World Touring Car race winner Pepe Oriola will return to the championship for the final three rounds of 2014 in China, Japan and Macau.
The Spaniard will drive a Campos Racing TC2 class SEAT Leon.
Oriola first campaigned the model in the WTCC in 2011, before switching to a Tuenti Racing Chevrolet Cruze in the second half of last year.
"Despite having many offers on my desk, I did not want to leave WTCC," said Oriola, who will also act as a driver coach during the season for Campos's European Touring Car Cup drivers, Ukrainian Igor Skuz and Russian Nikolay Karamyshev.
"With Campos Racing I have the opportunity to remain active in the championship, bringing my experience to the team and its drivers."
Campos has also announced a late deal with reigning European Touring Car Cup winner Petr Fulin to race in this weekend's WTCC season opener in Marrakech.
The 37-year old from the Czech Republic will be at the wheel of one of the team's TC2 SEAT Leons, alongside French teenager John Filippi.
