Always a great experience at TTHQ. The knowledge that is available to tap into is extremely deep.
Dec Roberts
I have attended the VW EV Specialist course which I found it extremely interesting and quite fruitful in regard to specific and explicit knowledge gaining. It will sure help me in general on my EV garage work.
CHRISTOS KOURTELLARIS
Really enjoyed the jumping in at deep end this time, I found less classroom time and more work shop worked for me better I understand this isn’t case for everyone but the higher level stuff we learnt was brill, thanks again!
Frazer wood
Great course, so much information and just delivered in the right way. Hope to be on a few more courses.
Chris Williams
Great course and well presented by James and assistant Kev got back to work on Saturday morning with a Vw Passat waiting and bang p20ee so got stuck in thanks again.
Gavin Ashford
If you want to do EV training, I wouldn’t go anywhere else. The workshop has options of hybrid and EV cars. As well as off car components and test equipment to let you get plenty of hands on training. Plus it has classrooms to understand theory. Tech topics doesn’t only teach us, they are diagnosing customers cars with real problems. I have seen teachers from colleges coming hear to learn the subject. This is the ideal course to get a very good understanding on hybrid or EV cars. Can’t recommend it enough.
Matt Brereton
Overall the course was fantastic, and covered a lot of content that i otherwise may have struggled to understand. I now feel more confident tackling situations at work that require a level of mechanical understanding.
Bradley Hoult
Outstanding Quality and Value is given throughout! Thank you TTHQ
Luke Yoxall
Iv learned a great deal and also recapped on procedures that Iv possibly let slack a bit. I feel much more confident in a few aspects, predominantly in customer preparation and explanation. Thanks guys! I look forward to using what I have learned and any other courses I can attend. ??
Katie-Mae Taylor
Amazing thought provoking course! Have started the implementation of new processes that will reduce the stresses of diagnostic work.
Michael Shaikly
Absolutely fantastic course, great guys and look forward to future courses
Jay
The knowledge and delivery of the course content is second to none. I knew nothing about Eeprom and coding and am more than confident now to dive straight into it back at work.
Peter Thirtle
great course and very well delivered. great content with a healthy blend of practice and theory.
Barry Costello
First time visiting TTHQ2, and first time meeting some of the staff. It was a great experience and such a well thought out and highly equipped workshop. Looking forward to coming back later in the year.
Tom Cockings
A must training course very well presented and totally mind blowing experience .I enjoyed it tremendously have learnt so much about what goes on inside the box highly recommend to anybody wanting to up their game in this very fascinating subject thank you Rob and James for an amazing 2 days can’t recommend this course enough.
Dave Ball
From the enrolment to the e-learning and the assement, TT have always gone the extra mile. For a slightly more mature gentleman, they were patient and explained everything in clear terms. The facilities are really excellent and the knowledge of James and Wilf is second to none. Great value. Hoping to be back very soon
Anthony Kitching
The only reason I didn’t tick every box was because the course isn’t over yet! Looking forward to the rest of the journey!
Adam Luckett
Great experience, extremely knowledgeable instructions who are truly passionate about what they do. Looking forward to the rest of the course.
Kevin Street
Always excited to attend a course at TTHQ. Always feel I’ve learned loads and filled in gaps of my knowledge on each subject. Resulting in increased confidence when returning to the workshop. 4 rights is the only way. Look forward to my next course.
Steven Mcleod
I’ve done the diag tech course and I’m just over halfway through the master tech programme and I’ve enjoyed every minute of both courses, there no doubt that I’ve become a better technician through attending and i can but thank you for the efforts and coaching you’ve invested in me over this time, thank you. As for course content its remarkable to re learn about things that I previously thought that i considered i knew about already, to a level that really far surpassed what i was expecting and again to have that in depth knowledge makes hard days a breeze.
Alex Scott
I had a very basic understanding of Adblue systems and attended the course to improve my knowledge and diagnostic process. This was my second training course at TTHQ and again was so impressed with the information and course content. Their unique approach to problem solving and the ability to pass that on is first class.
Stuart Hateley
Awesome as always the golden hour course has helped me with my process no end thank you
Jodie Phillips
I regard James as the best technical trainer in the UK, his laid back calm approach gives you the confidence to ask questions. Looking forward to putting the newly learned process into practice ! Thanks again James.
Dave Harney
The welcoming and unrivalled training was a joy to do presented in a professional and light hearted way a real really enjoyed the learning experience feel much more confident in my approach and plan in tackling diagnostic jobs now thanks James and the team .
