I was wondering about ASR on the W126. Particular, 1991. I think that was the only year offered for U.S. sales.

Anyway. I do not have the caution triangle on the speedo, but if we assume its been replaced with a cluster that lacks it, how would I go about knowing if its installed.

I only ask because the car has buckets of power, but today I decided to go Top Gear on it in the rain and I could not for the life of me get the rear tires to slip traction. Also the engine bucket down something fierce, but I am not sure if ASR retards timing anyway.

Or if someone knows the build sheet code?
