Timing chain
The diesel particulate filter (DPF) clogs relatively easily in diesel engines used for city driving or short trips; this prevents regeneration, leading to system warnings, power loss, and in advanced cases, failure.
Exhaust Emissions
The EGR valve and cooler can clog with soot and carbon deposits, causing rough running, power loss, and engine warning lights.
Exhaust Emissions
When oil maintenance is irregular or incorrect oil is used, the turbocharger can wear prematurely, leading to performance loss, abnormal noises, and in worst cases, oil leaks and exhaust smoke.
