Thanks for feedback. It`s my first video ever. Let me know if you looking to find something specific regarding these cars and engines. Regards

@@wolftech4705 at the moment I’m dealing with the same issue you’ve just covered. I’ll certainly come back here for anything else that crops up with my CLS.

@@escatel6889 if that could help i can make quick video about how i did all that repair on actual actuator

Thanks for the feedback. I hope it is usefull

The answer is no you cannot move the actuator arm with your hands. Reason is gears and sort of gearbox system inside between the motor and arm. Only way to check it as far as i know is with ignition like i did on my video (on/off) or if its completely dead then by diagnostic fault code.

How did you sorted out your turbo actuator?

Can you help pinpoint cause of my excessive white smoke?

Im not pro in video shooting - just tried to help with some info i have. I hope it did work for you

Thanks

It should work straight away even if fault codes have not been cleared. In your case i would say your actuator has not been fixed yet - check for another damage or double check the one soldered - its not easy job for first time

@@wolftech4705 Thanks for the fast reply. I'll take it off again, and bring it to the electrician guy to double-check. At least I know that it should work right away when fixed. Kinda drives me nuts, first the Y air intake pipe (on turbo) broke, after the fix the actuator failed 10-15 day's later... No idea if it has to do with the air intake pipe, or the actuator broke on its own. Btw. the turbo vanes are not blocked, the arm moves freely when disconnected from the actuator.

@@Cetax good luck. Let us know its going for you

@@wolftech4705 update. Gave a visit to the el.guy. He disconected the actuator for a check, and told me its find. After he connected it again and "magic" happend, it worked like a charm. Not sure what went wrong when I connected it(doubt there is a wrong way to do it). But bow it works better than ever. Has full power... 🙋🏻‍♂️

@@Cetax good to hear - enjoy your ride

Not sure what do you mean saying "disabled video"?

Could you clarify which year model is your merc?

@@wolftech4705 its 2004 pre-facelift

@@Ender1337 to identify power loss issues i would go through few steps, starting with easiest one: 1- live data on turbo boost; 2- vacuum line leak or blockage; 3- condition of fuel injectors. Using good diagnostic tool, check is your turbo boost pressure high enough under hard acceleration - if turbo boost pressure is too low: 1- need to identify is there any crack/split in one of the hoses; 2- or turba actuator (wastegate) is damaged; 3- or vacuum lines are leaking or blocked with dust/dirt. Fuel injector checks i would leave as last step since thats most complicated comparing with above mentioned checks Let me know if you need help with any of these steps

@@wolftech4705 So this needs to be test on the road right? Or can you check the turbo pressure while in a garage? And any numbers we should be moving around? How do we know if the pressure is high enough? Thanks so far for the tips, should have it solved in a week or so, will let you know for sure.

@@Ender1337 yes, thats correct - turbo pressure can be tested only during test drive. Normal pressure on mercs must be 2-2.2 bars. Can make short video about this vacuum line can be tested using handheld vacuum pump (about £10-15 on ebay) fuel injector tests - easiest (but not 100% accurate) is leak test - such kit also cost less than £20 on ebay. Im using manual pressure pump and electronic pulse adapter to check how good injectors are holding pressure and spray pattern

Im afraid there is no help to your issue at the moment. As i mentioned in video you can not directly replace your turbo actuator with another one because it needs to coded to car. Thats why i repaired my one

@@wolftech4705 oh ok thats really bad. I asked mercedes they said the turbo actuator learns itself. Thats why i changed mine

@@ossi8221 if you watched my video then i did mention this issue regarding mercedes dealers. If these units would learn themself then noone wouldnt have such trouble with them

Hi have you fixed the problem? thanks

@@marti4580 yes. It was the turbo geometry that was Stuck. I bought an original refurbished turbo from the Internet. IT came perfect. I swaped the turbo and Now the car works perfectly

Not as far as i know. But who knows...

@@wolftech4705 I have changed it today, doesn't need to calibrate. I got a problem p2359 low boost. Fixt intake hose to turbo, new turbo, new ic hose check for leaking. Everything is ok, I have lack of boost en cant find gen problem, do you know what i am missing?

@@MrFietslicht i have never seen option to calibrate these - thats why everyone is struggling with these turbo actuators. I have tried to replace with some another units but no luck to get these to work - that is why i had to repair my old unit. Regarding your lack of boost pressure - your engine must go into "limp mode" - as soon as it goes in limp mode there must be new fault codes. So the best you can do is to clear all old codes - restart car - take it for short test run - scan for new codes and share them

@@wolftech4705 the code is p2359 low boost. Everytime I drive a little the code comes back. I changed almost everything. But code stil comes back. Today im gonna try to clean egr. Maby that helps

@@MrFietslicht Did you checked your old turbo actuator for internal damage like in my video??

Sorry - no idea what you are saying
