Hi, been a lurker for sometime now, and I just got this:
2007 Black Sapphire Z4 M Coupe
46,xxx miles
I got it from Carmax and they gave me a 5 day return policy, no questions asked. I also got their 60month warranty (first time buying a warranty).
I have some questions about the car (I did look through the forums) but still not sure. So if I am asking these questions in the wrong place, apologies.
1. When I turn the car at slow speeds, steering wheel all the way, the rear makes a noise. *I heard this could be the LSD and the fluid related to it.
2. The engine makes a sound which I am not sure if normal for the engine, it doesn't do it in neutral. This is my biggest concern, also, my previous car was a e46 330ci and it didn't make this noise (I know different engines).
I took it to a BMW mechanic(non-dealer) and he told me the following:
Differential Clutch Noisy, slippery clutch (said this was related to slow turning noise)
Rear shocks noisy, new tower mounts
He plugged in his computer and it said the following:
Outside temp sensor
5DF4 Battery voltage too low; open circuit
5E1F Control unit: incorrect vin; calibration required
5E16 message, IKE (610, 613, or 615)
oil condition censor, communication
Mixture control
mixture control 2
He also told me to have the check the VANOS...
So, I am happy to finally own something I wanted for a long time. I don't want to return it.
Thank you for any responses and I am happy to have joined the rest of you Z4 enthusiasts.
