My Berlingo 1.9D started to be extremely hard to start. Also during driving the engine check light comes on intermittently...especially when I release the throttle downhill.
After start it runs fine without any problem, maybe just a bit more smoke and the annoying check light and beep sound during every 2-5 minutes.
During a diagnostics it came up with two fault codes:
P0170 and P1146. P1146 is saying that the needle lift sensor signal is not readable. The other fault code is related to problem with timing..I believe this is due to the faulty needle lift sensor signal...
Today I fitted a used injector with needle lift sensor which came from a car that had run 23 k. This did not help... When I check the resistance of the sensor is says 103 ohm. Does anybody know if this is the correct value?

Re: Engine check light due to needle lift sensor
my 1,9 td xantia used to put the light on and it came up with lift needle codes, what it ended up being was the strainer in the tank, the strainer in the tank had what looked like dreadlocks hanging off it ( almost looked like fat from what you get in the bottom of an old frier), turned out that was stopping diesel getting sucked up and efectifally starving the engine of diesel, so might be worth checking the strainer ( bottom of the fuel level sender as its an all in one unit) and your fuel filter

Check the picture in the 4th post down. This occurs with diesel tanks;

Re: Engine check light due to needle lift sensor
This can actually be the problem since the car usually starts immediately if I use the prime pump before starting. I have replaced the fuel filter, but have not looked at the strainer. How do I access this on my berlingo? Under the car or inside the car?

Re: Engine check light due to needle lift sensor
tbh im not sure on a berlingo but on a xantia and other cirtoens of the age there was a big black plastic/metal ( if its metal it will be held down with a few screws) cover under the carpet under back seats or in the boot depending on modal,
you'll recognise it as soon as you see it its about 3-4 inch circle , it leads directly onto top of tank and sender unit, big set of grips or something is needed to turn the collar on the tank, (hammer and screwdriver not advised as it just breaks the lugs),
after diesel pipes disconnected ( be carefll as the sender unit connectors aren't the best and they do break) and cables out of way, ( tie something around them so you don't lose them) the sender unit just pulls out,
in typical Haynes style refitting is exact reversal except you have to prime the system using your little bulb thing unless you have an electric pump then it does it for you after 5-6 times of flicking ignition on/off

If we ignore the light and codes, just for a moment, and look at the symptoms as you've described them, this sound's like air entering the system.
This used to be very common with mushroom style primers, built into the filter head. The seal went brittle over time. They'd be perfect until the filter was changed, or you ran out of fuel, and had to use the primer. Then they'd leak air in whenever stationary and the engine would not start from cold without being manually primed. When they got really bad, they could cause missing that got worse under load and horrid white/grey smoke that burns the eyes.
While I don't think this style of primer was used on the Berlingo, the same effect can be caused by perished hoses, or a filter not sealed correctly.
Is there a transparent section of fuel line between the filter and the injector pump? If not, could you temporarily fit one?
You'll be able to see bubbles here, if this is your trouble!

Re: Engine check light due to needle lift sensor
Yesterday I tried to access the diesel tank strainer without any luck. My Berlingo is a 2 seated VAN type. When a removed the big rubber mat from the storage room in the back there was unfortunately only a complete welded sheet steel floor underneath . No holes or any indication of inspection covers here. So I guess I have to take the rather big job to remove the diesel tank under the car to find the diesel level sensor/strainer...
Does anybody have a Haynes manual who explain this?

Re: Engine check light due to needle lift sensor
This problem is still not solved. The current status is as follows:
- I have replaced glow plugs
- I have replaced fuel filter two times
- I have replaced fuel filter housing and primer pump
- I have removed diesel tank and checked the strainer – looks good and clean.
- I have replaced the injector with the needle lift sensor
Still the engine check light comes on intermittently with a “beep”...especially when I release the throttle downhill.
Now I can’t get the car approved in the Periodic vehicle check (EU) due to the engine light and fault codes.
All help and ideas will be appreciated!

Re: Engine check light due to needle lift sensor
Two things... Have you rechecked to ensure the replacement needle Lift Sensor is in fact good? That you see a resistance of 103 ohms is not a guarantee that it is working despite the mileage of the engine it came from.
Have you re-read fault codes and have you used a proper Citroen Lexia diagnostic device to see live data and prove the Needle Lift Sensor is now good. Until this is done you really are guessing with a fault like this..
Secondly, have you excluded all possibility of air ingress causing this... As Sparksie says above, it does have a likeness to the problems of air ingress. It does not take much and it can be all down to something a simple as perished leakoff pipes..

Re: Engine check light due to needle lift sensor
Can the timing belt cause any of these symptoms? What if it jumped a tooth?
I have not checked this yet...but in my opinion this should not cause the sensor signal to be unreadable??
What do you guys think?
Unfortunately I do not have a Lexia tool, so I have not checked live signals from the replaced sensor.

No, It cannot... That can be ruled out.colabrus wrote:Can the timing belt cause any of these symptoms? What if it jumped a tooth?
If you are in the UK there are many forum members on here that have Lexia machines and will undertake a diagnostic for you...
