Sounds like we are in the same 'neck of the woods' as we shop in Barnstaple, Bideford and Tiverton! I have a MIB1 Amundsen and I have to admit I always have the map display set to 50m or 100m so I can't say if the same problem exists on the MIB1.

That's the problem then, AC is just as useful in the autumn/winter as in the spring/summer because by cooling the air it dehumidifies it which greatly improves the speed of clearing fogged windows. All my cars since 2000 have had AC, both auto and manual, and I have NEVER turned the AC off in any of them - even those with manual AC.

When I KNEW that there was a software update available for both my Amundsen MIB1 and my engine ECU my then Skoda dealer (I've moVed since) not only refused to apply the updates but even had the cheek to tell me there were no updates

I have a similar feeling about lane assist on our second car, a 2020 Toyota Aygo, it too makes far too many 'complaints' on non M or dual carriageway roads - but at least when I turn it off it stays off. Seems to me that lane assists isn't fit for purpose on anything other than M or dual carriageway roads.

On a previous car (Audi RS4) this problem was caused by a restriction in (or too small a diameter) pipe to the clutch slave cylinder.

I've driven under that bridge many times on the way to MIRA, it was always worth checking it out for some new "scars"

@cboyle7you've posted in the Octavia 4 forum but your profile says you have a Fabia?

Which given that most Brit's don't tend to complain isn't likely to happen .... unless social media is stoked into action?

To clarify for OP, that's an adaptation channel change not a coding change.

One story I read said it would be synthetic fuels made by extracting atmospheric carbon - so it would be carbon negative.

Reformat it to FAT32 but select the option to make the cluster size 4KB instead of default - that will stop the many small files wasting so much space.

I keep doing that too

A few years ago when I was working for an automotive consultancy one of the development engineers at Ford Research Dunton expressed the opinion that he would never buy any new model in its first year as, in his opinion, new models were usually rushed to market before they had the bugs fixed.

A relative put Redex into their Octavia III and got plagued by random O2 sensor problems which went away when they stopped adding the Redex.

Any sign of the Amundsen MIB1 2021 maps yet?

VAG seem to change their mind seemingly at random depending on year of manufacture and market - for example on my 2007 Audi the media would stay on until I removed the key but on my 2015 Skoda it goes off when I turn the ignition off; and on US websites many Audi owners complain that even on earlier model years it behaves this way instead of the way my Audi did. So it seems model year, market, and how the VAG software guys "felt" are factors that determine when the media goes off

Same here.

Are you 100% sure that your 2008 Octavia PD170 has a DPF?

My 2p worth .... service - yes. cambelt - no, too risky for me to try without the proper tools. waterpump - probably but only IF it can be done without disturbing the cambelt.

Some cars have been held in a lot for well OVER a year - when production exceeds demand it's happened. Have you not seen the pictures of a large airfield near Huntingdon absolutely full of unregistered cars a few years ago? Conversely you can get a 2017 Model Year car on a 16 plate - because Model Year changes in early Summer, so a newly built car registered in August can be for the next Model Year.

If your sat nav has a USB connector on it then it will NOT need 12V (no USB connectors have ever used 12V), all you need is a USB-C to USB lead.

Looks like you have some fuse checking and wire tracing to do - don't ignore the 49493 no communication with instrument cluster as this plays an important role in the immobiliser to ECU communication.

Not MADE, first registered - there have been many examples over the years of cars sitting in a holding lot for months, sometimes over a year, before being registered.

If you have a spare key, try that. Fault finding this over the internet isn't possible, you'll need to get a fault code scan done (I always suggest using VCDS but other diagnostic tools are available) which will give information about why the immobiliser is unhappy.

Starting then turning off after a few seconds = immobiliser.
