The exhaust gas back pressure levels were 500 mbar at 2500 rpm on this poorly BMW this morning sending it into limp home mode with fault codes 480A, 481A and 4D00 present. We also accurately diagnosed the reason for the failed regenerations.
After our 3 Stage DPF clean the back pressure was reduced to a mere 35 mbar.
For accurate DPF diagnostics and specialist DPF cleaning you need The DPF Doctor!
