Any thoughts??? and where is exactly is that sensor located?
I assume this is the crank angle sensor which is located next to the crankshaft pulley. To get to that area, you need to remove the drivers side wheel, remove the plastic inner wheelarch protectors. Next to the main crankshaft pulley you will see a sensor close to the teeth on the pulley, it basically senses how fast the engine is spinning based a signal generated every time the engine spins 1rpm (that might not be the best explanation but the gist is right)
Believe me I have been around the block when it comes to fault finding niggly horrible problems with the Alfa 24v V6 engine and my advice is phone your dealer and ask cheerfully to speak to the service manager (if he is "busy" ask for a callback.) Explain to him that they recently had your car in to investigate a niggly fault for a non start situation and you were charged £x to fix it with the solution being "it was a loose connection", the problem, however the exact same problem
is still there so you think it is reasonable for them to take another look at the car FREE OF CHARGE and see what the problem is.
If they are half decent they will go for this and while you are there you can ask them what the diagnostic machine said. If they do not go for this then never deal with that place again.
Let us know how you get on
