"BMW's inability to resolve the 'limp mode defect'"? "Limp mode" is not a defect, it's what the ECU does when it senses something is wrong that could harm the engine. When a car goes into "limp mode", the ECU error codes are stored, then read by the dealership and the root cause is determined. It's definitely not something that's endemic to the F30 335i M-Sport.

I had an aux cooling fan fail (known problem caused by defective part from supplier), but no "limp mode" occurred, just a few warnings on iDrive. After the fan was replaced, no further problems. Once the fan problem was discovered, BMW replaced the part in production and that issue was resolved.
