I ordered a new battery for my car (mini cooper) as it was showing low charge warning. The fitter arrived on time and replaced the battery. I asked if it req'd coding as most cars with stop/start need this to be done. The fitter said it did not as long as any warning lights go out (he did not plug anything into the car to tell him whether it needed to be reset or not). So it appears that they make the decision themselves and not follow any manufacturer's recommendations. After he left, I refreshed my knowledge of how the system works on these cars and saw that it did need coding as the car will continue to charge the new battery at the same rate as it did for the old degraded one which could adversely affect battery life, economy and the car's electrical components. I made a call to the number on my order and they confirmed that it req'd coding and made an appointment for this to be done. On the day of the appointment I received a call to say they would not be attending and to just drive the car for 15 minutes and it will learn itself that it has a new battery and everything will start to work. As the stop/start began to work they said everything was as it should be and the fitter was right to say it wasn't required. This did not explain the fact that the charging system had not been reset. The fitting information online when you purchase a battery explains that professional fitting is advised as it could cause damage to the vehicle's electrical system if not. This is the only reason I chose to have it fitted. The amount of stress and time spent complaining to people who were not listening was not worth it. After over a week of emails backwards and forwards and receiving the same explanation, I was getting nowhere so I contacted my local Halfords garage and explained to them the trouble I was having to just to get the service that I'd payed for. They fitted me in and got my battery coded in 5 minutes with no problem. I would say that if you need a battery, Do not use tyres on the drive. Go to your local Halfords garage and have it fitted. Tyres on the drive are giving Halfords a bad name. Cars systems could be getting damaged and needing costly repairs as a result of the lack of knowledge about these systems, and you will struggle to prove liability should anything go wrong leaving you with a rather large repair bill. It only takes 1 bad experience to stop you using certain companies and word of mouth goes a long way I will never use these again on the back of their unwillingness to put a job right, and I gave them ample opportunity! Thank you to Halfords garage though for putting it right!
