Having replaced the ECU with a new one the car shows ABC BAS PTS not working on several occasions. This can be reset by shutting the car down for 15 seconds then the car searches for the stored fault once it finds no faults the car displays normal operation. Can anyone shed any light on this fault. My technician explains that the distronic radar is susceptible to interference and this triggers the faults listed. Does anyone else suffer from the same fault?
Thanks

A quick up date on this. The car displays ESP ABS PTS and distronic unavailable on several occasions and can be cleared by shutting down and restarting. Having now been into dealership, they say it could be a trigger from the Xenon light or the xenon driver 98% sure or ESP sensor or ABS sensor
 
Wheel speed sensor?know to be low quality part and messes up the abs, traction control and stability systems.
 
My technician explains that the distronic radar is susceptible to interference

It's true that it is susceptible to external interference from other radar systems, radio/TV transmitters, etc, but that normally causes Distronic to temporarily disengage with a warning message. On my earlier version of it the message is 'Distronic External Malfunction'. Normally it can be re-engaged almost immediately unless close to a very powerful transmitter.

I doubt if Distronic is the source of all the other problems but rather is a symptom of something else wrong.
