This afternoon got a A7 which came for a diagnosis after some electrical repairs done somewhere else. Check ON , diesel flashing, no acceleration over 3000 rpm. After a full scan , engine had sensor 1 for EGT , particle filter overloaded and under efficiency . After a short checking in the engine bay, i discovered sensor 1 for EGT wiring chewed through by a mouse ( intial problem at the first shop where they repaired few other wires but they didn't discover this one). After fixing wire , error for EGT sensor 1 was gone, engine still in error/limp mode because of DPF overload ( 13.55 g measured and 39.90 calculated ) . Last regen was around 794 kms ago , so i sent the customer on a 50 kms regen effort by himself, but that failed . Customer asked for a static regen and i started the procedure ( i usually don't do static regens but it had a crazy UDS ecu and i didn't have the patience to mess around in Adaptation channels for regen while driving , so i entered BS and did a static one ) , which took about 25 mins . After full regen ( down to 1.74 g measured and 2.40 g clalculated) , no more erros . Customer happy , gave him a 20 % discount for diagnosis , wire repair and regen because he's a repeat business client. Car was a UK model ( right hand drive ) , i asked the customer to take a short video with the car in the "smoky phase" . Video doesn't do justice to the actual thing lol
Initial log ( edited for engine ecu only ) :

End of regen ( the engine RPM got back to normal ) and the values for measured /calculated came down nearly close to one another
