Sorry for confusion.... Pin 1 connected to pin 2 has 0.1V
Only pin 1 connected to lin 4
And pin 2 connected to pin 4 has power

 

Measure pin 1 to a body earth see if there’s 12v, you will probably need ignition on.

Measure pin 2 to a body earth using resistance, you want to see 0 ohms

 

Johny you are Godsent...i will check tomorrow.......will report back with finding...

I honestly appreciate your time and skill to explain to me the things i have to carry.
Have a good night.

 

Looks like the ground is missing from pin 2.

 

Chris is you have any tips please thorw it at me... Goong to work but will work on this puzzle in afternoon. I understand a little of te diagram...but dont understand it all.
Thank you

 

As been said from the beginning you need to check continuity of the wiring.

The ground is obviously missing so the actuator is not powering up thus the code 00449A no position signal back to the DDE. In the DDE/ecu box check the connector X6011 pin 7 should be zero volts

 

Forgive me....but i literally bought multimeter yesterday...

I will run pin 1 and oin 2 against chasis as adviced and then check the resistance ..

With humble respect i would say with a little of more guide i can tackle any task.... Can you tell me...checking you mean the pin with ground/chasis if there is a power?

 

And if you can....if the ground is missing ut means that the cable is broken somewhere or disconnected?

 

Pin 2 on the actuator is permanent ground(0 volts) from this pin the wire goes to connector X6011 pin 7 in the ecu box and then continues to chassis ground. Measure voltage at X6011 pin 7 should be zero. Check this connector for good connections.

Report back the voltage. Black probe on metal part of car body/engine, red probe on the connector

Yes looks like pin 2 of actuator is floating and not grounded/disconnected.

Try that first

 

Yeh...will do....will be afternoon before i get to it
... Ecu is sealed under couple screws....locating the connectorx6011 will be fun...is it looks like ramen soup inside the box... But i am confident that i can check that... Thanks a lot

 

You might find the turbo may wakeup when you move the wires.

 

Pin 1 is 12.5
Pin 2 is 12.5
Both against chasis....

 

Code is gone...gonna test actuator.... Some muppet obviously bended it inside and so bad that it was touching pins between

 

Working?

 

Sorry was running ista+ and testing it... hallelujah.... Actuator working like a charm...and helll...i forgot how the car felt... Finally...


And i found how it happen..a guy fixing the real issue with actuator uplugged the plug and managed to bend the pins...why or how i dont know... But having said that i had actuator issue...innitially as the vanes were stuck and the arm coudlnt move ...


Would you mind and send me your revolut or paypal i own you abd Johny bier or two.... Please dont let me beg yous

 

**** sake what kind of clown manages that, shame you didn’t check the wiring before changing turbo and actuator.
at least it’s sorted now

 

Chris and John

Actuator was damaged...the vanes were stuck...so whats the chance that both were fucked...

I dont wanna sound silly but i feel now like main bmw specialist... After going through hell
.. please send me revolut or paypal....jokes aside...i will sent you a bier or two.

 

So for weeks of no sleeping and searching endless answers or possible solution from french forum to polish, Spanish i found a 2 souls that went beyond and yes saved me car and not only that...restored my sleep patern...i was absolutely desperate and depressed...but in process i learned tons of new info that i will pass myself further...

The problem may sound simple but the diagnosis wasnt...

From the bottom of my heart i thank you Chris and John for spending your time and sharing your valuable knowledge with some stranger that few days a go you didnt even know. Yous dont even know what you have done...

May God Bless you

 

Glad you have eventually got it fixed it must have been driving you nuts. I enjoy trying to help where I can it gives me something to do as don't get out much and I enjoy the learning and find it interesting. Pass the love on and help someone else in need.
