ABC Warning Lights

I bought 2003 SL55 AMG from a friend with 9000 miles. He told me that these lights kept coming up since the first day he bought the car. His dealership tried to fix it few times but the the warning message kept coming back, usually at the beginning of the rides. They finally told him that it was a "computer error". The height adjustment works fine. Anyone out there experiencd the same issue? Thanks very much.

Thats unacceptable. Is it a red warning in the cluster? It should be easily fixable. What are the fault codes for? The most common issue seems to be the plunger travel sensors within the suspension strut. Number two would be system pressure too low. Most commonly caused by a leak, faulty hydraulic pump, or low fluid level.

no, they are the low priority blue lights, i never had the red ones come on yet. The car seems to drive perfectly fine and I see no change in the height stationary or moving. Also i checked for leaks and could not find any.

The problem can be fixed with electrical tape. Cut a small piece and put it over the warning light.

I had this. Strut had to be replaced 'cause the sensor can't be changed and the strut was good. Danm, cost me around $2.000 to fix.

Graham1965,
Which system/software are you using? Where did you buy it and about what did it cost?
Would you recommend it?
Thanks, also new here and to the SL55, but very capable DYI'er.

If you do not mind being limited to working only on cars c. 2014 and older, then this with a Dell D630 laptop sourced from eBay may be a good choice. Total cost: About $320.

I'm wondering where someone can get a new travel sensor without purchasing a complete strut. The M-B dealer parts department does not sell the sensor seperately.
