Tire pressure monitoring...

[944boy]

That sucks they don't offer loaners.

I generally don't trust TPMS due to their general lack of accuracy. But it is good to know if a tire is going flat. On such nice wheels I would suggest investing in a good gauge and keeping an eye on them every now and then.

32psi sounds better for a 19".

Husker... I feel what you are saying. The dealer I bought my '05 from said they changed the oil, I believe them, but its a used chevy dealer. As competent as they are I have no idea what they used. I plan on changing the oil in 3K or less miles. Good fluids are important too.

P.S. how does the boxster deal with the rough NO roads. My 944 was not happy with the potholes and rough/unevenness. I bottomed out a number of times when I was there.

Good luck and I hope it all works out!!

NO roads are not the best for this car. That's probably why SUVs are a lot more popular here than sports cars. I have to be really careful to avoid potholes. I also got a tire/wheel warranty that covers just about anything except for me hitting a curb.

LB, I'm not referring to the outside temp in NO when I say take a cold reading. I mean take the reading before you drive your car for any distance. Just like an engine, the air in your tires will heat up when you drive your Box, which causes it to expand. Your pressure will then show a higher number if you measure it after driving the car (expanded air = higher psi).

As far as the fluids go, in most cases Porsches require synthetic oils (oil, pwr strg, etc). The antifreeze is typical European in that it doesn't contain phosphates but most of the popular brands sold in parts stores contain phosphates, so they won't work (even if you drain all the antifreeze and replace with phosphate a/f). In general, what your Dad may have in his garage probably won't be the proper fluid for your Porsche.

I took a reading and it's 33 front, 38 back. I think my dad told me the wrong thing when he told me 27. I didn't add any air just now, just checked the pressures, and now the TPS system is telling me that it's resetting or something so I'm going to go drive a bit and see if it resets itself.

LoveBunny,

The TPMS will show a -4 even if the tires have similar pressure if it over 4 psi below the recommended pressure. So as you figured out, 27 is below that level and you are getting the warning. It should reset itself rather quickly now that you added air.

I didn't add any air today though. I just checked the pressure and discovered that basically the 27 my dad told me was just him forgetting what it had been. The message I got that it was still acquiring the pressures has gone away and the stupid -4 warning came back on, so I guess I'll bring the dang car in tomorrow morning.

The dealer has informed me that I was supposed to have 36 in the front tires and 39 in the back. I'm not sure how I was supposed to know that since the door panel says 32 and 37, but apparently that was the problem. I haven't picked it up yet, but I'm sure they'll probably charge and arm and a leg to put some air in my tires.
