Interesting. Which relays should I be focusing on exactly? And where are they located? I'm reasonably handy with vehicle electronics, but could use a pointer.

In my case, it was the main relay supplying power to the engine control unit. Perhaps it is best to consult a workshop.

The engine control unit issue on my Alhambra was a faulty main relay, as suspected. The repair cost 120€ thanks for the advice. I appreciate it.

I have a Seat Alhambra as well. I experienced something similar some time ago. Did you check the relays related to the engine control system? It could be a simple fix.
