my allroad was a tip and after long highway drives it was slow to react in the city (or vice verca) - then a friend told me about the 'turn key to on, depress gas pedal for 15 seconds, turn key off' trick that reset the tip's computer (and probably a few others).

(since my b7 was a manual it wasn't an issue)

is there a similar trick for the b8?

thanks,
nick
