S6 timing

Rich's screen shot:

A better image solution is what I suggested: a screen save, i.e. Shift/Print Screen, Paste in something(Paint, whatever), Trim,Save, upload, post).

There's no feedback weather it worked ok or not. I'm very warey of fakes nowadays

Maybe stick a new thread up, "has anyone bought a good MAF lately?"

Did you have a look on Audi Tradition?

I always test all the small bore vacuum/boost lines individually. Pull the line off the inlet manifold, set your compressor to 1bar, get one of these on your air line and poke it into the line, pull the trigger and listen for leaks. You may need an assistant to check inside the car.

'In mint condition' ? Is this new or not???

I am not sure why they use that term but it does put you off. Perhaps a bad bit of translation. The word we want to see is NEW! I think I was reassured by a Parts guy in the UK that it does mean new and unused.
Didn't Error offer use of a new Maf to try. Would save another unecessary purchase.
So both of the Mafs produced valid readings in group 2 of the 10 measuring blocks at idle. Might be useful for someone else if we knew how the reading in group 2 relates to the AFR.

I can't quite see but is that 12.46V in the second pic?

At idle both MAF sensors read 24 in the value so theoretically good, and the same. However, under wot the AFR went down (richer) by just over 1%. Which doesn't sound much but when it's from 15:1 to 13:8:1 it's quite a difference in performance so I'm thinking that a NEW one would bring it about right. After all, even 'low mileage' used ones are 20 years old now!

Only 124 load at 3600 rpm. Should be more like 180. That's why it doesn't run properly.
Need a boost log.

Probably exhaust blocked (flexi inside out), restriction in intake or engine timed wrong.

This "Flexi" as in the corrugated metal boost dump tube?

If so, it is a one way installation. Arrow points in the direction of flow.

Proper orientation of the corrugated waste gate dump tube:

I did suggest the MAF hose may be getting sucked flat.

We should have thrown a few 10er's into a hat. Winner (correct suggestion) takes all.

Your suggestion is definitely plausible and a potential winner.

Think he had already replaced the maf hose with a new one unless the restriction is sufficient to collaspe a fresh one!

Ahhhh right ok. I don't think I have the equipment for a boost log and I don't know anyone who would do one either. The entire exhaust is new and I'd the second one now trying to sort this. How could I check for the hose collapsing? I have run the car with the top off the Airbox and it ran the same too.
How is the load calculated?
Is it possible that a new MAF would cure this??
