WHOOOOAAAA!
 

Just got the X back today and I can't get this silly grin off my face! WOW, its like I got a brand new engine! The car not only idles buttery smooth, there is no more hesitation pulling from a stop or while rolling. I swear it seems like I gained 50hp and 50ft lbs torque! Just amazing! Wow, so this is what a 4.8is really feels like. Ever since I bought the car, I felt that my 740i sport was a faster car than the 4.8is due to weight/gearing/etc. But now, OH MAN! The 4.8is is one fast SUV! I gotta take a clip of the x-pipe now! I should have done a before and after b/c you guys would be shocked at the difference in the BARK of the engine. It just sounds totally BEASTLY!

Nice to hear!!

Yes they are beastly! Did you have the intermediate levers and x-pipe done at the same time?

x-pipe I did 3 weeks ago. It sounded good, but when I parked the car, I just revved it up to hear that nice sound, I was pleasantly surprised!

so what gave it the better performance. computer upgrades at the dealership?

:thumbup::thumbup:

JT, who did your x-pipe? Mine is still sitting in the box. Did you bring it to a local guy? I need to do mine...

I used Z Performance in Corona off the 91/15 fwy. The owner is really cool. Labor was only $120 and it was a clean job. I used them previously for my dual magnaflow install on the 740i. They're cool and let you watch.

Now for some fun! :)

I got the intermediate levers replaced. Night and day. Had a bunch of other work done too while it was there and it is like a new car again.

Thanks.. I'll go there.

SUBJECT
N62 Engine - Rough Idle, Misfire Faults after Cold Start


MODEL
E53 (X5 4.4 i/4.8is); E60, E63/64, E65/66 with N62 from 06/04 up to 02/05 production


SITUATION
Customer may complain of erratic engine idle speed lasting for approximately 20 seconds after a cold start. [COLOR=blue ! important][COLOR=blue ! important]Check [COLOR=blue ! important]Engine[/COLOR][/COLOR] Soon light may be illuminated and misfire faults for various cylinders (e.g. FC 2742, 2743, 2744, 2745, 2746, 2748, 2749, 274E) may be stored in the DME.[/COLOR]

CAUSE
Incorrect tolerances and geometry of Valvetronic intermediate levers are causing uneven cylinder filling during the transitional cold start period (60 seconds after the engine has been started) when the Valvetronic system is switching from the initial 6 mm to a minimum 0.3/0.8 mm valve lift.

CORRECTION
On a customer complaint basis, and after performing diagnostic procedure described below, replace the Valvetronic intermediate levers.

PROCEDURE

Perform basic engine diagnosis (compression, ignition, [COLOR=blue ! important][COLOR=blue ! important]fuel [COLOR=blue ! important]pressure[/COLOR][/COLOR], etc) to rule out other potential causes.[/COLOR]

Allow the engine to cool down.

Connect GT1/DIS loaded with CD 44.0, or higher, to a cold vehicle (coolant temperature below 30 deg C) and from the Function Selection select: "Service Functions", "Drive", "Engine management ME9", "Test runs" and then "Tolerance test, intermediate lever".

Start the engine and follow-up the test plan.

Observe rough running values when idle speed stabilizes. If values are in excess of +/- 2.5 accompanied with noticeable engine vibration (and sometimes Check Engine Soon flashing), then remove valve covers on both banks.

Look for the intermediate lever production date (stamped on the lever, next to the smaller roller contacting the eccentric shaft).

If the production date is in the range between "04 180" and "04 324" (e.g. day 324 of the year 2004), then the whole set of intermediate levers (16) has to be replaced. The same classification of levers must be used when ordering the intermediate levers (classification number is stamped below production date). There are 5 classifications of levers used in the N62 engine.

Note: In an individual cylinder head, all levers must have the same classification, but two different classification of intermediate levers may be used in one engine (e.g. bank 1: classification 2, bank 2: classification 3).

Important: The lower production range of the affected intermediate levers is only an approximation. It is possible that levers produced prior to "04 180" (but not earlier then "03 363") may have certain deviations in tolerances.

For Valvetronic intermediate lever replacement procedure, refer to RA 11 37 012 (bank 1) and RA 11 37 014 (bank 2), found in [COLOR=blue ! important][COLOR=blue ! important]BMW[/COLOR] TIS.[/COLOR]

IMPORTANT:

Improved intermediate levers are currently available from our Parts Department.

In the event of a reproducible customer complaint proceed with the diagnostic and repair procedure. There is no need to contact Technical Hotline.

TY NYMench.

Stupid question, but would this be covered under CPO also? The X5 that I am picking up tomorrow falls within these dates.

Was it widespread or some do and some don't?

Thanks!

They should cover it......if it wasnot already performed on the car....ez to find out...and dealer has access to to what has been done under SB or warr work.....

even if the car is our of warr...i have seen dealers remedy the problem in good faith.....

:thumbup::thumbup::thumbup::thumbup::thumbup::thum bup::thumbup:

jt///mc....

Wanna trade x5's i have a e36 m3 in the same color....and in all fairness....i think it would be better if you gave it to me....for coordination efforts!

Hey NyMench, already posted that SIB in it's original format. If you want to delete your post and just link to mine feel free.
http://www.xoutpost.com/bmw-sav-foru...ld-days-2.html

Also, technically it's not covered under CPO since it's not mentioned in the SIB, but as stated above that doesn't mean they won't cover it.

BLA BLA BLA BLA........ok :nanana:

;ph: here is your star......

its all subjective to the dealer....anywho....

Just teasing you

Are you mocking me??? Where is that "ignore" function again???

If the shoe fits!!!!!!!:stickpoke

That's it!

I almost get in trouble with my shop forman for being a sarcastic smart-ass to him... but I just tell him tact is for those not witty enough to be sarcastic.

Something tells me meister understands that!

:thumbup:

Sarcasm is a valid, diverse viewpoint. It should be integral to every workplace diversity program.

I keep telling my management that if they send everyone to "dealing with difficult people" training, I wouldn't have to go.

Definitely makes the workplace more/less tolerable! (depends on which end you are) What makes it better for me is the fact that my foreman is actually more sarcastic than me, but HATES when people are sarcastic to him! :rofl:

A smartass is better than a dumbass. Tell him that. :D

Here's an example of a dumbass employee:

Hey Boss, I Crashed Your Car | NBC Washington

Maybe I should try that trick with his car... Z4 M-coupe :D

take pics! sorry for the OT, JT :D

WOW!!! That sounds great. Is that X-pipe with stock mufflers? I'm looking into doing the X-pipe on my 4.4 soon but I can't seem to find a good clip with stock exhaust and x-pipe.

To JT///MC (since your inbox is full)

I have a question because I was looking at your post about your X-pipe. And I wanted to do it and everyone was talking about an Intermidiate Lever. Can you enlighten me on what that is if you dont mind? Thanks

-England

Sounds great - I also saw this video again where the front wheel comes up off the ground... sick.

YouTube - Bmw X5 4.8is

sorry for the silly question but what are intermediate levers

That wheel coming off the ground is the result of an extra thick sway bar... sure it loweres body roll in turns, but you see what can happen. 1/2 the rubber on the ground in hard throttle turns! I'll deal with a hair bit more roll to keep the rubbers on the ground to avoid understeer.
