E90 6-cylinder VALVETRONIC Engine This is a collection of pictures of the new upcoming 6-cylinder engine for the new E90 3 Series from BMW. It is reported to make approximately 258HP @ 6600rpm and 221lb-ft torque at 2500 rpm, a notable upgrade to keep competitive with other vehicles in this class. If the torque peak is really that low in BMW's notoriously flat powerband, it will be really fun to drive. It utilizes a new magnesium-aluminum alloy crankcase shaving off about 22 pounds. It makes 12% more power and consumes 12% less fuel. It will also be seen in the new 630Ci, X3, X5, Z4, and more. There are numerous other upgrades to this moto thanks ben

My bmw x1 2010 model indicated a ccid29 error. after that the car performed better than ever i then drove for 160 miles and specialists ran a scan and said the valvetronics were sticky.


Hey Jank. Did you have the valvetronic actuator limits taught in after reinstalling it? It may be in a fixed position if it was not adapted.

What is the 2851 error code on E90 BMW 320i 2009 model


I believe it is referencing your Valvetronic adjuster motor, the one that advances (changes) the timing of the valvetrain under varying RPM. Here is an excerpt from a do it yourself fix if you are mechanically inclined:
Recently I had a E90 320i come into my shop with the mil light on and running on half power. A scan of the vehicle indicated valvetronic servor motor internal failure. On testing the valvetronic servor motor I found it to be working.

The problem was it was not advancing the valve timing thus the half power of the engine. If you ever have this problem here is a fix that works. Remove the servor motor and. With a screwdriver push the eccentric shaft gear as far back anti clockwise as it can go. Insert the servor motor and connect its 2 pin plug. Them switch the ignition onto position 2 and withing a space of 15 seconds depress the accelarator pedel down to full throttle 10 times and you will hear the servor motor program itself back to factory spec. Re-fit the valve cover and problem solved. I hope you will find this post useful.
Good luck...

SERVICE STEERING SYS
Refer to Variable Effort Steering System Description and Operation in Variable Effort Steering

Your best bet , take it to the dealer .
Variable Effort Steering System Description and Operation
The Variable Effort Steering (VES) System varies the amount of effort to steer the vehicle as wheel speed changes or lateral acceleration occurs. The Electronic Brake Control Module (EBCM) controls an actuator located in the steering rack and pinion. The actuator consists of an electromagnetic coil and a pintle valve which moves in and out of the rack and pinion's input fluid orifice, regulating power steering fluid flow. The EBCM commands current from 0-1 amp to the VES actuator which varies the amount of effort to steer the vehicle. At low speeds, 1 amp of current is commanded to the VES actuator and the pintle valve is fully retracted which provides maximum fluid flow and maximum steering assist for easy turning and parking maneuvers. At high speeds, no current is commanded and the pintle valve moves closer to the orifice, decreasing fluid flow, providing firmer steering (road feel) and directional stability. The VES system uses the steering wheel position sensor input to calculate lateral acceleration during abrupt driving maneuvers. The system also uses the Antilock Brake System (ABS) wheel speed sensor inputs to determine vehicle speed. The EBCM is constantly monitoring these inputs to achieve the desired current to the VES actuator. The EBCM has the ability to detect malfunctions in the VES actuator or the circuits to the actuator. Any malfunctions detected will cause the VES outputs to be disabled and the EBCM will command the Driver Information Center (DIC) to display the SERVICE STEERING SYSTEM warning message via a class 2 serial data circuit.

BMW E90 LCI, after a long distance trip the engine started making a noise. Had the head fixed, then the car was not picking up RPMs, had the computer box changed to the original, car worked fine


noise could be timing chain tattle due to tensioner failure, fault now sounds like valve timing wrong after changing vanos, there is special tools to set them up, also check the valvetronic servo motor. Scanning for fault codes will also be very useful

I have a BMW 318i saloon. I got a P0015 P trouble code. The engine stoped during driving. Could you please let me know where is wrong and how to sort it? Many thanks Ben


Hi, the indication is either your timing belt has skipped a tooth or the valve timing actuator has malfunctioned. The engine valve train will have to be taken apart and diagnosed by a mechanic that is familiar with variable valve timing engines. Please let me know if you have more questions and thanks for using FixYa.

After diagnosis my v8 740i bmw indicated the "variable valve gear guide sensor for bank 2 and variable valve gear learning stops necessary" currently it's difficult accelerating the engine. would...


You have a v8 with a "variable valve gear guide sensor" on each bank. The trouble code is telling you that bank#2 sensor is faulty, or its signal is not getting to the engine computer.

Consequently, when bank#1 adjusts the timing (under hard acceleration or higher revs), bank #2 is not getting adjusted.

If the variable valve timing is not being activated (low load, load revs) the engine will run more or less normally.

Get the car to the dealer. You risk MAJOR ENGINE DAMAGE if you keep driving it.

Diagnoses : 2002 745i bmw ( hot-film air-mass flow senser )


Hot-film air mass sensor when diagnose say is damaged, replace it!!! Trouble when car will take up to 5.sec. is associated with this! Bank 1, the accumulated value of lambdasond the left side of the engine cylinders. While the problem is in the ignition at the 4th cylinder, Bank-1 data were then evaluated as poor. Allow change fourth ignition coil and the CAN mistake Dont look it! is an accidental fault! eventually allow for BMW servicing erase all the mistakes and make a new adaptation of the engine throttle body, and adaptation of the engine in to "0" setting
