The Gunners manager and midfielder Samir Nasri have been charged for "inappropriate language" towards Swiss referee Massimo Busacca after the final whistle at the Nou Camp, where Arsenal lost 3-1 to Barcelona and crashed out of the Champions League after having striker Robin van Persie controversially sent off on Tuesday.
Busacca caused uproar by showing Van Persie a second yellow card for shooting at goal just one second after he had blown the whistle for offside - the Holland forward claimed he had not heard it due to the noise of the 95,000-plus crowd.
Wenger confronted the Swiss official after the final whistle over the sending-off and angry exchanges continued inside the tunnel.
UEFA, who could yet take further action following Wenger's latest blast, will hear the disciplinary case on March 17.
The whole incident has overshadowed what was a fine performance by Barcelona, who dominated possession as Arsenal failed to muster a single shot on goal.
Nevertheless, Wenger remains unrepentant and insists he has no case to answer.
"The only thing that people remember is that the sending-off killed the game," he said.
"A bit more humility would do UEFA some good. To apologise for what happened would be much better than charge people who have done nothing wrong."
There have been suggestions Wenger swore at Busacca, who is reported to have not held back either.
The Arsenal boss, though, would not divulge any firm details of the alleged exchanges.
"I will keep that for UEFA if they really want to know because I will have some interesting statements to make about some statements made by people who were not supposed to say what they said," he said.
"You can check any statement I made on television after the game. If I have done anything wrong I am ready to be charged.
"As for what is said in the tunnel, if you can get just one [time] where I have come out on what has been said against me or against the referee [in a tunnel] during my 15 years in England, I will pay for you to have a big holiday."
Wenger feels it is UEFA who should be answering questions over the whole incident.
"We are out of the Champions League, we have lost one of our big ambitions, we have been punished with a lot of damages and, on top of that, we have to say sorry to UEFA. We have done nothing wrong," he said.
"They organised the competition. They named the referees who come to the games.
"When you have a football game of that stature, you cannot come out with decisions like that and show a lot of arrogance on top of that.
"We can all understand that we can make wrong decisions, but after that it becomes dictatorship. It is not any more common sense."
Arsenal head to Manchester United for tomorrow's FA Cup quarter-final without captain Cesc Fabregas, who has aggravated a hamstring problem, while the full extent of goalkeeper Wojciech Szczesny's hand injury has yet to be determined.
