Good Afternoon fellow fanatics i trust you are all well..
I am in need of your guys help, my dads car is seriouly acting up it's a E90 325 and it keeps miss firing and it's very under powered. he had the car serviced and he replaced the vanos and after that it pulled strong but two days later it was back to sqaure one.
Please help guys all help is appreciated.

Hi Bud, I was at Ross Duncan in Midrand the other day and he said the most common problem is the actual Vanos filters which get blocked up and it’s not the Vanos unit that fails where about are you based?

 

[KarshS]

same problem here.....

Also had the vanos and stuff replaced...

Goes in to bmw, acts fine for about 3 days and its back to normal.

It has been at bmw for 10 visits in the past 3 months....

Issues definitely seem very very similar!!

A stack of things can go wrong; varying from sensors, to leaking inlet manifold to even a broken bolt on the crank shaft puley, affecting performance.
Start with a diagnostic for about R250.

Bad plug, or perhaps a coil pack? Misfires will show up in the diagnostic test.

Hey guys firstly i want to apologise for the delay.
Secondly thank you very much for all the replies.

@frikkieh the car is in abd out at smg and i have no idea what they do to it because sometimes it's there for 2 to 3 days and they don't say that they pick up any faulty codes and we did have them check plugs and coils.

@v.r.sexy6 i think you and my dad are experiencing the exact same problem and i feel for you on this one really it's frustrating aas hell.

@Nikhil thank you for the fast reply i'm based in CT buddy but i will be looking into that.

Guys i just want to once again thank you all very much for the replies hopefully this issue will be sorted because it's the really terrible:argh:

hey v.r.sexy6 the car was at SMG and they just said the vanos needs to be replaced so the whole unit was replaced but after that it was ok for like 3 days and then it just went into slow mode :bangdesk:
but let's see what happens after the coils and plugs are replaced
I'm seriously hoping they get yours sorted because i know what a pain it is..
holding :thumbs:

 

[alleng]

I had the same issues on my E90 325i. After 3 frustrating visits:-
1. vanos valves cleaned - no joy
2. oil short, filled up still no joy
3. turned out to be the lamdar sensor

All the best!

New vanos fitted last week thursday.....

Proplem not solved.....Still have to switch off and on again to get rid of the flat spots...

I am now thinking it might be the coils....

Hey Tareeq,

What do you mean by misfiring? What I've been experiencing the past year or so is when when my car idles, the idling is not smooth. The rev needle tend to take a dip, as if the car wants to switch off.

Is this what you're experiencing?

Thanks

hey sorry about the delayed response it's exactly like v.r.sexy 6's problem on cold start the car has a flat spot and then you i have to switch it on and off again and sometimes while i drive then it will missfire.
It does dip now and then.

 

[A B]

Mine drives fine but the idle is not smooth. Booked in a couple of times but they never seen to experience it when they test the car.

I'm beginning to wonder whether they know what to check.
