So experienced my first breakdown last night, after only 1 week of ownership! Not me, the car! ... although I wasn't far off !

The recovery guy spent 4 hours insisting on checking the usual suspects, battery, fuses, starter motor, onboard diagnostics.... with no luck! He put it down to an "alarm / immobiliser issue". Then he agreed to recover my Crossfire to my home address.

Symptoms were, ignition came on as normal, but fan running at full speed, plus no start / engine didn't crank.
First thing this morning, I carried out the RCM solder fix. Car then fired up as normal. Big relief.

There are a few other common known issues, such as the crankshaft position sensor failing. Might be worth replacing this part for new now, as preventative maintenance!
