Well to recap , when i got wagon misfiring steve you said icm problem ... Spot on done ! Now
passing gear and take off are very poor!!! Had code on trans syst about brake switch fault 000526 on Snap on scanner .cleared.airbag lite on after start up. gonna check trans fluid level, better still do fluid and filter change. I reviewed haynes manual, it said it may be malfunction in trans module
On the gear display on the dashboard, is there are a red box lit up around all the numbers? Or is just one number highlighted? If it's all lit up, then your transmission is in limp mode and it won't downshift because you only have 4th.
Many Automatic Transmission Control Modules will show a DTC 00526 or 17087 that indicates a faulty brake light switch. This can be ignored and will not appear if you press the brakes once before checking for Fault Codes.
I've run into that code on several auto trans Passats.
