With the introduction of high pressure diesel common rail injectors a few years ago, we are now experiencing new diesel engine problems due to the failure of the diesel injectors. It has been found that a significant percentage of failures are caused by excessive return flow from the diesel common rail injectors. This back leakage problem within the diesel common rail injectors is causing hard starting, erratic idling and lack of power. We now offer a diesel injector diagnostic kit that will enable you to perform a simple test to determine your common rail diesel injector leakage condition. Now with the age of the vehicles the next BIG problem is the removal of the injectors and glow plugs Our top of the range Pichler Injector extractors, pullers and Pichler Glow plug extractors will help. We have placed "all we know" within our section Tips & Troubles that should help with any queries or technical knowledge required.
