Hello I'm new one here, my dad has just bought himself a Laurin & Klement Superb. 

Anyhow I tried to plug my diagnostic reader in tonight just out of interest, however it would not power up🤔. It has keyless entry so I was wondering if there is a procedure for where to put the key before the diagnostic port would power up. 

Any help would be appreciated

(Btw it is a maxidiag which I have used on many car including other Skoda's)

Ignition has to be on before diagnostics will work.

Tried with ignition on and still have no luck. 

 

Ok. Does it work when the engine is running? If not you could check fuse 13 - it supplies power to the diagnostic socket.

 

 

It's also possible that your diagnostic tool is not compatible with the car. Has it worked on other VAG models of a similar age?

I will check the fuse, yeah it works on my 14 A6 and my father in law's A4.
