Engine sputtering at idle

Hello

Only day three of ownership and still loving every minute behind the wheel so far! I have the Dynamic SD4 Auto and only thing I have noticed so far is when waiting at lights while the car is idling the engine will sputter (if thats the correct term) - revs will drop slightly then pick up a gain ( the car will move slightly as the idle returns to normal ). I initially thought it was going to stall but timed it and it does this every 8 seconds or so, and have only noticed this when waiting at lights (foot on brake when in drive). It's nothing serious but have not noticed this in an automatic before and wasn't sure if it was common or not.

The car doesn't do this when in park - idle is fine.

It sounds like your gearbox is "catching" to quickly at low revs. I would watch it for a few more day if its not bothering you to much. The car migth just settle in a bit more. If not have it adjusted at the dealer.

RE: Engine sputtering at idle

I can confirm I have the same issue on an SD4 auto at idle in drive. The engine revs drop intermittently with a knocking type noise. Not observed this on the Wife's SD4 Auto Freeloader.

I will experiment with high electrical loads an air on on or off to see if that impacts the issue. It idles fine on cold start up in drive and when warm in neutral.

Mine is booked into Guava next week for mud flap fitting and to have this checked out.

I am thinking air mass flow sensor, ECU remap type fix. I will publish the diagnosis and fix when mine is sorted.

It is not a major issue, but noticeable and irritating on what is a fantastic vehicle.

RE: Engine sputtering at idle

Interesting - mine is still doing it, and I have played around by turning air off and all electrical and it still does it. The main problem is seems random and I cannot repeat the problem under any conditions. I have mine booked in for next Tuesday.

For me it's not an agressive knocking noise but just a quick shake to the vehicle as the revs drop and comes back in (feels like its about to stall). Starting on cold it's fine, and when pulling away after an incident has occurred is fine as well.

Did the dealer fix your issue? If so what was the problem and solution?

I managed to demonstrate the issue to the technician, but he did no recognise what it might be immediately. He suspects DPF, I am not so sure as I drive the car over 40mph every day for at least 30 Minutes and it has only done 444 miles.

Guava will run diagnostics on it today, I will let you know the results.

RE: Engine sputtering at idle

it won't be this... but these symptoms (spluttering and recovering with no seeemingly ill effects on normal running) can sometimes be attributed to low oil pressure.... check your oil level.

Ordered: Fuji Dynamic Lux Coupe / style 7 wheels / Privacy glass / adaptive xenons / something else which I've forgotton.
Should be end of April (was March, then April, then end of May/June).

RE: Engine sputtering at idle

We had to cancel our original appointment due to other commitments so I will have to monitor and reschedule. Not sure if it's me being to fussy and perhaps this is normal.

What you have descibed is not normal, our Freelander SD4 (identical engine 190 bhp and drive train) is very steady at idle and has not shown any issues whatsoever in one years ownership.

Racing snake, I was not expecting to check the oil at 444miles, however I know my wifes SD4 consumes it and needs a top up between services so will keep an eye on it. Hopefully the dealer will check this today.....
