so was looking forward to driving to work this morning and turned key and same again, just drove home last night and stood overnight and limp mode again, recovery truck out, another half day off work.
Garage were quick on job, while I was waiting to speak to service manager he was actually unplugging the TB, plugged in my old TB while in his hand ie not on car and all fine again.
Not sure on what to make of that because a new TB also does not work either now yet the factory one does, doesn't mean if I were to drive with factory one on MR200 it won't throw a wobbly but it will clear the fault codes.
Conclusion seems to be that the PCM is struggling to read data from the upgrade TB, to it or from it not sure, spoke to head tech asked about coil pack and other stuff and he is happy no other problems, there are no other fault code other than TB and PCM.
Auto Sparky going to have a look tommorrow and were hoping it won't start again for him, see if he can detect where the data is struggling. Then new PCM will be ordered, probably put the Stage 2 185 updates on then send car to Essex somehow or other, either hire a drive or low loader because I ain't taking it and will cost me day off work again, see if garage can spare a driver but then would need to be certain it will not throw up another fault during trip, so probably best have it low loaded there and back..............££££££££££££££££££££££££

I now have a Black Aygo Fire, yes a Fire edition woop woop.............
