I have removed it to fit chrome rings ,**** I wish l hadn't .Fitted back ok then went to start , it did momentarily then stopped with the chuffing key symbol showing.!!Panic Mr Manwaring .Also now warning siren goes off ****.Please don't tell me it's a dealer job.

Removed what mate? We need a bit more detail about what you've done!

Sorry Ray Luxury -Yacht l had removed the dashboard /instrument binnacle ,on top of this I'm in (discussion)with the eBay seller who sold me the chrome rings without adhesive ,initially saying they clip fit ,no sign of how,no instructions,is now directing me to a Bison adhesive site !Time to ask for a refund me thinks.Rant over!

I assume you didn't disconnect the battery before you removed the instrument cluster?

No pauldazzle battery left connected

Have had to leave windows down and sunroof open as can't shut,but central locking works checking with both keys!

Reverse steps you took. Check for any loose wiring or trapped/cut wires or better yet disconnected wires. If in doubt, post a pic, it helps.

 

I don't know if the mkI Octy has anything clever to detect tamper. It could just be a cruel and very random in a billion fault that's occurring at the same time.

Sounds like you have lost they key programming somehow or not plugged in the dash correctly.

Thanks for replies,ColinD and Tech1e ,l took great care reconnecting the two connectors,although the right hand plug is not easy due to limited loom length.Guss what .its now raining.must be a bad old lad.

I have removed cluster few times and battery was connected every time and never had issues. Check if connectors fit housing correctly, that is probably the issue!

Arminator l can't see how you can misalign the plugs they are of a very sorted design with the locking tab system that ensures correct connection.

I mentioned this because may be some of the pins went wrong. to be more precise: Pin number 2 on Green 32-pin Connector is for reading coil for immobilizer 1 (from 05.99 prod.), and  pin number 17 reading coil for immobilizer 2 (from 05.99 prod.). might be worth checking.

Thanks for the info Arminator will disconnect and check it out visually ,cheers.

Keys have lost communication with the immobiliser which is why you have flashing key symbol, & the engine shuts down after a few seconds.

You should always disconnect the battery when when working on the cluster to avoid problems like this. Might be worth disconnecting the battery, & re-seating the cluster connectors.

Have a read. https://forums.tdiclub.com/showthread.php?t=271900

Thanks pauldazzle,l did voice concern on my chrome dial rings and multi function rectangle post but was assured it was ok to disconnect/ reconnect without battery disconnection.l'll study the two American sites you've guided me to.Brilliant.

Sorry forgot pretty all ok to me

connector seems fine. did you get a sticker with scratch able part that comes with you spare key? this sticker contains 4-letter pin code you can use for pairing your keys with cluster using vcds.

Unfortunately all l got on purchase was two keys.

unfortunately  you will have to look for someone who has a VAG tacho to pair keys with the cluster...

Hey!! She's running after giving the green socket/connection a lot of sweat and after many warning lights appearing I'm left with the seat belt and low brake fluid lights on. I'm just off on a quick test run ,not far down our lane.

Went ok except brake fluid went out then came back on when did a test restart ,by the way the seat belt light was the airbag light ,my mistake.l have lost faith in the socket connection after this episode,as l thought that it was a 'sorted' design.ls it a case of Father Time?

You'll have fault codes which will need to be cleared before the warning lights will go out.

so at the end it was connector-fault? happy that you have solved it!

Yes Arminator ,reluctant as I was but the flexing of the plug partially solved the problem .l'm now left wth the airbag light on continuously , but does momentarily go out on start up .Hopefully my stepson will be able to extinguish on his Vag com/VCDS as mentioned by pauldazzle.Thanks very much to all you guys who responded to my plight.Cheers Vince
