DPF issues from glowplug control relay and additive – Citroën C4 1.6HDi (2008 – 99,784 miles)

⭐⭐⭐⭐⭐ ‘My 2008 Citroen C4 1.6hdi had the dpf light come on. The local garage cleared it but wasn’t confident it would stay off. They told me to speak to the main dealers. In the end, I just got confused, mainly because neither of them told me what the problem was. Enter Adrian, after having read his website I felt confident that he would diagnose the fault. He arrived promptly and went about his work in a professional and friendly manner. The fault was diagnosed to a relay, he also did a carbon clean, the car is now a totally different car to when I bought it. It’s much quieter and much more responsive as well. Would I recommend Adrian? In a heartbeat every time.’
