Mine's been doing that for ages! Completely random, though usually when starting from cold.

not sure about the shutting off - but the key issue, is it an old one with the paint wore off etc? I noticed ours was doing the same - just didnt feel smooth anymore and i had to pull it out at times. Totally unrelated i got the spare key up and runnign again - that dodgy battery connection sorted. Anyway it now works 100% fine.

In cold weather mine also does that dip in revs shortly after firing up, but it nearly always catches itself just before it stalls. A couple of times it has let me get out and start scraping the windscreen before deciding to stall, but it is very rare. It's done it as long as I have had the vehicle and through two cycles of replacement fuel filter at service and one replacement battery. I've always assumed that the software is doing something clever around that point when the engine is warming up, heater plugs are cooling down etc. and that at times it simply doesn't quite get it right. I do find that all these minor glitches seem to occur much less often if I boot-up the system before going for ignition. 2005 D3 2.7 Auto

Mine also dips out momentarily after it first starts. This was a pain when the engine was broken, but now its running mostly ok, it doesn't stall. Hyundai Ioniq 5 Ultimate. The family car.

Will try the spare key,. The one I use is about 4 years old. Noticed that when the engine cuts out the immobiliser light switches on. Could be stanadrd procedure but can also indicate a key problem. |

Thanks Worms, not sure if it is the cold. We had 32 on the clock yesterday here i SA and also a while ago since I scraped the wiindscreen. Will try to give it a few secs between booting up and starting, let's see if that helps |

Hi Willem, I have exactly the same issue with the engine cutting out directly or soon after starting. It started about two years ago - twice within a month, and then nothing for the next 2 years. It has now re-surfaced again, 5 times in 2 months. I don't use the car every day. Sometimes it dies directly after starting. I normally reverse out of the garage without using throttle, select drive at the end of the driveway, and idle towards the main gate which is only 30 metres away. It has died at the gate about 4 times. It takes about 15 seconds to get to the gate. It re-starts normally. It has only ever died once in the traffic after an extended idle at a long phased traffic light. At every other time it dies immediately after starting, once after about 2 secs after engaging reverse, the rest after about 15 secs. Each time at idle. An important point I noticed today when opening the windows from inside without starting the car: Put in the key fob, press the start button without my foot on the brake. All the normal dash lights came on and then went out immediately. the only light remaining is the 'key docked' light. No Immobiliser light. Thinking back, the dash lights remain off after the engine cuts, indicating the engine hasn't stalled. The connection is simply 'lost', but I don't know which connection? My gut feel is the ignition module that takes the key fob. So the relationship between the engine cutting only at idle or after start, and the ignition cutting even without the engine running is confusing.

No, really... Read here: https://www.freel2.com/forum/topic17379.html P1259 Immobilizer to powertrain control module signal error Which is consistent with the engine cutting out. P061B Internal control module torque calculation performance Also consistent with an engine cutting out, although it can appear on various other occasions. IMHO, the sequence of events was: P1259 -> Engine off -> P061B |

Thanks Alex - Yes, you are exactly right. Fault codes P1259 and P061B appear on the diagnostics printout from my friendly Land Rover Mechanic.

Just a quick update: I went to the Land Rover dealer closest to home. As always there is a constant turnover of Service Managers. The latest guy was young and extremely helpfull. He was also very clued up on the FL2. After 90 minutes of discussion in front of the manufacturer troubleshooting procedues, it does seem that the P1259 error would most likely be generated by the Central Junction Box (CJB). This box gives the feeds to the main engine ECU as well as the Start Control Module (the box that the key fob slides into). The clue that makes all the difference is that the dash lights go off when the engine cuts - and that cannot be caused by the Start Control Module.

Had this problem on my wifes VW, it turned out to be the immobiliser so I had it deleted from the ECU, problem sorted. |
