Audi a1 problems pleasePlease belp

[Krisjt]

Hey all, New here. I have an Audi a1, had it for a year now 2011 late had 24k when I brought it last year.

So about a month ago, when driving every now and then the car would knock back as if the clutch was being pulled up to fast but didn't have it down... Now; the car a month ago started to splutter and jolt again every now and then.... Put a snap on on it and got error code
" 4344-u1025 check fault codes in hvac, j301 implausible signal " anyways car was still driving
Just every now and then the problems Occured.... Now on Sunday the car on start up , started but then cut out after spluttering with no a creation power just slowly died and then after several attempts to start and keep the engine running the car would just die so having to use a jump pack to get it going again... But the crazy thing is if you leave it for a bit it will start again .... Which now the problem is happening daily like this. Apart from now once it occurs I leave it so prevent
Damaging the battery.

I've been searching for a while now but it's given me that many possibilities I don't know where to start would highly appreciate any support we use the car daily you see as we work Around our local community

Thanks
Kris

Have you checked lamda sensor or throttle control module. I would take it to a garage and get a diagnostics because 1 x code can bring up many faults.

You say you're having to use a jump pack - does it start up fine with this?

If so, might be obvious, but have you checked the voltage across the battery ? Or swap it out for a known good battery and see ..


I wouldn't have thought the HVAC code would be related to poor running / not starting. Was the idle rpm lumpy when it was running / just started ?
