I need a recommendation for my situation. I bought a 2018 BMW 530e with 59,080 miles from a private seller who acquired it from a car auction at a private school. The school provides cars to directors and auctions them every five years. The car's service history includes: December 2019: Minor service (oil and oil filter change, micro-filter) at 21,000 miles. May 2021: Major service (oil, oil filter, air filter, spark plugs, micro-filter change) at 41,000 miles. According to the school’s auction administration, subsequent services were performed by their handyman using BMW parts, not by a dealer, and they cannot provide a detailed service history for these. The iDrive system indicates that the next service is due in June 2025 or in 11,000 miles. However, I purchased a three-year protection plan that requires servicing the car every 12 months or 12,000 miles from the plan's activation date. Given this situation, should I pay £800 for a service at a BMW dealer now, or wait until the iDrive system indicates service is due in June 2025 or in 11,000 miles? Can I trust that the school performed the services, or is there a risk they may have simply reset the iDrive service dates? Is it possible for anyone to reset iDrive without servicing car?
