No power after 2nd gear (Td5 Defender 110 2006)

Hi,
For the past few months I have a problem with accelerating and its becoming very hard when entering the highway. Mostly after 2nd gear when I push the gas, it takes about 20 seconds to accelerate and settle after 1 min until I reach the 5th gear about 100kmh and still I fill the car has no power like before. Please help!

Fuel pump i think it is dead

Or maybe turbo wastegate controller.

There's no wastegate modulator in the Td5 Defender but it could be a malfunctioning actuator, however this would generally lead to an overboost situation (late wastegate operation due to blocked or punctured air hose, or stuck actuator).

Possible causes:
Fuel sender
Fuel pressure regulator
MAF (air mass flow sensor)
Plugged catalyst (if fitted)

Most probably within the first two. Alas not easy to diagnose fuel supply problems in the Td5 engine as no pressure sensors are fitted.

Would help to have engine ECU fault codes read as well as live fueling parameters looked at.

I know what the fuel pressure regulator is but what is the fuel sender?

Fuel pump inside fuel tank.

First things to check would be fuel & air filter, but assume you done this already.

Fuel pump seems to be working, the fuel pressure regulator looks very dirty could this be a source?

The only way to tell whether the fuel pump is working PROPERLY is to measure output pressure across the entire engine load range, as it can run brilliantly at idle when fuel consumption is low, but starve the engine at higher loads (not enough pressure means not enough volume).

The fuel pressure regulator, aka FPR, is prone to fail at some point. This usually involves some form of fuel leak develops, but not always. Again can only diagnose by measuring FPR output pressure under varying engine load.

Both tend to last about 100 to 130k miles, and generally go one after the other.

In any case before replacing these have your ECU interrogated.

I have only 45,000km should it fail?

I will have the ecu diagnose and will see... BTW is the HawkEye a good tool? I thought of buying one

Personally like Nanocom better. Plus on a Defender Hawkeye has no real benefits over Nanocom as you won't need to read air bags or auto transmission. Actually quite the opposite since Nanocom would allow remapping over email.

ok thanks good to know.

any recommended place I can buy Nanocom
