Waiting to hear back from the dealership on the issue with our 7.5 Golf R Wagon.

Early comms doesn’t look good…” “Cylinder 3 misfire was found, swapped around spark plugs, fuel injector's and ignition coils.
Misfire was still evident, carried out a compression test on cylinder 3 and found to have 40 PSI.”

So, worst case scenario, if I need a new engine, is there anything I should look to add/modify at the same time? The rest of the car is stock, and only done 77K
