2005 Audi A6 Quattro, 73K miles, just died on me. While driving, the engine shut down and i coasted to a stop. Oil started leaking from bottom of car. Car will not start, had to be towed. Local mechanic removed skid plate and found a crack (i saw it too), says engine must be replaced. Speaking to an audi dealership by phone, they said you can't see the engine by simply removing the skid plate, that it must be the oil pan that is cracked. Any ideas?

Nothing. Car has been sitting at a repair place
Hi I would tend to go with the Audi dealership as the engines on these are well covered with mounts and manifolds which make it really hard to see the engine block. I would certainly request to have the car rechecked and a few more tests done.
You need to confirm exactly where the crack is and if possible get a photo of it and let me have a look on here so I can try to identify the part for you.
You need to confirm that the engine still turns over and it's not seized after loosing the oil. Also if it's just a crack in the oil pan the car shouldn't shut down so you need to find out why the engine cut out.
I hope this helps and if I can help further please feel free to ask
Here is a picture of the crack.
This was visible one the skid plate was removed.
Hi that is a crack in the oil pan but it appears to be cracked right above the subframe. This means that it's unlikely that something from the road has hit it causing it to crack which is quite a common fault. This crack seems to have been made from something coming out of the direction of the engine. Possible oil pump, crank or conrod failure forcing something out through the sump.
If this is the case you could well be looking at a replacement engine.
It's the odd shaped piece that worries me as that is the part that looks like it's been pushed out by something. The only sure way to know is to have the sump removed but it's not a simple job on these.
