Any one done this timing chain tensioner job on a 2004 E53 D-Sport ?

I'm guessing the whole front of the vehicle probably has so come off ??

Any one got a diagram or instructional for this bob please ?

Have a look at newtis.info

Copy of the official instructions for many BMW cars.

Specifics should be amongst this list.....

Start with the M57 link as it covers all of the other areas - such as timing cover removal.  Special tool links are also on the relevant pages and show you what you either need to get or make an equivalent of 

Hi D-Sport Sir,
I peeped at the gimpf for removing the cam chain cover....
My God, half the car has to be removed to do the job, & i only need to replace the hydraulic tensioner...

The hydraulic tensioner is under the top of the timing cover, so I had this idea of chopping the cover so remove just the top 1/3d to replace the hydraulic tensioner, then refit/rebolt this chunk of case cover & seal it back up... job done..

My X5 is old, 190k miles on the clock & tthe strip down to base parts for the hydraulic tensioner will write her off...

Penny for your thoughts ??

Update,

I like the idea of cutting the timing cover panel, not having to strip half the engine down, & then replace the hydraulic tensioner on its own.
I have this goo in a tube called STICKS-ALL & this will re-seal the join in the timing cover effectively.

I have a dremel with a 1mm cutting disk, that can potentially trim the timing cover without touching the guts underneath with the aid of a vax vacuum cleaner to remove the particles from the cutting disk.

The theory sounds good, however, the tension arm/strip may be broken, not just the hydraulic tensioner failed.

If any one has any ideas or input re chopping the timing cover, I'd like to hear it.
We will soon see.
