You have to be quite careful with this - the ID number says what it is descriptively but the wiring diagram will not know the subtle differences such as round plug / square plug or which exact part number.


Mercedes are very good at documentation - the only way to get exactly the correct part (as when it left the factory) is to use EPC

Don't leave that there - I'll take it to bits!

So how do I connect the dots between, say, the part that shows up in a fault code...like my K75 relay...and the EPC?

This is a weakness in the Mercedes system. The wiring diagram and EPC don’t really cross reference. You need to identify the part in EPC from its verbal description on the schematic. EPC is the only PN source, other than what’s printed on the old part.

Were can I get EPC for my 85sd's?

For the most recent part numbers (a few change and get replaced - most don't) you need to get a subscription via www.startekinfo.com


It used to be free in the US of A - but I understand you guys now have to pay too.


Otherwise there is ebay where people sell pirated downloaded versions - I've never bought one so I can't tell if they are good, reliable, or even safe


Another alternative is to look out for parts books - they do exist - fairly rare but have period correct numbers for the cars when they were released. Like I said some of the parts in these books will have been updated with different numbers - but it is something that if you were to go to the dealer with they'd be able to tell you the latest number.


In principle I think the best alternative is to make friends with your local MB parts counter and ask them to quote for what ever you need. Despite what many people the dealer isn't always that bad - OK sometimes they are silly dreadful - but I think you might be surprised how often Febi junk is more expensive than the dealer part...

...final option - join an official Mercedes club - you can then get "free" access to EPC so long as you pay your club subscription.

Thanks Stretch! In the past 9 years have tried twice on eBay, once a CD & download both were a bust.
