It started with a noise no Jaguar owner ever wants to hear—a deep, rhythmic knock from the depths of the 2.0-litre Ingenium diesel. My 2017 Jaguar XE, which had been a steadfast companion on motorway commutes, suddenly sounded like it was operating a miniature jackhammer under the bonnet. After a trip to my local independent specialist, the diagnosis was grim: bottom end failure. The conversation quickly turned from repair costs to the reality of a replacement Jaguar XE engine. Initially, my heart sank. I envisioned a bill that would exceed the car’s current market value, forcing me into the stressful hunt for a new vehicle in a volatile market. However, I decided to pause and explore every avenue before making that final call. The world of engine supply and fitting felt like a daunting labyrinth of jargon, varying prices, and questions about reliability. I needed to cut through the noise and find a solution that wouldn’t compromise my car’s performance or my bank balance.
