I wouldn't worry about a difference of 0.4 ohms - that's indistinguishable to the ECU
Annoyingly, I can't find in the 5th gen manual what the correct resistance is - the injector section just shows how to replace and in the fault finding section, it just tells you to listen for a click and/or swap/replace with a known good one
The 4th gen manual gives the acceptable resistance range (1.5-2.5 ohm, btw) but that's not relevant to the 5g because it uses different injectors (doesn't have the in-line resistance box that a 4g has, so I expect probably has higher resistance coils in the injectors). Frustrating that the 5g manual is missing this info.
