Freelander 2.0di. Help please!

Hello All,

You have probably seen a few of my posts about this but here goes again as its still a problem.

I have had my Hippo for about 6-7 weeks now and it has been fine until last week when it started to judder and lose power. It also started to throttle up on it's own...

I sent it to my local independent LR specialist and he plugged his diag machine in and it came up with throttle positioning sensor fault. I had this replaced at a cost of 235.00 pounds and its still the same! He then cleaned all of the connections to the ECU and various other sensors oround the engine and bought it back saying it was fixed this time. Well..... it wasnt.

I took it straight back to him and saw with my own eyes what was happening. The TPS would not come back down to 0.00% on the diag machine. We would reset it to 0.00%, throttle up and it would settle back down and then slowly climb on its own back up to 30-40% of the throttle movement (if that makes sense) sit there for a few seconds then settle back down to a high idle. I am stumped now!

Someone else mentioned the crankshaft position sensor could, when dirty offer false readings to the ECU causing this problem. Does anyone else agree with this?

Help needed as the bill is climbing!

Many thanks

Luke

Sadly it may be a case of you having to keep changing the parts until the problem is sorted. There may be a valid reason why the TPS shows throttle advance without touching the pedal. The programming of the ECU is completely unknown to us. Emission control can cause the throttle position to be modified for example. Good luck.

Thanks Darmain. Could the crankshaft sensor cause the engine to do this? I am just thinking if it is dirty it could be sending wrong signals about crankshaft speed to the ecu?

Thanks

Good next step I would say.

Right, well it's back and this time it is fixed.

Apparently, and I am not sure I agree but a sensor plug and a broken wire was the problem. He also changed the TPS and still says it was also at fault.

I feel like he has taken advantage of my lack of knowledge in this area really as I find it very hard to believe that all three things failed at pretty much the same time..... but how can I prove it I suppose.

Anyway, if anyone else has this problem you know what to check first and avoid a 650.00 pounds bill!

I suspect he couldn't prove what was the problem either. Look at it this way, you've got a new TPS so that shouldn't give you trouble again and you've got a happy Hippo to go out and have some fun in. I'm glad you are sorted now. The expense is an annoyance that is along for the ride with these cars.

Happy Freelandering,

Dave

That is very true. Glad to have it back, and working this time!

I'm very wary of dealers working on my vehicles, that's why I do my own work whenever possible. Unfortunately, even myself using the full diagnostics doesn't mean I can fix the faults as if the computer is saying there's nothing wrong when obviously there is, it can be a trial and error route to find the problem, normally by fitting components untill the fault is cured. If a dealer fits a part and doesn't cure the fault but charges you for it, then it's down to you to argue he has fitted parts you don't need and shouldn't be charged for if they put the old item back? I know I can't return electrical items once purchased from the dealer, but would guess this is different if the dealers own technicians fitted them?
