1st Gen R50 Cooper Most liked posts in thread: Tire pressure light issue

Sorry I did not realize you have gone through the steps. Can't see where going back the uninformed tire dealer is going to do anything for you, except maybe raise your BP.

Check & see if the button might be stuck in the down position. I have read about that happening.

 

Sorry I am on the East Coast outside of Philly so I don't know of a shop local to you but someone local may know of one.

As for the brake idiot light, It should go off when you twist the wires together and turn the car back on.

 

^^^ That's odd and it should not be wet. Does your car have a sunroof?
If yes look at the rear drains. You can find them by opening your rear hatch and look in the top right and left corners. If they are open you can check the seals around the hatch on the side that is wet.

Also check the battery box. I would remove the battery and check for water and dry it.
There is a drain plug in the bottom of box make sure it's not missing. Also take out the carpet and set it in the sun to dry.

 

Yup I have had this happen to me a few times in the past when it was very cold and my car had been sitting for a few days.

(I do the below process while driving.) :crazy:

Hold the button in while driving.
Push in the clutch and coast.
Release the button and turn off the car by the key and put it back on and let out the clutch and it restarts and the light is gone.
High speed tire light reset with a bump start. :eek6::lol:

 

Yeah I think you did it wrong. :lol:

 

This is very typical on all vehicles with TPMS specially during winter. Have the sensor ID checked at any walmart or your nearest auto supply like autozone, most likely tour TPMS module needs to re learn the sensors on the tire.

 

Thats a good reminder but the primary function of the ABS is traction, whether stopping , accelerating, turning and turning with brakes. BMW came up with a study among german driver's habit of hitting the brakes, the result was surprising, 80% of drivers do not utilize the brakes properly and it was determined that BMW ABS was more on handling than anti lock braking system so to compensate for the braking, out came the pre charge pump which charges the pressure going to the ABS but then again as BMW could not resist also integrated their traction control on the pump. On the mini, the ABS and TPMS have their own module and totally independent of each other, the symptom that you are probably looking at would be a hall effect symptom.

 

The discussion here is not about the ABS function, but what we are calling the "ABS sensor". More descriptively, we should be calling it a rotational wheel sensor. The sensor readings are used by both the ABS system and the flat tire detection system in 2002-2006 MINI.

That's quite curious. Without examination, it's hard to speculate whether the two might be correlated. The general rule of thumb is that the brake pad should be thicker than the metal plate it is attached to. I believe that the brake pad wear sensors in the MINI are in the left front and right rear brakes. If those are okay, than something happened to one of the brake pad sensor wires.

Yes, you can bypass the brake pad wear sensor but nevertheless it should be working correctly on dawnie's car, and something is amiss.

 

That depends. dawnie said the brake pads appear new. Twisting the wires together would work if the pads had been replaced without replacing the sensor wire. However if the sensor is intact, there is a break further up the line. There isn't enough information to go on at this point.

 

How much moisture are we talking about? You have a leak somewhere. It should be completely dry -- no moisture at all.

 

I followed the typical instructions and cleared mine on my '03 R50, but it didn't clear while driving around right after as per the details. Instead it cleared the next morning after the car sat turned off all night.
