Question Loosing power after being on high load for long 2.0Hdi RHR 2005

So folks I started noticing one issue when I am trashing it a bit uphill, after long drives it looses power, it doesn't go to limp mode (when I put it in neutral and press the gas revs go all the way) it basically stops around 2000RPM and won't go over it like really really slowly no that familiar kick and pull even on flats. As soon as I go down hill a bit and temperature drops power is back.

I would need your opinion and so no error codes so far no beeps. What I did notice is that car will start rising the temperature over 86-87 degrees where it usually stands much faster than before, usually when it was super hot in congested traffic then it would climb over 90 but now it happens often. And I washed the radiator 2 months ago so its not it. And it doesn't go over 93 so its not overheating. Only when it hits 93 temperature I notice a drop in power. that gets worse if the car is under load

The car is 100 stock so DPF is working and EGR is not blocked.

I started linking some dots that might not be related so bear with me. I have that soft travel brake pedal issue, and also once my brakes when almost dead when I trashed it hot. It never happened again. And could it be that there might be vacuum issue with the air circulation regulation system so when it is ultra hot car will get low on power because its not getting the correct amount of air and I am linking this to the vacuum pump. Since there are no errors and usually there is no errors with the vacuum. And I found few people online that fixed long traveling brake pedal with replacing the vacuum pump. I was wondering since I have few issues that can be linked to the vacuum.
Do you folks maybe have any other ideas? What else might it be?
Do you have any ways to test vacuum pump?
Can Clogged DPF maybe cause this? (but it doesn't matter how long after regen I trash it will again lose power)


Thank you folks

Hi,

Just a thought, is the temperature gauge really giving the right value? If you use diagnostics does it match what is displayed on the dash?

There are overheat protection maps in the ECU which will cut torque when you're hot, but you need to be really hot for this, which makes me think maybe the gauge isn't showing the full picture.

Temp limits can be:
Fuel
Intake air at MAF
Oil
Air at intake manifold

Interesting, yeah it really does look like its downgrading the power, hm this is cool I will test it i have that cheap OBD reader can display temperature (so I will check that) But shouldnt it push stop sign on the dash and put some sort of overheating warning if it overheats that badly no matter if the gauge is wrong?

Hm new simptom, so I was blasting it on the highway and it was going like a charm like really blasting it, and than after maybe 20km it just started losing power so even downshifting wouldn't make it climb revs. But still, if I would put it in neutral revs would climb all the way up. When there was little downhill it seems like it has some power to accelerate but then as soon as it is flat or even slightly uphill it won't accelerate at all.

Then I turned the heat all the way up in the cabin and engine temperature dropped significantly (almost below 80) engine still wouldn't accelerate. After a few kilometars (of easy driving) I turned off the engine and started it back up and most of the power was back.

Now I have no clue where to look, my friends mentioned MAF might be causing this anyone willing to help in this mystery?


I have changed the original subject "Low on power when temp is over 90C 2.0Hdi RHR 2005"

Disconnect servo hose from vac pump and try a squirt of oil into the vacuum pump and refit servo pipe incase valve in pump is sticking when hot

Well, it lost power over 2000RPM almost completely, so far they diagnosed broken turbo, so the Variable geometry control broke apart so turbo wasn't spinning yikes, will update this for the future
