ever since i got my user 530, tire pressure light keeps going off about once a week and the pressure is fine in all wheels. The car is at the dealer for the third time and i got a call from them saying that they will be replacing a DSC module, which might be related to the problem. They also mentioned that tire tread varies between 4mm and 8mm and that could also cause the light to go off? i find that hard to believe. It seems like they are still not sure what's going on. But i hope replacing that module will fix the problem. Anyone here had the same issue? any help is appreciated.

 

Had the exact same issue with our 2005 545i when we had to replace one of the tires at ~25K miles. Retired it at 36K but had issue to the end. Good luck

 

Well, got my car back today. They also programmed the car with progman version 29.1.1. The comments are showing tire tread at 4, 5, 6 and 8mm and they said that they recommend them to be replaced. I did speak to the SA about this, told him i bought the car 2 months ago and it was CPO. He said if the problem comes back, then it's for sure related to the tires, and he might be able to make a case out of it and maybe replace the tires.

 

I had this same problem when I had to replace a front tire that was ruined by a nail. It lasted for about three months before it stabalized. The alarm would go off about once a week, then it went a longer and longer time period until it stopped. I check my tire pressure quite frequently, so I got in the habit of re initializing the FTM about once a week before it went off. Even though I knew it was probably a false alarm when it went off. it always bothered me to have the alarm sound and not be sure if it was for real, especially when I was on the freeway. By re initializing at routine intervals before the alarm went off, I avoided this happening on the freeway or when I was in a hurry to get somewhere.

 

well, it turns out that one of the tires did get replaced right before I bought the car. So, most likely that's what it is. In this case, I am anticipating the light to come back.

 

Well, it's been 3 weeks and well over 1000 miles since the fix, no FTM light. Looks like it's fixed thise time. SO, if somene does have the same problem out there, most likely it's the DSC module.
