I saw something where BMW said the N55 was intentionally made more difficult to tune. Some products that promise to clear codes, might not get everything. BMW says their motivation is to maintain higher residual values. It would make sense to me that the risk of buying a tuned car without knowing about it would not improve residual values, nor would BMW want to be dealing with the problems later in CPO vehicles.
