2010 Defender 110 Puma 2.4 USW Stornoway Grey

Brand new 110 XS Puma losses power

I have a brand new 110XS Utlity with 200 miles on the clock.
All was well but taking it on an A road for the first time I have the following issue.
I drive normally for a half an hour on B roads with no problems.
I started down the A road and get into a cruise of around 50 mph.
After about 15 minutes the problem starts.
A sudden loss of all power, pressing the accelerator has no effect on revs or power.
The engine is still happily turning over with no coughs and there is no red lights or warnings.
AFTER the loss of power the engine temperature rises sharply and within a few seconds it is approaching max.
The temperature stays high for 30 seconds or so then comes down again rapidly and in a matter of seconds from starting to come down is back to normal.
It makes me think that the engine temperature can not really be changing that rapidly.
AFTER it reaches back to normal temperature the power will come back again, I then can drive normally for a minute or so and the problem comes back again. I get back on a B road and the problem disapeared.
I took the car back to the dealer and they checked for any fault codes but there were none.
The cars going back to the dealer for a proper investigation but does anyone have any insight into what the problem might be.

Mass air flow meter? Its on to of the air box.

Mass Air Flow (MAF) Sensor: This sensor measures the amount of air coming into the engine. Less air is drawn into the engine when it's idling, so less fuel is needed. More air is drawn into the engine once the car's in motion, so more fuel is needed from the injectors.

The sensor is a small unit with two exposed wires; the wires heat up when the car is running, and the MAF measures the airflow by detecting how quickly the flow of air cools the temperature of the wires

This is a fault i think i may have heard of before - althought the alleged solution was to clean the mud that had been trapped in the radiator...clearly if yours is new this isnt the case.

However, it always seemed an odd issue for me (to blame mud on stopping a defender) Mike

Thanks Guys

I found a thread on another forum with google.
Landy Man has posted the exactly same problem I have.
http://www.4x4community.co.za/forum/showthread.php?t=23178
Thankfully towards the end of the thread which goes off course a bit he posted his solution

"About the original power loss problem: LR did an ECU update on the truck, which seems to have resolved the issue "

Which ties in with what you say Rob.
I'm going to suggest this to the dealer.

BTW
I had to wait 4 months to get this Landy from the factory but I still wish I had my TD5 back which I had 10 years of faultless use , well apart from stuff like it leaked, you couldn't shut the drivers door when it got hot on a long run, stuff like that which became part of its character after a while. But it never let me down and the only reason I have this new one was my TD5 was stolen off my own drive. I expect I will get used to the Puma but it doesn't sound like a Defender to me, and that's when the engine is working properly. Too quiet.

I think you should let them know your not happy and are prepared to regett the landy. I am sure they will sort the fault. My local dealer said mine wasnt due for software update. Then a day later they call me and say its all fixed rob we have updated the software. Everything about the drive of the landy changed for the better. Now I am very happy with.

What are the criteria for rejecting a new car ?

2009 Defender 110 Puma 2.4 XS CSW Zambezi Silver

I have just had mine fixed (hopefully) after a year long battle with 5 trips to the dealer I bought it from and after giving up on them and taking it to another one.
Basically they kept saying it was a fuel pressure problem, however after 2 weeks at the new dealer they discovered a crack in one of the turbo pipes.

Ok, that's interesting. Could you confirm that you had exactly the same symptoms, that is after the loss of power the engine temp shot up, then after the temp drops to normal the power comes back, then the cycle repeats it self.

I never had any temperature problems, just extreme loss of power which seemed ok when you restarted the engine.

Power loss

My 07 puma has the same problem usual between 2nd And 3rd gear changes. No power like extreme limp mode. Letting it idle and coast along for 5 seconds or so can fix it. Anyone got a solution or more importantly a reason!!

Update on my power loss problem.
Dealer was told by Landrover to investigate cooling system as a prime suspect. The dealer first changed the 'engine temperature sensor', during the road test, the power loss happened again. I was relieved that at least they had the same fault so they new it really happened. They then changed the thermostat, this I'm pleased to say solved it. I can say for sure as I've driven the car to Italy and back with out any problems at all. I'm beginning to to really like the Puma now, re-building some trust in it. My only complaint on the trip was looking at the trip odometer on getting home, I had only done 320 miles! Studid thing only has 3 digits, I had to work out how many times it had gone round the clock. Straight out the Ford parts bin no doubt.
Portafilter, I would take a close look at your engine temperature when you lose power, mine went up and down like a yoyo then the power came back on.

Rob,

I hope you getted it sorted.

on another note I hope this doesn't mean I've got another 80 miles before the problems start?
