Our clients and their experience

  • I had a great experience of cooperation with the lads. They quickly agreed on everything and arranged for the new injectors to be sent, so I had everything in hand very fast and was able to fix my car in a very short time. Also received Surcharges refund when send my old injectors back (thanks Michael!). My best recommendations to these professionals!

  • Had an intermittent fault on my car, Diesel Engineering tested the injectors & found a fault on them & replaced all four. I was very impressed with the way they put a cover on the seat & drivers floor well to keep them clean and the price was reasonable for parts & labour.
