DSC, DBC, Start off ass inactive malfunction!!!??

[johnnynguyenn]

Hey the other day i went to a party and was drove home by my girlfriend in my bmw 335i 2007. Suddenly it started to make these bumping/thumping noise that i never heard before than suddenly the dsc, dbs and startoff malfunction warnings came on. Driving is fine but theres a some what loud thumping. I checked my rim to see if there was a bent maybe and found out that it was perfectly fine but i did notice my tires not on my rim exactly(the tire isnt off or anythign). Its just slightly off and i think it might be because of a flat tire? im not sure. Also my tires are run flat and aftermarket so i dont have a tpm to check.

Can somebody help me out please?



thank you

Simple, get a tire gauge and measure tire pressure then move on from there. Unfortunately, they have not yet invented a way to have the tire pressure remotely checked from a forum.

Remember that it is getting really cold nowadays and if you have not check your tire pressure in a long time, it could be way down causing all sorts of issues not to mention being a safety issue. Just check mine at lunch and they were 6-8 psi down and I usually check them once a month or every other month. Need to do that more often when cold weather hits.

It could be, but no point worrying about the complicated stuff before you check the basics. If the tire pressure is fine, post back and we will give further suggestions for things to check.

hey so i checked my tire with a tire pressure and nothing showed up but when i tried it on another tire it showed the pressure. I think there might be a hole in that tire. If i had a flat tire could those warning be showing up because of the flat? I am planning to go get it switched today and was wondering if once i swapped out the tire will the errors go away? thank you

Hi Guys, i have the same problem. i drive 323i 2007. Few months ago, brakes started to make a squeaky sound. I didn't pay attention and kept diving.
Also i changed my front two tyres from run flat to normal tyres. So i have ordinary front tyres and run flat as rear tyres. Today when i was driving back from work, an error came up saying i have a flat type and need to checked asap. After driving few kms, another error came up which says DSC, DBC failure and Start off Ass. Inactive.
my tyres are fine, but i am scared to drive my car now after reading some horrible feedbacks from people.

can you please help me??
