Coil pack?

[Majic]

Hi.

So i haven't drove my car for 7 days. It started normal than after 20 miles of motorway normal drive i started feeling like it lost a bit of power. Than when coming to roundabout it stalled and it continued to stall at every roundabout. Basically when idling. Revs when on idle go chaotically up and down.

Local eurocarparts had only 1 coil in stock so got that and replaced each coil with it and started engine but nothing really changed.

Ive checked coolant, oil cap,dipstick and for blue smoke and nothing so its not a head gasket.

Here is a short video:

Can it be more than one coil failing?

If it's a 1.8t some of them had a coil pack recall from Audi

You need to get it read for fault codes.
From your description the MAF sensor would be my prime suspect.

Ill get the codes read tomorrow.

If i remove the plug from maf should that tell me if maf is bad?

On some VW's, Skoda's 1.8T's unplugging the MAF can be used to help diagnose a bad MAF, but I'm not sure that applies to Audi.
Certainly on Audi 1.9 TDI's unplugging the MAF just puts it into limp mode.

P0171 - engine to lean
P0300 - multiple missfire detected
P0303 - cylinder 3 missfire deteced
P0304 - cylinder 4 missfire detected

New coil packs on 3 & 4 needed. If that doesn't solve it the coilpack loom has probably failed.
BTW. If the coilpacks are a revision covered by the VAG replacement campaign your dealer will replace them free of charge.

If it wasn't tightened properly it would've just blown it off, that has come apart at the joint.
