Continous TPMS Problem

omerfar23 · 01-07-2010, 11:20 AM

I have a 335i which continuously have the TPMS light on all the time. Its been going on since last year and I really don't understand it.

So last year I had the TPMS light come on every 14 days after I put some air in it. I thought I had a flat tire so I took it to the dealer who replaced some valve for no charge and said the problem is fixed and said I didn't have a flat tire. Well fast forward to 6 months the problem is back in the same tire. basically the the tire drops to 25 psi very slowly like in 2 weeks. i have to put more air all the time. is the tire or the valve? where is this valve can I do test to find out myself? thanks for the info and time.

Take the wheel and tire off and put it in a big tub of water. Let it sit there and little by little spin the tire around. If there is a leak or a hole or something going on air bubbles will show up.

Had this happen on my last car. One tire lost preasure slowly and I could not figure out the reason until I did this and there was a needle sized hole in the sidewall of a brand new tire!

could also be a bent rim, but you would feel shaking when driving.

dangs I thinks its the rim though the ride hasn't been any extra hard or stiff and there isn't any shaking feeling..

so the tire had no major damage nor did the wheel. There were two separate punctures in the tire. Got one plugged and other one had to be patched. Got the RFT patched ($15) and everything is fine now. thanks for all your help guys.
