Hi William Your technicians were BS'ing you....;-) maybe they wanted a driver to go home in. The drive cycle takes all of 10-15 min or so to complete.
Ignition on. Idle for 10 seconds, drive to a min of 30 MPH for 2 min. Stop car leave engine running and drive to 50 MPH for 1-2 min. Stop car and switch off, wait 30 seconds and repeat above 4 more times. You have written many times in the past and it always seemed your cars in the states were different that the federal spec cars sold in the UK, I remember that you make comments about the functionality of my +8 back in 2002 that did not match the car so I bought a Rovacom and had a play and swapped information with David Poole who also had a USA spec car in the States and his was also the same as mine. Perhaps they built 2 specifications for the different markets as I have worked on about 20-25 +8's in the intervening years and all were the same as my 02 car and all sadly seemed to have the same issues. Most are known now and the fixes simple, I moved on and have had 2 +4's now (both 2008's) and must say the later car is a delight as I turn it on and everything just works which is so different than the temperamental GEMS that was in my earlier cars, I am getting much more driving fun from them and no longer carry a laptop and Rovacom interface as part of everyday life!
