problem with Audi A6

[jonathan karong]

Hello

I have an Audi A6 2.7L Year 2002, recently had damage underneath the car which resulted in engine oil and gear box oil leaking , I have since got these covers repaired and then replaced both engine oil and gear box oil. When I then tested the car there was no power when I tried to take off I have to rev it for about 20 seconds for it to start moving slowly .. Once in motion it drives somewhat normally but whenever I stop I have to go through the slow take off again.
Also the dash board gear indicator is not responding when I change gears, all of them are lit up whichever gear I engage . I have taken it to diagnostic and the following errors have occurred

1. 16684/P0300/000768 - Random/Multiple Cylinder Misfire Detected
2. 17965/P1557/005463 - Charge Pressure Control: Positive Deviation
3. 16689/P0305/000773 - Cylinder 5 Misfire Detected
4. 16690/P0306/000774 - Cylinder 6 Misfire Detected
5. 16686/P0302/000770 - Cylinder 2 Misfire Detected
6. 18010/P1602/005634 - Power Supply B+ Terminal 30: Voltage too Low
I have since done a minor service changing spark plugs and filters, but the problem is still there.
Please can you assist me .

Assuming it's a tiptronic gearbox, the symptoms sound like low oil level.

As the oil has been changed lately, check the level using the (long-winded) Audi procedure to fix the problem or at least eliminate it as a possible cause.

Does the engine rev-up quickly and cleanly when in neutral? if so, clear the fault codes and try again once you've checked the tiptronic oli level.

If it's a manual box, I give up....
