Does this apply to uk models as well? the garage has been having trouble with ID after replacing two sensors and eml light has come on agian after about 100 miles or so. Ive ordered one of them cheap code readers to see if I can get codes because he won't tell me origonal codes he wants me to pay to check his work?

Yes, this document applies to UK petrol engines as well. It doesn't list the diesels.

Thanks James, The car is going in to toyota hopfully to have the ECU re-mapped I think it is, I believe this should have been done first because of this problem of faulse code readings, I think I read it under the bulitins but can't find it now.
Looking at some of the threads they have changed everything 4 sensors, cat and then found out that it was an upgrade mapping of ecu needed and some done under garentee which mine being 2001 would be out now but the garage has asked me to have it done and he would pay. Hopfully this will fix my problem.
