640d m sport gran coupe drivetrain warning

Recommended Posts

Sorry if this has been covered already I could not find it. I have a 640d m sport 2014 which has covered 40k. I get a drivetrain warning randomly which then tells me to drive moderately. The weird thing is it is not all the time and after 30 mins disappears, can anyone shed light? I had the egr recall checked and pressure tested it was fine. Thanks in advance

First port of call, you need the gearbox codes read to know if it is actually a gearbox issue or something else. A ZF agent or good Independent with Autologic software a BMW Dealer or Specialist with dedicated software.will be able to read all Gearbox functions, at 40k a gearbox service is almost due so consider that also.

It could be as simple as a sensor not reading intermittently or a software upgrade without the codes it is a guess which could end up with £££ and parts being thrown at the problem.

Quick update, had the oil and filter changed and now 2 months no warning no issues.
