Removing only the butterfly valve tricks the computer that the Maf is running fine leaving the EGR to function. but leaving it for a few days won’t cause any major issues and the Dpf will know it needs to regen once it’s all connected again

They are all connected in a computer sense. Removing the swirl connector increases the MAF reading which in turn will create an EGR error forcing it to stay shut 100% of the time

Dpf needs MAF readings and EGR readings to be correct to initiate a regen. With the swirl connector removed it will cause higher Maf reading because the EGR will be shut off.

The only consequence this will have will be the EGR being shut off. The car will run great but you may have issues with DPF regeneration because the engine senses a fault.

With the swirl flap valve disconnected you will certainly see a higher Maf value because if you disconnect with the engine running you’ll here the EGR shut. To be honest I didn’t notice much difference mapping out the EGR less power if anything. But that swirl flap can cause all types of clatter.

Just saw your message. Absolutely you’ve solved the problem

That’s fine with Obd11 run a scan and you’ll probably get errors for the TPS and swirl flap Valve. clear the faults and switch Car off and On again and check faults again. If nothing appears start car and check engine. Only thing I can think of is you haven’t connected TPS connector properly...

Sounds like your lacking air. have you made sure all connectors have been connected back Correctly ?. Anything blocking intake ?. Rag or something ? do you have VCDS ?.

The strange thing is that when I run engagement point adaptation with VCDS the gearbox then runs as smooth as silk and changes gear when it’s supposed to. But after a few days when it has runs through the different calibration steps it goes back to being a bag of nails.

Thanks John were you getting intermittent symptoms?. Some days smooth as silk and others rough as old nails ?.

Many thanks for the reply yeah, oil and filters changed every 35,000kms. I even got a software update from Audi but that didn’t help. They say theirs nothing wrong but I can feel the difference like night and day when it runs smooth and rough. I can almost feel jolts between gear changes when...

Do you have air suspension?. Just do the 402 mod

Shame I’ve got a black edition for sale but I live in spain.

Ok So I have the same problem. I don’t think it’s your battery. I believe it will possible be the start button. if you press the start button down hard when you start the engine it shouldn’t show an error.

Hi All I have a 2012 with 7 speed s tronic. For months I thought I was having engine issues because the car would feel more lumpy and have less power sometimes but after checking everything I think it may be the transmission. no faults what so ever and have also tried calibrating clutches...
