Customer had been referred to us by another garage. Our initial assessment showed up a few fault codes 2 in the ECU module and 1 in the SCR module. The Adblue tank was low so we filled the tank . Which took care of the level fault in the SCR module.
Completing the assessment showed the DPF was blocked we carried out The DPF Doctor 3 stage clean followed by an engine service .
An extended road test was then carried out but we were unhappy with the way the vehicle drove a lack of power. At this point we kept a hold of the vehicle for further checks no fault codes were present at this point .
The following day another road test was carried out and tracking data eventually a fault code was thrown up for network communication . U02A3.
This was caused by a faulty sensor pulling the communication network down. The sensor was replaced and the ECU software was updated.
Once we were happy with the vehicle it was returned to the customer.
