The oil leak you are seeing is almost certainly a leaking copper injector seal (the bit that seals between the injector and the cylinder head), and what you are seeing is diesel leaking up from inside the cylinder. Also look for black, coal like deposits around the injectors. If this is the case you should really see to this soon as it will only get worse.
Also check the big rubber hose that goes from the air filter box to the turbo housing. These can split, especially around the hose clip that secures it to the turbo, and I've seen them throw egr codes.
When I replaced my egr I had to reprogram it with VIDA, someone may correct me as to whether this is actually neccessary.
