Limp mode is generally engaged when the ECU detects a sensor input that it is not comfortable with, IE not enough signal output to support higher RPM operation. The trick is to find the sensor that is either bad, or reporting below normal output. The dealer may need to scan the car to find this..The oil temp limp is just one cause, and not a factor here obviously..
While this is a chart from a Motronic system (VW/Audi) it gives you an idea of all the sensor inputs that are used to feed the ECU..
