Seat Alhambra Diesel Stalling at Idle
Summary of the thread
A 2001 Seat Alhambra diesel is experiencing stalling at idle and a check engine light, with diagnostics indicating incorrect fuel composition. The issue may be linked to recent use of a fuel additive, potentially causing fuel mixture problems. A similar case was resolved by addressing a faulty plug connection to a sensor. The suggested solution is to have a workshop inspect and repair any sensor-related connection issues, which successfully resolved the problem in this instance.

I did use a fuel additive recently, trying to improve the fuel economy. Could that be the problem? How did you resolve it on your car?

That fuel additive could definitely be the culprit. It's like giving your car a food it's not used to. It messed with the fuel mixture and triggered the sensor. In my case, a faulty plug connection to a sensor was the reason for the error. I'd suggest taking it to a workshop to check the cable or plug connection. They can pinpoint the exact sensor that's causing the issue.

Big thanks for the advice. I took it to a local workshop, and you were spot on. They found a dodgy connection on some sensor related to the fuel system. 95€ later, and it's running smoothly again.

Sounds familiar. I had a similar issue with my Alhambra. Check engine light, rough idling, the whole shebang. Did you happen to recently fill up at a different station than usual? Or maybe used any fuel additives? Just thinking about possible fuel contamination.
