So This past weekend I parked my car in my friends driveway, reversed in. The driveway is at about a 30 degree incline. Car was parked there for about 6 hours. Go to start the car and pull out and the TPM sensor goes off for left front tire (low tire pressure, yellow on the idrive). Went to the corner gas station, checked the tire pressure, pressure okay. Drove home with the sensor still on (only 5 miles). Decided to let the car sit and see how it looks in the morning. Morning comes, tire still inflated and TPM message in still on also. I decided to reset the TPM sensors (I read in the manual TPM sensors can get set-off by snow chains or traction loss/uneven tire revolutions). Figured either being parked on the incline or pulling out of the driveway might have set off the sensor. After reset everything reads fine. No more error code, all tires are green via Idrive.

So my question:

If there was truly a flat would the tire be deflatted already (been almost 48 hours)?
Should I still go to a tire shop/dealer and really get it checked out?
Was it wrong for me to just reset the TPM's? Are those sensors programmed to stock/manufacturer's numbers and will go off if not there? If the left fron tire was deflated and I reset the TPM's, would the deflated pressure be the new default normal TPM pressure?


thanx in advance....

I will take the no response as a good thing....

Did you hit a bump or dip or anything in his driveway? or on his way into his driveway?
Those sensors are very tricky and sensitive. When mine kept coming on in my old 535, i would go through the I-drive and reset it and it would be fine. I dont think you need to take it in unless, you feel that the car is riding different or you see a decrease in tire pressure!

I can't explain why the alert went off in the first place but right now, as long as all four tires are inflated properly and you've reset the system, just wait and see if you get any other alerts in the next few days...

thanx for the advice bmwfan05 and rudy...will keep you posted...

Any warning since G?

Nope, none today. I stopped by the tireshop next to my work (firstone). Checked all my 4 tire pressure's. All were low by about 5 psi. Fronts were equally 28psi, rears at 32psi. The guy went ahead and put some air all 4 tires, fronts at 32psi, rears at 35psi (reccommended pressures). Reset the TPM's again and we shall see. The guy at firestone said a pothole or bump could had set it off...or backing up the inclinced driveway might have done it, but that's the most unlikely of causes. ..

Do you have any advice for me on whether to get the clear bra insalled on the hood of the Alpine White 535? I don't see much comment on the pros and cons of it. Colorado may lead the nation in windshield replacements, tire replacements and hood rock chips...thus, the idea of the extended clear bra. Thanks for your thoughts!

PM sent my friend...

Gene- I never got a PM from you on the Bra. Thanks.
