I' m no vehicle mechanic and possibly slightly off topic but can someone please explain how Audis oil loss figures of a liter per 1000 miles is acceptable. If a modern engine is losing oil it must be either leaking or burning it.
If its leaking then thats a big dirty enviromental mess and if its burning it then surely its either leaking past the piston rings (loss of compression etc), going through the turbo (eventual engine runaway once it starts to get enough oil to fuel the engine through the turbo and become self sustaining) or burning it some other way probably leading to early DPF failiure.
Sounds like a manufactureres get out to me for a ×××× engine design and either way a pretty unplesent experiance to anyone behind them and an expensive eventual outcome for both the owner and the enviroment.
Edited having discovered the Audi engine in question is petrol and not diesel. Most comments still apply though.
