LFA Temperature Sensor Issue

Alright LFA fanatics, I'm pulling my hair out! My 2010 LFA, naturally with its glorious gasoline V10, is throwing a fit. Got 107950 km on the clock. The temperature sensor on the heat exchanger seems borked. I'm getting an error stored, a warning message flashing on the speedometer – talk about distracting! – and the air con refuses to play ball. I'm betting the AC control unit is fried. Anyone seen this madness before? I'm dreading the repair bill...

The problem is suspected to be a faulty AC control unit. A similar issue was resolved by replacing the sensor and addressing related AC system problems. The solution involved professional diagnosis and repair, costing 980€.

Sounds familiar. I had similar symptoms in my LFA. Error code, A/C cutting out… was the temperature gauge acting wonky too?

You had the same gremlins? The temp gauge seemed normal, reading in the usual range. What fixed it for you?

Yeah, pretty much identical. In my case, it ended up being the sensor itself and, unfortunately, some cascading issues with the AC system. Bite the bullet and take it to a workshop, they'll be able to diagnose properly.

Thanks for the heads-up! Took your advice and went to the workshop. Turns out it was exactly as you said: faulty sensor and the domino effect on the AC. Cost me 980€, but at least it's sorted now! Cheers!
