"ABSOLUTELY BRILLIANT! Would 100% recommend Doctor Carbon. Andrew and Leo?... knowledgeable... polite, professional, assuring and most importantly a man who clearly knows his stuff. Had an issue with my car's DPF (engine check - dpf - coil plug lights + car in limp mode). I contacted Doctor Carbon and was immediately put at ease by the engineer who arranged to have the car checked and fixed next day... and true to his word, he did effortlessly. Thank you ever so much".
