the car runs but idles ****e i dunno what to do crap it lol 

Cracked wire somewhere?

given the number of "Short To Ground" messages..

clive said earthing issue 

Id trust his answer ahead of mine

Deffo an earth issue

Last time I saw this set of faults, it was a melted fuseholder on the battery. All the items listed are fed from terminal 87F. If it is an earth fault, the most like candidate would be the earth point in the plenum chamber. IIRC, it could also be a relay.

Isn't that the fuel pump relay list ??

As in a knackered relay

Yes, 87F (the small terminal on the relay plate) is fed via the fuel pump relay.

hmmm so get a new relay then

Sorry to drag up an old thread... 

Ive a very similar bunch of codes come up with my eml yesterday. same 11 really plus a few more

just wondering if the cause was that fuel pump relay mentioned and did a new one sort it?

tried to PM the OP but message box full i think so hoping he'll catch it here

Sounds like the relay too me.

any pointers as to where id find this relay?

Ill give it a google anyway

thanks

Here you go - http://workshop-manuals.com/skoda/octavia-mk1/drive_unit/1.8_ltr./92_kw_engine_fuel_injection_and_ignition_system_motronic/mixture_preparation_system_electronic_inj.gas/testing_components_and_functions_ii/test_fuel_pump_relay_and_control/

 

Should be marked 409 on the top

409 that's the one.

Under the dash. Real easy to find and swap.

Brace yourself for the price bomb ....

 

 

About £70 IIRC

WHAT!! i just read on a vw forum they were a tenner lol

thats sterling too damn. next time im at the breakers im gonna grab a bunch of them. really wasnt expecting that though

I'm sure when I asked in TPS they were around that much, they seem to be £10 on ebay second hand, might be worth trying someone breaking on here.

Some cheap ones on eBay allright.

Bit late in the day for this but if I'm unscrewing the relay plate should I disconnect the negative on the battery first?

Why are you unscrewing, just drop down the plastic under dash cover thing and pull out the relay.

I have problem with water in drivers door and corroded wires in the connector. I also noticed water sitting in the rubber grommet that protects the wires going between the door and car. figured if water in there in cause easily be running down the wires in under the facia.

Im not sure but if those wires run into that plate I thought unscrewing and inspecting might be an idea

Ah right got you, thought you were making life hard for yourself there lol.

 

That could be the cause of the codes for you right there

Yep was thinking the very same:) probably safest to disconnect the negative I guess. Electricity scares the bejeebees outta me. I hate doing anything around the house involves wiring. A lot less volts/current in the car but still don't fancied gettin zapped

My buddy has a 07 1.9TDi octavia. would it have the same fuel pump relay to swap into mine to check if mine faulty?

popped my one out (says 409 on top) and certainly doesnt look cruddy or melted or damaged anyway
