🔧 SKODA SUPERB | EA888.3 WATER PUMP & THERMOSTAT REPLACEMENT 🔧

Another Skoda Superb in at JCE Performance for one of the most common issues found on the EA888 Gen 3 engine!

💧 Water pump & thermostat housing replacement

These engines are notorious for coolant leaks from the water pump and thermostat assembly, often caused by deterioration of the plastic housing and seals.

Common symptoms include:
💧 Coolant loss
⚠️ Low coolant warnings
🌡️ Coolant leaks around the engine
🔧 Visible coolant residue beneath the inlet manifold

With the faulty assembly replaced and cooling system checked, this Superb is ready to hit the road again! ✅

🔧 BMW M235i – EPS Steering Fault Diagnosed & Repaired! 🐀⚡

We’ve had this BMW M235i in the workshop over the last couple of days with an electronic power steering fault.

Initially, it looked like a straightforward steering rack replacement due to a suspected faulty EPS unit.

However, after carrying out further electrical testing and in-depth diagnostics, we managed to pinpoint the real cause of the problem! 🔍

🐀 Rodent damage!

Rodents had managed to get into the wiring loom and chew through all 3 communication wires running from one of the EPS multiplugs, resulting in a complete loss of communication with the steering rack.

✅ Faulty wiring located
✅ Damaged wiring repaired
✅ EPS communication restored
✅ Power steering fully operational

No replacement steering rack needed! 💪

A perfect example of why proper diagnostics are so important before throwing expensive parts at a vehicle!

Another one diagnosed, repaired and back on the road! 🔥
