Hello,
my Defender 110 Td5 refused to start yesterday morning - all the instruments were fine, the heater coil light came on and went out OK, but when I went to start it, the starter solenoid gave a good clunk, but the starter didn't turn.
I assumed I had a failed battery, so attached jump leads to it from my van and it started fine - problem solved I thought.
I drove twenty odd miles in it, stopped the engine, went to start it again and nothing - the same solenoid clunk but no starter action. I was pretty certain it wasn't the battery by this point, so I assumed I had a dodgy starter and went at it with the old hitting-it-with-a hammer-while-somebody-turns-the-key trick...but with no luck.
Out of desperation, I just tried turning the key a few times and on the third attempt, it started fine, although with a bit of a cough and the engine light came on. I read the codes (later, not while it was running) and the ECU had flagged a "high speed crank sync lost" error, but I think this was secondary to the actual problem and just flagged because the starter tried to cut out while the engine was still starting...which suggests to me that it's not just the starter being disabled by whatever the actual problem is.
I drove it another 60 miles, got home, stopped the engine and tried to start it again - no problems. Tried it again this morning and just got the solenoid clunk. I tried immobilising and then de-immobilising it with the alarm fob, tried the starter again and it started fine. I then moved it fifty yards, stopped it, tried to start again and just got the solenoid clunk...
The ECU isn't logging any errors, but I've only got a simple code reader and can't access the alarm/immobiliser (assuming you actually can). Does this sound like an immobiliser issue? Has anybody else had the same problem and, if so, how did you fix it? Is it possible to have the immobiliser disabled by somebody (e.g. an LR dealer) with better diagnostic kit then I've got?
Clearly my Defender can smell the snow coming and doesn't want any of it...
Thanks for any help
