Hey guys,

I'm having trouble with my Skoda Octavia 1.8L 20v SLX..

The problem is as follows..

when i turn the ignition and start it, it fires and the engine starts but just after when it starts in dies and the lamp that has a "Car and a key symbol flashes in intervals".. it worked the night before but now it just wont work properly.. What could it be?

Its sounds like an immobilser issue, try your spare key

Thats always the reply I get with that

Yeah sounds like the key isn't communicating with the ECU. Do a search on the forum there have been other people who've had this happen.

Hahahaha xD So am i screwed or is it anyway to hardwire it or just anything? Could it be the alarm?..

It could be the reader coil or the loom to the dash insert.

Yes after searching this morning after a solution i found that post and i've already taken it apart but i don't know how to check if it's bad.. can i to it through my multimeter device by checking continuity? Or what to look for?

Make sure you don't have a second car key on the same keyring

Yes, it only has one key and one leather bit with the retailer who sold it with no key in it :p

I meant a key for a second car other than the Octavia

if you have another car and keep its key on the same keyring.

To check the loom you need to remove the 'b' connector (the green one) from the back of the dash. The black wire goes to pin 17 and the green wire goes to pin 2. IIRC, the resistance of the coil is about 20ohm.

Oh ok, no i dont :p

Ok Is it hard to open the b connector? i tried to figure it out but.. yeah :p

If it has a pink lever on it, then lift it up whilst sliding the connector out.

No no getting it out i've figured out but opening it so i can remove the wires :p

Slide the pink end off the connector and the green part slides off the end.

Oh ok Gonna make a reading tommorow

Can't get a good reading but 17-18ish is what i get.. i'm gonna buy a new cable. the pin 2 was moving to much so i guess that when you put it into the panel it just falls back an wont connect good enough :p

Tried to check the cable and also to take it out of the green connector but it still doesn't recognize the key..

PROBLEM SOLVED!!

The little RFID chip jumped out when i changed batteries last night, didnt know what it was so i put it in a bowl.. later i saw the link below.

Then i noticed that mine was the same and checked for a spot in the key for it.. BINGO! now it works thanks for the fast replies etc etc.
