Freelander 1. 2.00 TD4, 2006. Warning light with exlamation comes back and forth
No codes coming up. Patients symptoms.

1) starts. And occasions then dies out.
2) lack of power sometimes under accelerating
3) bit of a miss fire? Again sometimes.
4) smokes like she was on 200 a day when under pressure, hard acceleration, going up a steep hill.
. Again sometimes.
5) out of gear and floor throttle usually no issues. But occastionslly all the above.

ALL THE "Sometimes" USUALLY HAPPEN AT SAME TIME.

Sometimes getting more regular. Has been going on about 3 weeks.

From research on here and other places I am thinking/hoping fuel filter and low pressure fuel pump at the rear?. Opinions greatly appreciated...

Well new filter is cheap, and fuel pumps don't last forever, so I would say you are on the right tracks.

Freddie17 · Jul 28, 2025

Lack of power and smoke could be a loose/split boost pipe.

Other things to check besides the filter and LP pump are the O rings on the high pressure pump. These wear over time also. Cheap repair kits online.

If you have decent diagnostics you should be able to see the high and low fuel pressures.

With 'no codes', are you sure the diagnostic equipment is correctly connecting to the LR protocol?

There are few devices that read the LR correctly.

Could be turbo. Check all the vaccum hoses, replace the turbo control solenoid. Made mine ALOT better, my symptoms not as severe as yours but I had the black smoke under heavy load, that's gone now.

as above replies ..
+ check that the fuel-rail-sensor plug/socket pins are clean 'n totally free of corrosion ..

a code should def. register if that warning light illuminates .. i would think.

Thanks all. Going to start with Filter and LP Fuel pump. If that doesn't work, I will look at the turbo hoses for leaks, After that a gallon of petrol and a box of swan vesta I think

Thing with code, its never on when I get her home. Light goes out and is intermittent. Proper Diag Kit , that has worked before for my landys. If I could get the light to stay one, but will also check the flows when I am testing again.

A word of warning. Don't be tempted to by those cheap pumps from Ebay, as they're garbage. Only fit genuine or OE pumps and filters.

andyfreelandy · Jul 28, 2025

If the engine light has lit once, there should be a code stored to read. This will direct you better than changing parts randomly.

Although, if you are throwing parts at the problem, rather than finding the error code, if you bung a cheap pump on and the problem persists as-is, you haven't wasted much cash and can put the original back on.

I to, feel sure that if the EML comes on, there will be a code stored telling you why.

freelounger · Jul 28, 2025

If you have black smoke, fuel flow is unlikely to be the problem. You don't have enough air flow for the amount of fuel.

Alex1000 · Jul 31, 2025

The smoke is normally grey or Blue/Grey Couple of times, under very heavy load, it went to black. She also seems to "misfire" if a diesel can do that? Again this is intermittent. On a level road, she can pull and go along nicely. This seems always to be when throttling to overtake or coming to a steep incline.

At start up, she will idle badly until I give her a little throttle, then that clears. Prior would have purred at about 800/900 all day long from a cold start.

Freddie17 · Jul 31, 2025

What are you using to check for codes?
As explained above, there should be some codes stored, as the EML has been on (even if it’s now off again).

Alex1000 · Aug 4, 2025

Used different code readers inc a Professional one . Got a few weird ones. One saying low voltage which isn't correct as testing battery and voltage when charging in car, are perfect 12.5 v sitting and 14.34 when running. So that's not correct. Other saying no Signal from ABS, which aagin not correct, as when I ran test cycle on the ABS it came up okay.

Cleared all codes and tried again. Quick run up the road, making smoke signals as I went.

Now I get these on the scanner. But once I turn on and off, and try again, they are gone.

Cylinder Balance Control (0x1613)
Fuel Rail Pressure Plausibility (0x1190)

So of to the internet......

The voltage and ABS are likely old stored codes.
1190 points to your likely issue - checked the fuel rail sensor?

Alex1000 · Aug 4, 2025

Going to. Have advantage I have 'Jlo' (the current Freelander and daily) , and the 'old girl' which i lost keys to and still have to change the locks and ECU etc. I can rob sensors of her, to try switching out until I get the correct one.

pwood999 · Aug 4, 2025

I had the "1190 fuel rail plausibility" on my son's 2004 TD4 recently. Turned out to be the new fuel rail pressure sensor we fitted had failed. Car would go into limp mode every time we accelerated hard or uphill. Put the original back on, and all sorted.

Diags on live data should show Low & High fuel pressures for an indication.

We only changed it because we though the orig was faulty, but that turned out to be regulator seals.

Alex1000 · Aug 4, 2025

What should the high and Low Fuel pressures read? If I can figure out the menus on this damn code reader program. Took half an hour just to find the scan engine codes part. Had me turning lights on and off, rear window up and down, and dont ask what it did to the flashers....

Freddie17 · Aug 4, 2025

IIRC, LP should be around 370/380
HP around 28000

Don’t ask me what the units are - I forget, though KpA rings a bell !

Edit - others that know exactly will be along shortly…
