Pre-MOT Inspection Checklist for Mercedes-Benz AMG Sl Owners
These checks follow this Mercedes-Benz AMG Sl's own most-recorded failure strings, starting with what a tester is most likely to flag on a Mercedes-Benz AMG Sl.
-
the shock absorbers — “shock absorbers has a serious fluid leak”
Press down hard on each corner of the car and let go. It should settle in one bounce; if it keeps rocking, or you can see oil weeping down a shock absorber, that is the fault a tester will find.
-
the wipers and washers — “wipers blade defective”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
