What's this tic-toc from behind the dash?
I have an '02 Passat wagon, 1.8T and AT.
A few weeks ago I noticed a muted "tic-toc" sound coming from behind the dash, repeating at an interval of about 5 seconds or so. I noticed it first on driving down the alley and navigating the local streets. After a few minutes and on the freeway, I'd only hear the sound when the engine was under load, not when coasting or idling at a stop. After about 20 minutes or so, it would stop altogether, although on longer drives it will start up again for a few minutes and stop again. There are no starting or driveability issues and gas mileage is as expected for the temperature. Any idea what I'm hearing? -- Bert Hyman St. Paul, MN |

I swear it winds up a timer of some sort ... lol... strange thing, but consistently there when I'm using the wipers. And no correlation between the frequency of wiper delay and the tick/tock sound, but always present when they're on. Wes |

Do you lose the clock settings?

Whoever the OP is! ;-)
Trying to see if the cluster loses power or ground which might reset the clock and might cause the tic-toc sound. I have heard ticking before from some Passats if a fuse has blown affecting the instrument cluster. Or maybe even if the battery is old or charging system is not normal.

One random thought - my wife who is a very good driver but almost oblivious to what her car (2001 Saab 9-5 wagon) is telling her at that moment once complained about such a tic-toc to me. A REMARKABLE event that she should notice at all. Turned out to be her rear-wiper delay as Willy suggested. But the center-nut on her wipers had come loose so there was no corresponding movement of the wiper to alert her. Non-latching relays will also tic or toc if the voltage they see is intermittent or too low - as dave suggests. And if your car is equipped with DRL and auto-dimmers on the headlights, that will do it during the day if the lights are accidentally left ON and on HIGH BEAM - which will give no overt evidence to the driver other than the blue indicator on the dash - easily overlooked by day.

Based on the perceived behavior, constant during initial warmup, then only under load, then stopping altogether, makes me think it's some emissions-related device doing something. It didn't do it at all today. Maybe the few days of 50+F temperatures has the car feeling better. -- Bert Hyman St. Paul, MN |

What frequency did they operate at? Well, in the case of my 09 TDI, let me try to better describe what I hear. This is a consistent occurrence, and everything seems to be working normally. When the wipers are on, in delayed mode, I hear a sound that goes something like this... "tick, followed by what I would best describe as a very hard to hear but what sounds like electric sparking for about 5 seconds, then a tock"... You know the sounds you hear if you touch to wires together... that arcing sound. Or another way to describe it would be, if you were able to continuously wind up a clock until it's fully wound, it sounds like that. So it's tick, then winding / sparking, then tock. I actually timed it one day, and don't remember the exact intervals, but they were consistent, and there seems to be no correlation with whether the wipers are on a long or short delay. And then there's the ticking that occurs in cold weather when you're idling and what I believe to be the electric accessory heater kicking on and off... but doesn't do that often once you're moving. Must be because of the lower RPM'S.... that's another sound all together. Maybe my ears are just too good! LOL Wes |
