🚗 **Nissan Qashqai – Engine Management Light & Rough Running Diagnosis** 🔧

This Nissan Qashqai arrived at **CL Autos NW Ltd** with the engine management light illuminated and a noticeable misfire.

From the moment it arrived, it was clear the engine wasn't firing on all four cylinders. Our diagnostic process quickly uncovered the cause:

🔍 **Our findings:**
✅ No. 2 spark plug removed – ceramic insulation had broken up.
✅ Compression test confirmed low compression on cylinder No. 2.
✅ Borescope inspection revealed impact marks on the piston crown.
✅ Further inspection showed an exhaust valve with a chunk missing.

Unfortunately, the broken spark plug insulation had caused significant internal engine damage.

At **CL Autos NW Ltd**, we don't guess – we diagnose. Using the correct diagnostic equipment and a methodical approach allows us to identify faults accurately, saving customers unnecessary expense and getting to the root cause quickly.

🔧 Oil Leak Investigation & Repair – Done Properly 🔧

This Citroën Berlingo 1.6 BlueHDi 8V arrived with a persistent oil leak after being diagnosed elsewhere as requiring sump repairs.

After carrying out a thorough inspection, we found the sump wasn't leaking at all. The actual cause was a warped and leaking rocker cover.

While carrying out the repair, we also discovered:
❌ Missing bolts
❌ Bolts fitted in incorrect locations
❌ A badly fitted boost pipe seal

All issues were rectified, the rocker cover was replaced, and every component was reassembled using the correct manufacturer procedures and torque specifications.

✅ Accurate diagnosis
✅ Correct repair first time
✅ Manufacturer specifications followed throughout
✅ Quality workmanship with no shortcuts

A great example of why proper diagnosis is just as important as the repair itself.

Volkswagen Golf 2.0 TDI – Timing Belt & Fault Diagnosis Completed 🔧

This Volkswagen Golf 2.0 TDI came into the workshop for a timing belt kit and water pump replacement, along with an ongoing fault that another garage had been unable to resolve.

✅ Genuine timing belt kit fitted
✅ Genuine water pump installed
✅ Genuine timing tools used throughout the job

The customer had already spent money replacing both auxiliary water pumps at another garage, but the fault was still present.

After carrying out a thorough diagnostic investigation, we traced the issue to a wiring harness that had been rubbing through and causing an intermittent electrical fault. Once the damaged wiring was located and repaired, the fault was completely rectified.

This is a perfect example of why accurate diagnostics are so important. Replacing parts without identifying the root cause can become expensive very quickly.

At our workshop, we focus on finding the fault, not just fitting parts.

📍 Professional diagnostics
📍 Genuine parts where required
📍 Manufacturer-correct tooling
📍 Quality repairs you can trust

If your vehicle has a fault that nobody seems able to solve, get in touch—we're always happy to help.
