They were replacing the 0W40 "European car formula" with 5W40 "same" (which for me is a good thing). The real key is to look for Porsche A40 on the back. Or of course, don; worry about it since a significant part of most approvals is paying a fee, filling out paperwork, and going through testing that you have already completed for someone else.
The 0W40 was always shaky on the HTHS test that is the core of ACEA A3, presumably due to its wide viscosity range and thin base number. Street drive car - meh. Track driven cars - meaningful.
But the key is A40. If you want PM/email me and I can send oyu a presentation on A40 from BT lubricants research labs
