Engine noise on warm startup

Hi , I read many reviews or complaints regarding the famous engine noise or knocking that lasts 2-3 seconds only on warm start up after the car has sat for 1-2 hours but not completely cooled yet.I believe I have the explanation for it since I had the same thing in my old 1991 E260, simply the problem is that mercedes uses an oil pressurized system for the variable camshaft timing of the valves, there is different setups for cold or warm start guided by the car computer, in cold start system is fully drained but pressure not needed in that system for cold cam timing, in immediate restart system still fully oil pressurized so no noise, in between u hear the noise, no effect on engine life :-)
So for 60k I can't get a radio that works? Really?

We replaced our 08 ML. The fit and finish are as expected, the performance for a 6cyl is good, but...I have a 2011 Jeep Compass (I won't spend the money. It's a car, it's not a fashion statement) and the radio will quickly connect my phone through bluetooth for complete hands free. It downloads my contacts, it has voice recognition, it streams music from my micro sd card, and it streams music from my internet connections(pandora, slacker etc). The Merc won't do it. My wifes phone is the same as mine. Now while the average user may not appreciate this. When you pay 3x for a vehicle you don't expect customer service or the factory to make excuses for why it doesn't work. Disappointed for sure.

I purchased my 2012 ML350 Bluetec back in November 2011. After 2 weeks, the first problem I had was car was pulling to the right at highway speed. After left it with the dealer for about a week, they finally realized that it was bad tire which took them a few more days to get replacement. Next, I was having problem with car loosing power when driving over a long distance or for a few hours. There is no error message on the dashboard nor that the dealer can replicate. Anyway, I start documenting them on video using my phone. They finally acknowledge but still no solution for it. Along with the car loosing power, I was getting error with PRE-SAFE Inoperative error and Ad-Blue low level

Just to share my story. I purchased a ML350 SUV in 2013. Nice looking vehicle and I was ready to enjoy. Well, here is what happened. First, I had a problem with the drivers seat. They fixed that after two tries. I did hate to complain, but the vehicle cost a lot of money. Second problem. I have a noise somewhere near the steering wheel and tires. It sound like a screw was loose and the vehicle could come apart, or at least the front part. I took the vehicle in, the man said it was ok. NO. NO. I went back a week later and they kept it for 12 days. They say it was a coupling near the steering whell and the bushing. Well, they fixed that too. Still, the problem is not completely fixed.

I had my 2012 for 1 1/2 years then bought a 2014. The 2012 was so quiet and comfortable. Plenty of power, no problems of any kind. I am 68 and this is the best car that I ever had. Love it.
