Interesting.....I took mine into the local MG dealer's last Friday to check that the "locked-in" recall wasn't needed on my car (original dealer where I bought the car said the mod had been installed before I picked it up, but the MG Recall site said that it was needed).
Upshot was, the yes it apparently WAS needed, so the local dealer installed the mod and updated all the modules. They all now "display a green cross, which indicates they are the latest update".
I drove away and was pleasantly surprised that the LKA was now reduced to a "beep" and a hint of pressure on the steering rather than the unpleasant wrench I was getting before.
Forgot to add, the whole point of this post was to say that when I got home, I was surprised to find that my Infotainment system was still at R30. So, what does R33 bring to the party?
