MAF Replaced - Before/After
 

Just changed my MAF and what a difference. I still am getting some jerkiness but its about 70% less than before. The car also pulls alot stronger and I am so glad that it wasnt the transmission. I never had the tranny slip so my presumption was wrong the whole time. I am thinking about cleaning the throttle body but anymore suggestions to do next is appreciated.

Is there a write up i can follow for me to do by any chance?

get some MAF cleaner from Kragens and go that route as well...

Anybody have DIY cleaning for the MAF?

pull it out, use CRC MAF cleaner. let it dry. put back in

Can you describe the jerkiness you were having in more detail?

Here is a link of where this has been discussed before, with a link on a how too guide. It may be an M5, but similar to our X5 ;)

Okay guys, I was out testing the X5 out after installing the new VW MAF and seemed to be fine until I came to a full stop. Funny how one problem is almost resolved and new one appears. So, now that the jerkiness/hesitation has cut down tremendously I noticed that I am getting a kick in the rear when the vehicle gears down to first when coming to a complete stop. The L/100kms needle also fluctuates. I didnt have this before the install of the MAF and reading some old posts suggest cleaning the throttle body and fuel injectors. The messed up thing is that I dont get any hesitation or kicks at all when in Manual mode or even in sport mode, not a single glitch. The X5 seems to be better on gas in Sport mode, that cant be right. I am so puzzled by this vehicle its driving me nuts. I initially thought it was the tranny and now the puzzle seems to have gotten larger. The good part of all this is that it seems not to be the tranny. Anybody have any suggestions on what the problem it could be?

The jerkiness or hesitation is when I lightly accelerate to and around 40km/h, the car just heavily vibrates back and forth, feels like a bad ass earthquake maybe a 6 or 7 on a Richter scale. After replacing the MAF, the earthquake is down to 2 or maybe 3 on the Richter scale. I hope that describes it. I will try to make a video if you need more of a description. I just dont understand why I am getting the gear down kick into first when coming to a stop.:rolleyes:

CRC MAF cleaner is a waste of money and putting off the inevitable...it's like cleaning spark plugs instead of replacing them. The MAF cleans itself by basically overheating itself when needed, essentially burning off any deposits. After a while, it gets too much resistance and simply needs to be replaced.
