Mañana pretty much sums up the Halfords Auto Centre at Farnborough, Hampshire who had my car for all of Friday 4th January 2019 and the morning of Saturday 5th January 2019. Snotty customer service, criticising spark plugs as bought from their Halfords shop as being the wrong make and confirmed that they are correct according to the Haynes manual for my car, promptly replacing the spark plugs with the car’s manufacturers spark plugs at what is the correct gap for my car make and model. Halfords Auto Centre at Farnborough Hampshire managed to perform a diagnostic test on my car on Friday 4th January lunchtime, but were not able to actually tell me what the fault was or the result of the diagnostic test other than charging £49.99 for the task, on Saturday 5th January 2019 they allegedly intended to take the manifold off my car to look at something but did not actually do that preferring to put the car to one side until another time maybe another day. So having been charged for another lot of spark plugs and a diagnostic test, we’re still none the wiser as to what the fault is or what could be done. Safer to retrieve my car and take it elsewhere for a professional garage to look at the car with a view to repair the fault as Halfords Auto Centre Farnborough Hampshire are clueless.
