Help on hot start shaking!!!

Hi All:
VANOS solenoid already replaced.
My 08/328xi now starts to shake sometime when hot start, cold start is fine and driving is fine. Only when hot start it shakes, restart solves it immediately.
The only error stored is 2A82 and I have attached some numbers here.
You can see the camshaft inlet is always 114.75 degree when it's supposed to be set to around 65 degree. The temperature is always around 90 when shake happens. Are these number normal and why it's always 114.75 degree ?

Since it only happens when engine hot starts, is it possible that battery or starter is weak when temperature becomes high or vanos actuator tends to fail when hot starts? After car is started they will be fine even with high temperature?

I really appreciate your guy help.
Thanks.

This would be yet another recent person to have this issue on N52 motor if so.

I was considering several possibilities:
1. VANOS actuator: high chance, difficult to fix. but why drivingis fine.
2. camshaft bearing ledge: not sure, same reason as above.
3. camshaft sensor: should be fine.
4. battery: really have idea...
5. coil and spark plug: I don't see any error stored, is it possible this cause any problem without setting error code?
6. eccentric camshaft sensor: low chance.
7. no vacuum leak as I tested.
All in all, I think sensor should all be fine, the problem lies on low engine oil pressure or fuel/oil ratio when initial start.

found this SB

SI B 11 05 05
Engine
December 2006
Technical Service

This Service Information bulletin supersedes S.I. B11 05 05 dated November 2006.

SUBJECT
N52 Engine Runs Poorly with Camshaft Sensor and VANOS Faults
MODEL
E90 (3 Series), E60 (5 Series) with N52 engine produced from 3/2005 through 6/2005
E90, E91 and E92 (3 Series) with N52KP and N54 engines from 7/2006 production
E85 and E84 (Z4) with N52 from 1/2006 production
E83 (X3) with N52 from 9/2006 production

SITUATION
Vehicles equipped with the N52, N52KP and N54 engines may be difficult to start, run rough and have the "Service Engine Soon" light illuminated.
Any of the following camshaft sensor or VANOS faults, as well as various misfire faults, may be stored in DME fault memory.

2A9A Cam sensor, inlet signal signal invalid for synchronization

2A98 Crankshaft-inlet camshaft, correlation- Value outside reference range

2A82 VANOS intake- stiff, jammed mechanically

2A9B Cam sensor, exhaust signal signal invalid for
synchronization

2A99 Crankshaft- exhaust camshaft, correlation- Value outside reference range

2A87 VANOS exhaust- stiff, jammed mechanically

CAUSE
VANOS solenoid valve is jammed or sticking.

CORRECTION
On a customer complaint basis only, perform the diagnosis and repair procedure as described below.

PROCEDURE
E90 (3 Series), E60 (5 Series) with N52 only:
Remove the VANOS solenoid, intake or exhaust depending on the fault codes stored, and using shop air, gently blow out any visible particles and reinstall.
It is no longer necessary to replace the VANOS solenoid on the N52 Engine.
Reprogram the vehicle using CIP17.01 (Target data Status E89x-05-06-510), or higher for the E90 and Target data Status E060-05-06-500, or higher for the E60.

The modified MSV70 DME data contains additional VANOS solenoid activation logic to flush out any foreign particles.

E90, E91 and E92 (3 Series) with N52KP and N54 engine, E83, E85, E86 with N52 engine only:
Swap the faulted VANOS solenoid with the opposing solenoid to verify if the fault follows to opposing location. If the fault follows replace the VANOS solenoid.

PARTS INFORMATION
Part Number Description Quantity

11 36 7 516 293 VANOS Solenoid 1
WARRANTY INFORMATION
Covered under the terms of the BMW New Vehicle Limited Warranty.
Defect Code Refer to KSD

May be worth a try to clean the vanos solenoid
