Hi all.

 

Octavia 2013 2.0 TDi Auto

 

The car was stood for almost two years before I got it and was full of damp/condensation, dripping in some places. I've dried an cleaned it up and it's been running perfectly for a few months with the exception of the radio turning on/off randomly.

 

As the only things I hadn't checked were the footwell multi-plugs behind the trim, last weekend I took out and put back all the fuses in the passenger compartment and disconnected/re-connected the multi-plugs in the footwell. All were clean and not showing signs of green build-up or corrosion.

 

Now I have no lights on the dash at all when I put the key in and turn it - except for the normal warning pictures if a door/bonnet/boot is open. The remote lock/open off the fob still works, as does the radio and interior lights.

 

I've re-checked to see if I'd bent any pins in the connectors and re-tested each fuse with a small bulb across a separate battery - all ok.

 

I've also checked all fuses in the engine compartment.

 

I tried an ODBC reader but after entering the VIN manually as it wouldn't pick it up from the ECU it just told me it couldn't see anything to talk to.

 

When I was doing the work the battery was still connected.

 

My guess is I've wrecked the ECU but does anyone have any other ideas I can try before getting it towed for a full check at Skoda?

 

Many thanks,

 

Steve

 

I would have a chat with my local taxi drivers (they all drive Skodas) and see if they can point you in the direction of  a good independent locally to you 1st

You could try disconnecting the battery for a while and see if anything resets its self when reconnected.

If it's anything like my VCDS the ignition needs to be switched on for it to communicate with the ECU.

Thanks for replies, all.

 

Ords, I've tried the disconnection for 24 hours but no luck.

Gammyleg, I can't get any ignition to begin with, no lights on the dash at all.

 

Hopefully I'll have a wiring diagram tonight and take it from there.
