the audi EA113 2.0T is the biggest offender of all when it comes to CBU, then the 1st gen ea888 engine.I know they have it since 2005. They also had IS250 since then which is biggest offender of all when it comes to CBU.
BMW since N54 doesn’t have those issues nor it is necessary to go dual injection. N55 while nit having Atkinson cycle, don’t have CBU issues nor N20.
B46/48 and 58 do have Atkinson cycle, but I would say for different reason.
