Regen...it will only allow it at certain times even a forced regen can not be done if it has been done or attempted more than 4 times.
Some later cars will not allow a stationary regen now as engines have been lost.
The manufacturers software stopping you.
So i only now carry out on the road regen.
Criteria are min 1/4 tank of fuel...no codes in engine ecu....speed above 60mph then at this speed select on scan tool road regen.
