April 2012: Open day a great success.

After the finishing of a major building refit TAIC held a free training and open day to 73 local motor engineers. The training was on common rail injector diagnostic procedures both theory and active sessions on Delphi, Bosch and Siemens systems. This was presented by Graham Williams BST (Bosch Systems Technician) the workshop manager and all of the TAIC workshop engineers. Day two saw Delphi's leading field engineer Richard Sibley join in with the training on Delphi injectors.

Such was the demand for the training that a second day was added.


The attendees gained valuable knowledge not only in fault diagnostics but also on what is actually inside the units including strip down, repair and testing using both Bosch and Hartridge benches.

Later in the day presentations were given by Delphi Diesel Systems and Bosch UK which included the Diesel particulate filter (DPF) and systems that will soon be fitted to the passenger vehicle.


The open day also gave everyone a chance to see and enquire about the latest diagnostic tools and equipment which were being shown by Delphi and Bosch. Filtration experts were also on hand to demonstrate the need for top class OE standard filters on today's common rail equipped vehicles. All of which can be found on our shop

The management and staff at TAIC would like to thank all of the engineers that attended. The feedback from the day was exciting and we hope to carry on serving franchise and non franchise workshops, factors and distributors. “Friendly staff and well presented training” D Killick St Georges garage.

To keep up with the demand for service and repair of common rail injectors from Delphi and Siemens a new Hartridge Cri-Pc test bench has recently been installed.
Only this test bench is approved by Delphi & Siemens. The PC based testing includes all of the original manufacture test plans.
This way not only are the serviced injectors repaired using only genuine spares but also will function as the vehicle manufacture designed.
This guarantees you a quality product, correct engine operation, lower fuel use and reduced emissions.

specialist Thomas Auto Injection Centre. The program will be available from participating dealers with the official launch at Hillhead 2014.

Quality has to be paramount. This is guaranteed only with the use of  genuine spares and the only Yanmar approved diesel workshop of Thomas Auto Injection Centre.

Bosch Piezo injector testing now available.

With diesel injection systems on a continuous improvement the workshop has to keep up to date with machine investment along side technician training.

To keep pace Thomas Injection Centre have had the Piezo testing capability added to the Bosch 815 common rail test rig

New Common Rail Clean Room Built and Approved by BOSCH UK

Why the need for a Clean Room?

The introduction of modern high-pressure diesel common rail injection systems working at 1600 bar and above creates the need of reorganizing workshop practices.

Tolerances held in these new systems can reach 1μm. Therefore, perfect cleaning must be guaranteed during disassemble and most importantly during set up and reassemble.

Thus, new basic procedures have to be followed during all the process of removal, installation, repair and breakdown investigations in these diesel injection systems.

To meet the new requirements it is essential to create an exclusive area for assembly of pumps & injectors. The clean room is developed in such a way to assist all work procedures stated by Bosch UK & must be approved on inspection by BOSCH.

With the ever increasing work load at Thomas Auto Injection the need for a larger clean room was required and so we have created a new assembly & set up area meeting all of BOSCH stage three repair system.
