Thanks everyone , I will get to the bottom of this and report back

Hi Pls clarify what a cycling relay is ( I know what a relay is ) Thanks For draining batteries or making noises ? Ta

Annoying battery drain killing car after just a few days unused New battery so not the battery One thing I am getting when car is turned off is a relay type noise (almost fizing noise) from under the bonnet As you look under the bonnet at the back right hand side it appears to be from under the plastic trims very close to the screen No idea what electrics are under there ? I have original satnav / stereo , no dash cams etc but any clues to look for would be helpful Thanks

I have exactly the same problem , 12 plate Superb 2.0 tdi , battery new and won't last more than 3 days , currently having to disconnect battery if not using the car for a few days

Just a follow up to this issue When tank was fairly low on fuel i accessed the fuel pump and float sender in the tank I exercised the gloat sender back and forwards with my hand Put it all back together and so far guage is now reading correct Filled the car up and so far the needle now shows full correctly So looks like the issue is a dodgy in tank sender Will see how I get on now

Yep Currently I fill up and use the trip as a guide to how much range / fuel I have left

Thanks for comments I personally am beginning to think that my fuel guage issue is now either a varying resistance issue either through corroded contact or the float resistor mechanism failing / sticking Yesterday the fuel guage was on red , today it reads different and more correct at below half tank I think inspecting the tank will now be necessary as its clearly not just adjustment Can't wait, not

Thanks for resistance readings , I will measure A few youtube searches show vcds has the option to adapt / calibrate fuel guage readings Ta

Pls could you tell me what VCDS cable / system you use ? What sort of price ? Ta

Thanks for comments My guage is well out With a 60 litre tank I can brim it till I see fuel ,it never goes above 3/4 then after about 250 miles , I hit fuel light I know from refilling about 25 / 30 litres Istill have lots of fuel left Car should easily do 400 miles around town So possibly I could adjust on VCDS ? That's interesting

Skoda Superb 2012 2.0 tdi Anyone got any info on what the fuel sender resistance readings at reserve & full should be ? My fuel guage only reads 3/4 full when brimmed and it then shows empty / fuel light on when clearly there is lots of fuel left Thought I would start by checking Ohms readings before pulling it all apart Also just out of interest can vagcom or whatever software adjust the fuel guage to suit my resistance readings ? Thanks

I spoke with Skoda parts quoting car info for a price on new EGR ( £340 plus vat ) They confirmed there is a vacuum solenoid which does something to the EGR, about £45 plus vat I note your comments re Engine Code , I also agree to a degree about EGR cleaners and injector cleaners in the fuel tank The only real way to clean an EGR is strip / soak and clean it It would be interesting to fully understand how the EGR opens , when / how long / what temperature / stays open / open & closes / how frequent Anyway, my emulator delete arrives in post today, so if my EGR continues to play up in the future I can fit it

Hi By engine code I mean fault code as in post above P0403 = EGR circuit fault Strangely enough I have done 2 long journeys and all OK at present I have purchased an emulator EGR delete and will keep this in reserve , at present I am running fuel cleaner in the tank now and will also try an EGR spray cleaner for what it's worth If EGR completely fails I can then delete it , however the car is running so well and never showed any physical signs of hesitation / poor idle etc that I will carry on as I am at present and see how things go

Code in post P0403 Yes it has a vacuum solenoid One part of the EGR is motor operated , there is also a other part vacuum operated
