Under certain circumstances, refrigerant loss from the area of the expansion valve pipe connections can be misdiagnosed as a defective expansion valve.
As of production date October 1993, a longer bolt has been used in the installation of the A/C lines to the expansion valve. The new bolt is installed as a precaution to prevent the expansion valve from distorting, which could cause a leak at the pipe connections on the expansion valve.
Repair Information:
Use the new bolt, M6 x 30 mm (P/N 900 074 015 02) (see Fig. 1) when repairs to the expansion valve are necessary.
The torque specification for the bolt is 10 Nm. Do not exceed this torque.
