The legal requirement is to always overread but by no more than 10%, so manufacturers try to get a vehicle to overread by around 5-7% when on brand new OE size tyres to allow for wear and tolerances.

It was like that on DSG versions of the Octavia 3 too - so it's not a new feature bug.

Correct it doesn't use satellites - the data is entered by people in a UK control room and is transmitted over RDS on selected FM stations.

Not owned many diesels so can't be overly helpful , but first thought is have you checked the fuel filter? Other possibility I can think of is an injector stuck open, have you smelt the dispstick? Does it smell of diesel?

Definitely, I've been using a HEX-NET on Skodas and Audis for several years.

Concentrate on the insufficient diesel pressure as that's what will cause poor running. Faulty glow plugs will just make starting more difficult.

... and probably best to post in the Superb forum, not the Octavia forum?

Why not compare the OE size tyres/wheels against your proposed size using a tyre calculator to see what the increase in diameter is (the rule of thumb is no more than 2% either way) and what the offset of the wheels will do to how far in/out the tyre is? An example: https://tiresize.com/tyre-size-calculator/

As with all suppressed zero graphs the impression created is much worse than the reality. The impression is a 600% increase in CO2 (one vertical line to 6) but the reality is an increase of around 33% - still bad but not as horrifying!

Octavia 3.5 is commonly used when referring to an Octavia 3 facelift (FL).

If you're a verified VCDS owner then Uwe normally replies pretty quickly to a PM on the Ross-Tech forum.

On the wheel hubs/bearings.

Sounds like an intermittent problem, possibly heat related, with the fuel pump control module (or wiring to it) caused the fuel pump not to run making the low fuel pressure a sympathy fault.

+1 It's often several hours out of date, the worst example I've experienced was telling me about roadworks that had finished a YEAR earlier!

I would treat that with a pinch of salt, looking at the Octavia 4 forum shows people waiting well over a year for their Octavia and some giving up and cancelling their order.

At least the coding, and possibly adaptation channels, will need checking as it depends on the equipment in the vehicle it came from and is going into.

No TMC on my 2016 Octavia either.

ITIS and Trafficmaster, I believe VW UK use Trafficmaster.

Same here, looks like VW haven't renewed the subscription to UK TMC.

I miss seeing the Goldfinches which were regular visitors to our garden in North Devon.

I never got that from my V8 RS4, even when I had to remapped to have a redline of 8600rpm - i just had to get the revs that high even more often 😁

I admire your faith in the product knowledge of Skoda dealers, but sadly I don't share it!

They often deserve their nickname of Halfrauds

I agree - the V12 is silky smooth and almost screams but lacks real emotion IMHO, however the angry thunder of the V8 makes the hairs on the back of my neck stand up.
