So, i'm probably in a fail situation here, but here's a couple points before people tell me to go to the dealer:

1. I'm over 50K miles
2. The problem is just like the engine ticking nonsense. It's practically impossible to replicate for the dealer because it happens randomly


Alright, onto my unusual vehicle behavior.

This isn't the first time it's happened, but it's happened only a few times at random times.

The very first time this happened was when I got off the 22W freeway and started heading to a bakery in Garden Grove.

I had my windows down, and when i let go of my acceleration and let my car slow down for the right turn stop light, you can hear this very loud whistling noise. It disappears or becomes mute when i start accelerating again.

Later down the road, I start slowing down for a left turn stop light. Same noise as I reduce speed. Once I completely stop, the car starts acting really weird.

It starts increasing RPM repeatedly in short bursts, and I can feel the car pushing itself forward when the RPMs increase. I had my foot on the brakes, but i know if i didn't, my car would force itself into the car in front of me. I wish I could take a video of this, but I never have my digital camera with me when it occurs.

This happens to my old '93 E34 5-series too. 525i.

Anyone have any clue as to what's happening?

E92 coupe 328i or 335i? Do you use premium gas? If it's a 335i it sounds like it could be your turbos with this whistle sound you hear.Good luck finding what is wrong with your car. I am having an issue with my 06 330i. Yesterday driving it home from the dealer in Torrance, I noticed a power loss. They fixed squeaky brakes and updated software for idrive. I never had to floor the gas pedal all the way to get really moving. Also I can't install my Injen intake I just bought because if i need to take it back to the dealer they might blame the intake for whatever is going on with my car.

328i, use 91 every time.

The brakes were a PITA -__-;; I got that squeaky thing fixed too. Took me 4 tries.

Hmmm ok so a 328i with proper gas. I'd say take it back to the dealer and have them run a full systems diagnostic. I wonder if it might be a fuel related problem. Bad fuel pump or fuel filter. They fixed my squeaky brakes in 3 trys. The cool thing is I had a 335i sedan for the second loaner and a 135i convertible for the third loaner.

Yeah, but i'm trying to avoid going to the dealer by seeing if anyone else experienced this. I'm over my miles and I don't have any warranty :\

[Shazmonkee]

Anyone else have an idea of what this might be?

What did they do to fix your brake problem?

Mine were fixed after three trips to the dealer. It was the rear brake sensors. They were rubbing against the brake drum. I kept telling them it sounds like it's coming from the back. Now after a month I am squeaky brake free!
