Hi guys,
I'm having starting problems with my 2009 TD4. The issue is that after inserting the key and pressing start, lights on dash go off, and it doesn't start. It looks like the fob switch "hungs" since it's not easy to release the key. Pressing start only (no foot on brake) causes a normal operation of lights on dashboard, but when trying to start it, it fails and lights go off.
After a while, it finally starts. Trip and all fuel consumption values are reset.

I did a search on the forum and found a technical bulletin talking about a software update, but that's supposed to be related to 2007/2008 vins. Can this software update be missing on mine, if it's 2009?

I scanned and got these errors:
B108D-23 Start button (circuit C)
B1D21-62 Remote control switch
U3008-01 Control module

These errors are related to the start button and the fob docking thing. But of course so far I have no clue of where the issue is. Any ideas before going to LR? Their suggestion will be to change everything

Thanks,
Juan

Is the battery charged and are the connections clean and tight ?

Battery would be my first check. Happened to me years ago on my old FL1. Everything went out when I tried to start the engine. Battery completely U/S.
The same has just happened to a chap at work this week with a VW Touareg (at least with a FL2 you don’t need to take the seat out to access the battery like he did).
Best of luck. Gone:
2002 FL1 TD4 GS Zambezi Silver
2007 FL2 TD4 GS Izmir Blue

^ As above ^
I'd say almost certainly a faulty battery or loose/corroded connections, I'd start at the battery earth connection where it connects to the body.

Read up postings on extra Earth Cable. FL2 MY10 TD4 GS traded in at 2 years
FL2 MY13 TD4 GS Current

Hi guys, thank you for your comments.
Battery is not the issue. It's new, less than year, had it checked and it's fine. And in fact the engine starts up every day with no issues.
Same for the extra earth lead. That's in place and ok.

The issue is intermittent. It happened only twice in the past two years.

Based on what I found here, symptoms are the same ones solved by technical bulletin LTB00093, but this is supposed to affect only 2007 and 2008 vins, that's why I don't have a clue.

Update on this issue... so far, it never happened again. The only thing I've doing differently is to wait a couple of seconds before pressing the brakes and pressing the start engine button.
No new faults were recorded.

Still puzzled about this...
