I have a post in the Diesel Discussion area about my car -- however the W124 (T124) era had more Gasoline wagon's than Diesel's so I wanted to see if any of you guys had any opinions on this.

- 1987 300TD Self Leveling Suspension Fluid

Any experience you guys can share would be most appreciative but please keep it all together on the Diesel Forum since that is where it started.

I don't know how much was changed on the self-leveling suspension from the W124 to the W210. My comments are based on my experience with the W210 wagon.

The system is a closed loop. The PS pump recirculates the fluid thru the PS system to the back of the car where a pair of accumulators supply fluid to the rear shocks as needed for height adjustment. The fluid returns to the reservoir thru a sediment filter located under the cap.

The part number on the cap is probably discontinued due to age. There will be an updated part number. Check with a dealer.

When I bought my car 2 years ago I could find very little information on the system and no service recommendations from MB. I siphoned the reservoir dry, filled with fresh fluid and replaced the filter. Some have suggested disconnecting the return line and using the system to flush itself. However, the fluid in the accumulators and shocks can't be removed without some disassembly of those components.

Hope this helps some. Good luck.

I had leaking rear shocks when I first got the vehicle and paid to have them replaced and the fluid flushed so it is fresh fluid just somewhere it seems to be slowly leaking. This was very helpful by the way thank you.

I believe for the W124 one is suppose to flush the system every 60,000 miles, the reason my shocks got worn was due to water introduced in the system.
