Thank you ! Very helpful.
great it helped. thank you for subscribing.
Thank you man ! Very usefull video :)
Thank you for your comment. Have a good day!
I got P0011 after cleaning the two magnet ventiles on "A" Camshaft Timing or something, any idea? Maybe i dient turned them right direction or som? I really need assitance with this id be so thankful
hi, you could check the wiring plug connections and make sure they have good contacts. you can try to clear the code and to find out if they are coming back again. if they do come back, you could swap the two sensors to find out if you will have a different fault code, and then start from there? Good luck!
What are the two sensors with the metal brackets next to the intake sensor mine are leaking oil and need replacing/cleaning?
hi, they are vanos solenoids. the o-rings can be replaced if leaking oil.
1. how to remove, watch this:

Annoying change mine stil getting the result an faulty still bot starting
Hi, my exhaust sensor is leaking oil and is probably damaged by it. It threw out a fault code. Should i replace both sensors? The part is pretty cheap. Thank you for the vid.
leaking oil is caused by the sealing rings and it is different from a faulty sensor. if you do have both a faulty sensor and a leaking seal, you could solve both by a new sensor with a new O-ring. it is recommended to use the OE sensors, even second hand ones. have a good day!
@@RepairDIY i meant if i should change bothe exhaust sensor and intake sensor. Thank you!
@@TheBestWanted112 Sensor shapes: older sensors have the thinner ends and newer shape has thicker uniform sensing end. Replace both if your aims are to fix oil leaking and faulty sensors, or if you are replacing old-shaped sensors with newer bolder shaped sensors. cheers!
Once again great video . Today my car gave P0012 code . Would it relate to this sensor ?
HI, it could be the sensor but the hydraulic system is very important for this engine to operate normally. Check you engine oil level and freshness before trying to replace the sensor?. The low engine oil pressure was the main problem for my BMW. Good Luck!
@@RepairDIY I got the same code on bmw 1 series I have one bad O ring black that can cause the code? Om vanos? My car sound little bad and yellow egine lamp. Or camshaft?
@@Data4664 hi, if the oring is no longer good, you could replace it first and clear the code. Vacuum leaks and low oil pressure may also trigger the sensor fault codes. It should be good to start from basic checks before trying to replace the sensors. Good luck!
Hi is the two sensor both the same. And can you pls make a video on how to test if the camshaft sensor is working or not pls. Thanks
Hi, the two sensors are the same. as far as i know, there is no easy way to test the sensor. with some expensive tools, you may be able to watch the sensor signal waves but that should be beyond our reach as DIYers. Good luck!
czcams.com/video/4AnSzKzyzh8/video.htmlsi=Wb3gZETNP1cKth2x around 7 minutes he explains how to test it
My car impossible start every morning..so which one should i change..intake or exhaust..tq🙏
Read the fault code first before thinking about replacing any sensors? If it is difficult to start, it could be the crankshaft sensor? So read ODB codes first then considering any replacement. good luck!
Are the parts the same part number ? Thanks
Yes, they are the same for both intake and exhaust sides. cheers
Hello my n42 2002 318 has a misfire 1347 code and cut off fuel in cylinder 3, but some times when I search the code shows camshaft sensor, the bad sensor can make a cut off fuel in cylinder? Thanks
I think a faulty camshaft sensor should not cause cutting off fuel? But a faulty crankshaft sensor can stop the engine. You could check the plug and coil for cylinder 3? good luck!
Thanks for the video . What are the symptoms for faulty camshaft sensor on your car. I have the same engine. Please reply asap
hi, main problems are the rough idle and less engine power. read the faulty codes before considering replacing it. have a good day!
@@RepairDIY which error code or which message should i expect? Lean trims or similar maybe?
@@estewarrior1 hi, you should have fault codes point to the camshaft sensors, intake or exhaust. I did get codes before i replaced them. please remember to always start from basics, such as spark plugs, fuel pressure , oil and filter, air filter or oil pressure, before replacing these sensors. I replaced these several times and finally found it was oil pressure problem. Good luck!
