On a 2011 CGLB engine (2.0, 170HP) at 102.000 km the EGR was broken, the water penetrate in the air intake but not in a big quantity. The EGR was changed with the recommended version from ETKA 03L131512DT (OEM part from Valeo). In 100 km the EGR was broken again with a lot of water spread as steam more than the first time. The auxiliary water pump is working at an appropriate debit, the DPF seems not to be clogged, it is in good condition after a static test. I am not sure about the differential pressure sensor, if it is decalibrated and the DPF has a lot of soot, the pressure of the exhausted gases is at a high value and can broke the cooler so I will try to test it. Is it another possible cause to such a fail in only 100 km?
