We offer a free "While you Wait" Battery, Starter and Alternator Test
Dragon Automotive have both Midtronics and Bosch (the two leading manufacturers) Battery, Starter & Alternator portable test equipment. This means that we are happy to offer a completely FREE while-you-wait test (including printout where applicable). You're under no obligation for repairs either but if you do need a battery or there is a poor reading, we can solve it for you then & there if requested.
We have crumbliss test benches as well as our own modern customised test bench meaning that we can test most alternators accurately to establish what the part is doing. If there is a problem with our alternator, Dragon Automotive offer rebuild services as well as replacement. Whatever the problem, you can rest assured that we're here to help.
When a starter motor sticks on or won't allow turnover, there are answers to get the issue sorted including rebuild and refurbishment or even remanufacture from the original part specifications when necessary. Often necessary with Classic cars, there is light at the end of the tunnel with Dragon Automotive.
Battery Drain issues are normally the problem we have seen mis-diagnosed the most. Using a tried & tested technique, we have never failed to pinpoint the cause (or causes) of a battery drain on any BMW yet.
Typically we make use of in-house developed CAN bus analysers to see what modules are waking up and we use in-house battery current meters (connected in place of the battery) to monitor current usage throughout a period of time. We're set up to tackle this issue, don't waste your cash using someone without the skills or experience.
