Seat Alhambra Cold Start Problem

I had similar hard starting and rough idle issues with my Alhambra. It was quite noticeable, especially on cold mornings. Have you checked your fuel injection system? Perhaps a fuel injection cleaner might help initially.

Did you experience the same poor engine running only during the cold start phase? What was the final diagnosis?

Yes, the rough idle and hard starting were definitely worse when the engine was cold. Eventually, the dealer confirmed a defective injection valve. I'd recommend a visit to a workshop for a proper diagnosis. They can perform an injector test to confirm.

Confirmed the injector fault with an injector test. Replaced the faulty injector. Total bill 515€. Runs like new now. Thanks for the insight.
