2018 Range Rover Evoque Check-Engine Diagnostics & Repair

2018 Range Rover Evoque driving down the road | Euro Auto Tech & Smog

Before this Evoque made its way into the shop, the owner was dealing with the kind of uncertainty no driver enjoys — a glowing check-engine light, multiple fault codes, and another shop pointing toward an expensive fuel-pump replacement. The SUV wasn’t idling right, felt off, and was clearly asking for help, but the real cause wasn’t yet clear.


At Euro Auto Tech & Smog, we walked the owner through a straightforward diagnostic plan.


  • First, we verified fuel pressure and confirmed the pump wasn’t the issue.
  • Next, we traced the lean-condition and idle codes to a failed PCV Valve/Engine Oil Separator — a common vacuum-leak problem on Evoques.
  • Finally, we tracked the remaining codes to coolant intrusion inside the water-pump solenoid and replaced the water pump, followed by a complete coolant flush and refill.


By the time the work was done, the Evoque left La Mesa running the way it should: smooth idle, correct fuel trims, and no warning lights in sight. Just reliable performance and the peace of mind that comes with fixing the real problem — not the guessed one. The project photo shows the Evoque back in clean, confident shape, matching the renewed health under the hood.



If these issues had gone unchecked, the owner would have faced worsening drivability, possible overheating, and a much pricier repair down the road — exactly what they hoped to avoid.


Imagine getting your own vehicle back to feeling new again, without the stress of unnecessary repairs. Reach out to Euro Auto Tech & Smog, and let’s get your car running the way it was meant to.
