EGR faults need a compliant repair path

EGR systems can create poor running, smoke, hesitation, DPF issues and engine management lights. The question is whether the valve, cooler, sensors, control system or carbon contamination is the actual cause.

LT Servicing diagnoses and repairs compliant EGR systems, with repair, cleaning or replacement advice based on evidence.
