Observe tightening torques for different gasket versions A union nut (2) which is tightened incorrectly leads to wheel leaks or damage to the valve body (3) or TPM wheel sensor (A69/1 to A69/5).

On disk wheels model 211, 215, 220 and 230 (all to 12/2002) may only valve bodies (3) with hump gasket (3s) may be fitted otherwise the wheel will leak.
