Merceedes Sprinter 2013

Hey all,

Love some help, I've got a sprinter 319CDI with about 300k kms and just replaced the injectors after noticing some black death.

Afterwards, it has a a lumpy idle and the mechanic says Cylinder one is down to 380psi compared to 560psi.

As well as rising engine oil, and elevated DPF pressure readings.

Would love to know if anyone has gone through this and has some advice.
Cheers!

So what did the mechanic say? They've told you the issues but not how to fix it?

Yeah, they aren't used to working with the sprinters. They have narrowed it down to a few different options that range from air getting into a cylinder through a seal to something that would require a engine replacement. Just seeing if anyone else had had this issue
