Bought a new Bosch S5. Trickle charged it overnight to make sure it was fully charged. Fitted it according to the instructions in the Wiki.

Drove about 50 miles with caravan on the hook. (I might add here that I still got the air suspension inactive - HDC fault after about 15 minutes of driving, more work to be done there). Anyway, car not used for 2 days whilst on site, tried to start it today, Feck all. WTF . I am becoming so pi**ed off with RR ownership.

I love the car but the constant faults are ruining the whole experience.

First check would be the FSR (Final Stage Resistor), being notorious for draining batteries in the older FFRRs.

Also suggest to do a drain check on the battery, there may be other users that don't switch off as they should. MY 2010 5.0 SC Galway green and sand interior!!
Have the Faultmate MSV2 Extreme to be tinkering with the settings etc. !!
