Someone will link you to the “TIS” setting book/sheet shortly I should imagine. I think I’ve seen it on here before. Why did you have the cover off?

Might take the carbon fibre cover off and replace with the original. Bought a brand new badge or the cover from bmw so going to put that off the carbon one onto the original. The carbon one has slight bubbling in the top layer doesn’t look bad but I want it to look perfect. If I do take it off the cover will be up for sale for cheap if no one wants it I’ll put it on the wall in the shed pubstevo///m3 said:

And now they are saved in my phone!
On a different point would love to try and get as many of the m coupes together this year and twist tomscotts arm to do some photos. Mainly to drool over your intake! But to have them together just for a bit to get the photos in the history books!

There are I think some small inconsistencies in that document.
For instance the torque angle on the bolts of the reinforcement plate under the engine is 90 deg, not 90deg plus 30 deg.
90deg + 30deg is only for cars that have an reinforcement cross, not a reinforcement plate. In the document it is picted with the plate.
At least thats how I understand the way bmw intended it.
I think the difference is in that the cross is much thicker (so that bolt might also be longer) and as they're stretch bolts it would take a bigger torque angle on that cross to achieve the same stretch force than with the thin aluminium plate (which has 2 bolts there also)
But its quite a big differenct to torque something an extra 30deg or not.

BMW TIS has for the e46 chassis both the procedure for the reinforcement cross as the reinforcement plate.

Picture of a somewhat more degraded version :lol:
e46 m3 with the plate at the underside:
Video of an e46 m3 underside (totally done up, a feast for the eye)

I have no idea if there are different verions with plate or cross or so (I dont even know if there are any e46 m3's with the cross, if not, it would be incorrect, otherwise an inconsistency I guess). All I know is that they need different tightening torques and thats what caught my eye, because its on the first page with pictures (I obviously havent checked the complete document, but on the first picture page there is an apparant inconsistency)
But the z4/z4m have a plate there, needing 59Nm +90deg on new bolts.

TIS has procedures for both parts listed for the e46 m3:
TIS has entries for both the cross and the plate. This is from the official TIS program as BMW made it. (mine's in dutch but I'm sure the german or english one is the same)
RA3111005 is for the cross, RA5171374 is for the plate
The cross is 59Nm plus 90 plus 30 deg, the plate is 59Nm plus 90.
I always use TIS because of inconsistencies like this.
TIS does sometimes list parts or procedures that are not present in the car you're working on, but the picture I placed clearly shows that there are in fact e46 m3's with the reinforcement plate (if there are any with the cross I dont know).
Using 59Nm plus 90 plus 30deg on the bolts on that plate would not be correct the way I interpret TIS. For the procedure with the plate, TIS states that torque settings 51 71 3AZ should be used (59Nm plus 90)

After this conversation I will endeavour to do so more sir! All to often I find myself too lazy to read through tis and just get some random torque settings off the internet, luckily I rarely attack too much near the chassis.
Not that the braking system and engine are any better places to start mis-torquing things :lol:
I always have a laptop or tablet handy with tis. Just point and click and you have the exact repair notes there with all the torque settings, pictures, tools to use etc etc. I can't think of a better and faster tool to use.
Especially a tablet is handy. Tis was designed to be used that way. Thats why all the buttons are so large, its a touch screen interface.
Its one of the reasons why bmw's are nice cars to work on. The software is very good compared to a lot of other brands, easy to use and a lot of information.

Indeed, I appreciate that, presently I have mine on a very old laptop that has little or no charge and needs to be plugged into the obd port in order for tis to work (and I have a crappy 30cm or so cable... cheapskateGuidoK said:
). I'm sure there's a better way round it than that and I really should junk the laptop (or get a new battery 
).Someone posted this link on here a month or so ago which I've found useful, an online tis 8)