@@RepairDIY Hi! What was the cause for the oil pressure problem?
@@robertalexandrescu9975 The oil pickup tube in the sump was loose.
nice to know that there are two...
Hi, I have changed my camshaft sensors several times as I had the camshaft sensor fault codes and engine noises. Please note that loose timing chain, faulty timing chain tensioner or low oil pressure can cause the camshaft sensor fault codes. Cheers.
RepairDIY hi if the car have a lose timing chain you say the fault will still come out or will keep coming out? Do you have a video to change the timing chain? Thanks for your quick reply
Where can find these sensor. I order the wrongs ones. Thank you
Hi, if you are in UK, you can try gsf or ecp(eurocarparts) websites, you can enter your car's registration plate number, then the website normally can find the right parts for you. if you live other countries, you should be able to find similar websites. good luck!
Hi can you reuse the screws bmw saying they are only 3$ but they have no screws in australia and 1 month to import from germany :/
Hi, I always reuse them. these bolts/screws are tightened to 7 Nm. Be careful of not being over tight. in my haynes manual they are not marked to "only use the new bolts". I agree that new bolts/screws/nuts are always better if available. Good luck.
@@RepairDIY Ok thanks man ill try reuse them carefully :D
Hi, sometimes i only torque it to 5 Nm and it 's never got loose by itself. cheers.
ty. i got the sensor part: 12147518628 for 13$ on ebay
but its different shape to the original which is a bit shorter and has thinner column for most of the length
the new sensor has one large column shape for whole length like the one in your video but it seems it wont fit
hi, the new shape is different from the original one back in early 2000s. if it is the correct part, you should be able to put it in. check the diameter of the column is indeed smaller than the hole? lubricate the oring and the sensor with engine oil. you could also try to put the oring first into the hole to the rest position, then insert the oiled sensor. some new orings may be difficult to put in but they should seal better than the old ones. good luck!
Hello
They are both the same ?
Yes, they are the same. Cheers
so how do I know which one is faulty? I assume they're both the same.
Yes, you are right, the two are the same. The best way to tell which one is faulty is to have an OBD fault code reader, which displays the fault code and may also display the meaning of the code. I f the reader can only display the code, you can easily to search the internet to find the meaning of the code. You could replace only one or both. It happened to me the first time the code indicated to replace the intake-side cam sensor. After I replaced, then a new code indicated to replace the exhaust-side cam sensor. good luck!
@@RepairDIY What code reader do you recommend I get for my E46 316ti N42 and of course that would work with newer model bmws?
@@kay19833 Hi, I only have several cheap readers, bought many years ago. One is RAC code reader (UK, simple, common codes only); Another one (D900) can read some live stream data and display in graphs. I also have one with touch screen, which can read BMW codes, such as ABS sensor faults (this reader has a lot of problems but it does work to read some BMW codes while the other two can't). It will be good to buy one with live stream data features, or one designed specifically for BMWs, Good luck!
@@RepairDIY Do you know the name of that one that reads bmw codes?
@@kay19833 Hi, it was a stand-alone device without needing a computer to work. It was a touch screen version. I paid £40 for it. I just searched ebay, and didn't find it. but it is very similar to this without touch screen.
www.ebay.co.uk/itm/BMW-Diagnostic-Tool-Latest-Interface-Code-Reader-Scanner-Engine-Airbag-ABS-SRS/273583415721?hash=item3fb2d7a1a9:g:v4oAAOSw~llb~jJa
my reader has a lot of software problem such as very slow, you feel it struck when too slow, showing you obviously wrong data in many places (live stream data), live stream graphs are not good. Hope they have improved in the last few years. One best thing it did to me is it read the ABS sensor code, telling me my front-right ABS sensor needed replacement while my other two readers just showing no fault code. Good luck!
are you sure you have n42 engine? I have n42 and my sensor looks completely different it has narrow end. the one you have doesnt even fit there
1. Yes, my engine is N42;
2. Yes, you are right! the original sensor came with the car has narrow end! But if you buy the new sensors, they will have the shape as shown in the video. That indicates that your sensors haven't been changed.
