M roadster vanos service
Hello, I have a question regarding the vanos unit on a s50 2000 reg with 40000 miles on the clock.
Is it worth having the vanos unit serviced? If so at what cost?
Many thanks

Not unless there is something wrong with it? The old saying of 'if it aint broke dont fix it' applies
The only 'servicing' you can do is replace the vanos filter every inspection service. Its the size of a 10p coin and costs a few quid.
Other than that make sure you use the correct oil on services and check to see whether your vanos bolts have been uprated (ask BMW), if not do it sharpish

vanos
The trouble is with the saying "if there is nothing wrong dont fix it" is, do we really know there is nothing wrong. I have been reading on bimmerforums about the vanos noise and rattles, some say it is normal, but if it is normal how are some M`s quiet and most others noisy. Surely a noise means the vanos is not working properly and needs attention. I have bought a set of seals and gaskets for mine but i am sure it won`t stop the tick or growl and people have had new one`s fitted and the noise has come back. What do we do

oil
Hi Badman g.
The M is fabulous -and was told by a top engine expert who once owned the car previous to the previous owner only to use Castrol Edge 5w-30 as the other thicker oils like 10-60 arte too thick for the vanos. That oil is in my car now and have purchased the castrol edge to replace it. The vanos has only just started making a noise as i have not used the car since i bought it 2 months ago i am not sure whether its a lack of use noise.
does mr vanos still operate?????

Re: vanos
No it most definately wont get rid of the growl. Replacing the Seals/gaskets with proper viton/teflon seals will stop solenoid failure. OEM seals are weak and cannot cope with the high pressure of the oil. Solenoid failure will result in a car with massive lack of performance, bad idling and such laggy response you end up fighting not to stall the car. This IS the problem people report of VANOS failure, there is no warning..none whatsever, I've learnt this first hand when I bought my car with a SILENT Vanos.hornel Z3M wrote:The trouble is with the saying "if there is nothing wrong dont fix it" is, do we really know there is nothing wrong.

The other known VANOS issue is down to the bolts which have now been recalled, if your car is running original bolts they can (and are known) to sheer off resulting in 7 liters of oil being dumped at an alarming rate into your engine bay and all over the floor...obviously oil starvation can then destroy your whole engine if not switched off quickly, i've seen too many threads with this happening not to get the bolts checked and possibly changed every inspection II Service
The rattle on the other hand is the fault of the splined gears, they were designed with very loose tolerances so can start to develop a rattle/growl. This has NEVER led to a failure as far as i'm aware, show me a thread and prove me wrong. Also as mentioned in a previous thread my brothers S50 has no performance loss at all and has a slight growl, the splined gears being slightly loose does not stop the VANOS from functioning properly. If you are keen to get rid of the rattle you will need to have your VANOS completely rebuilt and as you said yourself its likely to return
I hope I havent just instilled fear into you but its better to know what to do to prevent problems from occuring

web
He`s on the web but i failed to get an e-mail on his site to him and have have phoned, admittidely out of hours but no answer phone so i am not sure The seals and bolts prevent the oil loss and bolt shearing and can be dony by a competent person but i want dead quiet from my engine if you know what i mean so that will possibly not quieten the vanos
Re: vanos
This is true i was told by a independant that most people renew the vanos and dont renew the splines because of the extra costshantybeater wrote:The rattle on the other hand is the fault of the splined gears, they were designed with very loose tolerances so can start to develop a rattle/growl.

"False economy"

I stick to AutoGlym products for all of the above, they have never let me down.
The glass polish works well on the rear window as well
Check out the link in my sig below for my progress thread, i did a detailed clean and posted up about it at the beginning of it

polish
Find some Meguiers polish and car wash and some leather cleaner for the seats the back window can be scratched with the wrong materials so just clean with some window cleaner and buff up.. The wheels on mine never get dirty so i just polish them up with the car wax,,, no car cleaner than mine
Re: web
I spoke to him about a month ago when I was enquiring about refurbishing the vanos on an M5 so he was around then.hornel Z3M wrote:He`s on the web but i failed to get an e-mail on his site to him and have have phoned, admittidely out of hours but no answer phone so i am not sure The seals and bolts prevent the oil loss and bolt shearing and can be dony by a competent person but i want dead quiet from my engine if you know what i mean so that will possibly not quieten the vanos
