I need help! Hot start problem!
I have a 1.9tdi PD105 which used to take ages turning over when warm. On cold start its fine, however it used to turn over for ages till it actually fired up. I had it remapped to 135bhp by Midland Remaps and he cured the problem. He said it is a common fault being a slow crank speed, so he set the ECU to send the fuel in sooner causing it to fire up first time every time.
HOWEVER! Around 10,000 miles since the map, on hot start there's been a couple times where it just about turns over and just gives up and simply doesn't start, literally like as if the battery is dead, the battery test shown that its still strong. So I have no idea what it is? Starter motor maybe?
Its like the car picks and chooses when it wants to fire up on hot start. Sometimes it turns over really slow but still fires up, sometimes there's no issues, and twice now it just hasn't started until the engine cooled down.
Thanks, Gavin
