Pinpointing a Hidden Battery Drain: Why Proper Diagnostics Matter
When a customer returned after months of frustration with a persistent battery drain, they had already spent £200 on a replacement battery—yet the problem persisted. Our team carried out a comprehensive diagnostic assessment, which involved stripping sections of the dashboard to investigate further. The culprit turned out to be a concealed GPS tracker behind the instrument cluster, continuously drawing power even when the van was parked.
The diagnostic process, priced at £120 + VAT, ultimately revealed what guesswork could not. Unfortunately, by the time the issue was found, the customer had spent nearly £400 and was facing another battery replacement. This case underscored the importance of expert diagnostics over trial-and-error, saving both time and money in the long run.
- Key Benefit: Enhanced vehicle reliability through accurate fault finding.
