2011 Audi S3 8P

Good Afternoon,

Had a very strange problem come up with my car. Can drive it around normal and everything is fine, Bring the car onto boost and it flags up a "NO OIL PRESSURE" message in the centre display. Turn the car off, try to start it again and it sounds like the battery is flat and only does 2-3 really slow cranks.

Today i put a new battery on and its doing the exact same thing. However, if you disconnect the battery and reconnect it again the car starts again.

Has anyone come across a similar problem to this? Is my CDL block toast or is it something strange with the wiring?

Any help is massively appreciated

Many Thanks

Cal

Error codes?

This is what im not understanding, i have used carista and am not getting any error codes or limp mode.

One thing i do continuously get is a Low Voltage code to most units on the car (I.E Heater Controls, Headlights, Radio)

Then
1. Remove and clean the battery contacts.
2. Check the ground connection from the battery to the chassis and tighten the bolts
3. Check the plus connection from the battery to the start motor and tighten the bolts.
