Problems with e85 Z4

[Silver_Z]

Sorry. I believe there are threads with same topic, but however the search feature does not allow me to search for Z4. And having one thru pages with no info, is killing my eyes.

Anyway, I am looking at buying a used Z4 2.5i, and would appreciate information of common problems I will expect from this car.

Thanks in advance.

Touch wood, but my used Z4 (slightly over 3 yrs old) has not given me any problems yet, after a month of ownership.

Get your used car inspected at an independent workshop (I went to one of the site sponsors here) before buying, and make sure your deposit is refundable should the workshop identify ANY problems that you choose not to accept.

Hope to see you around with the Z4.

Thanks guys!

Roof and Vanos seal only? hmm...

Vanos seal problem only affects the Z4? The M54 or N52, or all Vanos engine?

Re: Problems with e85 Z4

Is yours a SMG 1 model? Watch out for SMG valve and pump issues (i.e. leakages)

Chassis creaking noises may be apparent for older models. Nothing music and drop top can't solve.

Sticky steering wheel issues (refer to http://www.bmw-sg.com/forums/help-whats-happening-my-bmw/5085-heat-related-steering-issue-z4.html) Google this as well.

These are the general major issues to watch out for - engine is usually not problematic.

Re: Problems with e85 Z4

No SMG. Just a normal 2.5 facelift model.

Can the automatic top be controlled by the key remote?

How many keys should I expect?

And are they normal looking keys or special keys(retractable, flip, etc)?

Re: Problems with e85 Z4

I had problems with my soft top. Recently fixed it. The car's going to 7years and some parts will definitely wear and tear. Fixed coolant leak and replaced the lower arm bushings too.

If i'm not wrong Z4 facelift fixed the soft top issue..
In all, i really love the Z4 and it has been a really awesome ride. It does not go out of style at all! You can never go wrong!!

Good luck!


PS: The only issue i had is that the car is going 7years and COE prices ain't going down. Time to change

Re: Problems with e85 Z4

Thanks cupholders!

What happen to the top? Was it the motor? I used to have the Del Sol, and the motor for the top broke. Kah Motors quoted me $4k to replace the entire assembly. But from the sound of it, the motor was running, just that probably 1 of the gears in it broke. however they do not replace the little parts in it and require to replace the whole system. -.-"

Coolant leak require a change of the radiator? My current car has the radiator replaced due to crack, and it is supposed to be a common problem. >.<

Bushings are normal wear and tears right? cost a couple of hundreds? I did that once on my E36.

Should still be the standard non-retractable key...

The soft top can be remotely opened by the key, but cannot be closed the same way. This was apparently a safety feature, but I understand the E89's hard-top can be both opened and closed remotely by the key!

There are however aftermarket solutions offered by GapTech and Reinhold Engineering. I went with the former and it works as advertised - one-touch opening and closing of roof via remote.

Hi Privi,

understand your concern of purchasing an used car......i think is pretty straight forward as used car or slightly older ride the wear and tear are unavoidable unless previous owner has changed those wear and tear parts...........the mileage is important as well when looking for a used ride, very much also depend on the tender loving care given to the ride by the previous owner whether he/she maintain his car well enough plus driving style of the previous owner............

hope that helps.............................don't flame me........
happy searching for your 730i...
cheers

Rooftop Repair :
Motor hydraulics and the Arm hydraulic oil was leaking
Total Cost of repair: $2800... and it's still undergoing repair.. Can't seem to fix the problem. Boss quoted that parts for the E85 is very difficult to find nowadays.

Coolant Leak:
Coolant leaked all over the floor, Like urine. Super embarrassing when it happened in School... Found that the container holding the coolant had a hole, Rubber hose wear and tear too.
Total cost of repair: $800, inclusive of Towing.



Hope this helps.
