When you pick it up, make sure you find out exactly what they did. Intercooler hose/clamp replacement or repair should be mentioned - be suspect if it is not. BTW, what was your build date? I am continually amazed at how many 320 owners are having this problem. Wouldn't it make sense to correct this at Vance and eliminate the warranty repair/tow payments. This has to be a major known issue for MB.Steve Birge said:This is my first post. I have been reading about the problem of the cooler hose which I seem to have. I own a GL320 CDI that has 2400 miles on it. I bought it a month a go. I loved it from day one but yesterday on my way home from work it started to buck as I excelerated around 15 to 20 mph. At first I thought I had bad fuel or was running out of fuel.I was able to fill the tank but still had the problem of bucking and made it home in limp mode. I called roadside assistance this morning and my car was towed to the nearest dealer which wasn't the dealer that I bought the car from. I hope they are aware of this malfunction and fix it. All your posts and experiences have been very enlightening. I'll keep you posted on my problem.
