[Sandye90m3]

Hey everyone, hope the you and the M's are well. I recently went to my friends cabin which was about 500kms away. I arrived their, and the car drove beautifully. My 2009 e90 M3 DCT was parked for 3-4 days and I started driving back. The issue, I believe started here:

I was driving going somewhat downhill and when I would take my foot off the accelerator the car would engine break by itself (not to sure how to explain it, but it happens to every car and most evidently in the M3). However this time, when I let go of the accelerator, it took the car a couple of seconds to start engine breaking. I would ease of the accelerator and the car would seem like it's coasting in 7th (without the engine breaking) and then all of a sudden I would hear a little bump, coming from the back of the car and then it would start engine breaking. It would happen continuously if I tapped the throttle and let go.

The transmission has felt a little bit more clunkier ever sense.

And most recently if I am driving the car a little bit hard, I hear a little whine coming from the tranny. It's a very faint whine, however I thought I would just put that out their.

After I am done driving, and step out of the car after I turned it off. I would hear some liquid splashing on a very hot pan (bare with me, it's the only way of describing it LOL) and then start sizzling from the engine.

Also, sometimes when I'm driving, I would upshift and the revs would not dip at all until a second or two later and I would get a little bang from the back and then the car would be in it's next gear.

One last thing to mention, if I am stopped. Sometimes I would just take my foot of the brake and put my foot on the throttle and the car would bump forward (as if some iron man gave me a slight boot from the back of the car) and then off I go. It is a very subtile bump and I'm not to sure what it is. I'm pretty sure it's a differential problem but then again, I don't know to much about the mechanical parts of the car.

I don't know if I'm being paranoid however I never felt my car act this way. I just crossed 25,000kms on it and I have had the transmission replaced at 13,500kms and 13,550kms (back to back because when it was replaced the first time, the car still had the problem). I hope someone can help me out. Maybe I'm just being to cautious, because other than that the car is pulling as hard as it was since day 1. One day I said, if there is anything to go wrong, it will go wrong if I put my foot down and let the revs build and then dump the clutch at 4K mark. Mind you, this is what DCT does if you put your foot down past the button on the throttle when you are at a stop. Even after that, the car drove perfectly. Maybe I'm driving the car like a granny and not hard enough?

Thanks guys, please help me out!
