I own a 2011 Tiguan 2.0 Tdi... It used 2 litres of oil with a recent (2400km) trip... Most of that oil ended up on my trailer behind the vehicle

I've been under the vehicle and removed the belly plates... The oil seems to come from somewhere behind the engine, under the DPF... This is where the EGR cooler sits... The leak does not seem to come from the turbo oil supply/return lines...

Could a faulty EGR cooler cause this amount of oil leak? I did not use/loose a drop of coolant, just oil...

For me to try and pin point the leak, I will need to remove the DPF, which is a HUGE task (drop sub-frame and remove driveshaft)... And only then I would be able to see what parts I need...

If I know for sure it could be the EGR cooler, then I could buy one before I start to strip...

Vehicle has 185k km.

Any suggestions as to a replacement EGR cooler ?

Thanks
