In all fairness I purchased my Octavia from Arnold Clark in Hexham and had no issues with either the sale or after sales suppprt.

Good choice, the 1.4 TSI is a little gem.

 

The 1.5 TSI will end up being a good engine when Skoda finish developing it properly. Until then it is best avoided in all configurations.

Thank you very much. I started with the 1.5 TSI as my favourite for twinter pacck, but after reading all your comments I understood that the 1.4 TSI was was the right choice for me.

 

During the drive test I tried to change gears "manually" and it was really tricky because I couldn't hear the engine much. My previous one was an old Seat 1.9 TDI.

 

 

Talk about polar opposites 😂

 

The 1.9 TDI PD is almost indestructible, but calling it agricultural is being kind. Still, it is well documented as being one of VAG's best engines.

 

The 1.4 TSI is, in my opinion, another VAG success. Silky smooth, eerily silent, and now well proven to be very reliable.

What about the Dry DSG in the Octavias? 

You picked the right car.....& feed the engine super unleaded...if its the 140PS it'll push out 150PS no problem just kept in top condition...mine puts out at least 167BHP & 267Nm.....no remap..... besides Shell vpower the only "mods" are ITG panel filter, 0w40 Castrol oil to VW spec, heat shielding to the intake & turbo pipes, & cold air only intake (GTE Golf intake)….& pulls like a train & spins 225mm wide tyres easy...…(lead foot syndrome)

Is 98 octanes petrol better for this motor than 95?

I've found no difference using 98 or 95 on my 1.4TSI.

If its the 140 or 150PS then yes super unleaded is better for it..& the engine can make more use of the higher octane rating

The 1.4 is tuned to 95 octane fuel so all 98 octane does is improve it's resistance to pink or detonate before it should, making the engine smoother, it has no bearing on power at all, fifth gear proved this a good few years back. What has a bearing on power is the small mods you have done to intake track

The 140/150PS version has adjustable camshafts.....50deg on the Inlet & 40deg on the Exhaust.....so the timing can be advanced or retarded....putting higher octane in & the ECU can make more use....

 

& yes my other mods will help, but not all of the 26+bhp!!

What does the fuel flap sticker say?

Min 95 octane, means just that 95 is the minimum and you will benefit from using 98/99 octane.

If it says 95 or 91 minimum then use 95.

Where do you live? I would have killed for the winter pack when I was living up north...

... only if the ECU has been mapped (by Skoda) to make better use of the higher octane rating fuel.

 

Just because the mechanical system has the ability to advance/retard the timing to make use of the higher octane rating doesn't mean that the software will take advantage of that ability.

The ECU does not have to be "mapped" only for 98RON to make use of 98RON....

 

The software is written to make use of the fuels in your country...we (UK) have 95/98/99RON...in other countries they only get 91/95RON...so the ECU is written differently...

 

Even disregarding the specifics of a "map " for 98RON, the actual ECU is mapped for various load, speed, temp conditions & looks for various data inputs....the actual fuel burn characteristics between 95RON & 98RON is different, & therefore the ECU will receive different data..so at the very least the same data but at different time frames due to the way 98RON combusts...

 

Also in the EA211 engines the amount of injections of fuel into each cylinder per phase can vary between 1 & 3 depending on the data it receives....

 

this is why a car on 98RON feels more responsive/quicker...due to the way the fuel burns compared to 95RON....

 

These 1.4lts like the old 1.4lt AUB in the MK1 Fabia do respond to 98RON very well!!..in fact that engine had to run on it as stated on the fuel filler cap & in the brochure...…

Strange that mine is 140 tune and have run 95 octane fuel and 98 octane fuel (4 tank fulls of each, each tank one after the other empty to full of 95 octane, then 4 tank of of 98 octane, empty to full) so should of seen or felt some difference, but their was no difference in power what so ever, just smoothness of running as 98 octane is more resistant to detonation or pinking.

 

I say again fith proved this on TV a few years back. 1.4tsi is tuned to run at it's optimum on regular 95 octane fuel.

 

My car feels no different on 98 octane then it does on 95 octane, therefore i've gone back to 95 octane fuel as i see any point spending out more and not getting anything in return.

No sellers of 98 octane in the UK, so 97 Ron min, BP, esso, gulf etc super unleaded. And 99 Ron min Tesco momentum 99 or Shell V-Power Nitro, +

My bad i keep putting 98 when i know it's 97 octane 

BP stopped selling 102 and 98 years back, and when Shell change the name to NITRO + they went 99 Ron min, and it can sometimes be 100 plus depending on if European winter bought in.   Costco are 97 Ron again not 99 as their super unleaded was.  Greenery supplied.

forgot it was that years ago (Shell vpower)..& that's what my old Fabia stated (98RON) on the fuel filler cap...

 

current Shell vpower like you say is now 99RON & "+"...

Same here.

 

Since 97/98 octane offers no benefit in feel or performance (according to the butt dyno) that suggests that the range of allowed timing variations is not wide enough to be able to take advantage of the higher octane fuel.

Isn't it ignition timing rather than cam timing that would be altered by the engine ECU according to knock characteristics of the fuel used (as per knock sensor activity), anyway?

I may be wrong 😬, but my understanding of the variable valve timing on this engine, was that it effectively made it use the Miller Cycle of combustion at lower engine speeds. At higher engine speeds the valve timing changes so it is the normal Otto Cycle.

Its for economy and low range torque rather than any additional power. 
Toyota use a similar system on the engine of their hybrids but have an electric motor to provide the low end torque, and so don’t need a turbo.

Exactly....& it also uses the two lambda sensors...this reading then specifics the amount of air or fuel to the ECU as it tries to keep the lambda readings as close to "1".....fuel that has a better/cleaner (more complete) burn helps... 

 

& the 140/150PS engine has two hall sensors..one for each camshaft...which sends data on camshaft position & thus timing data back to the ECU….to then tell the camshaft control valve actuators to advance or retard the camshafts...

 

& that's before we talk about all the various other air intake, charge pressure, temp sensors the engine has...
