I spoke with the service writer again regarding their diagnosis Pin 14, Code 2 and their recommending replacing the EA Actuator Part #0001414925 EA Control Module Part #245456532. He implied both modules were out of spec and would fail sooner or later and the engine operation would be erratic and the car difficult to drive. Assuming diagnosis is correct, I attempted to locate them on my 124 Repair CD and braingears without success.

Is it worth getting one from a recycler (aka junk yard) or do many start failing at the 140,000 mi / 12 year age?
Do they have other name(s) I should be referencing?
Where are they located in the car and on the 124 Repair CD?
Any recommendations for good inde or Benz dealer for 2nd opinion?
