Toyota Auris 2009 MMT Flashing N & Clutch Actuator Problem

[BoltonAbbey]

Hi

I bought a Toyota Auris 2009 MMT (multimode transmission) from an Autotrader dealer on September 7, 2023. Just a week after the purchase, the car showed a gearbox issue, and the auto electrician found a P0810 issue on September 15, 2023. When I inquired the dealer about the car's condition before the purchase, he assured me that it didn't have any issues. However, my wife and I have been stranded on the road several times due to the Flashing N issue. The car was stuck in N mode and not moving. My wife felt panicked and found these breakdowns to be life-threatening. We captured the symptom we struggled with in the following video.

 

Frustrated after failures to fix the problem at the local garage, I paid £144 for an inspection at Toyota RRG, and they recommended changing the clutch actuator, which would cost £2,000. Realizing I could not afford such a high repair cost, I took my car to the local garage once again, and the mechanic found that the actuator's motor is not the correct one. He is now searching for the right one in the aftermarket. Over the past four months, I've wasted a lot of time trying to figure out the problem. My car is still in the garage, and my wife and I are using a taxi to bring and pick up our child every weekday. I am angered that the car was not thoroughly checked before being sold. Is there anyone here who has experienced the same issue or has advice on it? I am getting worried whether the issue can be fixed. I have been surprised that there are not many mechanics who can fix MMT.

Why not return car to dealer to fix or refund?

Personally i stay well clear of any automated clutch gearboxes.

I have heard that the carbon brushes can wear out. Can they not try taking the clutch motor apart and checking/ finding suitable replacement brushes?

I reckon the best thing to do is utilise your consumer rights and get the dealer you bought it from to fix it or give you a refund.

We aren't big fans of the MMT gearboxes as they have proven to be a black mark on Toyota's general record of reliability, and as you say not many mechanics know how to fix them properly.

A lot of the time, esp in older cars, it's just a case of the clutch needing changing, as it's basically a manual gearbox, but most places end up changing everything except that. The system also needs calibrating when anything's changed which hardly anyone seems to know how to do.

If you need to get it repaired. Find a mechanic with toyota techstream as there will be a utility for the calibration procedure. If they dont have techstream, avoid them
