3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
I have a 2003 325CI
Sports package, and premium package, with xenons and silver trim and grey interior...YUMMY
Needless to say extremely happy, but I have a couple of issues, which Im currently having problems....
First: its an awful smell when the AC turns on, Ive done the evaporator cleaning process twice at $150 the first time, free the second time scince I bitched that it didnt go away, and the problem persists, Ive gotten 2 2004 325 4door loaners in the process and one smelled like piss when the AC turned on, and the other a moist smell.... They dont admit to it, but is it an inherent problem in these cars if its really hot outside? I live in Miami Florida, and when its cooler outside, (when its raining maybe) nothing smells, only in extreme heat.... They should offer the cleaning service for FREE!!!!! this is very embarrasing when someone climbs in the car, clients, new girl, family...etc.. I find myself making excuses for BMW stench....Not happy about that.... Any help would be appreciated!
Second: the amount of brake dust is just unbearable to me, I know Im a bit obscessive compulsive, but damn, I clean them to perfection and no more that 48 hours passes, barely any driving, maybe once or twice a day, no large distances, and they are filthy.... BMW says, "deal with it", "You want it to break bad and look good?, or vice versa?" ....HMMMmmmm
I WANT BOTH...LOL This is a beautiful car to have all dirtied up..NO WAY!
I mean, there has to be a logical solution...Ill get the best break pads on earth if thats the case as long as I get performance and low Brake dust...BUT BMW has to approve cuz if not i dont want my warranty to get messed up.... any suggestions?
As for the a/c stench...I would check the filters. I'm not positive on the 3-series, but on my 528 there two of them located by the firewall under the hood. They are recommended to be changed every 10,000 miles. If your's somehow got wet I could see why it would stink on a hot day. For the brake dust, just try out a different brand of brake pads. You can get some performance pads, which greatly reduce dust...however, in my experience they tend to be really harsh on your rotors.
Try taking a can of Lysol room deodorizer spray, and with engine running and AC on(NOT in recirculating mode) spray the Lysol into the air intake in front of the windshield. I use this method to kill the mildew and stuff that tries to take up residence in my system.
Brake dust, ah yes, welcome to the world of BMW factory brakes (probably PAGID), though they brake great they sure do dust. I took my factory pads off and replaced them with PBR-AXXIS (they make both organic and semi metallic) and Voila, no more dust. They also brake just fine and I have a 1988 750 so she is a heavy one to stop and they will not cost you a lot of money, about $45.00 per axle for my car.
ya the smell is a mold that grows in the AC, if you have been running the AC you should just run the vent afterwards for a few miles to clear out the moisture that is left behind. this will stop the mold from coming back. then try to kill the mold with a cleaning from the stealership.
i replaced with the stock pads with hawks replacement pads and now i get almost no dust, it makes a huge difference.
these pads also brake better, and they claim to wear the rotors less
the computer automatically put the vents on recirculation (so that you get the requested tempo sooner) this causes the stinky mold to accumulate. i'd periodically "air it out" by turning the auto control off, and giving the vents full blast with ac on and some heat.
hawk pads: i put hps on my car and noted no difference from stock. then i tried hp plus, and imho they are fantastic. also, both compounds work COLD so there is no problem (the hp plus is advertised as atrack pad, that is boloney). the hps is quiet and hp plus is loud (squeals), and dusts more. also the dust is metallic, so it really imbeds itself in paint.
the car at the same time got slotted rotors, and steel braided lines (made a difference, pedal feel is noticeably better).
