Hello, hoping someone might be able to shed some light on the latest of a variety of issues I’ve had with my 2013 l405 SDV8, 45000 miles.

On two occasions now there has been a momentary loss of drive for a split second which then comes back in with a heavy thud. Both times on motorway at around 70mph, throttle position fairly constant so don’t believe it was trying for a downshift. On one of these occasions the thud was then followed by engine cutting completely, lots of errors cycling through on dash. Coasted to a stop, would then crank but not fire. Attempted to start 5 or 6 times over 3-4 min period, then it fired and proceeded to drive perfectly for another 10 miles before cutting out again, this time with no thump/loss of drive and at around 10mph coasting up to a stop in traffic. Same issue again with not wanting to restart.

I’ve only got a cheapo laser fault reader, which stored only one fault u0401, which cleared.

Any advice on what to look at first would be greatly appreciated. Many thanks.

Hi ,does the 4x4 screen come up on the dash when it cuts out ? 2015 4.4 AB

Hi there, no it hasn’t. Thanks for your fast response.

No problem, this was the issue on mine but the 4x4 screen came up when it cut out.
