what I need? For sure it is a 'clock spring' but it details that the angle sensor is contained within it?

 

Appreciate your help and info so far...

 

Regards,

 

Ian B

That is the steering angle sensor, which contains the clock spring on your car.

 

You need to also be aware the code you have indicates you may have a harness short, which replacing the steering angle sensor may not correct.  More diagnostics are required, and if the steering angle sensor is the issue, the new one will need to be calibrated after installation.
