Vag-Com Tunning for the Audi TDI


Registered User
Audi 1.9 TDI C5 1998 SE UK.

Just got my new Hex Vag-Com dongle thingamabob from Cister Automotive Design, Plugged it in, WORKS a treat!

Now how on earth do I know what numbers to type in to sort out my Diesel timing and increase the boost pressure just a little?

A little guidance from anyone in the know would be appreciated