Dave Ball
Great Course with lots of content covered , excited to put the plan into action , looking forward to further courses in the future
Robbie Nelson
Really helpful to see the equipment you wouldn’t normally come across on an ev and its operation
Andrew Rees
Brilliant training course. Broke down the diagnosis process to simplify the fault. Came out of the course lit up like a Christmas tree with all the light bulb moments i was having through the two days listening to James
Lee Pritchard
” Thanks James and the team for a great couple of days. As always a very enlightening course by James. You may think you know a subject but as always seems to be the case, you go home looking at things in a very different way. Thanks James and the team for a great couple of days.”
Simon Ward
Great course very informative!
Michael Shaikly
Fantastic, brilliant courses, dealt with the root causes of high NOX emissions not just the SCR side and it’s associated faults. We also had a customer vehicle which was under going repair which greatly enhanced the experience. James delivered this course with his usual excellent style which really helps to underpin the information he’s teaching. Thanks James and all staff at Technical Topics
Simon Carter
Very good course, very good info and as usual James was on form.
Andy mearns
Excellent training
Michael Shaikly
Very good information about all systems that were covered, practical demos were excellent on showing us how to carry out many tests but more importantly what we should be seeing etc
Jon Eva
In depth knowledge of AdBlue and awesome test methods Honestly one of the best courses I have been on at TTHQ. In depth knowledge and awesome test methods.
Grant Watkins
Gives you a full understanding of how AdBlue Systems Work This course was one that was really needed as it gives you a full understanding of how all the systems operate, its described in a clear way that you can put straight into practice. The course structure is very good and you also get the simple pitfalls to avoid and gives you diagnostic path to get it right. James and his team pass on all the expertise so we can become better technicians and without this great training environment i would not be able to make the big diagnosis we now make on a daily basis. Keep doing what your doing as its what this trade needs constantly to keep up to date.
Adrian Woodhouse
This course takes the mystery out of Adblue, over time I start seeing changes to cars that have happened after I left the main dealers. Definitely a good idea to know why something like this is fitted, how it works and how to diagnose. When customers ask me what does it do, I can now tell them a bit about it. I also found that this course answers questions to problems I have had in the past. Lots of new knowledge, cheers Matt
Matt Brereton
“Absolutely amazing course this really was! I’ve been on a number of courses now at TT, this (as ever) was second to none. The content, venue, delivery, and course notes were all top drawer! Possibly my favourite course to date. Highly recommended to anyone thinking about enrolling. I’ve used the learned material to fix quite a number of AdBlue/SCR system faults since. This course undeniably made the faults much quicker and more easily solved!”
Stuart Lawson
Diagnostic Bootcamp what an amazing course. James is so knowledge and explains things everyone will understand. Thanks for a great 5 days.
Robert Papps
Highly recommended. Recently went on the Diagnostic Bootcamp and was very impressed. The training style certainly helped me absorb a vast amount of knowledge in 5 days. Even with different skill levels of people on the course I felt everyone came out of it having improved their knowledge and approach to diagnostic work, I certainly did.
Stephen Kennett
A great course to learn about all the new systems and technologies being used on this new EV platform. Being a VAG specialist it definitely gives us a head start as we are starting to see these in for service already. Highly recommend this course.
Ian Whitmore
It was an excellent course which provides a comprehensive idea about VW EV platform
Thanks for the trainer and for all Techtopics team
AMEEN AL-KISWANI
Excellent course with detailed information relating to the VW ID3 Electric Vehicle MEB platform. Rob the tutor was really good in delivering the course and had excellent subject knowledge. Thanks for looking after us for the whole 3 days and also providing lunch, which was excellent.
Paul Griffith
Just back from taking the ADAS course at Tech Topics. As always James and his team are brilliant. There is no such thing as a silly question, never be afraid to ask. If you don`t know the answer, you will when you leave TTHQ. The ADAS course is a must for anyone serious about getting into this field. Having now attended i know which way i`m heading with regard equipment purchase. I now cannot wait to get myself on the EV Bootcamp.
Alan Newman
Excellent ISTA course, very well delivered by Wilf, very informative and left with confidence in using ISTA. I believe TT training to be better and more in depth than any main dealer training I’ve attended.
Craig Sutton
Thank you all so much for a well put together course. Your knowledge is second to none, your training aids were great and I learnt so much.
Kind regards
Matthew Honor
Left today feeling like I can tackle most Nox related issues that come my way, from start to finish of the course I felt it made complex issues explained into segments where it was so easy to get head around. Love the pace of the training also, basic understanding to whole class being able to do complex maths channels on the pico. Last two days made me feel lucky I can call days like these part of my ‘job’. Thanks all.
Frazer Wood
A course that challenges you to change your mindset towards improving your efficiency and reducing your stress in diagnostics. Being in the diagnostics for more than 20 years now I strongly recommend this course especially for the young people who are getting into diagnostics now.
