Injector Removal Service is our 3rd division that offers mobile assistance in removing and replacing the faulty injectors and glow plugs that are seized or broken. A damaged injector might cause a car to shake, judder, misfire or stall completely when you are out on the road. Most garages can diagnose the problem, but not many offer hydraulic seized injector removal. Our latest hydraulic equipment allows us to do the jobs that others cannot. Therefore, if you have a seized injector issue, we can save you time and £££ from having your engine dismantled and the cylinder head replaced. Find out more on the Injector Removal Service website

What do they say about us?

  • Clement

    Having a small fleet of vans is essential to keep them running without problems every day. OGS Mechanics understood exactly the situation of applying a very fast and efficient way to deal with all the issues. From the office staff to the technicians, thank you all for your help.

  • Stephen Cobb

    I have used OGS Mechanics on a few occasions now and appreciated the quality of their service. Always courteous and friendly,and fair and professional in all the dealings I have had with them. I would recommend them to anyone ..... indeed I have!

  • Waterguys Ltd

    OGS were very professional and experienced. They gave me the correct advice and I left feeling reassured. A quick diagnosis and a temporary repair. I will definitely be using them again to resolve the issue permanently.

  • Conarg Ltd

    Thank you for the great service provided. Thru out the process, we have been kept up to date with pictures and the progress of the works. Would definitely use it again and recommend it to others.

  • DCS Universal Ltd

    We have used OGS Mechanics Ltd for years now and we are completely satisfied with their work which is always done quickly and effectively, and their customer service is amazing. We definitely recommend them.

  • Andrew Spencer

    I have been going to OSG for several years and in all honesty, would not trust any other garage. They are honest reliable and efficient. An organisation that not only takes care of its customers but it’s staff too. If possible I would rate them 10 stars.

Simon Stephenson

After speaking with several garages in NW London one Friday afternoon, none would take delivery from the RAC relay of my broken down ML, an ECU issue and a big car. When I spoke with George and Alex at OGS the difference in customer service and knowledge was almost too good to be true. I'm pleased to report it was 100% true, they were good to their word and very fairly priced and some of the nicest people I've ever meet in the car repair business. Their professionalism and integrity might explain why they're such a busy little workshop, I guarantee you won't be disappointed in the quality of work, their knowledge is off the scale and the price is excellent.
