Engine Misfire

Can I please have the exact code numbers not code descriptions?You could have a vacuum leak.

The codes are as follows: 16517, 16684, 16685, 16686, 16687, 17526, 17705.

There should be a letter followed by a four digit code for the trouble codes?

My reader is only giving me the number codes.

What kind of reader do you have?

Even the factory scan tool shows the letter followed by the four digit code.

Its a reader specifically for VW and Audi

You have misfires for cylinder 1 2 and 3 also you also have a slow response bank 1 sensor one slow response usually a lazy o2 sensor.You also have a bank 1 sensor 2 heater o2 sensor heater circuit you could have a bad heater element in that o2 sensor.The 17705 is throttle valve connection pressure loss.I would check all the turbo hoses and connections.As far as the misfires that are only at idle?I would be looking for a vacuum leak.Even the Vw factory vas laptop scan has the numbers like yours but right next to that it shows the ob2 code number the letter followed by the four digit number.That's crazy yours doesn't.

I just saw the misfire codes set with the 17705 they smoke tested and found the intake boot under the intake manifold was rotting and leaking.
