Lexus LC Reduced Engine Power

Thanks for the reply! The error codes come right back almost instantly. I clear them, start the engine, and BAM, they're there again. So definitely a persistent problem. What was the fix for your Audi? Maybe it'll give me some clues. Was it something with the car diagnostics?

Okay, that sounds pretty consistent, unfortunately. In my case, the Audi's issue ended up being a faulty sensor. The computer kept getting incorrect data, which caused it to limit the engine's performance. Given your Lexus is still pretty new, I'd recommend taking it to a trusted workshop. They'll have the proper tools and software to diagnose the Lexus control system specifically. It could save you a lot of time and potentially prevent further damage.

Appreciate the advice! You were spot on, turns out the main relay was defective. Cost me 120€ at the shop, but at least it's fixed. Thanks for pointing me in the right direction!

Hey there! Sounds frustrating. I had a similar issue with my 2018 Audi A5. It wasn't exactly the same, but I also experienced reduced power and a ton of error codes popping up. You mentioned trying a system reset – did the error codes disappear temporarily, or did they just come right back? Wondering if it's a persistent problem or something intermittent.
