Blown Turbo on W164 ML320
Discussion
Hi,
just wondering if anyone else has had a similar problem. Not necessarily with the same car (the turbo units may be the same of different models).
To the point,
My car has just gone into the local MB garage with a fault.
They have called to say that the turbo has blown and the exhaust manifolds have cracked. Repair bill of £3-3.5k please!!
Now, this is on a W164 ML320 that is 5.5 years old and only has 43k miles on the clock.
To say I'm not happy is an understatement!!!
I just don't get how the manifolds have craked. To add to this the dealer had the turbo out last year for the inlet manifold actuator (think it was) so I just wonder could they have messed something up there?
So has anyone else had a similar issue?
I'm asking the dealer if written to MB is a course of action. Not a happy man here .

The inlet manifold actuator you refer to is the inlet port shut-off motor. This sits in the middle of the "V" it joins two linkages, one on each inlet manifold.
It would be very rare for both inlet manifolds to crack, but likely that the linkages have broken which do not come separately from the manifold.
The inlet port shut-off motor is a common fault on these, they usually fail due to oil contamination from a leaking turbo seal as they sit just below.
If you go ahead with the repair ask to see all the old parts then you can query the cracked inlet manifolds if there not.
I presume you took it in for engine management light or a lack of power?

Hi, the problem you have listed here is a known fault by Mercedes & as far as i am aware there as a service bulletin available to Mercedes Technicians highlighting this problem & the necessary checks/repair procedures needed to be taken.
From what i can understand the exhaust manifolds have an internal liner fitted around the flange area that breaks up & is then blown out through the turbocharger resulting in damaged vanes in the turbo which results in the need to replace the turbo together with the exhaust manifolds & necessary gaskets etc.
This is a totally different problem to the one described by Pistnbroke which as is a more common problem occuring on the 642 V6 diesel engine. An oil mist basically seeps past the seal ring from the air intake on the turbocharger which in turn drops down onto the inlet port shut off motor. After a period of time the inlet port shut off motor fails & requires replacement & as previously said the turbocharger has to bew removed to gain access to the motor.
Unfortunately it seems you have been really unlucky with your particular vehicle & all i can suggest is that maybe if your vehicle doesn't have a warranty you try ringing Mercedes customer services & see whether they will give any goodwill payment towards your repairs.

Spot on. The dealer has said the inner skin has broken up. An engineer is turning up today to look at the parts. Now, he has lied in the past so I have to prepare myself for the same again. It has taken a stupid length of time to get this far (ie, establish the fault and get an engineer to inspect the part). Warranty direct do not move very fast and need constant hounding.
Fingers crossed it's covered. A common fault to me is a design error and one MB should cover. Poor design shouldn't be at the cost of customers.

Hi guys
Just reading about the the blown turbo on the merc 320cdi, I have the cls version on a 2008 model which I have had for the last 15 months ,I bought the car with 16.700 miles on the clock at just over 2 yrs old. I took out a service plan with Mercedes and had full service done on may 24th this year,with 22.665 miles on the clock.
2weeks ago the engine management light come on and I noticed that the engine wasn't responding when putting my foot down but was still driving ok.
Took the car to Mercedes Benz in Edinburgh where I bought the car left the car with them, received a call later on in the day to say that the O2 sensor was faulty along with the filters being blocked, I questioned about the filters and was told that they either hadn't been fitted properly and were blocked. I told him that during the service in may that they had all been changed.
So I was now told that I wouldn't have to pay for the filters but for the O2 sensor £440
This was changed and with in an hour I received a further call to say that there was a new fault coming up and that they think that it is a blown turbo. As there was some metal filings in the inlet manifold.
Two days later I received a call to say that MB would give a goodwill payment of 90% of all the work as this is an unusual breakdown of the engine components. Total bill of around £3000. I accepted this and surely the work was done
Went to pick up the car on Monday and received bill for £785 , this was for the £440 for the O2sensor and the 10% of all the other work involved which was both exhaust inlet manifolds ,new turbo,exhaust inlet shut off v/v seals bolts and what ever to get it back.
MY question is would the O2 sensor have been damaged when turbo was blown
They have told me that the exhaust inlet manifold was cracking around some welded edges and fragments of metal went through the turbo and knackered it causing all the bother.
I should have asked to see the broken parts but because of all the arguing about the price it set me back a bit
Could someone tell me about the sensor.
I know that it could have been a lot worse for me regarding the cost but for a turbo to go on a 23500 mile merc is not good
Thanks bob walton

Dear Sirs, I am very new to this forum but just experienced the issue perfectly described on 11/03/2012 by MBTech01 (it just happened to my ML 320 CDI W164 2006 148,000km)From what i can understand the exhaust manifolds have an internal liner fitted around the flange area that breaks up & is then blown out through the turbocharger resulting in damaged vanes in the turbo which results in the need to replace the turbo together with the exhaust manifolds & necessary gaskets etc.

"...exhaust manifolds have an internal liner fitted around the flange area that breaks up & is then blown out through the turbocharger resulting in damaged vanes in the turbo which results in the need to replace the turbo together with the exhaust manifolds & necessary gaskets etc..."
Would anyone have experienced the same issue? Did Mercedes agree to fix it free of charge? Would you have the reference of the Mercedes Technical Service Bulletin stating this known issue on ML 320 CDI W164 2006?
Thank you very much in advance and my apologies in case my post is not perfectly within the guidelines as I need an urgent reply!
I've got the same problem on my 06 CLS - owned since new, full MB service history. 93,000 miles.
Car will hiccup now and again, but a few times has gone into limp mode ( but no engine warning lights or fault codes on an OBD reader) but returns to normal after one off and on. Inlet port shut down motor replaced already last year.
Dealer diagnosed inlet manifolds breakdown and recommended new manifolds and turbo- £2,900. Tried everything with MB but they won't contribute, even given faultless adherence to their service regime and this seemingly being a known issue, at least with early V6 diesels. Even threatened to p/x against an A7 but it didn't work!
However, car performs faultlessly between episodes, suggesting the turbo is so far undamaged - on the basis manifold and turbo replacement is standard MB protocol to avoid repeat breakdowns, and apparently very small particles causing the turbo issues (rather than great big flakes crashing into the vanes) I'm taking a chance on getting just the manifolds changed (£1,000) and hoping I get another year out of it before chopping it in. Worst case is I will swap in a Garrett turbo bought outside MB.
Pretty disappointed with MB's responses, particularly as we have 3 of their cars in the family, but friends have had not dissimilar issues with BMWs and Audis without manufacturer contributions, so resigned to it being par for the course with complicated German vehicles!
