Workshop Update: Renault Clio / Meglio Track Car Build
In the workshop this week we had a customer’s part-built Renault Clio / Meglio track project in for a few outstanding issues.
The customer reported:
1. Airbag warning light illuminated
2. Excessive cranking before starting
3. Damaged coil pack connectors
Our Work:
1. Airbag System & Dash Faults
We connected Renault CLIP dealer diagnostics. As this is now a stripped-out track car, several removed systems were still active in the ECU and causing faults. We professionally coded out the deleted items to suit its new track use. Result: no warning lights and a clear dashboard.
2. Coil Pack Wiring
The existing coil pack plugs and wiring were in poor condition and had all failed. We removed the damaged wiring and plugs and supplied and fitted our own in-house coil pack repair kit. All joints were soldered, sealed and finished in motorsport-grade heat proof tape for reliability under track conditions.
3. Poor Starting / Long Cranking
To start, we brought the engine up to temperature and carried out a compression test. All four cylinders returned a healthy and consistent reading of around 160psi, confirming a good base engine.
With that confirmed, we moved to live data diagnostics. We found the intake air temperature sensor was reading a minus figure, which was causing a fuelling miscalculation on start-up. Interestingly, it had not logged a fault code or triggered an EML.
We supplied and fitted a good used replacement sensor, which then correctly read just above ambient outside temperature.
We then tested the start-up from cold, from 50 degrees and from fully warm. Cranking time to start was dramatically improved across all temperature ranges.
The car is now complete and was collected by the customer on his trailer, ready for him to continue his build and get out on track.
