Defender 2.4TDCI won't rev past 2500 rpm

[stobbie]

We have a 2007 Defender 2.4TDCI here and it will not rev. 

When it is cold it stops at 3000 rpm, but when you keep the pedal depressed it will go past 3000 with a lot of noise.

When it is warm it won''t go past 2250 rpm.

When you drive it, everything is normal, normal power, it just cuts out at 2250 rpm. Sort of like a limiter, a sort of on-off on-off..

At first it showed an injector fault code, so I have had the injectors tested and they are all fine.

I've done a pump calibration in SDD, and that completed without problems. I've done a pilot learn and that completed without problems as well. No fault codes present anymore.

Rail pressure seems OK in the live data in SDD..

Anyone an idea?

Hello,

I need to go through a few  steps with you please:

1) Can you see the clutch switch in live data ?

2) If you can see the switch does the torque request change when you depress the clutch pedal

3) Do you see a 100 percent pedal travel when you do a sweep of the pedal switch ?

4) What is your battery voltage before stating and does it change when the concern occurs ?

5) What is the fuel rail pressure in live data when the condition occurs ?

6) Has this vehicle ever been tuned ?

Let me know what you find.

Regards

Phantom

Hi PhantomSVE,

 

Thanks for your reply. Unfortunately our customer didn't want to wait anymore and has collected the car without having it repaired. I'll try to get him to come again and I'll do the tests you've mentioned..

that looks fairly similar to what was happening to a van i had with a faulty MAF, unplugging the MAF let it rev.....
