Had a second shop put in 4 Huf rde048v21
sensors and it reset quickly, correctly, and
permanently.
Returned the other sensors to the first
shop and got a refund on the parts and tax.
Glad it’s finally straight.

 

I agree with a lot of this. Waiting for the pressures to naturally drift down far enough to turn the light on is not an acceptable substitute for
checking your tire pressure weekly or at least monthly and with changes in temperature like we always get this time of year.
By the time the light is on, the tire(or tires) is at least 10 lb underinflated and has been for a while.
For a lot of people, the light IS teaching them not to bother to check their tire pressure.

The light IS helpful for more sudden drops in pressure, usually related to a puncture that can be repaired easily if you get to it promptly.

 

Emailed the sensor company, who then
talked to the tire shop, who then called me.
They say they now have the correct configuration
data for my make/model/year/build date,
and that their application tables weren’t
strictly correct for my vehicle, and they
want to try configuring the sensors again.
Will stop by late Friday afternoon or early
Saturday am to give them another go at it.

 

They are indeed on my list.
I will save the sensors and return them
to the first shop for a refund of
applicable parts and labour.
I’ve also sent a couple nasty-grams to
the manufacturer for U-Pro.

 

That’s what I thought at first, too , until I
realized it was displaying 3.5 at 35 psi
at the gauge, 3.9 at 39, and 3.2 at 32.
I think it’s a discrepancy in my scan tool’s
labeling of the units, rather than at the
sensor level.
It’ll be interesting to see what happens with
my “known to work” summer tires later this afternoon.

 

Took the MINI in for the FOURTH time. They were supposed to have an oem Huf or Schrader ordered at this point.
They said they tried another sensor set (didn't recognize the brand, but it wasn't Huf or Shrader), and they said it didn't work.
They then put in another U-Pro set and programmed it for 2008 and drove it 15-20 miles and pronounced it fixed.
I checked a scan which said the sensor positions had not been acknowledged yet, and sure enough, in just a couple
more miles, the light came back on. Tried resetting it and it took a couple miles for the light to go out, but it came
back on in a few more.

I ordered the same Huf sensors (RDE048V21) from Tire Rack that worked instantly without programming on my summer tires,
and will get another shop to put them in the winter wheels and re-balance Friday or Saturday (they should arrive Thursday).

 

It’s going back to the shop tomorrow afternoon. They’ll have several hours to work on it while my
wife and I take our two Wegie* cats in for their
annual checkups.
I think they’re going to try reconfiguring the
sensors first, and then replace them if that
doesn’t work.

Well, the tire shop had the MINI all afternoon and reconfigured the sensors, drove it several miles until the light went out, and pronounced it fixed.
I scanned it and found no data on any wheel, drove it 4 miles and got data on the wheels but no acknowlegement of the sensors, drove it 4 more miles
and the light came back on. They tried something on it again with two different scan tools that they have and since then, no codes, faults, or lights, but still
haven't gotten acknowledgement of the sensors. The light usually doesn't go on until that happens,
or if it doesn't acknowledge them for a certain period of time or mileage, then an "inactive" error occurs.
I'll have to drive it more to get to that point and see if the problem becomes apparent again, which I'm pretty sure it will.
It really shouldn't take so many miles to reset when my summer wheels and the previous factory wheels reset in about a block or two.
Meanwhile, they're ordering a different brand of sensor and will swap them in this weekend if they get them in by then, or the next
Tuesday or Saturday if not.

 

Plus the car is perfectly drivable like this
and there’s no real urgency to getting
it settled correctly.
But it is still very frustrating and I would
prefer it fixed sooner than later.
