I was looking over my engine bay today and I found a small leak on the thermostat coolant housing only thing is I got it booked in the a remap tomorrow morning would it be a problem

I would say yes if it's going on the rollers.

i would say wipe it and see if it persists might just be the cold weather starting to niggle at it !

 

if it comes back get the place thats doing the remap to fix it before they do the remap surely it shouldn't be a problem for them.

Is it at the flange or the hose connection?, mk1 or mk2 octavia, petrol or diesel?

Ye it's on the flange its a mk1 petrol Vrs

Ye it's on the flange its a mk1 petrol Vrs

 

 

theres no hope then 

Just couldn't put it on the rolling road coz of the leak but it's going back on there when the new part is done
