Golf Mk IV - Spurious indicator clicking - 547HEW
Vehicle is 150,000 miles 5 dr 1.9 TDI PD 2001MY

Driving to work this morning, the indicator "clicker" kept on clicking after the direction indicator switch had been returned to its central off position.

The extra clicks are in a sort of random sequence, and do not appear to be lighting up the external flasher lamps. The dash panel arrows are not being lit either.

Conditions were damp, and headlights on.

The extra clicks eventally subside, until the next indication of directiion change is made. Seems to be very repeatable.

I should point out that I do use the indicators a lot, so could have worn something out? (I've owned the vehcile from new)

Any suggestions very welcome

My daughter's Lupo started doing this intermittantly; apparantly it got worse until it one day, on the motorway, smoke started coming from the steering column! One new hazard switch/indicator relay (combined on Lupo) + indicator stalk unit + some expensive VAG labour later and it was sorted. From her experince (and of mine, having to pay for it) I'd suggest you get it sorted sooner than later...

Replaced Hazard light switch with new part, 1J0 953 235 J 01C.

In first indication of next drive, gave one extra "click", then multiple "Clicks" during this drive (70m length).

At least this Switch Unit gives a quieter click, so is less obtrusive!

Clicks are sometimes generated follwing use of indicators, and sometimes completely at random. Vehicle moving, and key on, engine not running.

My theory is that the unit is picking up spikes which activate the audio transducer only

Only VAGCOM DTC's set are:

P1264? (from memory) ECT sensor - intermittent short to ground, or to plus, which has reappeared since cleared, but did appear 30 to 50,000 miles ago without any symptoms.

Front loudspeaker - intermittent (not notcied any crackles - think this was from when I changed window winder regulator)

I will change the ECT sensor next.

New ECT sensor fitted (059919501A)

No fault codes now, but problem persists.

Any suggestions welcome.

I note JohnM's post where similar concern reported, and indicator stalk also changed - I am not favouring indicator stalk as root cause, since use of this control gives perfect intended indication, but would welcome any hypothesis which does!

Low cost interim repair seems to have fixed it. Dirty indicator stalk switch. On advice from Electrical Engineer colleague, rapidly swept stalk up and down many times with igintion off. Did this for about 30secs a few weeks ago and not a spurious click since. Humble pie re JohnM's suggestion!

Glad to hear you got it fixed - I (and the garages) also assumed that the hazard switch was the problem and that the indicator switch burnt out as a result...
