The LN Engineering Single Row Pro kit is what is going in my car, and is considered to be one of the best options for IMS bearing replacement (short of the LNE IMS Solution, which eliminates the sealed IMS ball bearing unit entirely--for $1700+).
So that's the good news.
The question posed above is a good one, though. Why would the selling dealer do any more than they had to? The IMS Single Row Pro replacement kit is $799, which is a LOT for a dealer to spend if there wasn't a reason to replace the IMS. I'd want to see the work order and talk with the tech who performed the work (ideally) to understand why it was done.
As stated, if there was metallic debris in the oil filter (one sign of IMS bearing failure), that same ferrous metal has circulated through the motor--including bearing surfaces + the many complicated oil passages in the M96 motor.
I wouldn't want to chance it that they caught the IMS bearing in time before it threw a LOT of metallic debris through the oil system.
