2017 a3 , limp mode still on flashing heater plug light

[David alexander]

Hi I have a 2017 a3 1.6 tdi , since fuel line connector snapped , cars not been running till part came fuel was everywere on engine ,  cars dpf went on as expected with being sat there , after the heater plug is flashing still no turbo had it checked only thing came back was the dpf done 4000 revs for 45 mins so a regeneration should been complete still no joy , only had car 2 months been non stop engine lights every couple of weeks , can anyone help or suggest something I'd rather not pay audi but a part if the problem is won't allow the mechanic into the audi menu to correct the full regeneration to correct limp mode think its so you go to an actual dealership
