I have developed a problem on the above van, van fuel gauge behaves erractically and also my speedo at the same time, there is a clicking noise coming from right hand side between the door and steering wheel when this happens as if its behind the panel on the console. any ideas what this is would be very much appreciated thank you

Hello melville1967,
Firstly, I need to confess that I am no expert on the matter so had to resolve in old fashioned Internet searching.
I found a page that is saying it could be a bad sending unit inside the tank itself. Something to do with the resistance of the potentiometer inside is broke on the half tank part which will need replacing.
However, you are also saying the speedo is a little erratic. So I am not entirely sure if there is a separate problem with the speedometer of if it is one issue causing two problems.
 
The clicking noise from the cabin fusebox area sounds like it could be a relay.. Whether that's the cause of, or another side effect of your problem, I don't know.
 
Sounds like it to me too.

Has the OP tried swapping a few relays around and seeing what happens? You should be able to feel the one thats clicking while the problem occurs. Once you do that, and have another on the board thats the same, swap them and see if the problem moves / goes away.
 
sorry for the delay swapped the relay but still the same it clicks and the fuel gauge behaves erractically when it does also when i connect my bike rack only the right indicator works on the rack??
 
I don't suppose these faults have arrived since a towbar has been fitted or the bike rack has been added has it ?
 
nope the towbar was already fitted and it already started clicking before i even got the back rack,it does not do it all the time. when i connnect the towbar mounted bike rack the right hand indicator works but not the left hand same when i try the hazards on the bike rack, but the indicators on the van work ok all of them ?
 
forgot to mention when the above happens my fuel gauge behaves erratically too!
 
This is a common fault with Skoda Octavia the "ignition" relay suffers dry joints might be worth checking the relay cabinet under the bonnet by the battery.
