hi, my 2005 Octavia 2.0tdi (117000miles) is slow to start when engine is hot, perfect when cold. it has also developed rough idle (again only when engine hot)

any ideas would be appreciated

thanks

Oscar

sorry forgot to add

drives perfect & smooth, and doesn't  appear to have any noise from flywheel area

Could be camshaft sensor

Try getting car scanned with VCDS

thanks Mike

 

as with you I can live with the slow starting ok, but I am just getting concerned about the rough idle

I will get battery checked 1st

 

then as suggested by other member, get it scanned with VCDS

Low cranking speed when hot ? On the 2.0 tdi the injector wiring requires disconnecting then crank it over when it's hot and read the cranking speed. Can't remember exact figure but think it's something like a minimum of 250 to 300 rpm. If yours reads low suspect starter motor or battery. You will not get a code for this btw.

thanks FLAPPERJACK7

will give it a try

I had the Hot Start issue on my 1.9 tdi Octavia. I've had a "Software" update at Shark Performance and touch wood it's cured it !
