I had a rising oil problem on my bmw 520d diagnosed as a blocked DPF so i had it reconditioned by The DPF Clinic, I can’t be without my car for long so it was great that they had exchange units available. Before i had it done i felt my car was running fine, i couldn’t believe the difference driving it now the car is much more responsive. I would definitely recommend The DPF Clinic, it was well worth the money for the DPF recon and the expert knowledge that Ben was very willing to pass on to me. Thanks again Ben. Yours sincerely – John Murphy.
