Good day gents,
So, this morning my car struggled to start. Maybe on the 10th attempt it started, and then I noticed the SAI pump not running and the idle was very low. Usually it starts on the turn with the SAI running and the idle picks up to above 1k rpm then drops down bk to normal after a minute or so.....
Now I know most ppl delete the SAI but is it responsible for cold starts.
What could be wrong here and what do I do now apart from getting it scanned?

I do find it a bit difficult to wake up in the mornings and I don't run because I don't do exercise.

Who can do these deletes in Dbn?
Do you just need a diy kit or do you need vcds to also code it out?

Re: 1.8T A3 AUM SAI not running - difficulty on cold start
after using the car for a few days, it seems the SAI pump runs every now and again. When it does run, the car starts up fine and car behaves normal. However, when it does not run, I battle to start the car and when it does start it runs like crap until the engine is warmed up.
The code I got on VCDS was : 16825 - Evap Emission Control System
P0441 - 35-00 - Incorrect Flow
What do you guys think is wrong here ?
I know everyone says Delete, but would it resolve the cold starts and miss fires @ low rpm when cold

Evap code appears on just about every audi out there older than a few years. Does not cuase hard start not bad idle. Wrong tree to bark up at.
