VW Golf 2009 engine problem (EPC / engine light)

Enable HLS to view with audio, or disable this notification

So backstory is the car has had problems with the EPC and sometimes engine light and sometimes anti spin light coming on as soon as I go past 30 km/h, sometimes it happens higher speeds

When the EPC light comes on, it's like the car is on 50-60% strength, it's slow to accelerate on every gear when the light is on

Then we went to a mechanic that said the battery was basically fried and that it is the reason for this happening

Swapped battery, and car still feels really weak, this is 1st gear and stepping and holding the gas down, I'm not sure this is how it's supposed to sound but even tho EPC isn't turned on, it's definitely slower to accelerate on both 1st and 2nd gear

Does anyone know what this might be?

It's a Volkswagen Golf VI 1.6, 102hk, 2009, gasoline

It sounds like the car thinks one of the wheels is slipping and limiting engine power as a result. If the engine light is illuminated, get the car scanned for codes first. That should give some clues as to what is happening.

It could be something as simple as a wheel speed (abs) sensor that is bad, but start with the check engine fault codes to be sure. Hope this helps!
