A little late, but relevant.
Our R170 plastic bits tend to break down with age. On two of my SLKs I have had the displeasure of finding the door latch/actuator broken inside. It's usually a cascading problem, and by the time we detect it, many parts are broken inside. Finding another part is a problem--not just the expense, but because the working replacement is as old as the original.
I have tried various glues, and am having success with basic ABS glue used for plumbing (the original is made of ABS). With patience it can be repaired and strengthened. The key is to roughen any parts needing glue, and treat it like a puzzle. Then add extra ABS where necessary to add strength.
By the way, the ABS glue also works very well on our cracked/broken interior plastic bits.
