S6 timing

[HMS-S6]

Hi. Mine isn't the fuel cut, it's far far less severe!

I just drove it on a very quiet wide road and WOT from below 3000 rpm it stutters and holds back all the way to 7,000rpm, very rarely clearing but sometimes does. HOWEVER if I take it on light throttle to 4,500 then hit WOT it pulls dead right EVERY TIME without fail. Any ideas anyone? Anyone? Please.

Hi all, I was advised to repost in this thread with a bit of advice I posted today; worth a shot as it worked for me.

If having issues (like I was) with intermittent stuttering at high revs >3000rpm, this is caused by the fuel pump cutting out to protect the engine: "limp mode". One reason for this can be a dirty MAF sensor. The sensor is easily removed by removing the jubilee clip and two bolts, then using a cotton bud and contact cleaner, gently clean the metallic sensing element inside the chamber. This was the definite cause of intermittent 'limping' which I didn't even know existed at the time. I thought I had an engine timing/misfiring problem. Luckily, it was an easy and free repair that even I managed; albeit after having the fuel filter, air filter, oil filter, engine oil and spark plugs changed at the garage

Take it easy, Grant

Right! New FPR didn't sort it either!

The ABY value would be the nearest AAN.
That all the info we have I think!

Group 000 2nd value is the Maf value in Vag com.

What values would you expect to see at 1.2 bar at 3500 RPM?
