Vanos Solenoid Replacement

RickZ4 · Post by **RickZ4** » Fri Oct 19, 2018 12:17 am

Hi,

I’m swapping out the solenoids (N52) this weekend and have been watching the usual YouTube vids for this simple procedure. The process is described as wipe the hole with a rag, shove in the solenoid, and screw up tight.

Are there any finer points they have missed such as a recommended torque setting for the bolt? Should it be replaced or greased? Any other comments appreciated.

Thanks.

I’d replace with a new bolt, same as recommended when changing the water pump as the magnesium block can react badly with corrosion

I think pretty much as simple as described. Personally i’d just reuse the existing bolt and apply a little engine oil on the solenoid o-ring before fitting.

Thanks for the advice. It was very easy to do on the N52, even though you can't see much...

Is there a particular trick to getting them back in? I cleaned mine recently, and it was the lords work getting them back in, getting the O ring to go back! Through the little gap between the radiator and engine I couldn’t really get the force!

I'm pretty sure I could get mine back in by hand, but you could always use the bolt.

Did you smear the o-ring with oil? if that doesn't help try fitting the o-ring in the head first the solenoids seem to have a chamfer that would help but the hole in the head doesn't. I've got a pair of new solenoids to fit I'll let you know how I get on

Rickz4 what issues were you getting in order for you to decide to replace?
