My 2008 Arnage T has "failed to proceed" Fault shown on the display is EPC Throttle Control. The car starts, idles for a second then stops. Pushing the throttle to the floor and starting it with the throttle held down makes no difference other than the car goes straight to high revs then shuts down. The fault is intermittant, it'll stay imobilised for a few days then miraculously start and run fine. The car has a Bentley Heritage warranty, was returned to the supplying agent JCT 600, but they claim no fault codes have been logged and that is has started every time with them. Any ideas gratefully received-thanks

The car still continues to start without hesitation at the dealers - jinto 100, i'm guessing if this was down to an immobiliser gremlin, the car wouldn't start at all, It did start but shut down after a couple of seconds- thanks for the input guys

Update- Touch wood, the car hasnt broken down since, so it looks like the battery (passenger side) was the the culprit. Think i'm right in stating the passenger side (uk cars) battery runs all the brain power while the drivers side just cranks the starter ? While i'm on the subject, does the integral charger socket in the boot charge both batteries ?

Thanks for the info jeyjey. Anybody know the average time taken by the quiescent drain before the car plays up ? In other words, how many days should i be able to leave it without a charger, assuming the car just stands-thanks
Edit- my car has a tracker so i assume this will make matters worse

I'm wondering what the milli- amp draw should be per hour ? I have seen similar before on Mercedes SL, same system, two batteries but when the Mercs were playing up, going flat after a few days it was because the car was doing something it shouldnt. I can't believe Bentley or anyone else would release a car with a system so flawed the car is unusable after three days. There must be an acceptable cut off point the draw shouldnt go above-mA/hr rating
