Seat Alhambra Start Stop Problem
Summary of the thread
A 2014 Seat Alhambra with a diesel engine experienced a failure in the start-stop system, causing the engine to shut off at lights and trigger a warning light. The initial suspicion was a heavily discharged battery. After checking the battery voltage, it seemed okay, but further testing revealed low cranking amps, confirming the battery was the issue. Replacing the battery resolved the problem, restoring the start-stop system to normal function.

Voltage seems okay when I checked with a multimeter, but how can I be absolutely sure it's the battery? Could it be something else, like the starter motor or some hybrid vehicle issue?

Voltage can seem okay, but the cranking amps might be low. Mine was the same. Get it properly tested, but the symptoms sound exactly like what I experienced before the battery died. I wouldn't rule out the starter motor, but given the error message and engine stalling, I'd bet on a battery first. Get it checked at a workshop. They can properly diagnose it.

You were spot on. Workshop confirmed it was a battery problem. New battery installed, and start-stop is perfect again. Cost 290€, but it's resolved. Thanks for the help.

Sounds like a battery issue. I've got an Alhambra too. Had something similar happen, start-stop went crazy. Have you checked the battery's voltage? Sometimes, even if it seems okay, it can be failing.
