Well, I did and didn't dodge a bullet

I had a valve stem come very slightly loose somehow a few weeks ago. Pretty slow leak. Got about 2km down the road and got the warning light. Needed the smallest of of retightening and holding air again. Have never had that before on any car.

I've had this recently, a valve stem failure somehow. However deflation on my end was almost immediate within less than 1km I was pulled over on the hwy shoulder with a obvious flat. Saved the tire but was a huge pain when it happened. Never had valve stem failure before.

Had a valve stem fail recently as well. Luckily it happened overnight in the garage, but super weird.

[CrisSilberGrau]

Yeah, looks like they put in TPMS sensors. Unfortunately, the E46 cannot communicate with those. One of your previous valve stems could have had a small leak and was triggering the TPMS light. That or there was a leak where the tire seat on the wheel and the remount fixed that.

Ditto on what everyone said. You either had a slow leak that triggered the TPMS light.

It's the yellow/red icon on the right side of the dashboard. It was solid red before they did this. As I said, I'd hold the tire pressure button on the dash and the red tire light would go out, but 30 sec or so later, the dash would BEEP and the red tire light would come back on.

Now, I held the button and cleared the red tire light after driving down the interstate and getting off and coming back and the light went off but hasn't come back on.

I don't know what black magic fuckery is going on that whatever they did fixed it, but I don't have a red tire light on my dash anymore.

FYI the correct procedure to reset the Flat Tire Monitor:

1) Check / adjust pressures
2) Turn on ignition (key position 2)
3) Long press to get the red light off
4) Short press to get the yellow light on
5) Start engine and drive off, light will turn off after some driving

If you don't know how to reset the TPMS, just watch the YouTube video I linked or RTFM.....

By not doing so, you have learned an expensive lesson.

Ended up getting the eBay used driveshaft with CSB and had it shipped to the indy. Got the car back today. Driveshaft was $300, total bill from the shop was $1416.29.

1x 252.42 for the drive shaft flex joint
1x 114.55 for the fuel filler door lock actuator (had him do that too, though the magnet is still busted)
4x 153.00 labor to remove and install drive shaft
1x 153.00 labor to remove and replace the filler door actuator
1x 150.00 misc parts

$765.00 labor, $516.97 parts plus taxes

Their rate for imports is $153/hr,

Found the invoice from the fuel pump install, so I figured I'd run that one here since you all said $1200 was too much.

$1300.85 for fuel pump and relay
3x 153.00 labor for remove/replace fuel pump
1x 693.68 for fuel pump part
1x 23.48 for the fuel pump relay
1x 0.10 remove/replace relay

$459.10 labor, $693.68 parts plus tax.

Also took it to a tire shop to get the TPMS sensors fixed as it's always telling me I have a flat, that was $230 for 4 new sensors and reprogram of the system or whatever.

Have an appointment on Friday to get the brakes looked at and then an appointment at 1pm to have a body shop look at some cosmetic stuff I'd like to get fixed and see how much that's going to hurt.

This is just sad. You are constantly getting gouged, and like an abused wife you keep coming back for more.

[maupineda]

i think the shop did not know better and sold you parts your car does not even know about. they just reset the TPMS strategy and charged you a lot for nothing.

So where on your car is the tyre pressure displayed?

My guess is they replaced all four wheel speed sensors and they or OP might be referring to them as being TPMS sensors. IIRC, a bad wheel speed sensor can cause the TPMS light issue.

Here's the invoice. They showed the sensors to me, they were attached to the valvestems.

The E46 M3 does not have any TPMS, it just uses the wheelspeed sensors. If you read your manual, you can actually see for yourself how to calibrate these so the light doesn't keep coming on. But if you haven't got a manual, see here:

I understand that. But what they did fixed my issue. Drove 100mi today and the light didn't come on.

I can't explain it.

What year is your M3? You actually have sensors in the wheels??

It's a 2005. It seemed to have fixed the problem.

There weren't any sensors in any of the wheels they said (which I understand they're supposed to be wheel speed sensors in the hubs, right?). Their system allowed them to program the new ones (33MHz I think they said) Put 4 in. Said to drive it at highway speeds for 10-15 miles should allow the sensors to calibrate and the light would go off on it's own. I did so and the light didn't go out on it's own, so I hit my turn-around point and held the TPMS button on the dash until the red TPMS light went out. It didn't come back on the rest of the trip back. Usually it'd come back after a minute or two.
