I don't know the answer, but my guess is that the actuators were changed to match changes in the controlling circuitry, or that the supplier just had a better idea for producing them at a lower cost and substituted the new part in. However, I think those cases are just listed as superceded parts in the EPC, not unique parts per engine number.
I have a similar question about the vacuum pump on my '90 602 - the EPC (and Rusty's catalog) call for a different VP for this year, certain engine number range, and it's ~ $150 more than the pumps before and after it. Could I use the less expensive pump??? On Dec 30, 2007 8:27 PM, Kaleb C. Striplin <[EMAIL PROTECTED]> wrote: > Im sure nobody here knows, but thought i would ask anyway.

I cant see what difference there would be. -- OK Don, KD5NRO Norman, OK "There are three kinds of lies: lies, damn lies, and statistics." -Benjamin Disraeli and/or Mark Twain '90 300D, '87 300SDL, '81 240D, '78 450SLC, '97 Ply Grand Voyager _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
