560 SEL Air cells/ accumulators
 

My 1991 560 SEL needs accumulators. Is it difficult to replace them? As I am concerned about the pressure that they may contain, how should I proceed to do the job? Thanks!

On a scale of 1-10 with 10 being difficult...replacing accumulators on that car would be a 2.

No real danger, start by opening tha bleeder on the leveling valve OR just break the line loose to the cell.

Depending on your AREA (salt on roads in winter), the lines can have a lot of rust & might even require replacement.
