I would start checking the wiring, starting from the engine bay. Take your time with a good torch and start from the exposed portions of the wiring under the bonnet. Then remove the acoustic cover and then the ECU box cover. Look for obvious damage and chafing.
Also, iirc, there is a suspension or transmission ECU on the firewall, that's behind the battery on a LHD model. May be worth checking it's wiring as well...

yea will do .....got to something simple well i hope ,i mean it can only be a couple of things L405 2014 Loire blue Autobiography

Ok I have put back in the original abs ecu (as error codes where the same) but I found this (see photo missed it before) I have cleaned it up , could only clear the error codes using gap tool -calibration-steering angle sensor and all cleared did a quick test drive seemed ok but had this before………I wondering if the sas could be intermittently faulty also did have anew error code (see photo).any thoughts guys ?

but wheni run live values for the abs sensors they are all good same as the sas ,if there are some other live values i should be checking could someone let me know (still new to the gap tool)

Can't see the photos (404 error) but the SAS can indeed be faulty intermittently.

Granted it's a different part design, my SAS would be OK one day and another wouldn't. Seemed to do well at low ambient temperatures and almost always failed after the car was left sitting outside on a hot day...

Looks like mine is ok in the sun …..I’m going to change it anyway if it’s started to play up it’s not going to get any better L405 2014 Loire blue Autobiography
