does it really make a huge difference? checked the s6 handbook and right enough, it does say to use the high octane stuff . .

Yes it makes a difference. The ecu has knock detection, so you can run both, but with a power loss on lower octane. When the ecu detects detonation it will pull timing/boost (another reason you dont want a bleed valve as then ecu cannot lower boost, only pull timing when it detects knock).

You also notice the difference if you get a batch of bad fuel, depending on how the fuels octane has been raised (e85 or octane boosters?) it can go off, so some sites are better than others depending on turnover.

ok, that's a lesson! i'll give it the fancy stuff next time and see how it performs. i had a look through that fault list on the smjautotechnik but it's gobbledegook to me i'm afraid - i wouldn't have a clue where to start!

What are your plans for it? Run as is or get it chipped?

i want to get it running properly as standard, andy and then i'll think about taking it further from there.

do you know of anyone up here who really knows these engines and who could set it up properly for me?

[Andy10v]

Sounds like a sensible plan.

No recommendations I am afraid, I fix everything myself, then you know its been done

Likewise.
Unless you have super deep pockets, you need to start learning about your car
With the 20vt I'd be super surprised if you can't find all the help you need on S2forum

andy, would you fancy taking a look at this old tub the next time i'm heading to perth to see the family?? you could always take it for a spin and let me know if you think it's down on power etc.

I am quite happy to do a boost leak test and give it a look over, just drop me a PM.

We can leak test, clear codes, take it for a run and check for any codes again.
