Mercedes ML320 CDI turbo actuator faults... Fault finding and repair.

[@JamesAllen300]

I've worked on the OM642 engines a lot over the years and one of the biggest items forgotten about is the PCV valve on the back left hand side of the engine. The diaphram ruptures and allows the oil to work its way towards the "Y" pipe. This in turn makes people think that the turbo seals have gone and replace that when it's afaulty PCV all the time. be careful with those orange seals as they are a one time use only. they might look like they are ok, but can not seal properly.

[@LMAutoRepairs]

👍👍👍

[@timmehlittleloud2251]

I was just going to say the same thing. Those rubber seals are a joke. I have a CLK with that engine. The first thing I did with it when I got it was strip it and change the oil cooler seals etc. etc. and the valve at the back of the left hand CAM. If Mercedes just put a bit more thought in their design they could make an engine that was really hard to keep running 😋 I suppose they must think the same what with their new Renault engined beauties.

[@rafiekahmed8568]

When they fail,the turbo acts like a turbo charged vacuum cleaner and such lots of oil into the turbo

[@EndritVj]

On point. Question, is the diaphragm sold separately or the complete unit should be replaced?

[@LMAutoRepairs]

Usually you can get just the diaphragm... 👍👍👍

​@@LMAutoRepairs come and help me fix my ml320cdi im so confused

[@stewatparkpark2933]

Those fine wires are fusible links designed to burn out if the actuator is overloaded so that the actuator motor etc. doesn't burn out . The reason the actuator becomes overloaded is that the variable vanes in the turbo that the actuator is moving become gunked up with exhaust soot . It is very likely that the turbo needs to be removed and the variable vanes cleaned out . Hold a magnet next to those clips when removing them .

[@ikocheratcr]

I do not think so... The ST motor controller has current limit protection, so the only way those links will blow, is if there is major short in the module itself. Also those Al wire are very thick and can handle high current. There is a fuse the powers this module, along with other modules in the engine.

[@atonkin8277]

Is that fact, or possible misinformation (I don't know if it is or isn't) in another, I think Australian, video floating around KZbin?

[@wolftech4705]

nice video - just couple things to mention... 1- code scan needs to be done before you disconnect anything to be sure there is no other faulty parts. 2- most probably part on seat was old part already removed from car - normally you cant replace actuator just like that. 3- dust in actuator actually is from grinding internal gears since unit itself is sealed

[@rafiekahmed8568]

Hi Luis great work from you I see you went the extra mile to make sure that there will be no comeback. Regarding the question if these actuators need programming or not, in this current week I had a similar job it was on a Mercedes’ sprinter with om 642 engine ,the turbo actuator melted because there no heat shield on the turbo.The customer supplied a used actuator and I noticed after replacing the actuator when reving the engine the turbo would over spool. The trick to solve the problem was the to cycle the ignition key three or more times and then it will set and rev one hundred percent Like I said this was my experience on a Mercedes sprinter

[@LMAutoRepairs]

☺️ 👍👍👍

[@matejanosvarga4478]

Wow Luis you do seem to have some high maintenance customers. It would be easier for everyone if the guy had asked you to look at why the MIL is on or what he thinks is wrong with the car instead of asking you to replace and program a specific part (or, in this case, rather an unspecified one 😁) .

[@SabretoothBarnacle]

Everyone says those Bosch actuators need to be calibrated to the turbo to make sure the start/stop and actuation length is correct. Not sure if there's any truth in that or not..

[@roy2689]

I had a problem with a turbo actuator/solenoid (more actuator than solenoid) on a Land rover, I sent it to Altronics for testing and they sent it back unrepairable, the worm and quadrant teeth had worn causing it to jam, TBH if I'd looked more closely I would have seen it, I had to buy a new one, but every one wants to sell you a complete turbo (sorry mate not available separately), anyway I managed to get one and fitted and hey presto job was done, but there are different types as Luis alluded to in the video, they look the same but you have to get the right one for your turbo/vehicle..

[@fir3w4lk3r]

This is a common fault for those modules. Another weird thing is that although all the CAN-BUS hardware is there, those modules use a 140 Hz PWM signal with no feedback to the ECU for the position.

Great vid and info, just wondering what the original problem was with the vehicle ? I have a W211 E class 320 cdi done 235000 miles and had the car 14 years ! For a while now it surges especially when cold and will often go into limp mode usually when I give it some revs when cold, unfortunately I do not have a good enough code reader that shows any faults but I suspect actuator problems.

Hi luis! great work from you. I have a w211 2005 E280 cdi om642 and it have a problem of jurking or heavy power cut while heavy Acceleration but it only happens when the engine not fully warm up . I checked the actuator and it looks good to me and there is no broken pipe or intercooler. So what you think?

[@LMAutoRepairs]

I think you should scan the car, and look at some live data when the engine is cold and behaving that way... Something like that can be caused by many different things... Is yours an electronic actuator? 👍👍👍

[@kiratbhangu6972]

@@LMAutoRepairs yes, it has electronic actuator and we don't have good mechanics and electricians here soo first i have to find good one, i actually notice many things it happens after 3000Rpm and if i keep pushing the gas car goes into limp mode (safe mode) and engine doesn't go more then 2000rpm.

Without scanning it and look at some live data, it is pure guess work... You really need to that first. A good visual inspection might help, but can be a hit and miss... 👍

I have a W211 E220 170Hp, 350000 km no problems at all, but in one year mechanics changed 5 times the intercooler pipes (they were popping out from the intercooler and one time even blow), last time replace intercooler too and yesterday again another pipe pop out while I was traveling on autopilot at 80kmh/1500 rpm. No engine check on dashboard. Do you think this actuator can be the cause of this? Many thanks for your videos!

[@LMAutoRepairs]

Could be an overboost condition, though I guess the car should flag it... Scan the car, check live data while driving and see if is overboosting, if is not, I would say either the pipes have being fitted wrong or they are of poor quality... If is overboosting, you need to check the turbo charger system... the issue in this video, causes trouble codes, but proper checks needs doing to establish exactly what might be wrong... 👍👍👍

[@LMAutoRepairs]

OK... So, either the turbo itself, or othe actuator... If the actuator is intermittently failing, it can be a bit tricky to diagnose.... The turbo can be inspected, at least check that the lever is not getting stuck and it is moving freely... You can also remove the map sensor and test it, to ensure is reading linear with no spikes or anything weird... One last thing, inspect wiring, making sure there is nothing rubbing, etc... 👍👍👍

This low standard is the norm in the industry and quiet frankly it’s absolutely tolerated and perhaps even wanted. From the shareholders of the conglomerates to the owners of dealerships to the mechanics all the way down to the customers. If the customers would stop accepting these mediocre results and absolutely insane invoices something would change. Either the dealerships in question would go out of business because customers would stay away or on the other hand the quality and pride would drastically improve for the better. But as long as 99% of the world’s population is dumber than any other generation before and just takes anything presented at face value nothing will change. Quiet the opposite will happen. Worst quality, more expensive invoices. And honestly, why would anyone change without demand for change? Dealerships are legal money printing machines for the owners and shareholders on the breaking backs of their dumb and uneducated customers. On the flip side, it’s good for us who do have moral compasses point straight north. We make money at the side and the customer base who wants to come to people like us is growing daily.
