Well the local dealer let me down. Called first, parts guy took forever to look it up and then told me it was a 30 amp fuse. I was already in my car after work and so I decided to make the trip to see if I could look over his shoulder to help look up the part number, and wasted an hour. Used the PC in their customer lobby to reach the on-line EPC and found the part number for the 80 amp strip fuse; parts guy plugged that into their inventory and... they don't stock it! Special order, $4+, come back in a couple days. I thanked him for his time and declined to purchase the 30 amp fuse for $4 that according to the shop foreman was the right fuse. Guess I'll have to order it on-line.
The odd part is that I couldn't find the part number using my 124 wagon VIN, so I searched in the EPC using 123.133. In 1987, were there different versions of glow plug relays used (fused and then later internal breaker)? Is this another "feature" of the EPC? Do I need to go back to EPC school? -Max -----Original Message----- From: mercedes-boun...@okiebenz.com [mailto:mercedes-boun...@okiebenz.com] On Behalf Of Rich Thomas Sent: Monday, February 01, 2010 5:56 PM To: Mercedes Discussion List Subject: Re: [MBZ] One bad glow plug spoils the whole bunch? The fuses are actually fairly cheap at the dealer, or were at the Houston dealer a couple of years ago (after I explained to the guy what they were). --R Dillon, Meade M CIV SPAWARSYSCEN-ATLANTIC, 53310 wrote: > Rich, our cars must have been plotting.
