year?

 

2016 registration plate

 

With that year you should either do it yourself with a direct connected to the OBDII diagnostic connecter a fair quality scan tool (no blue tooth scanning tools) and retrieve the information that "WILL" be there for you to properly start a trouble shooting solving tree. My advice based on your responses would be find a shop in GB that has a currently Certified (at least in the last 3-5 years) Diagnostic Technician employed to do the scanning and give an assessment for service. Then you can decide if you can do the service work and have the correct needed tools or have the shop service it.

 

Thank you advice appreciated

 

Sorry I had to bail before I finished my respons to you because we got 6 vehicles 2 towed into the shop all at one time.
A quality shop diagnostic time for this is 1 hour labor and should not take any more then that if they know what they are doing. Do let them them claim they need more time to find the problem.
