Dpf problem e70

We were presented with this Bmw X5 E70 3.0 litre 2007. Customer complaining of lack of power and Dpf light on.

After our diagnosis we found various faults inc 480A 481A 4D00, one of the main faults were a tuning box was fitted to the vehicle causing the vehicle to over fuel!!  This will then produce more soot causing the dpf to block up. We removed the tuning box and carried out the repairs then reset all required settings on the vehicle then carried out our 3 stage cost effective Dpf cleaning here in Blaenau ffestiniog Gwynedd  North wales, saving the customer money and having the vehicle back on the road quickly.
