‘04 TD5 ES Auto.
Had a weird one today, yesterday I had some welding on the back left of the chassis (unsure if this is relevant) so left refuelling longer than normal (the fuel light came on about 3 miles before I got there) so that the tank was near empty in case it had to be dropped. It was driven home (about 13-14 miles) without issue and without refuelling). I don’t consider this enough to run out of fuel (?) Today, a mile from home going to get fuel the truck just died. No warning, no rough running, just died. And it’s an Auto so it wasn’t me stalling it and not restarting. It would crank easily but no attempt to start. I got towed to the pump and filled it up (97 litres brimmed). Attempted to start (failed but cranking easily) Did the ignition on, depress throttle 5 times, sit with engine management flashing for 3 minutes thing to purge air. Attempted to start -sluggish crank twice then solonid just clicking.... left truck at the pump and walked to Halfrauds and brought a replacement battery and started first time....
What am I missing? I thought a diesel will keep running without a battery once running? I know the TD5 won’t start if the ECU sees less than 10.5v when cranking but would this cause it to die whilst running? Was this a simple battery failure even tho there were no warnings or sign prior to the initial engine stopping?
New battery once installed is at 12.5v engine off, 14.2v at idle, 14.1v at idle with main beam, light bar, heater fan @ full & both front/rear de misters on so alternator appears to be charging fine....
