Intermittent fault with Indicators!

[Ady_E]

I searched the internet high and low. There were plenty of people offering the relay as long as I was willing to buy a thousand at a time! :s Easier just to swap out the Hazard Warning Light Switch. Mind you since giving the relay a tap with the handle end of a screwdriver, I haven't had any problems!

I think you're probably right. Even thought he nice folk at Omron sent one gratis, it may be less grief to spend £15/€30 on the full kit. I'll try the mechanical response first though, since a thump of the dashboard gets it going again.

Never had a problem since!

Hi, I had the same problem on my Golf IV TDI - indicators in both directions flashing erratically or stopping altogether. All bulbs checked & OK.
The fault lay within the Hazard Flasher Switch module in the dashboard, which developed dodgy switch contacts. You can either replace the unit yourself for about 18 quid, or dismantle and repair existing unit. My local VW main dealer wanted to charge 70 quid labour for fitting!! It takes about 5 minutes!! First prise out blank switch covers on both sides of the Hazard Switch for easier access, then squeeze in the two side clips and puill out the Hazard Switch module. Unplug.
Carefully unclip the button, then unclip the case and slide off.
You will see eight spring finger contacts, four on each side. First try cleaning these contacts with Switch Cleaner spray (maplin etc). Gently flex the relay assembly and look closely at the spring fingers to see if they are lifting off the flat contacts. Note that depending on the switch position (in or out) some contacts have a raised peice of plastic to deliberately lift and disconnect them. Check for undesired lifting when each contact should be down. If spring fingers are loose, carefully bend at fold with tweezers to increase force of spring contact. This need only take 10 mins or so, I cured two fairly slack contacts.
Before reassembling, check by plugging back into car wiring. Make sure L & R indicators AND hazards flash, beware hazards will only flash on one side if contacts still slack. Flex the relay assembly slightly to make sure intermittent behaviour is cured. Reassemble. Go spend the 18 quid you have saved on a meal out.

Hi,
Im new here and was reading this topic and thought that maybe someone could tell me if the stuff in the thread could apply to my car?
its a VW polo 05 Reg,
i noticed a while ago that i heard a clicking noise every so often that sounded like my indicators but there was no light on my dash,
then on one occassion i'd turned my car on and gone to open the gates at the end of my drive and when i turned round i noticed that the indicators (side ones) had flashed, i still hear the tick even though no one else has and yesterday when it happened i was reversing off the in-laws drive and i asked them if anything happened as it happened and they said all my indicators at the front of my car had flashed!!, i'd not touched anything and nothing showed on the dash, so after months my other half now belives me..... any ideas if this is connected to the topic of this thread?
thanks
Carrie.

I think BMW must use the same switch unit. They seem to have really bad problems with intermittently working indicators. At least in my experience!

Thankyou guys for your thourough information and diagrams/pics. My wifes Allroad has the same problem and I thought it would be and expensive LITTLE problem. But thanks to this forum it looks pretty simple.

Hey similar problems here, except my lights flicker quickly on indicator when I remove the fuse and stay permamnently iluminated when the fuse is back in place? Is this a relay problem?
