FWIW this is a classic "problem" thread on this and other X5 forums.
0 - A forum member's X5 displays a warning light that can be triggered by lots of different problems. 1 - The member posts that the warning light came on and takes their X5 into the dealer. 2 - The dealer SA tells them some garbled story about what MIGHT be wrong before the problem is actually fixed. 3 - Other forum members chime in with possible causes and comments. 4 - The OP gets the vehicle back with minimal hard info on what was actually fixed and another story from the SA. A lot of this is good. The member with the problem gets support/advice from the forum. The member usually gets their X5 back fixed. We all learn at least one problem that can trigger the warning light. And everyone feels good about it. BUT...We are all left to speculate again the next time, which of many possible problems have triggered the warning light. What is missing is hard data about what actually caused the problem. BMW's warranty works against us by encouraging owner's to 'not worry their pretty little heads'. And the great irony is that our X5's are equipped with a socket that allows US to read the codes. As many of you know, the engine light on our 2009 35d came on at around 4000 miles. And I know exactly what code was set when this happened. Because I read it BEFORE I took the X5 to the dealer. Thanks to the help of forum members, I even knew the exact part that the dealer would need to fix it. And more importantly, my SA knew that I knew. The result was that the dealer managed to source a hard to get part and replaced the turbo inter-cooler temp sensor while my wife waited drinking lattes and eating pastries :) Anyone who owns an X5 can probably afford to buy a <$50 OBD II code reader. The plug is in the left hand foot well. You can learn a lot without even opening the hood. And the advice you get on this forum can shift from speculation to specification :) Funf Dreisig |
Funf: excellent post, imo! :thumbup:

Funf, Here's another contribution to the potential cause of the error. my 2010 35d w 18k miles just threw the error... took it in and my SA says its a bad EGR valve. I don't about you guys but given i've done 18k miles in 10 months the 35d has been fairly good... i've only had to go in for a) exhaust fluid refill #1 b) exhaust fluid refill #2 + replacement of the 2nd resevoir (something about it leaking) c) drivers side heated mirror cracked d) rear climate control fans making clicking noises e) high battery discharge - (they replaced the battery and a foot well module) f) 1st oil change maintenance g) re-top off of oil after the change (was 1 quart low) h) air temp sensor recall i) re-program recall j) and now.. this engine malfunction with the suspected bad egr valve 10 issues in 10 months of ownership... but i did drive it alot so i think i probably pushed it through 2 years worth of its life in 10 months... |

yeah i was going for a bit of sarcasm... i guess it didn't come across on the net... i've been relatively disappointed with bmw on the build quality of the X5... my last new bmw was a 3er and that had very minor issues... I had a used M5 and a used 745Li and both were okay... I'm really wondering if its just the quality of work that comes out of the factory in spartanburg. |

i think there's alot of merit in that... a car is a complex piece of machinery... there are alot of subcomponents and not everything is made by bmw... even if its made by bmw, maintaining quality is a pretty hard job to do.... managing suppliers especially when not in your home turf is really difficult as well. |
Got a problem on my 2010 35d that has been developing over a few months. Started slowly so didn't really notice it initially...
I had the Check engine light on and booked it in to be sorted. Dealer said it also needed the DDE and air mass sensor recall doing, so they did that. Performance gradually deteriorating and then about a week ago I got a call from the dealer saying the car had contacted them needing a service. Oil change was 4400km away but I took it in and explained my concerns over poor engine peerformance and economy especially from cold, and harsher than previous gear changes especially when coasting down. It was also holding onto gears to 3000rpm or so when previously used to change up at around 2000rpm. After the oil change etc I thought it was better, and it probably is from the engine smoothness perspective, but it still feels down in power and economy is no better (though I've not driven it very far since I got it back). Dealer notes say they did a 'ISID 6 diag system test' and 'reset adaptation'. Goes on to say the car was road tested and was ok. Service rep asked me to drive it for a week or so for adaptation to occur, and bring it back in if I'm still not happy Feels like the turbochargers aren't working or the engine is 'starved' if you see what I mean. Anybody had similar experience and managed to get it fixed? At the moment I'm likely to take it back in for further diagnosis. Peter T |
Maybe clogged fuel filter from a bad tank of gas? Just a thought......
Here's a link to a guy with a 335d that had that happen to him.... Long cranks...engine malfunction decreased power light... - bimmerfest - BMW Forums |
Many thanks for the reply. I agreed to drive the car for a week or so to see how it goes and get back to them if I'm still not happy with it.
I'm still not happy with it! Peter T |
