Try this. Extract the NU5T-14G381-AA update to your USB drive. Now overwrite just the autoinstall.lst file from the Interrogator_AB package from the troubleshooting page, open it with notepad and change this line: Open1 = SyncMyRide\GB5T-14G386-AB.tar.gz to Open1 = SyncMyRide\GB5T-14G386-AD.tar.gz So you are just changing the last letter from B to D. That will just run the XML generator, but it's the newer version from the update package. If the Ford site still won't accept the XML, try doing it from a different browser.

The update must be installed fine if the about page says 22200, it's only the log file you are having an issue with. Try the log troubleshooting steps here, no need to reinstall the update: https://www.ford.co.uk/support/how-tos/sync/sync-updates/how-to-troubleshoot-sync-update-issues

It usually just comes up on the screen saying to service now when the oil life runs out. I think it might warn you at 10%, or maybe 5% I can't remember. It's usually worked out on a combination of time and type of journeys/starts and based on readings from various sensors.

If another key is detected in the car it’s not supposed to allow it to lock.

Not the problemed cam wet belt no. It’s chain in the mk4. The oil pump is still belt driven and while that’s not known to cause issues, I’d still avoid engine flushes.

Yes but my point was that OP said car is starting even without the key in the "dead key" spot. If the key battery is dead, it will not be broadcasting its rolling code to start the car and the passive chip cannot be read from any distance, so it's not that which is allowing it to start either. EDIT: With keyless and a working fob battery, the passive transponder is not being read. It is reading the code broadcast from the key instead. The passive chip only gets read when the key is in the "dead key" position. The car cannot detect the passive chip otherwise.

If the battery in the fob is dead as OP says, then the transponder can only be read passively when it is in the "dead key" position. It works a bit like NFC, the power to wake the passive chip is very short range.

It's supposed to be held down in the middle by a screwed clamp. And is it Fiesta or Focus? (Although they both use similar clamp)

The black antenna was just a model year change at some point. Probably saved ford a few pennies not having to keep an inventory for different colours. They are all built like that now.

Did your garage use engine flush?

It's because the bulbs with built in resistors are sold as high resistance, it threw me and flipped what I remembered 😅

Do you have a dashcam?

Walking increases your CO2 output.

Only the 2.0 Ecoblue The older 2.0 TDCi is a chain.

I think what doesn't help is that a lot of the LED bulbs are cheap tat from China that UK shops sell as their own. It's hard to know what you are getting and one person could have a good experience with some decent ones on one occasion, only for the bulb to change next time it's ordered.
