The actual angle also varied as in the previous test but on average was nearly equal to the desired angle. BTW what can you tell me about the chain stretch check procedure? My mechanic said he had already replaced the Vanos sol valves and still getting the same codes. N20 and N26 Engine: Various VANOS System Faults Stored in DME Yes, tricky to work out.

If you are interested here is the rest of the story. The M62 V-8 (1995-2005) was notorious for failed timing chain guides. New Member. So the two snap tabs should not bear weight/force, correct? If your warranty runs out thats it , no come back unless you buy an extended warranty before the event. Do you think is this something related to eccentric shaft sensor? The last oil change was two years ago but only 2200 miles were driven. This time the desired angle was not a constant as in the previous tests. Basically, this systems allows the ECM to monitor the mechanical timing between the camshaft and the crankshaft. Check fuel pressures for the high and low-pressure pumps. Changed the oil filter and OIL. And most likely a cold start issue as well. Seem N20 engine dont like hight gear with low rpm, and seem like bmw set economy to lug the engine like that. https://www.bmwtis.net/tiscode/cgi-bin/bulletin.aspx?sie_path=/tsb/bulletins/htm_store/158 1/6/2014 There are locking pins integrated inside the units. Yes it should,,,,but sometimes some random faults might still be their, The service engine light has not cleared. There was junk trapped I've been told in the oil passages blocking lubrication of the crank etc Hi, I have N20 with rough idle. Hi I have a 2013 bmw x1 with a N20 engine. Is that possible?

To determine if any applicable Federal, State or BMW Emissions Warranty coverage applies prior Is there a or way trick to clear the code without seeing a mechanic or using a code reader?ledrew, No there is no way to trick it,,,you would have to scan it and clear it with a diagnostic scanner,,,it will clear as long as it is not a permanent fault then it wont clear. But I realized that the part of the chain Im touching is between the two camshafts, so the slack could also depend on where each camshaft stops rotating on the lobes in addition to what the tensioner is or isnt doing to the slack side of the chain before the first camshaft. Cant see any signs of metal filings in the oil either. Anyways I spend 20 hours replacing the chain. Knocking sound also weakens when the engine gets to operating.

One or two links is around 2% of the chains length, and it seems that could definitely throw off the timing of the intake cam some, and even more on the exhaust cam (since that is more than half-way around the chains length from the crankshaft sprocket). Not sure if he meant evap leak. The double whammy is that not only did they not put enough spring force into it at first, they also didnt have enough travel to take up additional slack. Andreas first and foremost thank you for sharing your knowledge. I have checked timing multiple times, I found this article online and this is what Im thinking right now!! The car ran for a mile or so then seized. So I strongly suspect a poor tensioner design is the root cause, and other weak links hasten the system to failure. I see only this at Home Depot: When I'm dead, just throw me in the trash. Posts. It revs fine but with the turbo disabled a drive around the block is at a pedestrian pace. The oil and filter were changed along with the timing chain. Thanks, The charge pressure fault is probably due to the the vanos fault,,,,it looks like you replaced all the general stuff already and you are sure the timing is correct,,,,,you said the engine had low water damage what does that mean,,,is it possible the exhaust camshaft is binding,,,,you might want to check the exhaust camshaft journal caps.

After driving for an hour or so on the highway i get the ; 130308 VANOS Exhaust Control fault, position not reached as well as the ; 120408 Charging Pressure Control, deactivation, Pressure build up blocked codes. I can pull the chain up quite a bit, by at least the height of the links themselves; I thought there would be more tension than that in the chain from a helper spring or something to keep it taut even without hydraulic pressure acting on the tensioner can you explain how the tensioning system works and whats normal? The ECM is majorly affected with this kind of problem, which is why a technician should take a look at your vehicle if this trouble code or related ones appear. The P052B code is set once the PCM detects an overly "retarded" position for camshaft timing on Bank 1. 61 00 720 Refer to KSD2 Programming / encoding control unit(s) Even though work time labor operation code 61 00 006 ends in 006, it is not considered a Main It is a total mystery (to me) as to why it works now.

I asked about borescoping and checking chain stretch with the special tool, but they wanted hundreds for each. I dont think genuine camshaft sensor will solve your problem,,,I think the timing chain might have jumped causing the camshaft to be retarded. I replaced botttboth sensors but the car still wont start. Is my engine seized because of this scenario. Typically, this happens due to cold startup. Another system the ECM is required to monitor and adjust accordingly is, the variable valve timing (VVT) system. Lieutenant . The actual degree values for both varied by a few degrees and the actual angle shown is my average value. Also is it possible the timing had jump and its not building oil pressure to start the car. Cleaned spark plugs and as the mileage was 65000 so I changed the timing chain with a TOOL also. I dont have that issue with city driving. I have seen faulty sensors cause engine stalling and poor engine drivability. There not much to tell you about chain stretch,,,,I think a lot has to do with the timing chain rail getting worn out or start to come apart and then the chain starts to loose tension because of the rails coming apart,,,then when we have a loose chain then we have timing issue. Click on the 2D61 VANOS, exhaust, control fault, position not reached Seems to be driving and starting fine but not sure if I'm doing damage by not addressing it. Do you know if the new Vanos assemblies comes with the upgraded bolts or do I still need to change out the 4 Vanos Gear bolts on a new assembly? Error Code P052B takes place when the PCM has monitored an "overly" - retarded VVT position for camshaft timing on bank 1. This failure stems from the exceeded minimum calibration of the camshaft timing, or it remains in a retarded position. The engine was low water damaged. Yesterday I did get all the fault codes cleared. Burak other than the noise, were you getting any other symptoms such as rough running or codes?
