New owner 2011 325i manual - few issues
Discussion
Hi All,
This is my first ever BMW so please be gentle
I acquired a late 2011 E90 325i 6speed manual., done 84k miles. The car has a few strange issues I've never experienced with another car.
1. When in gear ( apart from 1st ) and below 900 rpm when I accelerate the car stutters at around 1100 rpm for 2,3 seconds , then all is good and it continues as normal. This happens in 2nd , 3rd , 4th, I haven't tried it in 5th or 6th.
2. When coasting in gear , there is a mechanical whine ( grind metal on metal ) coming from the engine compartment. Could it be a flywheel or a clutch issue ? It is pretty consistent in all gears. If I put the clutch down , the noise goes away.
3. When in 4th and accelerating a strong vibration is coming though the gear stick. Doesn't happen in any other gear.
4. When idling the engine sounds like a diesel, I read on the forum that it's normal, but not too sure about that.
5. What is the best way to get the code to update the satnav ?
6. There is quite a bit of carbon build up in the exhaust pipes, should I worry about it ?
7. I attached the Bcables cable to the odb port and got these two errors, I cleared them but not sure if they are important or not.
8. My car seems to have BMW Online , but the internet browser does not connect, if my phone is connected via Blutooth it seems to get internet from it, but not sure how it works.
Thanks
Nick

8. It's because you've no subscription (i.e. it's expired) , for my 2009 335i, it was the same at the same age. This is my first ever BMW so please be gentle

On 6, I don't think so after 84k miles. Clean them?
7. I don't read German than well, can you google what codes mean?
5. Plenty of good people sell codes on E90 post , go to the UK forum.
4, I had two old E46 325's and they never sounded like a diesel. But if credible internet people are saying that, bear in mind I've read people say the V8 M3 sounded a little like a diesel, on idle, it could be well an opinion that you share.
My first thought was your in too high a gear for 900 rpm? My second was if there is some stutter, resetting the throttle adaptions might help, but with whines and singular gear vibrations, surely it's worth checking all of this out.
It's an n53 engine so does normally sound gruff at idle because of the piezo injectors and high pressure fuel pump which is beneath the inlet manifold. They can sound very random, I've given up worrying so long as it's not shaking or sounding like a bag of spanners being bounced around.
Best place I've found for n53 expertise is e90post.
Sooty exhaust not necessarily a problem unless it happens super quickly. Mine is running fine and will not soot up significantly over 200 miles. By that I mean you can rub you finger in the exhaust tailpipe (when cold) and you get a black dusting on your finger but not coated. Do it again and it's clean. If yours is sooting up like an old diesel or no DPF diesel then it's likely injectors.
N53 engines can be temperamental but get them running right and they are great.
