    Seen on the German forum.... any ideas ?

    Seen on Zroadster.com........Does anyone recognize this ? Anyone with the same kind of problem ? The Z8 is build in 2000 and has driven 30000 kilometers.

    If it is what I think it is, aluminum oxide, I am happy to say he last time I saw that was more than thirty years ago on my Dad's all aluminum Masterati Mistral. It is harder to cure than steel (iron oxide) rust because it eats inwards into the metal, digging itself in like a virus, unlike rust which initially 'blooms' only on the surface. If you see this starting anywhere on your car I would contact BMW and ask to be sent to one of their specialist Aluminum Repair Centers right away.

    i do not believe that is actually a Z8 and is...

    a picture of the Z3, which indeed would make it iron oxide rust. Macfly, have you ever heard of that happening to any of the Z8's? Has Juergen mentioned it... sure seems that if there was even one Z8 with that going on, he would be all over that.

    What makes me think it is not a Z8 is the lines of the pictured body panels do not seem to match any of the junction areas of the Z8 that are aluminum (hood and front fender and rear fenders and trunk as there is no way those pics represent the door of a Z8).

    The junction here looks like that of the trunk/fender area of the Z3.

    I tried to find the same post on Zroadster.com but I do not speak/read German so I wonder if there are more pictures of that actual car in question as that would be most helpful.

    looking at the picture more, the only place on the Z8 that that particular junction could be (based on the shape) would be the junction of the trunk left driver fender area at the tail light -- considering the chrome accents with the neon tail light would be visible too, I doubt this pic is from a Z8.

    I haven't heard of any Z8 body panel issues, I think that the processes used in the construction of our car will keep all but the saltiest winter drivers in tip top shape for all our days - and I think you're right about this not being a Z8 panel, I also can't figure out which junction it could be if it was.

    Jeff, you can read the whole story over here:

    p.s.
    I see no reason not to believe that this is a Z8.

    It is a door panel of a Z8 for sure!

    Dear Jeff, dear Andrew, sorry to disappoint you!

    The picture is real and shows the door panel of a Z8 for sure. You will find the area illustrated where this problem occurred on the picture below. I was surprised to see rust on the aluminium door panel on this car and started to investigate this problem. So far I found three cars with exactly the same problem. All three cars are located in Germany, are pre owned and I was not able to get a full report on the history of the cars, which makes it very difficult to answer the question ?why? this occurs.

    Two of the three cars were not used and treated, lets say, like a collectors car. They were and will be used as a daily driver, even in the winter and on salty roads. To give you a picture, these two cars live the life of unloved children and are stored in damp caves. The storage of the cars is very important because humidity could cause heavy damages.

    A simple photo on a board does not give the entire picture of a car?

    For example! Would you be surprised if a Z8 which was used for the BMW Driving Experience by several unnamed users, finally sold on Ebay, will in return trouble the current owner with VANOS Problems? I think not!

    On the other hand all Z8 owners should be aware of the fact that each single Z8 was out on a test drive in Munich (Germany) under real traffic and weather conditions after the car was assembled. After the test drive the cars were prepared (washing, polishing etc.) for the transport to the dealerships all over the planet.

    So if the Z8 was produced in the winter period and there were bad weather conditions, the Z8 definitely saw salty roads!

    Thanks for the full story J?rgen, and I'm very happy to say my car was a July build, so hopefully it missed both rain and salt!

    Knowing the corrosive effect of road salt on my cars and motorbikes growing up in the UK, I'm not too surprised to see a little oxidization on a car that has lived through seven winters unloved. When I was about twenty two I bought a ten year old Volvo station wagon as my first equipment hauler. It had been used as a daily driver by a vet in the country, where the salt sits for months. I thought it would last two or three years, but as I leant first hand, once oxidization really sets in it works fast, that car literally feel apart in the space of a year!

    I stand corrected!

    Still , this is very concerning as even an "unloved" Z8, should still not produce this type of oxidation in a 7 year span from normal highway use, salt or not, especially, given the current state of paint / anti-rust technology.

    I am interested to know what is determined to be the underlying cause -- maybe a manufacturing defect? (Oh NO!)

    I am happy though that my Z8 had a build date of September 2002 so I guess mine was away from those salty roads in Germany but alas, I do have them in Oklahoma and have had to drive mine in those conditions, so far, no oxidation -- at least none visible so I will definitely be on the look out over time!!

    Hi again after a long absence.
    I don`t think the salty roads are the cause. Because they should be washed and cleaned completely after the test drive. The main reason should be the humidity. Either storing the car in a humid place like underground garages or living in a place with a very humid weather.
    Check this thread it`s a common issue with aluminum.
