Seat Alhambra Diesel Exhaust Temperature Sensor Issue

Okay, so I'm officially pulling my hair out! My Seat Alhambra diesel has developed a serious problem. The check engine light is on, and the engine feels like it's lost a bunch of power. Also, I'm pretty sure my fuel consumption has gone through the roof. I took it to a local mechanic, and they said it's a faulty exhaust temperature sensor, likely caused by a leak in the exhaust system messing with the emission control. Anyone else experienced this? Any advice would be greatly appreciated before I shell out a fortune for sensor replacement!

Sounds familiar! I had a similar issue with my Alhambra. Check engine light, loss of power... Was there any noticeable temperature fluctuation before it happened?

Temperature fluctuation, you say? Now that you mention it, I did notice some weird readings on the temperature gauge a couple of times before the check engine light came on permanently. What was the fix for yours?

Yep, that's exactly what happened to me. The temperature sensor was the culprit. I'd suggest getting it checked out by a professional to confirm, but it sounds like a classic case. Best to get it sorted quickly, as a faulty exhaust sensor can cause more problems down the line. Good luck!

You were spot on! Took my Alhambra to a trusted workshop, they confirmed it was indeed the exhaust temperature sensor. Sensor replacement cost me 265€, including labor. Check engine light is gone, and the engine is running smoothly again. Fuel consumption seems back to normal too. Thanks a million for your help!
