2008 Mercedes Benz ML320 Severe Hesitation/Surge on Heavy Acceleration. Codes 2359 and 2510

- This 2008 Mercedes Benze ML320 suffered from a sever hesitation, bucking and sometimes lack of power. Scanning retrieved codes 2359 for Turbo Overboost and 2510 for Wastegate Actuator Fault. I found several videos which showed how the wastegate actuator failed internally with one or two small solder joints that have a tendency to fail. It took me two attempts to solder this but it seems to have worked. Also replaced the very dirty air filters.

Thankyou!
This failed a second time so we replaced it. • 2008 Mercedes ML320 Wa...
Your keeping yet another clapped out 300c on the road! Thank you for this upload. Exactly what my car is doing at 2000rpm. Going to have a look see if my wires as just as f'd.
Phillip, AWESOME information and the way u approached this problem is great thanks for sharing brother.
That's exactly what my MB 280CDI is doing. THANK YOU for making this video.
Been looking for this video on UA-cam for 2 days. Search is completely useless!
seems to be amazing video and a very logical person behind the camera
enjoyed your diagnostic methode of the whole problem
I sent my Turboactuator too Turboactuator repair in Canada they did a great job…..my GL 320 has been great since ..
Thanks for that information. Can you provide a link to them?
Very good explenation! I also have the same problem with an ML280 CDI, going to check this asap.
I'm dealing with this same issue. Same with the no check engine light. Shows low boost pressure when I scan it with my scanner and I have changed everything besides the actuator and turbo. My bucking is intermittent and not as bad as yours but it seems the actuator gives up and closes during heavy acceleration. Thanks for your vid as it seems this is a common problem with these vehicles and I'll be changing the actuator soon.
The actuator is not that bad to replace. Sourced one from Rock Auto for a decent price.
@@PhillipBailey it didn't look too bad to change. Thanks for the lead. I'll give them a shot!
I had same problem with my 2008 ml320 cdi ...problem was with the intercooler resonator which is made of plastic housing that breaks and kills your boost ...I totally removed it replaced it with a straight pipe ...my suv is 100 % better with so much power .
I’ve had intermittent bucking on acceleration for years. Always at the worst times too. Turning left from a side street, always seems to be first gear and accelerating. Motor stutters like it loses all accelerator signal. Gonna have to pry this box off and look at those joints
I'd recommend to check it for codes first...
Thanks very much for this video, I'm going to do this with my e class
Good luck. Let me know how you fare.
@@PhillipBailey thanks, I'm going to need it lol! Have scanned it beforehand and said the exhaust back pressure sensor was faulty so changed it but car still lurching, ever since It's been throwing the code for exhaust back pressure too high. Had limp mode with EML only once out of the hundreds of journeys that I've done with it but not before nor since that one time, very strange how there's never an eml light and surprised it's not constantly in limp mode.
Checking boost hoses for good measure as the turbo o ring seal had gone so imagine there's something somewhere that'll be leaking (touch wood not had the oil cooler seal go out yet) but looking forward to this little repair in all honesty. I'll hopefully get the car in sometime in the next month and get it apart for soldering.
Will let you know asap!
Cheers
Johnny
Nice work - I have the same problem on my UK E280CDi. Mine doesn't bring up a check engine light either. Mercedes perhaps just considered this to not be a problem that warrants a check light. Mine only does it after setting off on a drive after stopping on a journey. My scenario being a hot engine re-start -after stopping on the highway for a slurp and squirt. classic dry solder joint failure? I will find out
Good luck. I have found that you cam buy the complete actuator on Rock Auto for a reasonable price. Make sure the turbo wastegate is not seized though.
@@PhillipBailey Do you have to reprogramme the new actuator in again or is it plug and go?
@HonestDating it's plug and play. There could be a relearn procedure but it's not critical. I ended up replacing this entire actuator from Rock Auto even though it was still working the customer wanted to replace it. Didn't do any relearn and it seemed to be fine. Good luck.
@@PhillipBailey Thank you for your help. Much appreciated.
hello phillip i get this problem 1 weeks ago on my E280CDI om642 2007 engine :) while engine is cold car runs good but after the engine go to warm turbo goes off no and working only 3000rpm... i get this code ( Check the structural unit Y77/1 (servo mechanism for regulating the pressure of the injected air). The servo motor reports a malfuntcion) so what do you think should i try to open actuator and check wires? also on of the intercooler pipe is broken and leaking air
I'd fix the intercooler pipe first.
if anybody please with a cdi engine can you check something for me?
when you put your key in the ignition and turning to the second position without starting the car can you hear a clicking sound coming from the actuator?
thanks a lot
sorry but you havent showed the crucial part, how did you solder to copper?
Unfortunately this wasnt my issue =( all connections on actuator are fine yet still judders like this one under hard acceleration. Its not that old of a turbo either as already replaced couple years ago =(
Did you check for codes? How are the air filters? They are a bitch to access so the lube shops don't touch them.
@@PhillipBailey filters fine, about to replace fuel filter. The only code recurring is for EGR because i run a bypass on it. Have done for a long time without issues tho
Does that software program sensors as well? What software and obd adapter are you useing
I'm using a Snap-on Verus Edge with Snap-on software. It will do most module coding but not all unfortunately. Not sure what you mean by programming sensors unless your referring to module coding.
Hi I have lost my wire that connect the 2 connections on the actuator circuit board can someone tell me what wire can be used to replace my lost wire to solder the 2 connection together
I used a single strand of copper wire.
Ремонт сотовых телефонов они вам припаяют медный провод
Hey, what if you change that part and the problem still occurs, any ideas as to what else it could be
Sticking vanes in the turbocharger itself possibly.
Don’t forget Tim.. you did not put the link in the description
Thanks for reminding me...done
@@PhillipBailey thanks for video,im going through 2510 y77 actuator code as we speak.i will open actuator and check wires tomorrow.Thank you from the 🇬🇧
@@MyScotty7 if the small wires have broken loose you will need to scrape through the aluminum coating to get to the copper to solder it. Good luck.
Hay i have 2359-1 ....?
Its the most common fault !
