egr vauxhall astra 2.0 dti j?

how do you force the diesel turbo astra to regenerate EGR?

How often does it need regen if your average trip is only 6 miles?
Jim B, December 2016
A forced regeneration can only be done if you have the correct computer like Tech 2,your ECU in the motor will decide when it needs done through sensors either side of your DPF measuring the difference in pressures, it needs careful consideration nowadays whether to buy a motor with a DPF if you are town driving all the time.
