After being recovered i found the drains blocked and both relays under the ecu on passenger side under windscreen cowling were under water. I changed them. Now the problems are. No lights wipers interior light mo dash light guages at all. The car will fire up for 2 secs and then shut down. Any help will be appreciated. Also cant find the body comfort control unit. Thought it was under passanger floot carpet but only a dry phone module. Please help. 

Oh its a 4.2 v8 quattro 2005. A6 

Worried it may end up in the breakers yard. 😫
