Problematic 7er

"buy a bmw they said, itll be fun they said!"
haha
recently this is not the way ive been feeling towards my beloved f02..

The fun all started two weeks ago on my drive home from school.. all the sudden about 1km from my house there were about 10 check control messages just about all of the warning lights illuminated on the dash, the power steering stopped working along with the parking brake, traction control, abs and dynamic drive system.. kinda crucial systems if you ask me.

took it in to the dealer (BMW Toronto) and was given a 320 as a loaner (only had 150km on it!!) and returned a day later to find this interesting invoice..

Turns out the battery was the underlying issue, as well as the comfort access handle??!

Fast forward to this past friday (the 24 of jan) the car has been out of the shop for roughly a week and im greeted to this noise and a lack of power on the way to my exam..


had the car towed back into the dealer (free tow courtesy bmw), and was called on the 26 to say that the vehicle is being worked on and that the engine has to come out of the vehicle for them to diagnose.. meaning i will be stuck with 328 gt for a week!! haha

anyone know what the knocking in the engine is? it sounds high up.. maybe something in the valvetrain?

I think your car is going to get many new parts... Check out the thread on the Customer Care Program just launched in Canada

Update:
The dealer called today and told me that the one of the crankshaft bearings was "bad"..
they filed the paperwork with BMW NA to get reimbursed for the work that they are about to do.

Wow, all that work to tear down the engine only to find out it's toast.

Glad it's all covered by warranty

Yeah I recognized the sound. Crankshaft bearing going bad ruined a day for me real good a long time ago.

Congrats on the warranty.

You're lucky. Mine was repaired. It runs great though. I'm just not sure if I want to keep it longer. I was talking to an agent there last week to find me a replacement in June.

when you say yours was repaired,
do you mean they took the engine out and actually repaired all the components inside?

An upgrade would be nice, what are you looking at?

Yes, they took the engine out. Timing chains were replaced, cylinder heads sent to a machine shop, carbon deposits removed, injectors replaced, etc.

If I replace, I'll probably go for a 535 or a 740.

How many of these cars needed engine replacements? An n63 doesn't get an n63u, right? They would just pop in a revised n63.
