VAG tar bort MPI på EA888 motorn 2019
So, it seems that VAG has decided to delete the MPI (multi point injection) from their MY19 WLTP compatible EA888 gen3 2.0 TSI models (so far confirmed with Golf GTI, Golf R, Audi S3, Ateca Cupra). This, apart from a visual check (no fuel rail or low pressure sensor in the engine bay) can be quickly verified by checking a car's engine code. All high power 2.0 TSIs have so far been part of the "CJX" engine code family with a 4th letter showing the nominal power output on otherwise identical engines in terms of hardware. (CJXG = Golf R 310 pre-WLTP, CJXA = Cupra 280, Superb 280, CJXE = Cupra 265, GTI Clubsport). The new WLTP engines have the "DNU" code, with the full R and S3 codes being: DNUE (300ps)
As some already know, MPI was one very welcome change in the gen 2.0 TSI design as it dealed with carbon deposit on the intake valves, a common problem on older direct injection engines plus (maybe not important for many but still) it allowed (as stock) hitting some big power with bigger turbo's, something not possible in the US cars that never got the MPI in the first place, and which had to go for aftermarket MPI kits to get to the same levels (think 500bhp) as their EU counterparts………

PS Orkar inte översätta, men MPI anses förebygga "carbon build up". Vet ej om man löst det på annat sätt. I US har men ej haft MPI, där är "carbon build up" ett hett ämne.
MPI - Injektorer i insuget, I US endast i förbränningsrummen, i EU har vi haft bägge.
