MK3 Octavia - List of Defects, Faults and Issues

[Snail Style]

Dealer fix is to just insulate the speaker grille with double sided tape, anyone replacing it hasn't done their job properly. Most common faults I have come across with the Octavia 3 have been related to the 5F module in the glovebox, have had to update a few and on two occasions order a new one.

What is a 5F module?

Ive got a rattle coming from the glovebox or left front vent.Very annoying starts at1500 revs till about 1800.
Is this related to the glovebox thing.

SS when you say 'dealer fix', it seems to imply that this is a common problem?

Seems to be afterdarker! More common in the VW's I was told. My dealer said they were going to remove the cover and re attach it using some sort of tape, which I wasn't sure how good might have been.

But since wedging a tiny bit of foam, I don't hear the reverberating noise anymore and I am happy with that. Will just cancel the booking with the dealer.

Could be a wiring loom mate. Get someone to drive while you sit in the passenger seat to determine the source of the rattle.

I had an annoying rattle from the dash from day 1, and I was certain it was something behind the screen. Turned out it was the interior rear view mirror/rain sensor housing that was rattling because the sound actuator was vibrating the windscreen, which in turn was vibrating the rear view mirror housing. The problem happens only during acceleration and stops when I held the mirror down.

It has stopped now but if it does come back, the plan is to wedge some rubber foam between the housing and the windscreen.

If in doubt, use the foam wedge.

disable the sound actuator while you are at it

disable the sound actuator while you are at it

+1 for that

Had a 'Check Coolant' warning on the dash this morning and upon checking the reservoir, the level was below the minimum mark. Rang the dealer and they offered a free top up whenever I could drop in.

My vRS is less than 3 months old and done just 3000KM. I'm thinking the dealer didn't do their PDI properly, considering the poor condition of paint when the car was delivered. But I am also going to keep an eye just in case there is a leak somewhere.

Anyone else had this problem? Is it normal for the coolant to run out so quickly? Thanks!
