Citroen C4 DPF clean

Out in Barwell in Leicestershire, This Citroen C4 had a blockage in the pipe going down to the front of the DPF 90-degree bend (Not a good design) so the DPF pressure was slow to come down and go up. This caused the DPF sensor to give false readings so it would not regenerate properly. This is a common issue on these C4s Luckily it was not too far blocked we managed to force the liquid into the pipe clear the blockage and clean the DPF at the same time. The customer had been going from pillow to post with this issue with some outrageous quotes to put it right
