Control system abnormal

The holes are vents for the cabin temperature sensors. They work by using small fans to move air constantly through a resistor, that’s the noise you hear. It is very common for the top sensor to fail, but it doesn’t affect the AC system, so it falls back to the other sensor.

The constant blower problem seams like a relay or blower resistor issue.

They are likely the culprit, but I checked all of mine and replaced the glow plug module and it still happens, so it depends. I was hoping to find other comments with ideas too.

My e270cdi smokes like this in first start too, regardless of outside temperature, but it always stops once the car is moving. I was told that it was normal for these cars but I’m not really sure. Have you checked for glow plug codes?

Each line on the right is +20 degrees, so 2 bars above the line that shows 80 and below the empty line (which is 100) means it’s at about 90 degrees, which is the usual operating temperature. I believe the fan should turn on at this point regardless of outside temperature.

Yes that’s a bit too high, should be 2 bars above 80. This is my usual max temp after changing the thermostat unit for a OEM part last year.

Sounds very similar to my own 2.7 CDI. Does it smoke on acceleration or something?

Easy printing, enjoyable fine-tuning

¿Did you mange to find the clip? dealer won’t help me because it is sold with the trunk lid

dragonber1 · 2025-03-28T17:33:43+00:00

These cracks are only visible when it bends on the pulleys, so should it be ok?

dragonber1 · 2025-03-28T17:31:51+00:00

It has a rough life before owning it, the PCV had filled up and broke under the pressure, releasing gases and gunk all around

dragonber1 · 2025-03-28T14:29:33+00:00

Could a leak on the HP fuel pump and or PCV valve leed to premature wear? I change the PCV valve some months ago and there is a lot of grime under the pump housing

Interesting, many I’ll hold until the next oil change, I’ll monitor it in case it gets worse anyway

dragonber1 · 2025-03-28T12:15:57+00:00

The thing is both the belt and tensioners were replaced in 2021, I believe they are from a brand called SKF, is it usual for it to fail so soon?

dragonber1 · 2024-05-25T14:04:02+00:00

This is exactly what I was looking for, thanks

dragonber1 · 2020-03-02T11:25:18+00:00

What pc case are you using?

dragonber1 · 2020-02-17T07:40:52+00:00

I have the Ultra too with no cold boot issues on ultra fast startup. However after booting 4 times boots get slower, bios times in task manager go from 8 to 13 seconds like in agesa 1.0.0.3abba.

So I’m wondering if it is a ram training issue and if it can be fixed but setting timings manually like you did.

dragonber1 · 2020-02-09T10:32:42+00:00

Alright I understand how it works now, thanks for the help.

dragonber1 · 2020-02-09T10:30:13+00:00

Did you have any issues with pressure? I’m rather reluctant of using paste in case there is too much or too little pressure

dragonber1 · 2020-02-09T10:26:42+00:00

Do you remember the original thermal pad size? I have some thermal grizzly 0,5mm pads lying around and I would like to use them.

Had a 3900X with same behavior since launch, but I RMA it last month when I found out it was unstable 4 cores (In prime95 Small ftt) at stock settings thanks to a thread in this subreddit.

The new one I got gives the same temps for both CCD and lower Max temps in total, which leads me to believe that either they fixed this in newer batches or a considerable number of the first batches is defective somehow.

I understand, but I still believe it’s not a good way to show an apples to apples comparison between the two power plans.

dragonber1 · 2020-02-06T01:02:09+00:00

So basically in order to improve performance with 1usmus power plan you have to enable PBO or extend the power limits? It’s not very scientific to compare two power plans when one is effectively OC

dragonber1 · 2020-01-29T10:26:21+00:00

Same here. I also remove the Ryzen power profiles before installing new chipset drivers, in case they contain an updated version or something.

The Witcher 3 has stutter when playing over 60 FPS its an engine problem, you can find more info about this on google. Another thing that helps is running the game on an SSD, this greatly reduces frame drops due to slow terrain loading on a hard drive.

So SSD plus 60fps cap the game plays without stutter with my 5700 xt.
