August 1, 2017 Followup from the Pelican Staff: Possible. Each intake valve 2 per cylinder is opened not directly by the corresponding camshaft but by an additional mechanism which varies the valve lift. You can clean or replace the solenoids quite easily if needed. That is about all that caused a misfire. Tests that I have preformed, leak down cooling system pressure compression fuel pressure all related power connections checked.
I wanted to know why the entire valve cover assembly would need to be replaced? Could dropping one cause it to fail? Any thoughts or ideas, including whether it's safe to drive the car or it should be towed? Granted, this is an oversimplification, because we have to recall that the cylinders are moving fast, so the valves actually open and close before or after those strokes have begun and ended. Changed vanos intake and exshaust,new plugs,new coils. Not throwing any codes at all. April 30, 2018 Followup from the Pelican Staff: Sounds like an engine misfire. After having a completed the cylinder engine re-do with sparks and coils, computer fully regeristing -I am not a fan any longer! Can you confirm injector pulse and flow? Reinstall and clear fault codes.
I would appreciate any advice you may have regarding the issue. Is the check engine light on or flashing when the problem is present? And car became very sluggish , so I took it in and the workshop told me that the vanos gears are faulty. Use camshaft and crankshaft alignment tools to confirm engine timing is out of sync. Checked solenoid and cam sensor all good. The engine runs fine but it has a 2A83 vanos intake error. Check the wire harness for damage, chafing, exposed or broken wires.
Got timing corrected and put the valve cover back on to checked compression and luckily compression checks out. I would retest those items. When repairing this system, be sure to set up valve timing and the timing chains very carefully. Those faults are always timing related. All brand new spark plugs and coils.
December 15, 2016 Followup from the Pelican Staff: What was the problem before replacing the solenoids? So, he cancelled the light and hasnt started since! March 28, 2017 Followup from the Pelican Staff: See other question for guidance. All pictures and manufacturer information is for identification purposes only. My question is what cr is this solenoid supposed to put out? Please read the application listings below to ensure you are purchasing the correct part. They can figure out what part or repair kit you need. I have a couple thousand miles left on the warranty. The fact that he checked for vacuum leaks and none were found, but your car still has a lean issue at idle tells me that the valve in the cover is indeed bad.
Sure enough a week later the check engine ligh comes on. Horsepower and torque loss noticeable during acceleration and a drop in fuel economy. The vehicle in question is a 99 323i. September 6, 2018 Followup from the Pelican Staff: It didn't slip, chains don't do that without catastrophic failure. Gear D mode, foot pressure on break pedal. As of now it still goes into engine malfunction mode and I'm running out of ideas of what to fix. The vehicle has just over a 100k, and even though it was a one owner, there were no records with it, so I have no idea of what, if any maintenance has been done.
Insert the solenoid valve back into the cylinder head and torque the bolt to 9Nm. Also can the brain box and oil sensor cause this issue? Tensioner seems fine but I may change that just to be sure. . July 13, 2017 Followup from the Pelican Staff: Could be an issue with the fuel pump. What direction should I look into? The number 3 seems a little lowder than is used to be. As of right now it reads: vanks position inlet 76.
I even bought a new cap from them. Just before the error occurs the car has slower pickup between 1500 and 2200 rpms. Bad solenoids will result in poor performance, rough idling, limp mode, loss of power, inability to accelerate…. Thx, Nick January 18, 2017 Followup from the Pelican Staff: Crankcase pressure is checked t the oil cap. Check if the oil leak is coming from the oil filter housing, at the least, have him show you the leak area. Engine power is not controlled by the throttle valve but by intake valve lift. If you need a quote on parts let us know exactly which ones you need.
But, when returning to level ground, it jerks, especially if cresting the dip or hill then, going downward. Have a great day ahead. January 6, 2019 Followup from the Pelican Staff: Could be an issue with the fuel pump. Now, at regular idle is hiccups and misses and is very noticeable and sometimes will raise its idle to 700 but misfire is still noticeable, seems to slightly miss under acceleration around 1K-2K rpms. Does the bolt do the rest? If incorrect, replace the valve. I would think that such system would need oil pressure to function, and that the system would return to, if I may, the default, or off position if you will, when the engine is not running.
