2016 Mercedes-Benz Metris: check engine light

Filed Oct 10, 2026 · Engine, Transmission · IL

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.

Engine on and vehicle parked for 10 minutes with parking brake applied. Leaving from a parked position with engine running, parking brake released, I shifted from park into drive but the vehicle showed I was still in park. Could hear transmission shifting from p to d and to r but no information feedback. Eventually I found that I could engage in reverse, neutral, park, and drive but only park was showing on display. I tried restarting the van but it didn't change. Received errors for turning car off while in drive even though I was in park. I ended up driving with the car in "park" for about 100 miles to my destination. During the drive, there were lots of errors mainly the speedometer would not work ( had power but only said 0 MPH). The tachometer remained at ~800rpm regardless of actual RPM. The gas gauge wouldn't work. Numerous errors occurred with the active braking system (alarm only). The SRS defective indicator remained on the entire drive. When I reached my destination (gas station), shifted to park. I turned the car off again and completely disconnected everything electrical and let the van sit for ~5 minutes. The errors cleared when I restarted and the speedometer/tachometer/gas/SRS all worked but I had a new check engine light activated. The only message was still related to SRS but the cel stayed on even after acknowledging the service message. After about ~200 miles and 3-4 restarts the cel cleared and everything worked properly for the remainder of our trip (about 1000 miles round trip). Later, I was able to recreate a similar system malfunction when applying the parking brake. I've since been able to conjur random errors all related with safety systems and the park/drive/reverse scenario 50% of the time after applying and releasing the parking brake. The errors only happen after activation and release of the parking brake (so far to this day).
