The lenses on the W210, and many modern cars, are polycarbonate. Similar to Lexan. Need to be very careful as to what solvents or chemicals are used for cleaning. In particular, avoid strong alkalis like oven cleaner as well as even isopropanol. If you use these, it could result in crazing of the lenses. Expensive to replace!
Do a search for cleaning Lexan and polycarbonate. It
should hopefully tell you what not to use, but ignore the posts in forums - they tend to suggest products that ignore the effect they will have on the Polycarbonate/Lexan. This is from one hit:

Some products which are incompatible with sheets under laboratory conditions include: Lysol, pinesol, butyl cellosolve, isopropanol and formula 409. They should not be used during the cleaning process. On the other hand, there are those cleaning agents such as Freon T.F., joy, Palmolive liquid, top job, VM & P grade naptha, windex with ammonia and brillianize which have been tested and proved to be compatible with polycarbonate materials.

In absence of any better information, I would start with mildest products like say, Windex or soapy water and a coarse rag and try and get the adhesive to ball up. If a remover seems to be needed, try a citrus based one like Goo Gone (3M has one too). Again, put some on a rag; rub until adhesive balls up. Maybe finish with Windex and soap and water to remove any traces of remover. I have had some luck on flat plastic surfaces using a sharpened plastic paint scraper after first softening the adhesive. Metal ones work better, but will damage lens.
Finally, using your thumb as Xpel suggests "may" work better if you lightly warm up the surface with a hairdryer or maybe even just leave car in direct sunlight.
