Crankfoam

[BiscuTMonkeY]

Basically overfilled the engine oil of my 1.8t 99 A4 by nearly 500ml drove on the highway for around 60km before the music was turned down and heard the noise, the car then proceeded to the nearest highway exit at around 100km/h upon reaching the exit the car slowly died and now will spin but not fire. I have already dumped oil and replaced spark plugs still same issue first kick sounds like it goes to fire but doesnt is this now the cat converter?

If it had a blocked cat it would normally start up ok and then slowly die as the pressure builds up. After you turn it off you can hear the pressure escape. Are you sure the oil level was the issue? 500ml isn't much.

I wouldn't have thought that a 500ml overfill would be enough to do damage (especially in such a short timeframe) but who knows.

Enough to fill into the crankcase and cause the oil to foam then the car died have replaced sparks and oil
Will the car do anything when the key is turned if any major damage has been done

If the oil foamed enough to starve the bearings of oil flow you will have had a low oil pressure warning light come on the dash. If you continued to drive with no oil pressure then the engine would start knocking or rattling. I don't see how it could have affected the cat unless somehow heaps of oil was getting into the combustion chamber. If it had you would've noticed a big trail of blue smoke out the exhaust. I am no mechanic but if it now has the correct amount of the correct oil in it, then starting it and running it for a short while shouldn't do any more damage. If the bearings/big ends have run without oil then the engine will be rattly or have knocking sounds from inside the engine. If it sounds normal then it should be ok assuming you didn't drive with the oil pressure light on.

Were the plugs oily? What did the oil look like?

Have you checked for spark, fuel and compression?

[Umai Naa!!]

Yep, back to basics first.

I know what the codes are and judging by what ive seen i need to replace? The wastage bypass regulator valve or just check? And my camshaft position sensor is gone or i need a new distributor?

If the CKP sensor has failed, it won't start.

You can Google the codes through the VCDS/Ross-Tech website, to get their descriptions, and in most cases, some basic trouble-shooting advice.

I got book with what the codes mean so i replace that sensor can i erase codes and start?

With your code reader, erase the codes, and see what comes back.

If it comes back, view the live data of the engine speed while cranking. It'll either show up, or it won't.

Hope these help.

N75 boost solenoid failure is common, as is a faulty throttle body. But do the diagnostics first, to confirm.
