🔧 ANOTHER DIAGNOSTIC SUCCESS FOR C.A.R.S.! 🚐

Citroën Relay 3.0 HDi – Turbo Pressure Fault Diagnosed & Repaired

We were called out to investigate a turbo pressure problem on this 2014 Citroën Relay.

🔍 Using our professional diagnostic equipment, we investigated the engine ECU fault codes and examined the live data, including turbo pressure readings, actuator positions and EGR operation.

💡 The culprit? A split pipe in the turbo control system!

Rather than jumping to conclusions and condemning an expensive turbocharger, we followed the evidence and identified the damaged pipe.

✅ Fault identified
✅ Damaged pipe replaced
✅ Road test completed successfully
✅ Vehicle running perfectly!

This is exactly why accurate diagnostics matter. A relatively small pipe failure can cause problems that might otherwise lead to unnecessary and expensive component replacements.

At C.A.R.S. – Car Alarm & Radio Services, we specialise in mobile auto electrical diagnostics and wiring fault-finding across Swindon, Wiltshire and Gloucestershire.

🚗⚡ MECHANIC OR AUTO ELECTRICIAN — DO YOU KNOW THE DIFFERENCE?

We regularly see people on Facebook looking for a mobile mechanic when their car has an electrical fault.

A flat battery, warning lights, a non-starting vehicle or a communication fault may need specialist electrical diagnosis rather than a mechanical repair.

🔧 Ask for the right specialist.

At C.A.R.S., we specialise in mobile auto electrical diagnostics and fault-finding, helping identify the actual cause rather than simply guessing which parts to replace.

📍 Covering Swindon, Wiltshire & Gloucestershire.

🔋 VW CADDY PARASITIC BATTERY DRAIN — FAULT FOUND IN UNDER AN HOUR! 🔧

Another result for C.A.R.S. Mobile Auto Electrical Specialists! 🚐

We were called out to a 2012 VW Caddy suffering from a parasitic battery drain.

The customer had previously paid another auto electrician £350 after they spent an entire day on the vehicle, but unfortunately the fault still hadn’t been found.

We attended, carried out our own systematic fault-finding and, within an hour, traced the problem to a faulty alternator. ✅

No guesswork. No unnecessary parts swapping. Just proper automotive electrical diagnosis to identify the cause of the problem.

⭐ Here’s what our customer Robbie had to say:

“Great service my Mark. He managed to come out the same week I called with the problem and diagnose a faulty alternator with in the hour. Ran me through the whole process as he work. Great stuff. Highly recommended.”

Thank you, Robbie, for taking the time to leave us such a fantastic five-star review. It’s very much appreciated!
