OBD Adapters & Software: Find Yours Now!

Hello everyone, here's another new one.

Currently, I'm having problems with my 80 TDI. I want to build my own diagnostic adapter. Does anyone have experience with DIY builds? Which adapter should I assemble, and what software is suitable? I would prefer free software. If there's nothing good available for free, I'll probably have to buy VAG COM, or?

Thank you very much.

Igor.

Hi Igor,

Please enter "Adapter" in the search function.

Find something in the adapter-related article (folder "Tips & Tricks") on Rainer's website.
Maik's version is easier to handle, while mine offers more stable communication under worst-case conditions and better protection against damage to the PC and car.
(However, according to the datasheet, pins C5, C10, C12, and C13 in Maik's adapter should only be 1µF each for the MAX232.)

Auto-Intern and(?) DRV Berlin offer VAGCOM as free, limited versions for download, which allow you to handle most common tasks.
For VAG cars, I find VAGCOM to be the optimal solution.

Hi,

My car still has an OBD connector. Where can I get these things?
