Instrument cluster 5/5

After numerous random problems with engine malfunction and immobiliser activation and having to call the RAC I heard about ECU testing and read reviews so I thought i would give them a try, took the instrument cluster out and sent for repair, had the unit back in 5 days re-fitted and problems have gone, wouldn’t hesitate to recommend and would definitely use again should the need arise, thank you very much 👍🏻
