Help please fault code 4440

[Sunnysidebb]

Hi,
Sorry I have a fast ball.
I am on my way down to Sussex for Loch Lomond. Got the usual PSM/ABS failure lamp twice so far ( 300 miles to now). Stopped of at relatives for tonight in Chester.Checked with my durametric ABS fault code 4440.
I cant find any ref in the manual.All I know is steering angle sensor failure. Cleared fault OK. BUT...Cant find anything about 4440.
Does any one know where to find it in the workshop manual.
Thanks
Frank

Had a quick Google Frank and came up with this which I presume you know already.

Googled it come back with,,
If the fault codes 4400 "Transverse acceleration

Thanks Martian ,
No I didn't know this.That explains why I cant find it in the workshop manual. I was getting the ABS/PSM alarm earlier on this year but I cleaned the MAF, not had it since, until now. This is the first time it has done it since I bought the Durametric so I wonder if code 4440 has been the culprit before.
I am heading on down further tomorrow, problem is I would like to check the durametric before switching off the engine, but on the hard shoulder that's just not a good idea and you have to quickly switch the engine off to get the ABS/PSM to switch back on!!

Frank you should be able to just switch the ignition off and then back on whilst you are driving to clear. You don't need to stop to do that...just don't pull the key out

It sounds like your wheel alignment is screwed. 4440 is steering angle sensor.

Don't think it is your MAF. Have you not got the spare one with you?

Calibrate the steering angle sensor with the wheels in straight-ahead position!
Note
Check the steering angle sensor actual value with wheels in straight-ahead position before calibrating the steering angle sensor! Only recalibrate the steering angle sensor on the measuring platform if the steering angle actual value lies outside the tolerance or is doubtful!

1. Drive vehicle onto measuring platform. Affix measured-value pickups to all wheels.
2. Check wheel alignment values and adjust if necessary.? If the wheel alignment values on the front and rear axles are correct, calibrate the steering angle sensor with the front wheels in straight-ahead position. Calibration description in following text.
3. Connect the Porsche System Tester 2 to the diagnostic socket.
4. Select the "Calibrate steering angle sensor" menu with the Porsche System Tester 2 in the PSM system. Entry to the PSM system takes place through the ABS system (automatic status change after PSM).
5. Confirm calibration start. The procedure can also be interrupted.
6. The PST 2 now requests the 4-digit safety code shown in the display.

Note
This safety code must be extracted in the Actual Values menu, Safety Code sub-menu! The safety code changes automatically each time provided that PSM is called up again!
The calibration procedure will be interrupted if an incorrect safety code is entered! This time-consuming procedure ensures that the steering angle sensor is not calibrated unintentionally!
The steering angle sensor can be calibrated several times! The value (the zero position) is stored in the steering angle sensor itself!

7. Input the 4-digit safety code with the cursor keys (4 centre keys on right). Then continue with the (>>) key.

Note
The final possibility to interrupt the calibration is not to confirm the safety code input! To do this, press the appropriate function key for no!
Important for calibration: The wheels of the vehicle must be in straight-ahead position
.
8. Confirm safety code input with wheels in straight-ahead position. Display in the Tester display after the safety code input has been confirmed: Steering-angle sensor being calibrated.

For safety reasons, read out the current steering angle sensor actual value after calibration. To do this:

9. Leave the PSM system. Then call up PSM again and select the steering angle sensor in the Actual values menu. Required display in the Tester display: 0° ± 3° when the wheels are in straight-ahead position.
10. Repeat the calibration if the value is not correct.

Hi Ken,
Thanks.
Yes that's what I do just a quick flick of the Key.
I will have a chat with you next Friday if that's ok.
Sending you a PM in a moment.
