I use a offline version of epc + wis, search in ebay. Has all vehicles including your 129.
If you can't find it let me know I think I can make a copy.

I thought that these did not exist.
But I happen to come across this downloadable manual for less then 27 dollar:
manual
Is it real?
Anybody bought this yet?

It is absolutely Rubbish!! I did purchase it 1-2 years ago. downloaded it and it was absolutely useless!! Had to get pay pal involved to get my money back.

 

I sure miss the nice printed manuals you used to get....I went though a lot of stuff and agree that company's products are rubbish...I forget the problem I had with them - I had paid - but decided "never again".

I settled on a subscription to Alldata. It's not perfect but the best I have seen. IMO.

Hello wlb50,
Did you mean these?

 

I have been using an ebay WIS/EPC sold by garive_5 for the last few months. Download and installation is a bit cumbersome (8 dvds worth of files), but the seller did provide decent technical support, which is essential. Every now and then it refuses to start due to some kind of error and I re-install the virtual machine (the VM portion only, no need to do a complete extraction and re-installation of the data files) and it works again for a while. I also have to start from the VM desktop icon, instead of the Mercedes.vbox file the instructions say to use. So it is a bit buggy, but can't complain for $8. The content itself is not as useful as I would want it to be and the search function always returns a great deal of unnecessary documents I have to open and scan to find what I'm looking for, wasting a great deal of time. I'm used to the Haynes books and paper service manuals from other automakers which are generally to the point, detailed, and comprehensive. Don't expect the same from the WIS, but it is definitely worth having. If anything, dealing with the inefficiency and frustration of the WIS prepares you for work on the car.

 

What does "WIS" stand for and did you find a good online manual for Mercedes Benz?

 

WIS = Workshop Information System.

There is no good online manual for our R129s. I, like many others, have bought the WIS and EPC (Electronic Parts Catalog) from one of the many eBay sellers.

Thank you for the information!! I would like to have a Mercedes Benz shop manual for my three Mercedes Benz. Do you have a suggestion on where to purchase an official Mercedes Benz shop manual?

 

EBay

 

I will check eBay. Thanks

 

Try an internet search?
I don't have anything else for you, sorry.
