Just joined the site... Thanks for your help in advance.
My mechanic hooked up the computer reader and nothing was wrong. Misfiring is becoming more and more frequent any reason is this ignition related? He said they was 5-6 ignition coils?
Any help would be appreciated... 82K and it works well just this...

 

I would imagine this is a front wheel drive correct? (non quattro)
You most likely have a bad CVT transmission, there are several complaints and related repair TSB's at the dealer for this, and the outcome im sorry to say is quite expensive.
