Technofile: Opus IVS overcomes blocked DPF

OPUS IVS OVERCOMES BLOCKED DPF

Opus IVS reportedly delivers beyond the scope of general scan tool diagnostic capabilities

IVS 360 OEM-Trained Master Technicians recently assisted a customer with a BMW fitted with a M57TU engine and automatic transmission suffering from a blocked DPF. Opus IVS says its IVS 360 Live Repair Guidance support service provides unlimited and unrivalled support to workshops globally. Customers have access to the IVS 360 team of OEM experienced, factory-trained master technicians. It says not only does the team help you establish the fastest, most reliable, and accurate diagnosis, they actually take you through the process stepby-step, all the way through to vehicle repair. Ultimately, workshops have access to a team of ‘behind the scenes’ OEM brand-specific technicians that they can rely on daily to provide the actual fix. Ultimately, IVS 360 provides technicians with the confidence to repair the most complex vehicles fast with live repair guidance. The IVS 360 team often sees multiple cases of the same nature. It says this is particularly true of BMW vehicles fitted with the M57TU engine and automatic transmission which results in a blocked DPF. Fault: DPF will not regenerate. Cause: Engine over cooling, even after fitting main and EGR thermostats. The Fix: Retrofit an additional thermostat. BMW cars fitted with the M57TU engine and automatic transmission often suffer from a blocked DPF. Diagnosis has been carried out and during a test drive you have noticed that the engine fails to reach over 68 degrees Celsius (approximately). When left to idle, the engine temperature can be seen to increase. This indicates a thermostat that is sticking open. The normal repair of replacing the main engine cooling thermostat and EGR cooler thermostat has been carried out and a test drive has been undertaken to test the operation of the cooling system. However, once again the engine temperature fails to exceed 68 degrees Celsius (approximately). The cause can be the automatic transmission oil cooler thermostat stuck open. A test to prove would be to clamp off the pipe between the cooling system and the automatic transmission oil cooler then repeating the test drive. The automatic transmission oil cooler thermostat is not available separately from the cooler, however there is a work around - purchase an inline thermostat that is available from the VAG group or many of the main aftermarket parts retailers (Part number = 4e0121113.)
