Hi, Today i drove round town and was fine, the accelerator respond as normally, definitely was no the callipers. (I checked that yesterday) @steve2006
I just booked with Lexus for a service do in a few weeks so if it has stored codes in the memory will Lexus know if is the 12 Volt auxiliary battery? or is another problem.
The mileage is only 27.000 @Initial P
Thanks you all.
