Mein Auto: 2004 545i
Gotcha.. mine matches the description in the service bulletin below, but I'm outside of the date range they have listed, I think anyways. Mine was a December 2003 build, but I think it was early December and this says it doesn't apply to anything that early.

However, I wonder if the high mileage on mine has worn something in the valvetronics system to the point that it's basically doing the same thing? I'm at 187K now

edit: I just checked the build date on mine, and I'm at 12/16/03. I have a hard time buying their hard cut off of the last two days for 2003 though. I work in the automotive industry and it just sounds like a supplier had to give a cut off date of when they could have and couldn't have shipped bad parts, so that is the date they went with, wrong or right. The symptoms are dead on though otherwise.

62 Engine - Rough Idle, Misfire Faults after Cold Start
E53 (X5 4.4 i/4.8is); E60, E63/64, E65/66 with N62 from 06/04 up to 02/05 production
Customer may complain of erratic engine idle speed lasting for approximately 20 seconds after a cold start.
Check Engine 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.
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.
On a customer complaint basis, and after performing diagnostic procedure described below, replace the
Valvetronic intermediate levers.
Perform basic engine diagnosis (compression, ignition, fuel pressure, etc) to rule out other potential
Allow 2. 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".
4. 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.
ote: 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:
1 of 3
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
For Valvetronic intermediate lever replacement procedure, refer to RA 11 37 012 (bank 1) and RA 11 37
014 (bank 2), found in BMW TIS.
Improved intermediate levers are currently available from 1. 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.
