Audi 100 - cutting out when cold

[randall977]

My 2.0 Audi (AAD engine) cuts some mornings approximately 5 - 10 minutes after starting when I get to a junction and declutch. It immediately starts again and doesn't do it twice (though after it starts again the revs are about 1200rpm for a short time). The temp sensor is new VAG, I'm pretty sure the ISV is fine. My local Audi specialist said there is a fault (a code showed up) but he can't exactly say where - maybe the CSV - but this wouldn't make it cut out.

Can anybody tell me about the auto choke - is there one? What about the rev switch below the throttle body (don't know the technical name)?

Any help really appreciated - thanks

Did you get the fault code recorded for yourself? if so, post it in the forum, there are many on here who would be willing to assist you with more detailed info but the code will be required.

I will try and get the garage to plug their fault reader in again - unfortunately a cheap fault reader won't work with this engine code. Thanks

I just got my local specialist to pull the fault code off and it's : 005870 - adjustment limit mixture (intemittent). I'm told it's most likely an air leak or the CSV (which I just replaced with another one). How do I track down an air leak - it's obviously very small if there is one. Thanks
