Has anyone had throttle body issues with their 1999 E39? Know anything about a mere spring that needs to be replaced versus entire throttle body? Apparently the E39's don't typically have issues with this, but mine does, it's undriveable & sitting at dealership in Vancouver. Had to leave it there and fly back to California. Part is CAD $1100.00 + labor at $122/hr. Have owned this E39 since 2003 (2nd owner) and it had 48K miles on it at that time. In 15 years, have put approx 100K miles on it (6000 yr). It has been gently driven, meticulously maintained & repairs done promptly. Had it checked out thoroughly before Labor Day road trip from Newport Beach to Vancouver (1350 miles). 1st day, drove 9 hours with stop & go at rest stops, gas, etc. Upon arrival at hotel, parked to check-in, then tried to start to move to designated spot & engine dead. Tried a few times to no avail. Waited a few minutes and tried again...presto! It started. Next morning, started just like usual and proceeded
to drive another 8-9 hours with no issues. Used cruise control a couple of times. Third day, drove another 8-9 hours and made it to Vancouver safely. Next morning, it started but sounded rough & display on dashboard showed check engine & EML. Gas pedal seemed to skip a beat when depressing almost like an air bubble of sorts. Engine sounded rough. After turning off the engine, heard about 20 tapping sounds coming from drivers side. Connect a decoding device and error code showed throttle body issues. Took it to regular dealer (price less than local repair shop as they give discount on parts and lower labor rate for vehicles 6 yrs and older) and dealt with shop foreman who has been working on these cars for 40 years. He tried replacing the cables to the throttle body (took 2 weeks to get parts as had to order from Germany), but unfortunately didn't fix the problem and now suggests replacing throttle body altogether (that's another 14 days waiting period for part to come from Germany)...
