Pre Course Learning

We recommend Diagnostic Assistance software as a pre-course learning resouce. Reviewing the content relevant to the course you attend will make sure you get the best from your training time in our training workshop. We’ll also provide you with other essential pre-course information when you book your place.


The hands-on training takes place in our workshop. The course will cover the key conecpts of the subject matter. You will work on suitable vehicles using a range of relevant tools and equipment. This will mean that you can put your new skills to work as soon as you get back to your workshop.

Post Course Support

When you get back to work you’ll be busy putting into practice your new skills. We recognise that you may have questions and queries as you develop your practical skills. We will help you through this ‘on-the-job-learning’ phase by providing you with access to our technical support forum where you can ask your instructor and course colleagues questions on your new found skills.

Independent Training Organisation with 30 years experience

Technical Topics have 30 years experience in technical training and education. We have been running independent training since the late 1980’s. We are very proud of this heritage and it makes a real difference to the quality of our training.

We are an IMI Approved training centre which means we offer certified courses which meat National Occupation Standards and provide a nationally recognised qualification at Level 2, 3 and 4.

We really appreciate the continued support our customers give us, and we will continue to support our customers in their professional and personal development. We’re no ‘Flash-In-The-Pan’ business’. Our long history is a great indicator that we’ll be here for many years to come, offering great training, support, guidance & friendship.

We are fully and fiercely independent and are not tied to a single parts manufacturer, parts distributor, equipment supplier or vehicle manufacturer. Our business and our way, like your’s, is fully independent.

What can you expect of our training ?

Hybrid and EV We sent 2 of our guys for training on Hybrid and electric vehicles…. Both came back with complete confidence and the ability to carry out systems tests and diagnosis safely which was one of our main concerns. Great Job!!

First course I did was The boot camp which was amazing. I went back to my garage a different tech. I was so impressed I did the eeprom training yesterday and I am also booked on next months Odis training. If you are in need of some quality training in a friendly environment James Dillon training is second to none !

I attended the diagnostic boot camp as an absolute novice to world of electrical diagnosis. The things I learnt where phenomenal. It really changed my career from the first Monday after course in work shop.

Recommend to anyone

Diagnostic Bootcamp I recently attended the 5 day diagnostic boot camp, and can’t recommend it enough. If you’re thinking “how can I spare 5 days from the workshop” I say, how can you afford not to. From reinforcing the basics, to advanced problem solving, it’s all covered, at your pace. I guarantee you will leave a better technician.

Been on 2 courses with James now, absolutely brilliant. Would recommend to anyone looking to take their automotive career to the next level.
Matt Sanderson

Owner, DMS Auto Services

I have done a few courses with James at Tech Topics. From basic fault finding , Oscilliscope, Advanced Oscilliscope to EEPROM Coding & Programming. Also I have commissioned and worked closely with James in him delivering 3 two day sessions for a group of fellow Landrover Specialists. James always delivers in a humourous and interesting manner, with real life anecdotes and straight to the point teaching. I thoroughly recommend James as an industry leader in Motor Vehicle Diagnostic Training.

Owner, Dinedor Cross Garage

Iv attended a number of courses at technical topics and could not recommend james enough. I always leave with more knowledge and understanding with more confidence in making diagnostic decisions. The training is put straight to work first day back at the workshop.Iv been traveling over from Northern Ireland for training for over 5 years and will continue to do so.

I’ve done several of James’s courses and have benefited massively. James describes things in an easily understandable way and is always very enthusiastic. James is always willing to help even after you’ve attended a course or bought equipment via him. I also find James’s diagnostic assistance software very useful to refer to when needed and a great training resource for employees.

Owner, Erme Vally Autos

Went on the ODIS training at TechTopics. I must say the training was extremely thorough, and very well delivered! A friendly and relaxed place to learn. James’ knowledge is extensive and I found nothing was too much trouble for him to help you! I have since had issues when changing hardware on the ODIS system. James has gone above and beyond the call of duty to resolve my issues! Which I must add were not a 5 minute fix!! Highly recommended and I hope to go on the boot camp course very soon.
Stuart Lawson

Excellent training courses, delivered in an easy to understand and enjoyable style by one of the best diagnosticians in the industry. Small groups and practical sessions make it a must for anyone looking to learn and develop their knowledge and diagnostic skills. Highly recommended. Check out James’s range of bulletins and books too that are available and designed to help you in your own workshops.
