With BMW it seems there are three services (unless things have changed over the years) Oil Service - which is just that and a checkover Service I - which is a minor service Service II - which is a major service I would double check all service history stamps to check nothing has been missed though and then go for the one you think it best for the car, and your wallet 🙂

Always a good move to remove emission items on the early cars, they never did work properly and were only there for the manufacturers to gain Euro standard emissions (drive-by noise reduction valve on the exhaust is a classic example - replacement exhausts aren't equipped with this component) I used to work on a lot of American cars from the late 60's and early 70's and they had so much useless junk on them that a 5.7 litre V8 would only produce 210bhp....after we stripped off air injection, early pellet type catalytic converter, restricted inlet manifold, EVAP....and so much more junk to satisfy the Californian emissions rules. After that we were getting a respectable 280bhp output from the engine and the thing would still run incredibly clean on emissions

Hi Daniel....welcome to the Forum Always nice to see an old school Beemer Is it the pedal physically not returning to rest or is the revs that are not returning to idle? If its just the revs and not a physical problem with the pedal movement then it could be a vacuum leak which is holding the revs up
