sporadic EPC after three weeks S3 ownership - youcanic scan points to particulate filter

[gwaijai]

Hi all,

as title suggests I have had my 2019 S3 for arond 3 weeks now, been enjoying it lots, this last week I got an EPC code on the dash and having invested in a youcanic scanner for my previous car did a scan:

P246300 - passive/sporadic - Particulate Filter Restriction - Soot Accumulation Bank 1
P24A400 - passive/sporadic - Particulate Filter Restriction - Soot Accumulation Too High Bank 1
P1A9100 - passive/sporadic - Particulate filter bank 1, indicator lamp active
P256300 - passive/sporadic - Turbocharger Boost Control Position Sensor Circuit - Range/Performance

U111000 - passive/sporadic - Function restriction due to communication interruption

B105313 - passive/sporadic - GSM antenna Open circuit
B153313 - passive/sporadic - GSM antenna 2 Open circuit

I am thinking the top four codes are linked, I can force a particulate filter regen with the youcanic, either on a run or at a standstill . I am hoping this will resolve the codes, I will let you know.

I think the bottom three are also linked, possibly water in the aerial from a recent power wash?

Just wanted to know if anyone else had similar issues and how they resolved them.

Cheers,

Gwaijai

OK so breif update;
EPC light was off but particulate filter and warning triangle lights came on when I started the car, so after a Boxing Day trip to A&E (don't ask) I gave the S3 a good run on the motorway and kept rpm around 2.5k, after about 10 mins the lights cleared. Not had a chance to run it on the Youcanc again, maybe tomorrow.
