I probably see some 200 vehicles per year with Bosch throttle bodies and I
don't recall replacing a single one. Remove/clean/replace every 80 to 100k
is typical. These are a near bullet proof component in my experience. Let
me know if you find out what is behind this. You might require a core
charge so you can get the old ones for inspection. Could be just leaking
bellows mis-diagnosed by not thouroughly cleaning the greasy backside to
see the leaky crack.
