Feel free to look for other possibilities. I'll take my opinion (as a qualified mechanic by the way) and feel free to NOT provide them to you any longer if you like

FWIW, I can't see how you believe that my suggestions (fix it PROPERLY with the RIGHT tyre sizes, use the original wheel tyre package which had - by the way - the RIGHT tyre sizes, or put up with the problem) have anything at all to do with the progress of motoring technology.

The delusion is strong in this one LOL

I gladly accept your offer to not reply to my post.

No worries mate, you can feel free to ignore anything else I decide to post in this thread or any other. that is your free choice and always has been.

Of course, there are people out there in this community that are intelligent enough to understand that when factual information is provided, even though they may not like the answer, it doesn't change the facts of the situation. I don't count you among those.

And when you finally work out that the only way to solve the problem you are now experiencing with your vehicle is to run the right tyre sizes, the you might think back on this thread and remember what a prat you were

You probably won't like to know then, that the reason you are getting this error is quite simple - wheel speed sensors measure the rotational speed of each wheel. These are compared in almost real time, and when travelling in a straight line, the vehicles programmed logic can handle reasonable rotational differences before the ESC program begins to apply brakes, reduce power etc. When cornering however, the arc transcribed by each wheel is unique - and each wheel travels a different distance - a relatively small difference in tyre rotational circumference can THEN be effectively multiplied to a degree where the ESC believes something is not right based on such factors as steering angle input (on an X radius corner, the ESC is expecting each wheel to rotate within a certain tolerance level), lateral slip is not being detected by the lateral G sensor, so the ESC says 'enough'.

Inconvenient facts which you can ignore all you want - but I am sure other intelligent members of the forum may appreciate if they require the information.

And it can all be solved by running tyres which have the same - or near identical - rolling circumference. Which yours do not. And you are experiencing the problem.

Unless you are a dab-hand at reprogramming ESC logic of course.

But then again, I might NOT. Your snarky Brit humor is easily confused with arrogance. Perhaps this is not your intention, but the written word lacks tone and inflection.

Brit humour?

Wow dude, your understanding of geography is as lacking as your understanding of tyre sizes and their implications for vehicle system behaviour.

I am from Australia. Kind of the other side of the world from Britain.

But settled as a Brit Penal Colony.

Actually no - settled around 50,000 years ago by people who migrated down a land bridge from Asia.

More recently, yes, most certainly settled as a British penal colony. Something that many of us "First Fleeters" (those who can trace our anglo history to the first colonising fleet) are rather proud of, so your laughter is kinda lost on me. You may think its "ROFL" but I'm proud of my heritage so... meh.

Regardless, your "Brit humour" comment makes no sense at all. But then, based on what I have read from you so far, I guess I shouldn't expect too much.

It's fun though, engaging with people like you. Reminds me of how fortunate I am.

Have you digested any of the information I posted about the logic of the ESC system yet, or are you struggling with the big words?

Not struggling with the words...only the spelling.
