This is a common prob what was the fault code logged ?there are 4 sensors on these cars 2 on each bank upstream and downsteam the issue is the ecm tries to compensate for one bank that is out of limits using the fuel control of the other bank to try and keep overall emissions within limits.this makes diagnosis difficult without proper diagnostic equip.at the last count genuine jag. sensors are EXPENSIVE and cheap pattern ones are not that good.advise. find someone with jag diagnostic equip. identify the problem

Hi
I cant tell you why but I do have a solution for you to try, I had a similar fault on a fiat punto last year, I disconnected the battery for an hour and then put it back and the car started, Im still puzzled by this but It may work for you, worth ago, make sure you have your radio code before removing the battery
Hope this helps
Regards
Dan

There is a reset tool that you will need to purchase. Check some of the BMW forums online or E-Bay to purchase. Many people will recommend shorting pins and starting car etc--it's not worth the trouble. Buy the tool.
