Mercedes Sprinter EGR delete
If there is one engine that defines EGR failure in the van world, it is the Mercedes OM651. The 2.1 CDI unit fitted to the current-generation Sprinter, covering the 313, 314 and 316 CDI four-cylinder variants, has a well-documented EGR cooler problem. The 319 CDI uses a different engine, the OM642 3.0 V6, which carries the same EGR weakness in a larger unit. Coolant leaks into the intake. White smoke appears from the exhaust. The engine management light comes on. And if it is ignored long enough, the engine ends up damaged.
We carry out the EGR delete as a software-only ECU remap through the OBD port. Mobile, no strip-down, no parts to order.
This service is for off-road and track use only. Many Sprinters are used for site delivery, building trades and agricultural supply, this service is intended for those off-road operating contexts.
The OM651 and OM642 EGR cooler problem
The EGR cooler on both engines is cast and positioned in a way that makes it particularly vulnerable to thermal stress. Repeated heat cycles cause small cracks to develop in the cooler matrix. Coolant then leaks through those cracks and into the intake side of the engine. The OM642 V6 in the 319 CDI is a different casting to the OM651 four-cylinder, but the failure mode is the same.
The symptoms are consistent across variants:
Left untreated, coolant in the combustion chamber causes hydrolock or liner damage. The repair bills that follow are substantial.
What the ECU delete does
The remap instructs the engine management system to stop operating the EGR entirely. The valve and cooler remain in the vehicle but are taken out of active use. The ECU no longer commands EGR flow, no longer monitors EGR position, and no longer stores EGR fault codes.
The result is a permanent fix rather than a temporary repair. A new EGR cooler on either engine is not a cheap job, and there is no guarantee the replacement will not develop the same fault in another 60,000 miles.
Variants covered
Both the standard wheelbase and long wheelbase body options are covered. Panel van, chassis cab and minibus variants across both engines are all remappable.
