Buying cam sensors, whats all the fuss about?

Post by DanHolman » Fri 26 May, 2017 08:33

£130! That's the price for one genuine cam sensor from BMW, or a very reasonable £30 from my local reputable motor factors? I've got my friends dad telling me I'm an idiot to even consider laying out £130 for the oem one.

Can I get a vote on it? Anyone successfully replaced theirs with one from a decent motor factors?

No. Do a search and you'll find plenty of stories of people fitting aftermarket ones, then buying genuine ones. Get your friend's dad to promise to reimburse you for the aftermarket one when it doesn't work properly if he's that confident.

That is a convincing No. Darn I may be in for £130 then...

I would just like to add; could the stories of aftermarket cam sensors woes be misleading? How do we know that people are buying them from a reputable motor factors like PMA or a Chinese knock off from eBay???

I sense I'm clutching at straws

Oh Well, As my first girlfriend used to say; quality is better than quantity.

Maybe, so total cost will be £160, and job being done twice.
Some things of BMW are not the best, and don't last long so aftermarket is good,, but if they have been on for 20 years before a problem then an original is a good idea.
Anything sensor wise is usually a good buy from BMW as it rules out a recurring fault leading you down a path of 'it must be something else then because I changed that a month ago'.

I have an element of 'M-styling' on my car, If that's a good enough reason for the manufacturers to adorn a 320 with the M badge, then its certainly a good enough reason for me..

What makes you think you need a cam sensor anyway?
Before you spend any money make sure the one you have is faulty.
If you are relying on a cam sensor fault code the actual fault on the car may be something else for example an air leak at the intake bellows.
Check the easy, and free, things first before condeming the cam sensor.
Once you have decided you must have a replacement sensor buy a BMW one and do the job properly once only. As gookah says you will regret fitting a £30 sensor and you will ultimately buy the BMW one after a short period of time.

Inpa has given 112 phase sensor; value unplausible. The logic counter is at 40 meaning the fault is very recent.

The pattern of the fault suggests it's definitely electrical; infrequent, frequent then almost dead is consistent with sensor failure I've seen it before on another car.

I've been getting intermittent 'crank but no start situations' which are getting more frequent, in fact it probably wont start anymore. I think it would make more sense if it was the crank sensor, but both my inpa and my c110 scanner say cam sensor. Well c110 gives cam and inpa gives phase.

Other symptoms- lack of power but that was with cold engine immediately after start up going up a hill? plus slight hesitation very infrequent.

Hi, here in Australia we have a couple of supplier that sell OEM products [same manufacturer] but don't have the BMW stamp on them. These parts are same quality and usually 25-50% of the BMW stamped product. However, if you cannot verify the quality it is best to avoid the products as mentioned in several posts above.

first of all, hello to cooper01 in Australia- no less,

Well, by a majority it seems that the expensive BMW OEM cam sensor has won the vote then.

As my first girlfriend used to say, 'You appreciate quality long after you've forgotten the cost!

Thanks all for the input.

Lucas would have been an acceptable make as would oem made by Bosch or Siemens, its the cheap Chinese ones you have to avoid.
