| Rough Engine & Power Loss |
|
I recently purchased an ex demo TDV6 SE Auto and so far very impressed - that was until toady  What was a beautiful, smooth engine has turned into a rough sounding engine that has to be worked hard to obtain the same power that I was previously getting easily. Fuel economy is also poor at around 19 mpg around town. Car has done about 9000 miles. No warnings are coming up on the message centre. Has anyone else experienced this problem with the TDV6?

Sounds obvious but have you checked the oil? The engine seems to have a thirst for it and when mine had a low level it made the engine run rough. (no warning came on despite low oil) 2020 BMW X1 18d XDrive X-Line Auto

Andy, thanks for your fast reply. Checked the oil, which was very low and is now topped up - hope this hasn't caused any engine damage  Very slight improvement in noise, but still feels sluggish and 'tappety' when compared to how smooth and quiet it was before.

if you have run low on oil it will do damage the oil light will only tell of low pressure you can still damage turbo,crank, shells etc without the light coming on

It sounds to me like your turbo pipe has come loose. Exactly the same thing hapened to me on a brand new Range Rover TD6 a couple of years ago. The car suddenly turned into a Massey Ferguson (slow, noisey, black smoke, bag of spanners) and I really thought I had blown the engine. Turned out to be a loose clip that atached the turbo pipe. Pushed it back on and she immediately reverted to normal. Mind you, even as normal, compared to a TDv6, the TD6 was (and is) a bag of spanners  Disco 4 TDV6HSE

If the oil pressure light has not come on, the engine has not been starved of oil and the oil level, whilst low, can't have been below the level from which the oil pump takes its feed. I would suspect something else.

sorry but that is not the case an engine can still be damaged by running low on oil even if the light does not come on the dipstick can be dry and the oil light will not come on but see how far you get driving at 70 mph have seen many machines with main bearings spun out, turbo bearings shot, etcjust becouse it has oil pressure at that particular spot on the engine where the sensor is located dont mean all is ok if a problem did arise and the engine dismantled it will be clear to see if it has had oil starvation its why it says danger low on the dipstick.....

Macker, where did you get the D3 from?? I'm guessing Town and County, but wherever it was, I suggest you get back in there...... smartish

I actually bought the car from Stratstone (Heathwood Land Rover) in London. This is the 3rd Land Rover that I haven't bought from Town & County, due them not being able to match the deals others offer. The car was delivered to me and I assumed (wrongly ) that it would have oil in the engine! I'll book in to T&C tomorrow, but I'm also hearing a wooshing noise at certain revs, which may point to the intercooler or turbo??
Don't get me wrong, the car doesn't sound like a bag of spanners, it's just lost it's smoothness and some power.

Only had the car for about a month. It had done about 8,800 when I took delivery and I've done about 1,000 in it. The problem seems to have started in the last 100 or so. No smoke.

Catoperator,
What you write dosen't make sense. An engine has one oil pump that serves all parts of the engine that require oil eg main bearings, big ends, camshaft, turbo bearings etc. As I said earlier, as long as the oil level doesn't fall below the oil pump feed pipe, oil pressure and delivery will be maintained to all these components. There is a considerable safety margin between the oil low level on the dip stick and the level at which the oil pump sucks air. This is to account for taking corners and orientation of the vehicle.
I still don't think Macker's problem is low oil level if the oil pressure warning light didn't come on.

I suspect the problem may be related to an EGR or turbocharger issue.

maybe you need to look inside an engine or two that has been run low on oil where the oil pressuer light has not came on an engine can and will be damaged if run low on oil i have seen and ran engines that sound like a bag of nails oil pressure light not on no oil on dipstick crank and mains etc ruined... that is the reason bulldozers etc are fitted with a scavenge pump etc if not when working on steep angles the momentarily loss of oil to the pump will not make the light come on or gauge drop but will ruin the engine and to quote cotefarmboy ran better after oil was put in  i dont think you should lead people into beleaving that low or no oil on their dipstick is ok they may look prats when they tell the dealer some bloke on the disco3 forum says its ok