Have a good day!
@@RepairDIY i bought today the one you have and i couldnt fit. Should i press more inside i was scared to get it stuck
@@747bender
1. put more oil on the o-ring.
2. you could try to put the o-ring at the front-end of the sensor so that the o-ring can seat early.
3. you could also try to put the o-ring into the position at the recess of the sensor hole in the engine, then try to put the sensor in.
It has always worked for me with these three methods. good luck!
@@747bender Important: you can first try to insert the sensor without the oring. if you cannot insert it in, that means your sensor may be too thick? otherwise you could try the three methods I just mentioned in the previous message. good luck
@@RepairDIY thank you very much, i will try but if you say that sensor may be too big, how is it possible? cause nobody mentions the diameter of the tube on the web.
Thanks, this really helps a lot.
Would you mind confirming the replacement part numbers you used?
Purchased myself FEBI BILSTEIN 23799 part and not 100% sure if it's intake or exhaust... Need to buy a second one now but don't want to make a mistake and get identical sensor again.
Thanks again
hi,
the old part number from the part removed from my car: BMW 7 506 273
the current part number should be: BMW 1214 7 518 628
I think the intake and exhaust sides use the same camshaft sensors.
check compatibility and compatible BMW part numbers before buying or ask the sellers to confirm. Good luck!
Great, thanks. I found it myself few minute before you replied :) Those do appear to be identical! Thanks for taking time and getting back to me. Much obliged.
Hi both, can you guys confirm whether they're the same part for both exhaust and inlet?
Looking to change both of mine as I've got a bit of a rough idle every now and then and triggered an inlet cam code.
Hi Michael, yep - both are the same part for N42 engine. Replaced both today in my E46 and it works flawlessly. I think it's different for the M5* engines, though, so keep that in mind if you have one.
Yes, the same old part number when removed for "N42" engine.
I get fault codes on BOTH, I took them out, and cleaned them, and then the EML lamp went away for a while, I then drove about 250kilometers with the lamp going on and off , without turning the car off, and without loosing any engine power, next day, impossible to start it, both EML lamp and engine lights are back on , and even ABS / anti spin went on , but then off other times when I tried starting it. The car is using a lot of oil, and its really "guggy", the car doesn't use any water / coolant. I couldn't either fit the new sensor in, its to big comparrised to the originals one in the car. got error code : 2782, 2781, 27C1. I don't know what to do.
hi, based on my own car, you could consider the crankshaft sensor (for not starting) and oil pressure check? The new camshaft sensors look bigger than old designs, but they have the same diameter at the base so no problems for my installation. Good luck!
Hi @medisin6rs, I just cleaned mine and I saw a tiny crack on one of them. They were probably too old and the temperature made them crack. The result is that the oil goes inside the sensors....
If you see the wires covered of oil, you know that the sensors are cracked. I would suggest replacing them.
My car has no fire. doearning.com/?id=2846 2002 318ti: I was told it would be a faulty crank sensor so I changed it and still, it wouldn't start. Pulled from scanner (p0341) could it be cam sensor causing no spark ?
Hi, a bad crankshaft sensor definitely causes stalling when warm, and even no sparks (no fire) if very bad. a bad camshaft sensor normally allows the engine to start but poor idling and rough running. to start an engine, you should have a good enough crankshaft sensor, sparks and fuel delivery. You could check if the fuel pressure is fine at the pressure check valve on the fuel rail after you put the key to the ignition position for several seconds (you can hear the fuel pump running and then stop). good luck!
Your cam sensor looks smaller than mine I'm having trouble finding the right one
in UK, I always check car parts on eBay, GSF and Eurocarparts. Good luck!
Annoying change mine stil getting the result an faulty still bot starting
Hi, if not starting, I suggest to check your crankshaft sensor. Good luck!
