BMW ENGINE LAG PROBLEM

BMW N62 GAS PEDAL ENGINE LAG!

On BMW N62, N63 and other engines especially e65, e66, e60, e63, e64 series most likely you might experience some gas pedal lag delay or uneven power delivery at lows. It feels like you press on it and engine barely revs from lows or it revs, but you have to press it harder to feel it. Assuming engine and tranny do not have any problems and all other components run as they should, I mean no vacuum leaks, all sensors read correct values etc, but still it feels like gas pedal is slow at lows, usually in the city driving. Funny part BMW will tell you its normal lag because of drive by wire nowadays standard, though there was no delay on m62tu engines with similar drive by wire gas pedal back in 1999. Lots of people buy some magic gas pedal boosters 200-300$, but they should understand, that this booster simply sends 2x signal to DME (engine brain),so it basically feels like you press 2x harder. This method (if you call it a method) is not a good one for a few reasons:




-it will make your car less smoother or some say it fells jerky

-not safe, you can easily rear end someone in the city

-premature transmission wear and tear

-overall more stressful for the engine and tranny

-higher gas consumption

-overpriced 200$+

So we have been looking for a solution for a while and looks like we found it!!!

and its all original BMW OEM. You simply need to replace your gas pedal assembly with the newest one they sell at the dealers or online, but make sure they sell you the newer design, because newer pedal assembly is way better and has newer chip built in, also it has newer pedal design, so it wont get sticky if dirt or water gets there. You will be really surprised, that the lag will be gone and bmw will perform like it should without any lag from lows and overall will make it fell much smoother. Look at these pics:

newer part number is: 35426859999

you will find this pedal installed on the newest BMW F series

you can get it form the dealer or online, just make sure they sell you newer design only, because lots of sellers still have old pedals in stock.

newer gas pedal design:

newer_gas_pedal

newer_gas_pedal_sideview

older gas pedal design:

old_gas_pedal

gas_pedal_old




   It is very easy to remove it, just remove plastic cap,  unscrew the metal screw 2, and then disconnect a connector. Install a new one and done! you can reset engine adaptations, but not very necessarily, it will work as is.

Basically BMW updated gas pedal design for that reason, but of course they didn’t recall it, so they know this problem really well, otherwise why they completely redesigned it??

This modification will work on any BMW with similar part numbers.

BMW E65, E66, E60, E63, E90, E92, E93, E64, E87, E53, E70 AUX PORT MOD MODIFICATION

Yes, it is very annoying, that BMW decided not to install aux port by default in our vehicles before 2007. In this post let’s find out what you need to get for AUX port in your bimmer.

E65 BMW 750I, 750LI, 760LI, 745I, 745LI, 730I, 730D ETC.

If your car is pre 2007, and you don’t have aux port in your idrive and neither you have aux port in your glove box- you are not in very good shape. To say the least its the hardest bmw body type if you decided you need aux port! Why?  Because ask unit cd player and pretty much all multimedia modules in this car are digital, and there is no analogue signals anymore, and aux port signal is analogue, so common sense tells you need to convert it to digital bmw e65 signal in order to get sound from your sound system, doesn’t sound easy at all to say the least.

So here are the options:

  1. BMW E65 FACTORY OEM AUX PORT INSTALLATION.  DO NOT EVEN THINK OF BUYING BMW OEM AUX CORD JUST BECAUSE SOMEONE SAID ITS SO SIMPLE: BUY THE CORD 5-75$ CONNECT OT THE BACK OF YOUR ASK UNIT AND DONE??? REALLY?  YES, CORD WILL FIT IN THERE AND THAT’S IT HERE- YOU WILL NOT GET ANYTHING WORKING APART FROM THAT GOOD SIDE YOU HAVE USELESS AUX PORT IN YOUR CAR. WELL, HERE IS WHAT YOU NEED:
    1. IF YOUR CAR IS PREFACE LIFTED 2002-2005  BMW 745I, 745LI, 760LI, 730I, 730D, THEN YOU NEED NEWER TYPE MMI SCREEN FROM 2006-2008 MODELS PLUS NEWER 2007-2008 ASK UNIT CD PLAYER. AND AFTER THAT YOU HAVE TO CODE BOTH TO YOUR CAR USING NCS EXPERT BMW PROGRAM TO ENABLE AUX INPUT IN MMI SCREEN (IF SCREEN CAME FROM 2006 CAR) AND CODE ASK UNIT TO WORK WITH YOUR TUNER AND OTHER MODULES. WHY? BECAUSE EVERY CAR  HAS DIFFERENT OPTIONS AND FOR EXAMPLE RADIO TUNER WILL NOT WORK WITH NEWER ASK UNIT IF NOT REPROGRAMMED OR RECODED, ALSO SOME CARS WERE EQUIPPED WITH L7 TOP HIFI SYSTEM VS STANDARD HIFI SYSTEM, THAT’S WHY THOSE MODULES HAVE TO BE CODED. AND ONLY AFTER ALL THESE PROCEDURES YOU CAN BUY AUX BMW CORD AND IT WILL WORK! ALSO YOU WILL NEED FACELIFTED WOODEN TRIM, BC YOUR ORIGINAL WILL NOT FIT ANYMORE.
    2. IF YOUR CAR IS FACELIFTED 2006 BMW 750I, 750LI, 760LI, 740D, YOU ARE IN BETTER POSITION. YOU WILL ONLY NEED NEWER ASK UNIT 2007+, BC EVEN THOUGH THEY LOOK THE SAME, HARDWARE INSIDE IS SLIGHTLY DIFFERENT AND ONLY LATER 2006 (WEEK 30 AND UP)+ MODELS WILL WORK WITH AUX UNIT AND CODING MMI SCREEN TO ACCEPT AUX INPUT, THEN YOU WILL GET AUX IN THE MENU AND EASY WAY TO CHECK IF ASK UNIT SUPPORTS AUX IS TO SEE IF IT RETURNS AUX LEVEL AFTER YOU CHOSE AUX IN THE MENU. OLDER ASK UNITS WILL NOT RETURN THAT LEVEL SUB MENU.

2. NON OEM AUX PORT CAN ONLY BE INSTALLED VIA RADIO TUNER MODULE, YOU WILL GET CLEAR SOUND, AND IT WILL OVERRIDE ANY RADIO STATION. VERY SIMPLE, YOU PLUG YOUR PHONE AND YOU WILL GET CD QUALITY SOUND. IT WILL ONLY WORK IF YOU DON’T HAVE HD RADIO MODULE. WILL WORK WITH ANY E65 2002-2008.  THIS IS TOTALLY DIFFERENT COMPARED TO LOW QUALITY RADIO TRANSMITTERS MODS. IT HAS NOTHING TO DO WITH FM/AM, IT WILL OVERRIDE SOUND SOURCE. WORKS VERY GOOD WITH APPLE DEVICES. IF YOU NEED HELP WITH AUXILIARY PORT INSTALLATION YOU CAN EMAIL FOR DETAILS.

ALL OTHER SERIES ARE MUCH EASIER. E60, E90, E63, E64, E92, E93, E87, E53, E70 WILL ONLY NEED AUX PORT ENABLED VIA NCS CODING AND BUYING A CABLE.
