W116, BENZ AID - COMMON QUESTIONS AND ANSWERS

ACC demons

Whats going on? I've a 1984 300D. The heat works as normal for a few minutes after startup, then all vents close. The only setting that gets air back through the vents is AC/Cold. However when rolling the dial back to hot the vents close again.

Rear suspension 1987300SDL & 1982 300SD

I have 1982 300SD with about 250K and a 1987 300SDL with about 400K on original engine. Same problem with each. Get excessive tire wear on inside of rear tires. Have replaced axles, rear wheel bearings, spring seats and installed HD Bilstein shocks. Problem is improved but still get wear inside. Do not carry excess weight in trunk.
