Having thrown an intermittent code for a stuck / jammed exhaust VANOS... I scoured E90Post for information. Many threads said to clean the Vanos and put it back to use. Done. That lasted a few months. It went again. This time, I swapped it with the intake solenoid to check out there was nothing else going on. When swapped, the intake solenoid was fine on the exhaust but the exhaust one threw the code as stated...
At 100,000 miles and 8 years old I took a punt on replacing both... usually replace things in pairs anyway, like brakes for example so thought why not... The result... My gosh...
Would you believe that three dealerships did nothing... even my independent mechanic thought the vanos was fine but the car has completely and utterly transformed. The difference is night and day. I think at 110k miles I will look into the DISA... but I am budgeting for new front arms as they are due for a replacement and I would like to put on some Meyle HD arms. I think the o/s/f shock may also be out... it has seen one too many a pot hole. |

This was one of the first things i did on my 2.3i E89 when i bought it - felt much better. Am thinking about doing it on the 335i but it's way more of a b1tch the try and get to the solenoids!

How much did you pay for the solenoids? I assume you sourced them from a dealer..?

You cannot swap on my one. It is a 325i (2.5) version. If you have a link to the M3 front arms that would be appreciated. I came across one kit... M3 arms and Meyle HD bushings but it is from ECS but you can imagine how much it would cost to import.

Phil they were £72.16 per unit. I ordered them from Cheltenham BMW. You get a 10% discount for being a forum member and free delivery over £50. My headlight washers were due for replacement as they were leaking so I thought... once I have the bumper off I am going to do all the front things like the lux angel eye install, vanos (not that the bumper needs to come off for that) etc.

I got my M3 arms from here: https://www.rexbo.eu Part numbers are JTC1423, JTC1424, JTC1426 and JTC1427 You can try other places to see if anywhere else is cheaper, prices fluctuate a bit, sometimes amazon has them for a good price. Not sure what you'd need the Meyle bushes for, on the front end the only other parts you might want to change are the ARB droplinks, top mounts, and track rod ends. |

Having said that mine is a two stage. Double vanos, valve tronic, two disas and having been on the NA forums some have said just because it has two DISA doesn't make it a two stage although there is a plugged hole where the third DISA would go like on a 3 stage. No one has ever attempted it on here. I wonder what I need to do to make it work. It already has 218ps out of the box which is not bad. The rev motoring silicone intake hose and k&n filter have bumped that up to probably 222ps or something - although rev claimed gains of 12-14 in the deleted thread. The plan is to get a remap to improve drive ability even more and may be see it to 230ps. I know there won't be massive gains on an NA engine. If I hang on to it... Next year I will stick on a wave trac lsd but it all depends on how it performs this year. Even toyed with the idea of an ess kit but that will be an issue of saving up. |

I bet mpg has increased slightly as I don't have to give it too much gas now to get going or when accelerating from say 30 to 40 it has a new found urgency. The pedal is more responsive it seems and I can actually tell at times when the vanos is fully active a bit like a friends Honda Civic v-tech. The point of it all is that when you clean a vanos and clear a code that doesn't mean the issue is resolved. In my case the code cleared but their was no improvement in drive ability and how was I to know? It had always been a bit of a slug off the start line since day 1. I thought it was one of the features often 'underpowered' 2.5 litre car as it weighs a tonne or two and then some. I even read threads on this forum of how the 2.5 is like driving while towing a jet ski permanently attached to the back... but really isn't and this is the true car! Having come from Audi S3 power levels this is quite capable and very sufficient for my needs. Thankfully the bearing ledges showed very little wear and tear. After a remap in a few months time I intend to take it to Surrey Rolling Road.

From the sounds of it the 2.5 version isnt as crippled as the 3.0 version then, its just making less power due to the capacity.
218ps from 2.5L is equivalent to 261ps from 3.0. So the manifold isnt really holding the engine back unlike the 3.0 version. |
