Right, the ASC+T works great as it should. When i switch ignition on the ASC+T light comes on and then goes off as its supposed to do so bulbs fine. I take car out do some wheel spins and ASC+T flashes on like its meant to do and corrects wheel spin and goes back off so system works flawlessly. now the BIG BUT, I cant switch the dam thing off! i press the ASC button(tried holding down tried pressing once tried all of that) and nothing happens . Is their a common fault with the switches going wrong? Any help with this much Appreciated Regards Last edited by adam28; 02-21-2016 at 01:20 PM. | | | 02-21-2016, 07:42 PM | #2 | Senior Member Join Date: Mar 2013 Location: Virginia Posts: 104 | Interested because mine doesn't work whatsoever. | | | 02-22-2016, 01:20 AM | #3 | Senior Member Join Date: Dec 2013 Location: Sheboygan,Wi Posts: 135 | I have the same BS problem as well.Works great but doesn't shut off so for autox I just disconnect the throttle cable for the asc. | | | 02-22-2016, 07:08 AM | #4 | Senior Member Join Date: Oct 2008 Location: Los Angeles, CA Posts: 1,464 | Does the light illuminate (off position) but the ASC+T is still functional or does the light not illuminate regardless of switch position? If it's the latter, I'd assume it's a faulty switch. Switch failure is not a common problem that I'm aware of but like any switch, it does have a lifespan and being that the newest models of our cars are closing in on twenty years old, it's not unexpected for things like that to start going out. __________________ 1995 318ti Base - Cosmosschwarz/Sandgrau R.I.P. 1997 318ti Active - Alpinweiß III/Sandgrau 2013 328i Coupe - Le Mans Blau Last edited by zoner; 02-22-2016 at 07:10 AM. | | | 02-22-2016, 09:14 AM | #5 | Senior Member Join Date: Dec 2013 Location: Sheboygan,Wi Posts: 135 | Quote: Originally Posted by zoner Does the light illuminate (off position) but the ASC+T is still functional or does the light not illuminate regardless of switch position?

Ive ordered a new switch to test. Is their a way i can bridge any of the wires in the plug which attaches to the switch? So like bypass switch. This would prove the switch was faulty if the light then came on.

Just don't touch a wire to the chassis or you may blow a fuse. You may like to use a bright light and a magnifier to read the numbers. The ASC switch has a domed, gold-plated plate that contacts a selectively gold-plated circuit board. I would expect that would be fairly reliable. The switch is not sealed, however, so if somehow liquid got in there, it might fail.

Thanks mate | | | 02-22-2016, 08:28 PM | #9 | Junior Member Join Date: Feb 2016 Location: uk Posts: 6 | If its not the switch, i have not a clue what else it could be | | | 02-22-2016, 11:09 PM | #10 | Senior Member Join Date: Dec 2007 Location: Gulfport, Florida Posts: 3,208 | The switch is bad, verify using the jumper method above | | | 02-23-2016, 05:55 PM | #11 | Senior Member Join Date: Nov 2004 Location: Bremerhaven, Germany Posts: 977 | Quote: Originally Posted by adam28 If its not the switch, i have not a clue what else it could be | Seeing as you are not so far away, if it turns out to be the switch and you can me send the old one, I would be happy to disassemble it, put it under a microscope and try to ascertain what and how it failed. With a little improvisation, I bet I could take and post some photographs. I have attached one I took of an amusing, counterfeit crimping die. | | | 02-23-2016, 11:04 PM | #12 | Junior Member Join Date: Feb 2016 Location: uk Posts: 6 | I can confirm it was a faulty switch. Bridged pin 5&6 of the plug that connects to the switch and that turned off the asc as light on dash became illuminated. Thanks for all your help guys! @john Firestone, sorry mate I have already binned the faulty switch. Shame I didn't see your post earlier. I would of gladly sent it to you for investigation.

I have taken apart a few of those switches to add a green LED to illuminate the button. | | | | 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 | | | |
