Other Fuel System Related Problems of the 2019 Mercedes Benz Metris

Other Fuel System problem

The pressure relief valve part on our mercedes van is causing a check engine light to go off with code p052e. It's a known issue on several mb models (glb, c300, etc. ) that this original part wears out and can potentially cause an under-hood fire if oil gets clogged up in the components. To my knowledge there is no routine maintenance that we missed that would be causing this issue. Mb has since released a new style of pcv part with insulation wrapped around the hose to prevent condensation build up. It's not possible to get the original stye of that part that is installed on our van anymore because mercedes knows the part is poorly constructed and will fail. It's a costly and laborious repair (5-7 hrs), yet it seems like they already know it's a widespread and serious safety issue, however there is no recall on it on the 2019 mercedes Metris as of now.
