I can only presume that based on the colour of the old fluid, this was original. Here is a photo of the old fluid compared to the new fluid: I decided to keep driving it for a few days to see if there were any other changes.įortunately, the noise never came back, and still has not come back after over 2 months and 3,000 kms. F**k! I kept driving for about another 10 mins but couldn't get it to do it again. But about 2 mins into the road as I was driving up a slight incline the noise came back. All seemed fine it was shifting smoother and felt a lot better. I went to his shop and took it for a spin myself. He called me and said he'd taken it for a test drive and the issue was not fixed. Jon at Auto 38 completed the trans flush and adaption reset. Was this a failing transmission that would cost nearly double the value of the car to repair? After extensive online research, visits to transmission specialists and phone calls, I was persuaded that a simple transmission fluid flush and filter change could solve my issue. It would do it most often while cruising along the motorway at about 80-100km/h. Knowing of the cost of repairs for these ZF boxes, I was heartbroken. It would last about 2-3 seconds, the revs would drop slightly, and then it would disappear - only to reappear consistently every 10 seconds or so. But about 5 mins into the test drive a spine tingling grinding noise presented itself from under the car. It shifted fine and initially seemed to have no issues. After getting out onto the road I realised how loud the road noise was (the tyres were years old) getting back in my 530i afterwards felt like stepping into a sound insulated haven.īut most worryingly was the transmission. This was solved by the seller kindly replacing the coil packs on cylinders 6, 7 and 8 (where the misfire codes were). When we first started it it was misfiring and throwing a CEL. The suspension was tight, the power was overwhelming (it pulls like a freight train) and the handling was far more confidence-inspiring than my 530i. I've been in an E39 M5 a couple times, but never a 540i. But most of all, it showed me how awesome these 540i's are. The test drive highlighted a few things (issues).
