(posted on wheel/tire section already) 128i - TPMS INACTIVE?? stock wheels?

[smeard]

Hi all! Filled up my tires to ~45 psi just in preparation of summer months. MAX psi is well above 45. Anyways, couple of days later I get a flashing TPMS light. I assume it (maybe) finally picked up a change in pressures. I measured and still read ~45 on all four corners. Measured couple of hours later (in case of slow leak), same results. I tried resetting, but instead get an INACTIVE error. I am running stock wheels and tires (tires were replaced 6 months ago from dealer I bought car from, OEM RFTs 17" staggered, no issues til now). Any suggestions? I will bring car in to my local tire place see what they say. i'm thinking sensor/transmitters in wheel well? Maybe wiring issue or (god forbid) a module issue? Should I replace all sensors at once? Have you all gotten this warning and if so what was your fix?? As far as i can tell, warning light is purely annoying and not a dangerous situation as my tires are all near new and fully inflated, so I am comfortable driving on it. Thanks in advance and I will keep you all updated.

45 psi all around seems a bit too high. Still just a little too high even if youre running 100+mph with some extra weight. I dont know if running it high would cause that. I want to say that it might just be a sensor that is messed up. My right front sensor is off an e90 and wont pick up the sensor from the front right wheel. Forgot exactly what iDrive says. Ill try to check tomorrow if i remember

I am running with a TPMS light on my 2010 Colorado. I know it is the RF because of the reset procedure for this vehicle. I am sure the battery has died. I just do not want to go to the expense of undoing the tire and replacing until I have to replace tires.

If it bugs you, replace it. If not just check tire pressures regularly like old school.

I agree 45 psi is too high.

Yeah, agree about 45 psi being too high.

On my door jamb it says: front - 36 psi, rear - 39 psi.

Edit: I have a 135i. Don't know that it's any different for a 128i, but if it is, it can't be by much.

soo am I missing something.. I have the last yr of the 135i.. here in the states..
why the fuck does ur 128 give u psi read out but my fuckin car just gives me the picture of the car with the 4 tires in green or at times red
to answer ur question.. theres no wiring from wheel to module.. it communicates wirelessly..
depending on year of car and of sensors.. they batteries could of died in a or all sensors.. thus the error..
I switched from factory rims to the older 264's and didn't swap out sensors and 2 days later got the tpms error.. I doubt if u switched tires on the same factory rims months ago.. that the tech could of possibly fucked up one sensor or multiple sensors on installing tires.. cuz if he did ud get the error within a week max..
soo I'm gonna put my money on your battery died on 1 or multiple sensors..

ebay has 4 sensors not oem brand but who cares .. people have no issues with the brand fro mwhat I hear for 150 plus shipping.. so u buy em and a indy can code the new sensors to your module..
I got quoted 20 bucks each wheel for coding..fyi
good luck.. I hate having a dashboard x mas tree..

[low135]

I didn't even put them in my new wheels lol gonna code it out so my dash shuts up about em

I'll lower the psi to about 40. i like them running a bit high because i feel like the car handles better.

As said above, I will lower psi in all tires. Personally, it is annoying but i can live with it. It keeps my other orange light company on the dash (timmy yoyo/DSC off)

I believe my recommended psi is a tad different (maybe ur running 18s and i'm on 17s??), but yes i will lower it. I talked to my friend at pep boys and had his crew check the tires and scan the OBD. found a TPMS receiving error and said I'd have to go to my indy to get it sorted. they all told me not to worry about the light and it is ok to run 45 psi , but i will lower to near factory recommended anyways.

Hahaaha no my car doesn't give me individual tire pressures (dont even have idrive), but i always have a calibrated, digital gauge in all of my cars. just habit i guess. The dealer i got it from had the new oem tires put on and didnt have an issue until recently (nearly 6 months of driving), so yes i doubt tech messed up. The sensor battery is probably dead, but either way it doesn't bother me too much. I always have an orange light on in the car anyway (dsc off), so now it will have a temperamental, flashing companion.

My last car had super stretched tires and the light was on for 4 years continuously. I never even really checked up on tire pressure haha I'm awful

i get the light but to not check? not even WEEKLY? what kind of monster doesn't do a walkaround on their vehicle at least weekly!! ahaha im jk but i personally do it weekly (including my roommate's cars, i'm such a good friend)

I probably have too much faith in things LOL I was running 215's on 10.5" wide wheels and never checked my pressures hahaha pumped em up to 70 to bead, dropped to 50 and never looked again

Hi all! VERY BAD NEWS. I left early in the AM to run some errands. Car fired right up, and I was greeted with the now usual TPMS light. Coming out of the store, hopped in the car and NO LIGHTS came on. GREAT! Fixed itself i guess. Well, that lasted until I got close to home... My car freaked out on me as I was pulling into my neighborhood. All dash lights came on (seatbelt, TPMS, ABS, CEL, BRAKE, ERROR and service) and my gauges all intermittently went out. I am feeling like this is a battery issue now. For now, it will remain parked until I can see my indy.

Pressures for 128i are 35 front and 37 rear normally, the high-speed pressures are 37 and 42. I'm actually running at 26 all the way around; it rides better, is quieter, and handles nicer with lower pressure.

I don't have TPMS sensors at all, and I have the same INACTIVE warning in the cluster after I start the car, the warning goes away after a bit, and it just dings some more, but I've lived with it through one summer and this one so far without too much complaint. I failed to code-out the TPMS from the computer, but, I have some sensors to install once these tires are toast (hopefully I get that diff soon in order to make their deaths short and smokey)...

EDIT: Just saw your last post (I should read through threads, I guess). Definitely sounds like a battery issue.

Hey bro! Yes unfortunately I had already lowered the psi to factory but car had an electronics seizure. My Indy and I are convinced it needs a battery (car is 8-9 years old, OG battery), but hopefully not an ECU or module problem . Back when I had only had the car for a month, I left my parking lights on for about 6-7 hours. Would this be enough to damage battery permanently or was it on borrowed time already? And U ran 26 PSI?!?!

Sounds like a battery issue, dead ones usually make the car go crazy with similar symptoms that you have.

Yes, it rides sooo much better, and handles well, and it's much quieter.

I am on stock RFTs. Does that matter with running lower PSI? I’m getting a new battery, do I need to have it coded? It’s $200 from local parts store.

The lower the pressure, the bigger the contact patch, the more grip you have.

F1 run around 12-13 PSI.

It may feel better, it is not.

I usually run 35 front, 34 rear.

That does make sense. As of right now, I don’t think it has anything to do with the TPMS as my car had an electrical freak out yesterday giving me all dash lights and wonky gauges. I’m thinking it’s battery related and having it replaced tomorrow. Can I just hook up anew battery or do I have to have it coded in?

Ok all so this morning decided to try and fire up the 1er. What a surprise, she fired right up no error lights at all. I pulled it out of garage and let it idle and checked trunk for battery corrosion n stuff. Well, very sad discovery. Battery looks fine but my brother must have let this old jug of water spill out into trunk area. Only about 1/2 of the gallon of water spilled, but it did not fee moist and no smell? It spilled in the rear right of the trunk (under the taillight). Maybe this caused it? What should I do now? It runs fine no errors! Any recommendations? This all started out w a TPMS ERROR then the whole electric system.
