I replaced the IDM on my '03 Aero today. Original (TK 3.6A 0303) lasted 5yr and 54k. #2 (TK 3.7C 0707) lasted 8yrs and 44k.
Both units failed in the same (classic) way. No noticeable driveability issues, but recurrent P-1312 fault code. Both had telltale cracks on the bottom plastic between cylinder #3 and #4. In fact I took some pictures (below), and the failures are nearly identical. The original cracked on the back (firewall) side, and #2 cracked on the front.
As a curiosity, the new part (OEM from EEuro) says TK 3.7G 1548. I always assumed the last four numbers were a date code (0303 for March 2003 and 0707 for July 2007). Anyone know what 1548 means?
Cheers,
Mr. Science
