Diesel Particulate Filter warning light flashing and fault code stored P2459 DPF number of regeneration cycles too high.
The fault was cured by using Clean & Protect, 45 minute Advanced Formula Motor Flush adding Oil System Protector to the new oil and adding DPF Cleaner and Regenerator plus Advanced Formula Diesel Treatment to the fuel tank. The car was then taken for a 10-20 minutes road test at 40-50 mph to allow regeneration of the particulate filter.

Problem with a VOLKSWAGEN TOURAN 1.6L FSI
VOLKSWAGEN TOURAN 1.6L FSI 2004 111k
Oil pressure warning light on when running on idle. The oil pressure was tested showing 0.2 bar on idle. The minimum pressure required to prevent the oil warning light coming on was 0.3 bar.
The fault was cured by carrying out a 45 minute Advanced Formula Motor Flush adding Oil Fortifier to the new oil. The oil warning light went off and the pressure was re-checked, which increased to 0.4 bar on idle. The oil pressure also increased through the rev range and the engine was running smoother.

Problem with a JEEP GRAND CHEROKEE 2.7
JEEP GRAND CHEROKEE 2.7 CRD
Excessive carbon deposits around all injectors and injector wiring due to failure of injector copper washer seals. The fault is caused by contaminated injectors causing an excessive increase in combustion pressure.
The fault was cured by using Air Intake Cleaner to soak into and soften the carbon deposits to remove the injectors and wiring; replacing the injector copper washer seals and adding Advanced Formula Diesel Treatment to the fuel tank to clean the fuel system and restore the injector spray patterns.
Thanks to Jackson & Phillips in Leighton Buzzard, Bedfordshire.
