Hi Everyone I just purchase a 1999 Volvo C70 for my daughter with 160000 miles, new to this brand, all started with a blown out brake light bulb which I replace, then I did the oil change, tried to reset the service reminder which was not on yet. the car started to drain out the battery. took it to a diagnostic and these are the codes ECM 530D, PO605= TCM0049 apparently the technician estimated $1500.00 in cost to replace the TCM. due to it stayed on while the car is off

Thank you very much for your response.
