2.0 Exhaust manifold removal

Post by Cooky675 » Wed Oct 05, 2016 9:37 pm

Hi All,
New to the forum and after some advice please...
I have a 2007 2.0 and have the seemingly common fault of a blowing exhaust manifold. I have a mate who is a dab hand at welding exhausts so thought I'd whip it off and let him do his thing.
Problem is I have all the fasteners and connectors removed but am struggling to get it out of the car! Anyone had any experience? Please tell me I don't need to remove the steering column!!! Does removing the mid section of exhaust give enough room?
Any help much appreciated!
Cheers,
Matt

Hi,

Did you manage to remove the manifold in the end ?

I'm in the same position and grateful for your update

Thanks

BMW TIS manuals are your friend with stuff like this, you can buy the disc for a few quid on line or is available on the web via google.

Necessary preliminary tasks:
•Remove engine splash guard.
•Remove reinforcement plate.
•Remove exhaust system.
•N42 only:Identify plug housings of control sensors for
cylinders 1 and 4 and 2 and 3. Unclip plug housings from retaining fixture.Disconnect plug connections of oxygen sensors.Release nuts, remove exhaust manifold from cylinder head
Re-installation: Clean sealing faces. Replace seal.Install seal so that lug (1) points to exhaust manifold.Coat stud threads with copper paste.Replace nuts.Tightening torques per TIS.
Assemble engine.Check function of DME. Important!Ensure sensor cables are exactly routed

Unfortunately I cant get the TIS page to load here as a link but the address is, hopefully it helps :thumbsup:

Ewazix,

Thanks for your reply.
I have already looked at the TIS for the N46 engine and have done all they suggest.

I cant seem to get the manifold past the steering column shaft. It seems that either that needs remving or engine lifted !

I'll have another go

Just a thought :scratchhead:

The TIS available online appear to have 'US' tags, I'm wondering if the instructions are LHD only where the steering shaft obviously wouldn't be an issue. I've got a full TIS disc somewhere but can't get to it for a bit, it may be someone can check the RHD instructions for you, I'm thinking that the steering shaft may well have to come out on a RHD car.

Ewazix,

I think you are right, the repair guide seems to be for the US. there is no mention of the steering shaft.

If anyone has the UK TIS and can let me know I would very much appreciate it.

Of course when I manage to remove it I will update everyone.
