Nor can I speak for Jack, but I agree, Jack...make it right from the factory. Jack, any word on your wounded soldier?

Late tonight I received word that the new clamp and hose is not working either. The hose is coming off when pressure is forced through. Supposedly the tech is working with a MB design engineer who may come to look at it.
The dealership was not very optimistic during my conversation today. I may need to start looking at a backup plan. Wait many months for another CDI that is not going work, go for a 450 or look at a different vehicle. I have a very numbing feeling right. I can't believe I'm going through this. I really like this truck, alot!

Jack, that sucks.
Who knows the reason - there are a lot of possibilities. Maybe the hose supplier used a new type of lubricant in their process and it's just too slick now. Maybe the hose mfg's polymer supplier mixed a bad batch.
On a different tact, what are the chances (have they checked this) that the hose is ok, but the pressure is way off the charts? Maybe due to a blockage/restriction on one end of excessive input pressure on the other?
Either way, it sucks. :thumbdown:

AS - that does suck major league. But I am sure things will work out. It is a good truck indeed but then again it's good as long as you get to drive it. All the best with this ordeal and hang in there.

I can't speak for Jack but I don't think he really is interested in having his tech apply a non-MB clamp or "hairspray" to solve the problem. The car is two weeks old and MB should send a replacement clamp and hose that meets their specs or spec a new clamp and hose that will eliminate the hose coming loose from the intercooler. It is a design flaw and should be rectified by MB.
I'm at a loss to understand how something like this could have made it into production.

I have a GL320 since november and have around 7000 km on it so far. It has been trouble free and the engine is starting to break-in now. I love this car and it still impresses me everytime I drive it (although I have to wrestle my wife to take it). I sincerly hope they figure your problem out because I know that in the long term you will be glad you went diesel.

UPDATE:
Nothing new other than there is something wrong with a pressure building or leaking in the 'bypass' (I was on the cell phone and didn't get the entire story). I don't understand these turbos so I'm not very good describing the situation. Going to the dealership on Monday to find out.

Had same problem with a Ford Diesel. Dealer finally got it to hold. May want to call local Ford service and ask for tips. This was a widespread problem for '05 Ford diesels. Don't know what they done to fix. I will call dealer and ask if you want.

Perhaps you have a defect in the opening portion of the wg system OR you have high pressure on the off side of the wg that prevents it's opening correctly (such as an exhaust system restriction.) The end result in either case would be the turbo spinning too much, developing too much boost (psi), and then blowing your hose off. Actually, the hose blowing off is much better than not, as running too much boost can be disaster for your engine!
For more general info on turbos, check here*: How Turbos Work

iron head vs alloy head vs block head
MB had been touting the Bluetec V-6 as the first production diesel engine in the world with an all alloy construction. I think there is an iron lining in the cylinder head though.
There is nothing wrong with an alloy block as long as it can endure the high compression ratio.
As I stressed this is not a straight 6 versus V-6 competition and the Bluetec package is very nice too. I was pointing out why I purchased a 2006 CDi instead of a Bluetec. Money was one factor as I got a sweet deal.

All alloys are fine - less weight, high strength. They do need iron sleeves in the cylinders for wear reasons. Imagine those steel piston rings scraping against alloy cylinder walls...not a good mix.

Update as I know it now:
Went by the dealership right after lunch wanting an update from all parties. I was told they were waiting on another hose to arrive and once it was installed it would be tested and I would be notified. This hose is also for the intercooler. While there I was informed that they had towed another GL320CDI to the dealership over the weekend with the same problem. I don't know the status of it other than that.
Moments ago, I was called and informed that the new has arrived, it was installed and appeared to be holding much better. This new hose appeared to be much longer and of different quality than the original. The new hose was sent directly from MB too. They test drove for nearly 20 miles without problems however, they want to drive it more and hope to have it back to me sometime tomorrow. Stay tuned.....

Wonder how many they have produced with this problem and if they are now installing the longer hose on the production line?

AS; Not owning a diesel, nor in possession of my GL yet, I've followed the trials and tribulations of the beleaguerd CDI owners. Sounds like your torment is coming to an end. Maybe MBUSA will send you a shirt or give you an extra special factory tour for your troubles.

Actually MB was nice enough to give him a free tire. It just happens to be the spare 
Jesting aside, hang in there AS. Once you drive the GL those C class are no fun.

UPDATE:
No go on the return of my GL. Apparently the hose they put on works but is not the final fix for the problem. MB engineering in CA is sending a new and maybe the first of the new final fix directly from Germany to the dealership. I will be lucky to get the truck back on Fri or Monday at this point. They would allow me to take it today but MB suggested that I didn't b/c it couldn't be guaranteed to hold so they are being cautious. I don't blame them as I don't won't to be stuck again. So the wait continues....
Also, I was informed that the Mobile, AL dealership also has a GL320CDI in for the same problem.
