Recently purchased a 2017 octavia 2.0 TDI and noticed a harsh engine rattle under light load. From reading online I suspected that this is pre-ignition rattle and might be remedied by using higher cetane fuel. I'm in the UK and put a tank of BP Ultimate diesel (guaranteed cetane number >55) in instead of my usual Tesco fuel. Low and behold, the rattle is all but gone. Anyone know if there's another fix for this rather than using expensive fuel as this negates the economy of a diesel. I've read that it's possible to have the injection timing recalibrated but can't find much on the topic. Anyone knowledge about this?

Interesting. Thanks for the input. I'll mention the reset possibility when I approach the dealer. I'm guessing it's something they'd have to do.

From what I read DCC is an option and not fitted to many. I'm pretty sure all mk3 Octavias have the drive mode options irrespective of trim. Just wondering if there's something up with my steering system.

Shamelessly bumping this thread in case anyone has any thoughts. Drove the car a bit more now and it does seem that putting it in eco mode does limit the power but no noticeable change to the steering when changing from eco/normal to sport mode. This is bugging me as I find the steering a bit light for my tastes. I have a 1 year Skoda warranty so will probably get them to look at it. Anyone experienced this or have any insight as to a possible cause?

Just purchased a 2017 octavia tdi from a Skoda dealer. The drive mode selection appears to be working but is having no noticeable effect on the steering or throttle response. I test drove another octavia and the change was clearly noticeable. Anyone experienced this?
