Hello all,

2010 2.0 Tdi So this morning I've changed the rear boot lid old one rusty. everything going good that's all done checked HL break light number plate lights all ok. Rear wiper not working ok swapped with old one still not working checked fuses all ok went to turn ignition on nothing no lights so i'm gussing when I've checked fuses I've done something Immobilizer maybe? any Ideas please.

Everything was fine before I checked fuses all the lights came on etc. Problem started after I removed fuses to check none blown I'm quite sure all fuses are back in the correct positions.

How did you check fuses?

Check main ignition one again.

Check batter voltage and maybe remove terminal for a while and replace to reset everything.

Thanks for reply,

Fuses checked with continuity tester, I disconnected battery last night from the car and have had it on charge overnight.

About to go out and see if anything has come back to life and will also check fuses before connecting battery back up.

ok been out battery fully charged all fuses checked again got interior light car locks unlocks with key fob radio comes on but absolutely nothing else. Even put jump leads from another car just to check no difference its dead.

Fusible link on or near battery terminal

fusible link where would this be? what does it look like?

Normally close to the battery, and certainly under the bonnet. Google it for an image.

Have you checked ALL the fuses etc, inc under bonnet?

Modern fusible links are sort of 1cm x 1cm box like fuses in the engine bay fuse box. Where alot of the relays are.

Probably fairly high average. Maybe 30-50A.

Also, check that you have good contact on all the fuses you have mucked with. Maybe bent a blade connector over or something.

ok thanks again have checked all fuses including under the bonnet nothing appears to be wrong.

All fixed turns out it was a dodgy connection on the ignition barrel. many hrs of head scratching and going over and over things again and again, it's fired back into life. Thank you to BlueWagon for your info of things to check etc. Now next weekend I can carry on trying to find out why the rear wiper doesn't work the thing that started it all off, hopefully just a broken wire on the replacement tailgate fingers crossed.

Hi Andy, I have the exact same problem on my car (albeit a Golf 6 1.4 TSi, but should be similar electrically to an Octavia 2 (we have an Octavia 3 & 4 also).

It started when the alarm went off during a battery drain test. Afterwards, same as you had: no ignition, no instruments or info screen, but central locking, sidelights & interior lights work.

I have no power to the ignition switch on the 4-wire connector, but can't check the keyswitch solenoid wires as it's too cramped. Did you have power at the switch? This makes me think it's not the problem, but worth checking I guess...

Hi Rick, have you checked all your fuses? make sure none have blown. take a picture with them all in place before you remove any 1st. I had nothing at all at the switch my problem turned out to be a dodgy connection on the switch.

Hope you find and fix the problem good luck.

Thanks, I'll let u know...

Confession time. Checked the SB fuses against wiring diagram, noticed F6 was blank, but listed as covering the instrument cluster module. Put the 5A that was in F5 in F6 and bingo! All came back to life.

When I was removing fuses 1 x 1 to check a battery drain, I must've put F6 back in the F5 empty slot - what an idiot!

well done on finding the problem a nice easy fix in the end 👍that's why I said take a picture of the fuse box before taking any out then you can check easy.
