Hi Guys,
Need some help with a diagnosis, Im finding Im having a problem with oil consumption with my A6 TFSI (BPJ). I understand this is the A4 section but there are more A4 owners than A6 owners with this engine so hopefully you guys can help out.
I have a feeling the PCV could be part of if not the cause, but do realise these drink oil due to design. Just need to check a few things as theres conflicting info elsewhere. Car runs beautifully and pulls hard when turbo kicks in with no smoke.
When cars started if I remove the dipstick briefly I hear a hissing sound. With car started I open the oil cap (dipstick in) and as I lift the cap I can feel quite a strong vacuum at idle.
Is this sign of failure or correct?
Does anyone know if the silver crank breather pipe has a check valve in it like the MKV GTi?
Thanks in advance
