Dear All,

When I turn ON the parking lights, the left indicator lights (front and rear) are also ON. I checked all the fuses and they are correct and not blown away.

Also during the night I cannot use left indicator as they are always ON and do not blink.

Only when I turn OFF the parking lights, and turn on the left indicator, they work and blink properly.

Also there is another problem associated with parking lights i.e., while using the left indicators, the parking lights also blink along with indicators.

Please suggest.

Regards,

check the earthing on the lights

How to check ?

How to check ?

Take it to a garage.

How to check ?

First check the connections at the lamp, clean if required.

Follow the cables from the lights, at some point a brown cable will earth to the car body. Check that connection.

Have you fitted any new bulbs recently?

Thanks for the input.

I've not fitted any new bulbs. I've check the brown cable from the indicator to the car ground (located in the boot space (back side), both are intact.

Any way to test whether grounding is proper or not? using multimeter???

Either take the ground off and check it, or turn the lamp on and see if there's a voltage between the ground point and the car body.

Have you checked the connectors at the lamp?

Had a problem a few years back with lights and indicators on a Rover 200, turned out to be water getting in one of the rear light clusters and causing a short circuit.

Other than that the indicator arm unit could have developed a fault, had that one before as well.

The connector is in good condition and no signs of rust or dust.

I also forgot to mention this ... " When I turn ON the head lights, there is no symbol on the display to show high beam or low beam, even if I switch between low and high beam.

I'm going to measure the voltage now....

cheap,or expensive multimeters are useful ,but misleading when checking car ground connections. You can get a reading of 'o' ohms if you connect your meter between the + 12 volt side of a bulb ,and the car ground!. This is because the resistance of a bulb when cold is under 1 ohm. You can remove the bulb and check you have a ground connection ,and that + 12 volts is going to the bulb. The fact that the meter takes a few milliamps when reading ohms, and a bulb takes amps,doesnt really show that the wiring and holder can pass 'amps' correctly. To sum up a bulb with leads attached is a better bet for fault finding. You can temporarily connect a wire from a good ground (under a bolt already in use in the car) to the lampholders ground (NOT the 12 volt,+ve side !) ,the fault may go,or the bulb will increase brightness,will indicate a poor earth on this lampholder.

You are true, with multimeter it is always showing 0 reading between ground point and the body of the car. I'll have to get the bulb setup ready to check the ground.

May i know why high beam and low beam symbol disappear?

I've a half an idea about the warning lights. Do you get the front (if applicable) and rear fog light warning lamps working correctly?

Only Front fog lamps can be switched ON but rear fog lamps (though lamps are correct) but not working when actuated by the switch (Lamp switch)

I forgot to add, the fog lamp (rear and front) symbols appear on the display on the low beam and high beam does not appear.

[brain sizzles in total confusion]

To summarize and not confuse, here is the set of problems with my octavia-I 1.9TDI Rider:

1. Left indicators (front and rear) are ON when parking lights are ON. When parking lights are off, turning ON the left indicator causes all the parking ligts to blink along with Left indicators (front and rear) but no problem with right indicators.

2. Low beam and high beam symbol on the display is not appearing.

3. Both (front and rear) Fog lights symbols appear but rear fog lights in OFF state (lamps are intact and not blown away) switched both are turned ON via knob (pull out twice gently)

The low beam and high beam symbol is appearing on the display, I'd a fuse overhaul and the low beam fuse was blown away.

Dear Team,

Please give your inputs, am still not able to resolve the indicator and parking light problem .

Hence my suggestion to measure voltage drop between the lamp ground and the body with the lamp on- the current through the bulb should generate hardly any drop on a good connection, but several volts on a duffer.

It's good advice though. Multimeters are designed to have a high resistance- the higher the better- so you can get misleading results if you don't know how to use them.

It is possible to get a high resistance between the bulb contact ,and the contact in the holder.The reading taken on a voltmeter between this contact ,and a good ground would show a misleading small amount, interpreted as not being the fault, therefore this is not the best way to fault find in this case. I would still prefer to use a 21 watt,12 volt bulb ,on leads. The bulb when connected to 12 volts shows full brilliance. Any poor earths ,and the bulb will be dimmer .1.8 amps flows in the circuit ,not a few milliamps,as when using a meter.

Dear Team,

Today I inspected the electrical wiring starting from FUSE box and found the parking and turn indicator wires are short and suspect the wiring below the dashboard could have been shorted. So far no harm in driving.

But unknowningly my local electrician unplugged the odometer wire from back side and after that airbag warning comes and I do not know how to disable the same. Also I do not have VAG COM. should I've to take to service station to clear the error codes/warnings?

Please advice. Also if any of you have wiring diagram for skoda octavia that will be of great help in resolving the shortcircuit within the dashboard.
