I have posted an engine-oil query on the A4/B7 forum, adding the link here if any diesel experts are able to help!


Short version:

My B7 A4 2.0 TDi 170 DPF was serviced and filled with VW 506.01 oil instead of VW 507.00. Specialist says it is perfectly fine, manual says only VW 507.00 will be fine for DPF, what does everyone here say?
