Hello everyone,

Just registered on the website and saying hi. Currently own a 2016 Octavia 3 2.0 TDi estate. Bought second-hand but love the car after 2.5 years of driving. A couple of niggly little faults which led me to this website.

The car is nicely broken in with 115,000 miles - roughly middle-aged. Am looking to keep it going as long as I possibly can as I don't believe cars are disposable items.

Look forward to learning as much as I can from you all, and hopefully being able to contribute to discussions.

Good morning Mark, welcome to the forum.

What are the niggly faults you have?

Thank you.

I have a problem with the heating / cooling in the cabin. I have seen the fixes for resetting the blowers which works for a bit. But the main problem is that I don't get hot air out of the drivers side vents. Passenger side is good. Not much of a problem at the moment as the weather is nicer but I want to get it sorted before autumn and I have ignored it for too long. I have found a post relating to a problem with a "magnetic valve" which may need replacing - i just need to locate it, and may have to fork out for a Haynes manual - i don't think they are as good as they used to be.

ALSO, and I think it might be somehow related... the engine idle speed sometimes remains at about 1000rpm (when coming to a stop at traffic lights, etc), even after the engine is up to temperature. It isn't doing it at the moment, sits at 750rpm. But I can sort this out (sometimes) by turning the stop/start feature off, or turning off the heating/aircon blowers.

Again, it's a temperamental problem that happens totally unrelated to whatever the weather is.

Appreciate any pointers or assistance. I am reasonably confident with repairs but would like to be able to do this myself instead of taking it to a garage.

Hi markyp27,

welcome to the forum, youve already had a look so good stuff. the beat place to post the niggles are in the octy 3 sub section. lads there will help you out.

if knocking off the aircon drop the revs then its load related, or if the fans are running on after shutting down alot it could be the dpf struggling to complete a regen.

my moneys on the load though i wouldnt worry about it too much. the heat weve been having aircon is needing to work alot harder anyway, so gonna put more draw on the system. if its not just the aircon causing the idle speed increase, check how the battery charge is and how its doing while the alternator is engaged.

Re. the heating issue, check if the coolant expansion tank is marked 'Mit Silicat' on the side and check the colour of the coolant, there is a possible issue of the Silicate 'Teabag' contained in the E.V. breaking down and releasing granules into the coolant - partially blocking coolant passages, especially in the heater matrix.

Thank you both for that info. I will check out the coolant tank tomorrow. I must admit the coolant does seem to have a bit of a film on the surface of the liquid - maybe a flush is needed

Thanks again
