Hello everyone,
Its an older tread, but I am also experiencing this issue now, and thought check in. I have a 2013 Aventador, no aftermarket exhaust, 9000 miles now, and did the recall 6 months ago (related to the cold junction repositioning), and a 1000 miles later i all of a sudden got the catalyst overheat warning. My reader stated 3 codes, P11EB, (manufacturer defined) P11ED, (manufacturer defined) and P0546 (exhaust gas temp sensor high). See attached
I called the dealership here in Texas, they stated the normal "have to take it in to have a look and assess". Been waiting for almost 2 weeks now, and still not able to get an appointment with these guys, so started to explore other routes.
My local (exotic) workshop has stated that it looks like all the cat temp codes for one cylinder bank is defaulted.
This the ECU or the exhaust gas sensor(s) / thermocouple that needs to be replaced? Anyone have any input on the going prices / time for having these repairs done?
I fear they messed up something during the recall, never had any issues with my car ever before.
Pleased to hear
