Hello, I have an 84 633CSi. I recently had to replace the starter. The next day, I went out to start it and the engine would turn over, but when I let go of the key the car would die. I had it towed to a local BMW shop to be looked at. They told me that the new starter was fine, the fuel system was working fine, but they did say that the Ari Flow Meter was bad. Does this sound right based off of my experience?
