hi my sprinter is a 311, it always starts perfect from cold, but when its hot ,it does not always start but if you leave it for 15 to 20 mins it starts straight away. It also at times loses power, i have fitted a new pressure switch at the back of the common rail it has improved slightly on the pulling power. any suggestions ?
i suspect its the cam sensor. this is not fault monitored, so doesnt show on a download. very sensitive to heat. only needs it to start, so it pack up while running, but you dont know until you restart.
bet that fixes you!i should sting you for this rare snippet, its a pig to find if youve never had it!
