Q8 3.0 TFSIe EA839 PHEV variant availability

[Gravity909]

As a long time JB1/JB4 user on TTs, BMWs and 43s, I have a Q8 3.0T PHEV incoming (I think its a variant of the EA839 engine?). is there or will there be a JB4 for this engine too? I'm confused about hybrids and tuning, not much on the subject.

TIA

The Group 7 Jb4 found here will work on it: https://burgertuning.com/collections...audi-s4-s5-sq5
The TMAP plug circled in yellow below is a bit hard on this model to reach.

Thx George for the quick reply. Is that Group 7 recommended and/or been tested on this engine configuration specifically? I saw it was listed as a fitment for the Q8 55TFSI which is the non-phev engine I presume? Just apprehensive with the mild Hybrid EV additions and what implications it might have, if any.

I also can't find any discussion / install of this specific engine/model on the following forum:

Thx for your input.

George, can you confirm the Group 7 is suited and/or tested on the PHEV TFSIe version of the EA839 engine?

The PHEV does not affect the way the JB4 works. It adds power to the motor side and PHEV works independently.
