Hi guys,

Got a ticking rattling noise around 2500rpm. Is this a vanos problem (see video)? Any idea if its covered under BMW CPO warranty?

Anyone?

dunno but have you checked your DISA??

Yup checked it looks fine thnx!

If you have a CPO warranty then i guess the dealer is your first call to make, i'd be surprised if it wasnt covered. Dont try to work on it or fix it yourself if you have a BMW warranty, let them have the hassle.

Let us know what it turns out to be and good luck.

Thnx, i went to the BMW stealer today. The first guy heard something but then somebody else came. This guy didn't or pretended that he did not hear anything, i drove around with him for 20mins but he said he could not hear anything unusual.
I told him that i was clearly hearing something rattling that does not sound right, he told me to make a appointment so they can have a look at it. Appointment is set for next week.

On the way back i clearly heard the rattling when i drove home with the ac and radio off. So i went to a independent garage which always helped me out nicely and asked some guys over there to listen, it took them 2mins and they told me right away its a vanos problem.

So my question is what am i going to do next week if they say they don't hear anything wrong?

Thnx guys

I wouldn't take no for an answer, I would visit another dealer and explain the situation to them an get them to confirm the fault. You have to be persistant with some garages otherwise you wont get anywhere.

I recently replaced my Vanos oil seals with the Beisan made seals, it was nightmare of a job thanks to my own stupidity but I recon my fuel economy is better by 2mpg and the performance has smoothed out.

I hope you get it sorted soon.

Update:

It didn't feel right how the dealer talked to me about the engine noise. This morning i went to a different BMW dealer and i have to say there services was excellent! Had all the time for me.. i even had no appointment. Drove around with the guy and he heard the noise as well! They had loaner cars available and time to look at my car.

It can be a hit or a miss with dealers unfortunately, now that you have found a good one i would stick with them in future. Any word on the problem diagnosis?
