What is the EGR cooler and why does it leak?
The EGR cooler is a heat exchanger that cools recirculated exhaust gas before it re-enters the intake. It consists of stainless steel tubes surrounded by engine coolant. The thermal cycling from cold starts to hot operation gradually stresses the welds, and the carbon-rich exhaust gas coating the tubes accelerates corrosion. BMW N47, VW 2.0 TDI, and Volvo D4 diesel have well-known EGR cooler failure patterns.
Can an EGR cooler be cleaned or does it need replacement?
70% of EGR cooler failures at GarageNation are from soot plugging the gas passages — cleanable at ₹8,000–₹15,000 with ultrasonic and chemical methods. 30% have a physical crack causing coolant leak — these require replacement at ₹18,000–₹35,000. Coolant leak into intake (white smoke) is always a replace-immediately job — running with coolant in the combustion chamber causes hydrolock.
