Their DQ track interfered with my onboard computer

This is an extremely worrying issue. <br> We have tried to solve the problems that the DQ track affected on my BMW 750i for months until the last thing we did was reinstall the DQ track and all the issues were resolved. <br> We realised that the DQ track was installed incorrectly and was connected to the wrong power rail of the power system which was forcing control units into sleep mode after sensing power draw after after car was off.<br> I have brought this complaint to discovery and they are not responding. <br> <br> Be warned! I forked out more than R16k to solve this problem. DQ track installation done incorrectly may be the cause of faults on your on board computer. Some cars are complicated and require competent installers.
