Hi,

It's been a long time since I posted here. My 2013 Passat TDI now has 380k kms. It's been leaking oil for some time so I decided to fix it. Can anyone point me in the right direction as to where the leak is possible coming from? I don't have a check engine light related to EGR. The leak appears to be coming from somewhere near or at EGR cooler. Thank you.

Let me know what you find. I have a leak in that area as well, which I am attributing to a leaky valve cover -just haven't had time to replace it yet (have all the parts). I did check around the cam seal, as these are known to fail, but it looked good.

After careful analysis, I am concluding that the oil leak is coming from a leaky valve cover. It leaks down the engine wall, bracket to DPF and into the EGR cooler as well. I also discovered a leaky exhaust egr pipe in the process.

Things to do....leaky valve cover + leaky EGR pipe exhaust + timing belt + leaky DEF at injector/line.....seriously considering delete....

Changed the valve cover gasket this past week. No oil leaks anymore. Car would leak oil right away before fix.
