What did you do to your Octavia today?

[Martin]

It appears the 1.8tsi only has 1 O2 sensor between cat1 & cat 2 whereas the 2.0TSI has 2 sensors? One directly at the turbo outlet before cat1 & another just in front of cat 2? Does that sound right for the 2.0L (both belt & chain drive versions).

Keep in mind I'm at 142500km.

I do believe the 2L has two O2 sensors and one is even a wide band sensor
(but the ECU seems to run more off the map as at times I have a fuel haze out the back)

Ok - I'm a long way from needing to clean the O2 sensor - thanks

Wire around the flex joint of the DP I think. flex joint must be a bit loose

Sorry Mysticality but other than shiny misshapen bit of metal left of centre what is exactly am I seeing as a "fixed" issue?

Sorry, yes, exactly this.
Flex joint cover was rattling something chronic, only at 2,800-3,100rpm so was difficult to pinpoint, but we got it! In the end...


Have now left my baby at the dealership for awhile, 2nd gear, 1st gear and 3rd gear synchros all went in the brand new 9,000km old gearbox...
Heres hoping its another warranty job! Argh!
I have a brand new whineline front/rear ARB to go in too!

The Mazda dealer I used before all my Mazdas went used to do the upper engine cleaner as part of their service, about $100 extra. Only place I know that did and it made a difference.

Fuel Filter & Air Filter.
Bought UFI brand of eBay and was unsure of the quality & only when changing the fuel filter realised that the OEM VW init was UFI branded, so I'm happy with that.
For reference: OEM partno 1K0201051C. UFI partno 3184000

I did the last fuel filter at 60,000km and forgot it was due at 120k so was keen to see how much rubbish would come out after 82,500km. Surprisingly, after a shake & back flush there wasn't much in the way of loose contaminant.

I do air filters at 45,000km and the unit that comes out never looks any different to the new one, so nothing to report there.

Front ARB requires the x-member to be dropped. Do they have to faff with that when they remove the gearbox? If so, get them to put it in at the same time.

My 2.0TSI only has two o2 sensors. I thought it was only America where some 2.0TSI's had the 3rd sensor? (On the turbo exhaust housing)

3?

I feel so ripped-off.

I've only got 1. It's on the top of the DP half way between the #1 cat & the #2 cat

I think its something to do with their pollution laws/emission testing in places like California.

Got the Opticoat applied. Time will tell if it was worth it.
