Thread: 2012 Defender randomly not starting - ideas?

Do u lock the car. If we leave ours unlocked it imbolises itself. To reset need to lock wait 30sec unlock. Then its fine. May be try new battery in key fob.

I get the noise when turning the car off... Which I think is some sort of cleaning procedure or something? egr dpf maybe?

but that sounds like an immobiliser problem. Definately something related to the electronics of the crank.

theres mention of dirty fuses and such there. And sometimes apparently weak batteries?

I'd bet it was the ignition barrel, or ignition switch. They are made of old blue cheese.... If the locking mechanism is faulty it may not be turning enough to engage the starter switch in the ignition switch. Or the ignition switch is loose or broken.

I had an annoying issue that did not reproduce for many years whilst it was under warranty (2009 110). It would leave the car stranded, and exactly the symptoms you have. Then magically the damned thing would start and be fine for weeks. Of course the dealer never found a fault int he three years this happened for. Until one day the lock stuffed up completely and you could not get the key in or our or start or anything. Well managed to get it to jiggle around and work after 4hours, but had to leave the key in the lock for several weeks until the dealer could look at it. luckily they carried out a lockectomy under warranty even though it had expired.

gee that's a blast from the past

Matt, get you dealer to call Bruce Lynton LR on the Gold Coast. Ask them what the did to fix rego 240RDU. 3 days Matt, common, try 8weeks.

Thanks for the suggestions. I ended up picking it up last Thursday morning drove it all day on errands without fault and wouldn't you know it.... Friday morning the fault was back. I rang the dealer and to their credit they came out within 30 mins (though I had left by then) and wouldn't you know it.... it started straight up. Grrrr

And it's been fine since then. I've now got a bluetooth ODBII dongle that talks to my Nexus to do my own monitoring / logging (although the dealer already said no faults are logged) He did suggest it could be the ignition barrel which I'll ask them to replace if/when it happens next.

Mine would intermittently fault.
I'd call road side assist and they couldn't get it going, so it would get flat bedded. But in the process would joint itself back into life and go. The boys at LR were frustrated because you cant fix a car that doesn't fault. So they give it back to me after a while and hey presto and it would start all over again.

In the end they replace a lot of stuff, from the starter side of things to the immobiliser side of things. Seems to have fixed it though.

btw if it konks out again and youre needing help in canberra I can help! lol

Matt

I'm with BilboBoggles on this - ignition barrel/switch. I had a similar issue with my 2012 D90 when I was out the back of Bathurst. Had it flat bedded to LR Orange, who did a great job with the diagnosis - faulty ignition barrel. Two weeks wait for the part and no problem since.
