      16711 - P0327 - Knock Sensor 1 Circ Low Input

      I went on a recent road trip, and filled up on some shady gas. Immediately the MIL tripped but I didn't have my vagcom on me. Once I used the crappy gas, I filled again with some V-power and the MIL went out, only to come back after the next refill.

      A day later I got the car home and scanned -

      16711 - P0327 - Knock Sensor 1 Circ Low Input - Intermittent

      Does this mean the car actually knocked, probably due to the crap gas? Or is this an indication of sensor malfunction? Which knock sensor is Circuit 1, and where is it located?

      Will I need a multi-meter to diagnose?

      knock sensor 1 (G61) located on the timing belt side of the engine according to the bentley. i have this same dtc. the bolt that holds in the knock sensor needs to be tightened to 20Nm = 14.75ft-lb in order for the sensor to work properly. was recommended that i first make sure its torqued correctly before doing anything else.

      retorqued the bolts but still get the intermittent dtc... not sure where to go from there

      I still think it was bad fuel, which is listed as one possible cause.

      The MIL came up both times I filled in Wyoming, but as soon as I got a good tank of Vpower in it near the track, it went out.

      I cleared the codes yesterday and I'll drive her for a bit to see if it trips again.

      like i said i have the same code. it wont create a CEL everytime though. really need a vagcom to clear it and see if it comes back quickly. it will be logged in vagcom whenever it happens but has to happen repeatedly within a certian time (dont recall how often) to throw a CEL.

      word, well my MIL came back on today after I cleared with vagcom, but I still have about 1/8 tank of the questionable wyoming gas in here . . . I'll fill it up, clear, and post back

      knock sensor low code again . . .

      I just filled with some 91 vpower from my usual shell station and cleared my codes. I hope i doesn't come back.

      crappy wyoming gas ugh . . .
