Resetting service warning lights

That could explain the brief open wifi alert I used to get on my phone a few years back when a certain car passed me in the other direction. It certainly wasn't location specific.

It was a testable item.

Testers, IME, just check to see if the light comes on and goes off.

I'd guess some may check it operates correctly. The ones who like to drum up business. Or just super keen.

Or the ones that do the job correctly. Some people do actually do a proper job.

Its fine, you aren't the only one to get it wrong, the rest will just continue to deny it.

The first post in the thread made no mention of "disable" it just said "reset" and "turn off" ....

Without bothering to fix any fault that may be there.

I wonder if you could simply rip out all the airbags and pass the MOT that way? Then the fact that the light is on would simply be reflecting the true position!

For a real oddity. A number of times sailing from Portsmouth to Caen or St. Malo or in the opposite direction, I have left my phone turned on so that I can check the time in the dark and about half way, the phone has connected to a phone network and given me the message "Welcome to Iceland." WTF?

operate a really, really good free wifi service?

So if the fault still exists the warning lamp will come back on. Which proves it's a real fault and not some spurious one off triggered event from going over a pothole a bit fast last month.

Interesting, but it wasn't wi-fi, but a mobile phone signal. The message was similar to the ones you get whenever you enter a country and your phone "roams".

Sorry, my mistake, as I see now you did make that clear in your original post. Perhaps then a passing cruise ship with a picocell provided by an Icelandic company. The only people I know who cruise regularly have told me (repeatedly!) that all mods cons are available, including mobile phone signals. I suspect might be rather pricey though as the EU ban on roaming charges doesn't apply in international waters.

That's okay.

That was my thought, but it still seems odd that it has happened in both directions, in different months and years and at around the same part of the crossing.

I think that it is just one of those things that we'll never know the answer to.

Don't worry. Once we're finally out of the EU all that erroneous s**te we've hitherto had to put up with will be history.

Not if they fix it so it doesn't come on which is what the OP wanted.

Yup. The phone suppliers will be back to making you pay for any such information. Or even conceal it so you run up a nice large bill without knowing.

A price well worth paying. ;-)

Well it's easy to fix the light not to come on. Remove the bulb. That will fail the bulb check.

Stopping the OEM ECU generating and storing the code requires a huge skill set.

Easier to program a "PIC" chip or PI Atom to do the right light sequence. So as he has a market of ONE (it would be very illegal to sell), the OP now has to become an electronics and computing engineer.
