The check engine light came on and the code reads PO52e. Mercedes has a Intake Line Assembly Extended Emissions Warranty (Code P052E) up to 150,000 miles. They’ve admitted this was a problem with this engine but only covers 3 other vehicles with the identical platform, & excluded the Mercedes Metris

It has been two years after posting an issue with engine light on indicating the error code p052e which is a known problem on many models mercedes has. This metris van is not a passenger van but a commercial van. It has however the SAME engine and SAME error code as all the models mercedes having this engine. It is stated that it is under warranty by mercedes up to 150k, with the exception of the commercial van. This is ludicrous and a failure to correct a known defect and expecting the customer to pay the bill. It is also disturbing that the federal safety agency does not communicate to the complaint or direct mercedes to FIX the problem. What happened to Quality and Customer care?

2016 Metris Engine M274 Check engine light, P052E71 Crankcase ventilation valve- Oil leakage- safety is compromised as this damage causes engine failure. The dealer has confirmed multiple oil leaks and other parts and service is required at extensive cost to me. This is the same damage and failure that passenger models with the M274 engine have an extended warranty available to them- my PASSENGER Metris with the exact same engine is excluded from this extended warranty.
