examiner refusing to take a test because of a warning light?

hi, ive got my test in a few days and recieved an email from DVSA just now about what things might make an examiner fail your test. one of them was any warning lights on the dashboard.

I’m using my own car for the test, and there is an issue with the tyre pressure detectors or something of that nature that makes the car think the tyres are far too low, and making the tyre pressure warning light come up on the dash. there is actually no issue with the tires at all, and all maintain pressure well, it’s just the car that thinks they’re too low.

is this likely to get my test failed?
