Mein Auto: 2003 530i 5spd Manual
No vacuum leaks. I replaced all the vacuum hoses and MAF boots. I also spray carb cleaner around items with the engine idling (cold!) to verify. I need to look at the wiring going to the knock sensor. It's not VANOS noise... or exhaust. it's spark knock. I'm 100% sure. I know what it sounds like. I've been driving modified cars for 13yrs. Sounds the same in a V8 as it does in a TT Supra, as it dones in a junky Malibu. It's spark knock. But this new of a car (yes 2003 new) should adjust for 89 gas. Brands do not matter. I drive about 30-40k year. I get to try brands all over the Southeast. How many knock sensors does the M54 engine have? 1 or 2? Approx where is it?
