I have been searching for a similar issue on these forums but havent come across anything the same. I have had my N54 135i for only 1.5 months and I have been noticing that on cold starts, when it idles between 900rpm and 700rpm it is a bit on the rough side. I am not too concerned with that but rather when the engine starts warm, it will hit 1500rpm and a slight clunking noise can be heard then revs plummet down to 600/700rpm.
It seems to run fine, no cels or any other issues, but I am not sure if it is fine or not? I will try and get a video later and run the BT tool on it but has anyone had a issue that sounds like this? There is no long crank just a clunk when it hits 1500rpm. Edit: it does this intermittently, sometimes it will start perfectly with no weird noise and other times it clunks really loudly.

Doesn't matter what they say.. As long as the fault is reported and investigated during the warranty period you are covered..

Change my solenoid and now is gone. I did pull a solenoid code though (2A87 - Exhaust Solenoid) every now and then while cruising. |

Just a thought, but it's not the exhaust flap closing is it? It'll be open on start up and can make a noticeable noise when it shuts.

No, its definitely coming from engine bay. I am going to take it the dealers and get their opinion. Does procede have a complete bypass or will I need to remove it before going to dealers?

but if they are investigating things in the engine bay for peace of mind I'd remove it altogether. Happy to do it for you if you want to drop by. |

That would be great. Maybe you could have a listen to the noise it makes and see what you think. When is good for you?

any more on this? I got the same issue - engine bay under somewhere a clunking noise. it's as I start up the car (cold) and as I shift into R sometimes (also on start up - i back out of driveway). But in warm car it doesnt happen. I have 325i N52, I'm not sure it has a flap of any kind.

I dont get it anymore - I think it was just because of infrequant use as the previous owner had it sitting in the garage for 3-4 months before I got it. Or maybe its still there and I am used to it?
I have a worse noise at the moment - coin stuck in the drivers sub-woofer (I think?) thats shifting around in there!! Its terrible and I cant get it out. |

Its seems to be a bit of a design flaw as they have these large openings at floor level that go straight into the sub-woofer. I have been meaning to take it to the dealers and let them sort it out.
