Scrape

Just had this for the second time on my 6 year old octy - the last time was about 3 years ago

Interesting, we have this and the only issue other that we have is to do the cam belt and pump because i forgot to get this concession from the dealer.

cheers for the reply was just making sure that was the correct thing to do ,

I get mine on cold damp days (such as this morning) always go with a restart though. Dodgy connection give it a clean should solve it. If you do a search there is something you can used which is meant to stop it some sort of lube...........but off the top of my head I cant remember what its called.

The sensor prongs cannot be got at in later expansion tanks, If you can't see them with the cap off, new bottle required. Only £14

had this on an octavia and the wifes fabia VRS,

replacing the temp sensor in the thermostat housing is the fix
