Track Day Power Steering Issues
I spent last weekend instructing/driving with the Lotus Club @ Denver's new track, High Plains Raceway.
Between taking students out, and driving my own sessions, my power steering fluid boiled over. Although I never lost any steering, there is a rather large mess of boiled over fluid in my engine bay. Keep in mind, my car was in complete OEM form, with the exception of an Eisenmann muffler.
I have read this has been a common problem with the e9x m3's being pushed at the track. Even the instructors at BMW Advanced M School have admitted to the problem.
From my analysis, it seems that the power steering reservoir is located too close to the headers, causing the extreme heat levels.
Tomorrow I will be dropping the car off at a local dealer and will be leaving a letter for a BMWNA representative to read and address the problem.
I will keep everyone updated as it develops.
