But my guess would be that. __________________ 98 Avus Blue 318 ti Active clear outs all around,stealth turning signals,blue led interior lights, 35% tinted windows,K&N air filter, 12" Kenwood Sub, MTX Thunder Amp,Alpine cd changer, Leatherz Armrest,ACS Pedals/Handbrake/FloorMats & Vitesse Tuning Carbon Fiber B-Pillars/CF Spark Plug Cover, New 16" MSW Typer 14 Rims on Goodyear Triple Treds www.myspace.com/avusblueti | | | 01-23-2006, 03:42 AM | #3 | Senior Member Join Date: Jul 2004 Location: atlanta Posts: 145 | I've got the same problem now. Just came on tonight as soon as I started the car. Both AST and ABS are on. 1997 Sport 125k. For the last couple of weeks, I've noticed that it sounds like I may have a tire out of balance or the first hint of a bad wheel bearing. I can't yet feel it in the handling, but when rolling at 15-20 mph w/radio off, etc... you can hear that wo-wo, wo-wo, wo-wo (for lack of a better description). The last owner put the brakes on, but I don't know if they replaced the OEM rotors w/some cheap non-balanced rotors and that's what I'm hearing or even if it's a sympton of a worn out strut. Anyway, on the ABS/AST fault light, Bentley suggests to check all the sensors first, but I'm wondering if that out of balance tire or wheel bearing may already have damaged the "teeth" on the "toothed wheel on the wheel hub" even though its not yet very noticable. I've not pulled the sensor yet, so I have no idea what to look for and I don't want to blindly replace all four at $100 each. Has anyone done this? I normally DIY on this stuff. However, since I'm fearful that one problem may have caused another, I'm thinking about taking it to my local BMW shop (not dealer) rather than end up replacing something that may be fine and missing the actual problem. Plus these darn sensors are $100 a piece, and if I do have a front wheel bearing problem those are supposed to be a real PITA. Any thoughts on you guys that have a heck of a lot more experience than me? | | | 01-23-2006, 04:29 AM | #4 | aka Stabby Join Date: Nov 2004 Location: Mead, CO Posts: 5,336 | as a first attempt, i'd pull out the ABS sensors and just take a look at them, cleaning them up while you're in there. a couple small bolts and they pull right out. you can at least check the condition of those that way. make sure the connections are all good as well. i can't imagine the teeth on the ABS rings would have gotten damaged. if you had the ABS tool, you could likely read the codes that are stored too bad we don't have that tool in-house yet (and i think you'd be third on the waiting list or so too). the sensors are easy to replace if they find that one of them is indeed bad. i'd order from one of the dealers that gives 20% off list (like crevier bmw in CA). __________________ 1996 318ti, California package, 267k miles current mods: bilstein sports, bavauto springs, e30 m3 LCABs, solid metal ball joints, bavauto RSMs w/reinforcements, e30 3.73 LSD & halfshafts, supersprint cat-back exhaust, turner rear sway bar reinforcements, IE poly subframe & RTABs + camber/toe kits, powdercoated e36 32x front calipers, sport mirrors, H&R 28mmF/19mmR sway bars, x-brace, auto solutions SSK w/poly bushing upgrade, BMW CD43 head unit, DICE HD Radio w/iPod integration and "stealth" HD antenna, staggered style 68s, orange electronic TPMS, leather arm rest, JT Designs metal undertray acquired and awaiting install: heated seat kit, cali top switch relo, lumbar support kit, park distance control kit, heated washer nozzle kit, m-coupe rear subframe, trailing arms, differential, and halfshafts, m-coupe front/rear brakes with master cylinder, under hood light kit, mud flaps, rear sun blind, auto-dimming rear view mirror, tilt steering wheel retrofit, apexcone 5000K HIDs with 55W ballasts 2002 X5 4.4 Sport Package, 53.5k miles Current Mods: e46 m3 steering wheel | | | 01-23-2006, 06:07 AM | #5 | Senior Member Join Date: Jul 2004 Location: atlanta Posts: 145 | Thanks for the suggestion. I'll try that out first. In the least, it might help me narrow down which sensor could be faulty and save me some $$. | | | 01-24-2006, 02:15 AM | #6 | Member Join Date: Dec 2005 Location: Jamaica Posts: 62 | Mine came on and I found I had no brake lights as well. I found it to be the brake light switch causing the brake light failure. My abs light doesn't come on anymore. Don't know how connected that is but the wiring diagram shows the brake light switch running into the ABS module. | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
