distronic Plus

I have Distronic Plus. However it is functioning intermittently, sometimes even disengaging whilst it has reduced the speed of the vehicle to less than 20mph. Could it perhaps need a software upgrade? It is now three and a quarter years old - out of warranty of course.

These systems don't anyway always work at low speeds. But reads to me like the radar sensors could be dirty. Pop the bonnet and have a look behind the filled-in MB badge.
