Hi andrewwynn,

As far as i remember i do , but i will have to test again tomorrow just to make sure that i have power on front axle. The only thing i feel sometimes like a little "scratching sound" below the car mostly on hard acceleration

The only fix that i did on transfer case was the fluid change and adaption that has been done a while ago when i bought the car from Switzerland.

I don't know if a failing transfer case actuator will trigger that error code..

1. I have replaced this part: EGR boost control (https://www.ebay.co.uk/itm/For-BMW-X...-/352237914090)

2. I only turned off the DPF from the car and not the EGR !!! The EGR was cleaned just to make sure there was no dirt in it.

3. YES, my e53 has electric controlled turbo that is not vacum controller like earlier models.

---------

Soooooo finally i took the car again to the turbocharger repair shop and they have replaced the actuator module. it was a known issue for them when i explained again the problem that i had with the the car that it would work fine when starting or when it was cold .... but after a while you would feel low boost etc or poor acceleration after 2nd gear..

AND FINALLY my issue is solved for now with no Smooth Running errors , if they appear again well ... it will be time to check other things . (i hope not )

That's a Chinese copy of the original Hella actuator but great if it works. If your problem was heat related it sounds like typical failed wiring inside actuator from board to motor supply. I had the same on mine a few years ago.

yes that is the module that they replaced. I had a look on the old module but there was no disconnected wire like yours in photo.

They told me this fail often and that not everyone is able to notice the powerloss.
In my case the car had to be warmed up to feel the power loss, and if you would restart the car it would work for another good 30 min or so then again i would feel the power loss .

I must say this issue drove me crazy

But the strange thing is that it was triggering different error codes on the diagnostic device , example: (DDE: Charge-Air Pressure Sensor) . This specific error told me the turbo was not working properly so that’s why i sent my car to them to have a look since they partiay rebuilt that turbo feee weeks ago

Edit : i didn’t asked them if they replaced it with an oem used or a replica of this module. Im glad it works tho

Nothing wrong with your English, raydhimitri - the confusion comes from the vague eBay description - the same pressure converter unit is used for either the turbo boost control or the EGR control - they are interchangeable and the eBay part can be used in either role.

Knowing (now) that you car came from Switzerland also helps - it explains the EU4 spec.

The item name was really confusing me aswell becouse on realoem.com it was named differently
I bought the part here in my country not from ebay becouse i couldn't wait for it to arrive , it is an italian production but works really fine and no issues so far.

The only downside of my e53 is that it doesn't have a panoramic sunroof but that's not a problem for me.

It's also strange becouse all of e53 that i have seen in my country (Albania) from 2004 to 2006 are equipped with electric turbo and DPF. Normally everyone disables the DPF here becouse of bad diesel quality.
My old car was a 2001 e53 3.0d with vacum controlled turbocharger (never had issues with turbo on that model)

andrewwynn they seem to spin just fine, the only thing is the feeling below the car on hard acceleration (happens only sometimes on highways).
Im not sure it's worth it to open the transfer case actuator , any suggestions ?

Searching for the code you listed (5F5B) comes up as a number of variations: -

- CAN Message/Instrument cluster- Error: Instr2, ID 0x613: Km_Stand Sending Failure Identification

- DSC -5F5B DSC Instrument cluster

Seems related to DSC (ABS) rather than VTG (transfer case)?

Wouldn't a bad ABS module trigger the 4x4 light on the dash?
Based on this thread https://www.drive2.ru/l/479136382132944962/ this guy seems to repair the transfer case actuator and no issues or error codes after that.

You can disable the front axle with a fuse. Try reproducing the problem with only rear axle.

Usually TC problems will present at low speed high torque I don't think you are looking at TC issues. Look into the CSB center support bearing.

The feeling (becouse there is no noise) below the car accompanied with a little bit of vibration happens on hard acceleration and it is even more noticeable when the steering is moving .

Is there any thread for the fuse test ?

When i purchased this car it has a hard clicking noise from below and sound , i replaced only the Transfer Case oil with an oem one and issue was resolved..
