Sump plug - what size for 405 Diesel

We have a Peugeot 405 Turbo Diesel with a 1998 cc engine. Can anyone
tell me the type and size of the plug for the oil drain on the engine?
Square, hex ... and size.

Thanks in advance.

my 405 diesel has a 7mm Square.

 

Thanks. I thought it might be square, since I machined something up once
on a milling machine do do the job on a Peugeot 306. I have lost the bit
I made though. I would not have made a hex one - too much like hard work.
