One of the biggest problem with my X6

[lonely_dxb83]

hey everyone,,

I am really disappointed with my X6, its V8 2008 production.

The car was performing well at the beginging, then later on it started to became more havier in driving,,,

This is what happend, I was driving on the highway, speeding normally from 0 up to 200km, once it reach 200km, the rpm remain on the red line 7-8 and after that, directly I got the check enging light, reduce power msg, however I turn the car off, then on, the msg gone,,,

I tried for many times, and sometimes when I reach 170km, the rpm remain on red line and u feel the gear not changing any more and directly the check engine light msg,,

I took my car to the dealer, they said its the high pressure fuel pump problem, they change it, reprogrammed the car, once I took the car again from the dealer, the driving were perfect and the car wasnt heavy any more,,, I had doubt that maybe the problem still arrised, I tested my car again on highway, and again the nightmare appeared, the check engine light msg was there,,, I tried it many times, and again and again the same msg,, I took the car to the dealer,, and they told me they will test it,,
they change the turbo relay,, and I went with the technician for the road test, and i drove my car again and the msg appeared again, he told me maybe there is some electric problem or some cooler with turbo problem,,,

I will wait today for there call,, and i Dont know what they will tell me,, I really started to hate this car,, its too bad when u pay alot of $$ and u got problems which made u hate ur car,,,

one more thing,, before appearing the check engine msg, when I was driving my car up to 200km, the car perfoming more and u feel u can have more accelaration and speed and u feel the turbo pushing the car more and feeling its perfomance on the road, and now NO, up to 200km and rpm goes to red line and check engine appear,,,

please if anyone have any opinion towards that,, let me know as soon as possible,, DO u think if the problem arrised again, I have the right to replace the car with the new one?

Waiting,,,,,,,,,,

Sorry to hear!

Well make sure they check the battery is the correct one, I know doesn't sound right but if you check this forum you will see it was at the cause of a lot of weird problems.

If you look at this thread (http://www.xbimmers.com/forums/showt...69#post4821169) you will see someone else is having similar issue, you might want to PM them to see how theirs gets fixed.

As far as replacing the car I would ask your dealer to get BMW involved. When I had my "check engine light problem" the first thing the dealer did was replace the DMTL pump as that's what the code was showing, didn't fix it (they exchanged lot of info with BMW). My final fix was battery replacement and reprogramming the car , not sure which fixed it.

I understand your frustration in paying a lot of money for a car and having it break not when it's old but when it's brand new.

What kind of rattle?

I hear A/C chatter when the vent opens/closes with temp. I can duplicate moving the thermostat/temp setting from high to low. Sometimes it hunts for optimum vent setting making a chatter noise for a few seconds.

Let them try to fix it one more time and then ask BMW for a new vehicle. Sorry for all your problems. I can understand your frustration and have already been there and am on my second X6 now but this one seems ok so far.

Just out of curiosity, what's your ambient temperature and humidity level when you push the car hard (or at least you are trying to)?

Maybe it's overheating the engine/turbos?

You seem to live in a somewhat warmer climate than we do

Just a hunch, idrive has a speed limit preset. check whether it's turned on.
i've never set it so i don't know whether its an audio alarm or combined w/ engine control.
what's the engine temperature when this happens? if it's overheating turbos it could happen @lower speeds too right?
BMW offer any reason/cause for this & solution yet?

The iDrive speed limit function only gives you an audible warning tone when you go over the set speed limit and it will also show you a message in the iDrive display and in the instrument cluster that you are now 'speeding'.

It does NOT influence the engine in any way.
