Hi,

I own a 2001 Audi A4 Quattro and lately have been seeing quite a number of issues. One that I'm currently concerned about is with the tire pressure in the left rear side of the car. Though I pump in enough air, the tire's just getting flat out in a week.

When checked with the repair shop guy, he says the tire looks just fine. But looks like the RIM on the inner side of the tire(i.e. rim when looked from beneath the car) seems to be broken and that might be causing the air to leak. I am not sure about this, so wondering if any of you experts might help me out here. Would it be possible for the Tire pressure to leak because of a rim breakage? If so, how what is the exact part name so that I can search to find the average cost to get that fixed.

Thanks,
Adi
