TPMS Question

Hi All,

I just installed a set of winter wheels and tires ordered from Tire rack and silly old me figured, ahh... why waste the extra $40 bucks a wheel for the TPMS? I will just use the trusty old tire gauge.

Well most of you already know where this is going. Now the TPMS light flashes and stays lit every-time I start the car. :| Is there any way to disable this? a fuse that could be pulled possibly? I understand that no harm will come from the light being illuminated, it is just an annoyance.

I cant believe I did not think of this while purchasing the wheels and tires. :headbang: On a lighter note they look pretty good for some cheapies, They are the same rims that AlanL put on his coupe with a set of the Dunlop winter sport M3 tires.

Any suggestions?
 
Well - as of this last week I am awfully glad I did install the TPMS with mine.

The icon indicating that a tire was inflation challenged came on the other morning when I was going to work so I pulled over under a street light to look. Couldn't see anything obvious so I went on to work and checked again under a light in the parking garage - still couldn't see an obvious issue so I yanked out my tire gauge when I got home that evening and found that the driver's rear was at 20psi. I pumped it back up and after examining it with a light found a big chunk of metal sticking out of it.

I went in to a tire dealer the next day and when we got the tire off we found a huge metal shaft that had gone through the tire. Turns out it is so large (0.275" in diameter) that we can't patch the tire and I am waiting for a new one from TireRack to get drop shipped to my local tire store so I can get it replaced. I have no idea what the metal shaft actually is - the end that protrudes into the tire interior is about 1 1/2" long and has a broken tip while the end sticking out on the tread side is well flattened from the road so no details there either. I'll see if I can get a picture of that bad boy (and post it of course) when we yank this tire back off again and replace it.

I have been driving around for the last 2 days knowing this is still in the tire and it is interesting to observe how the TPMS works. The dash light indicating that my tire is inflation challenged will go on again anytime the tire is around 24psi and goes out again as soon as I pump it back up. I am finding it kind of comforting to know the system is being monitored like this now. I might not have spotted the tire being low until it had gone down far enough to cause sidewall damage and possibly damage to the rim. The sidewall damage wouldn't have been an issue in this case because this hole is so big the tire is toast anyway but for most nail/screw punctures that could be a point of concern.

Now if I had just plunked down the cash for the Road Hazard insurance when I bought my winter tires in October.......
 
Funny, i got the road hazard insurance but not the TPMS and I am already regretting it. i know you can Purchase them after market I am just a little peeved at myself right now for not getting it the first pace. Do you think the dealer would gouge me to them install it after the fact?
 
If you have a reasonable installer you can go to one option would be to grab a set from Tire rack and then ask your installer to put them in. The TPMS monitors with stems were right around $200 and you will likely incur about $15-20/wheel for install/mounting/balance.
 
You know between the 2 of us we both did a nice job of shooting ourselves in the foot with our winter tire purchases :dizzy:
 
They shouldn't charge any more than the cost of mounting/balancing, I PMed you about a possible solution ;)

I know...live and learn, right.
Check out this thread on E90 post. there is an after market company that sells an adapter for $90 a set

That's for the adapter, and not the actual TPMS sensors. Please correct me if I'm wrong, but the adapter shown on that website... allows TPMS system to be mounted on a wheel that isn't TPMS friendly.

The cheapest I've found for OEM TPMS sensors is ~$188/set from Tischer.

Thanks to wrh3 :thumbsup: for the assistance, I now have a set of TPMS from a 2007 M///coupe on the way. Problem solved. :D
 
Ok, Thanks to WRH3 I had a set of TPMS installed in my winter wheels today at the local dealer and this is what they gave me to drive for the day.
A 335i twin turbo
I have never been a huge fan of sedans but this car has seriously made me think twice. It was faster than my Z for one ( which made me long for an M/// all that much more ) The power delivery was smooth, linear and available all throughout each gear. A joy to drive, no turbo lag whatsoever and it handled almost as well as the Z.
Very very nice.

If I did not love the lines of the Z so much I think I would be seriously considering the 335 convertible as my next vehicle. :thumbsup:

I know what you mean, driving my wife's 335i is what got me in the market for a Z4M ;)
 
Test drove a 335ixi before the Z4. Only reason I bought the Z4 instead was the wife loved the 335xi (she would have stold it a gave me her wrx). The 335xi will be our next family car. As far as the TPMS senors go, I just bought a set of winter tires for tirerack and they sold them to me for $152.00....
 
I am still a little curious to see how the turblows hold up on the 335i's. I had a 2001 Audi S4 biturbo and the extra plumbing to make the joys of boost work on that car were more of a headache that I was willing to put up with. I have been happily enjoying less engine maintenance with normally aspirated cars ever since and am still keeping my distance from the siren song (literally) of b00st.
