And Again no power... headbreaking

came back from france. 1100 km with close to zero power in the Discovery td5 2002.

Back home by passed the turbo regulator by put a vacuüm hose from the intercooler inlet direct to the waiste gate.

Removed the ERG and blinded the exhaust side.

Test ride and was more than happy.. first time i reached the 160 km/h on the Clock.

This morning started the car and no power after to get the rpm up. Feels like i have to push it from the 1700 till 3000 rpm zone. After the 3000 Rpm feels power comes back.

Checked all on air leaks and checked all wires...

Just headbreaking now...... any ideas.

Changed mas sensor and no change. Clean the map sensor in the air inlet.
Waste gate is moving

Strange is when i disconect the mas sensor, the turbo pressure sensor in the engine inlet, the sensor in the air filter and start.. engine stil start and give no error. Result with all sensors disconected is the same as all Connected.

What does ye diagnostics pooter tell ya?

Live data is best way.

Bought a Nanocom and got it today. All ECU input like AAP, MAP, MAF seems ok and see no strange values. Lack of power and tubo turns up from 2000 tot 3000 rpm really slow. From 2000 to 3000 rpm takes about a minute. Just at 3000+ rpm is see normal turbo pressure.

No oil in the injector harnass wires. To be sure i replaced it. Changed the full filter.

Next is to change the fuelpump. Got this in tomorrow.

Finally power back again. At the end it was the MAP sensor. Cleaned it twice and the nanocom was reading a pressure, just not the pressure what was needed.

Thanks for reporting back what the issue was.

Phew, that's a relief

Glad you got it sorted.

How did you trace the fault? I thought Nanocom was not giving any strange MAP values.
