Hello
I got my 4ws light on now after a few reset it keeps coming back
I'm getting code 21
21 Main Steering Angle Sensor Rear 6,13 CU, RSSAS, RMSAS, HC
Where is this sensor ?

Anyone have any experience with this particular code
I havnt knocked the back to my knowledge

Then for so long it didn't come on until it was hot a few months ago reset it a coupls of times and now it came on again few days ago when it was hot and this time has stayed on

It might just become dirty being under the car, I would give it a good clean, reset the code the see if arrears again

1 of my mot advisory was my steering rack
I feel a bit of clickin at a standstill
That code 21, can that code be because of the front steering rack?
Rssas and rmsas refer to read steering and rear sub angle sensor

First step would be to check the bible man. Should be a link to the service manual in the wiki here:
http://www.ludegeneration.co.uk/wiki/in ... Literature
Grab that, it should have a breakdown of the 4WS system plus any diagnostic procedures.

Yes I have been looking through the all in 1 PDF I have for the 5th gen
This 1 is the same right?
I can't find any 4ws test procedures though
You know the flow chart 1
Does the 4th gen bible have 1

The only 4WS info is in the 4G service manual as USDM 5th gens didnt get 4WS.
