Dsg?

[Dv21]

Yes mate

Welcome to my hell.

Have you had your car scanned via vcds for faults?

Does it happen in sport or normal mode or just manual?

Has your dog been mapped

Have you had any dsg work under warranty?

[Dv21]

Yeah I did fuel pump electrics malfunction cleared it down hasn't come back tho they are telling me my in tank pump is giving up and I need a s3 one or ttrs one other people are saying its not that I am lost do you have a problem like this ?
And dsg has been mapped

[edd666999]

Car was fine, dsg fine until apr k04 conversion.

When I'm booting it, coming to a stop stalls the car.

The issue I have is psi tuning left a multitude of errors in my ecu non of which I can link to this issue.

In tank pump sounds reasonable as when I'm doing 30mph and no boost/no real fuel demand it doesn't stall.

[edd666999]

If you find the solution could you let me know, I'll do the same for you.

[Dv21]

Yeah will do mate it proper confusing I'm dropping it Friday so they can look into it

[edd666999]

I assume your down south?

Do you know what part number for fuel pump? The ttrs rs3 in tank one

[Dv21]

Yeah I'm in reading Berkshire I have no clue mate tell me does yours drop the revs and sometimes pick up and other times stall ?? Almost like pinking

[edd666999]

Yeah it sometimes very close to stalling, I have done no more than 800miles since the conversion in August though. I was hoping resolving my uneven idle might stop it from stalling. My alternator is causing revs to drop and rise so getting that and my battery replaced next.

[Dv21]

I've probably done even less miles than you I've fitted a new battery I'm thinking it could be mapping never ever did it before conversion I'm really baffled

[edd666999]

Well I'm apr stage 3, loads of people have that map and couldn't find any reference to the issue elsewhere.

Yours is a more custom map.

Maybe related to the custom harness that's made? Incorrect readings sent to ecu?

Im going to swap to the "g" DV too.

[Dv21]

The DV been changed on mine made no differents totally lost

[edd666999]

I was thinking dreaded dsg mech unit.

I tried a dsg reset which did nothing.

I hope it isn't lol that's a 2k job.
