Not a Project but...

I've also fitted the new MAF today. Instantly knew it had worked as the maf read 0.0 kg/h with the engine off. Its a VDO unit from autodoc so probably a bmw part without the stamp (half the price of the stealers price!). I did some checks with my torque app and hey presto! The MAF reads and gives reasonable readings:

So it seems the P0102 code this time was a faulty MAF. No need for the smoke test but I enjoyed making the machine and it's peace of mind that everything is buttoned up (also useful for the future).

P.S. I can now heel and toe .

Almost a month since my last post and I've done another 250 or so miles. The engine is really strong, infact it feels stronger than it should be. I'd always thought the throttle response was pretty sharp since getting the car and when I press the sport button, nothing happens. I've done a little research (a little knowledge can be dangerous) and it could have been coded/mapped out. Is there any way to check this (apart from the obvious hold it at 25% throttle in third and press the button to see if it livens up)? Or is there any way to check if the button is working? I now have a C310+ and have looked into thr odes but nothing seems to be blazingly obvious that the sport button has failed (although this could be my limited knowledge of which codes would show this).

One thing I have noticed now I'm able to give it the beans is that the brakes are needing some attention/upgrades. Back in the day when I had my Cooper S EBC Yellow Stuff pads were the pads of choice but that was a loooong time ago. What are folks using now for a decent road pad that isn't going to send me out of a T junction before they've warmws up.

Not sure you can 'code' the sport button, but maybe it's had a remap? I believe they can do it through that?

It does have a K&N panel filter so potentially someone was looking for some performance. Is it possible to check the map with a C310? I'm guessing I'd need something a little more powerful to look at the tables in the ECU?

I doubt it? I'd think you would need a remapp-ist to tell you.

Ah, I don't know any friendly remappers. Might have to park this investigation for now.

One thing that is slightly annoying is that it seems the steering wheel, or at least the airbag, has been off the car in the past as the bottom spoke of the steering wheel is loose. I didn't want to press it in the hope it just clicks back together but I've tried looking for steering wheel disassembly videos on YouTube and not found one where they show how the bottom spoke comes off (they all gloss over this part). I'll try and post a video tomorrow but if you know of a video that shows this then it would be good to try and get that back together. I don't really want to take the airbag off if I can help it.

Torx screws on the rear, but they screw into plastic on the front section which easily snap.
So try squeezing front and rear together while tweaking the screws, but you may find the damage is done.
If it's a standard wheel I can maybe help.

I don't think there any torx screws in the back as the holes feel clear. I fear you might be right about them snapping. I'll try and get a video tomorrow and post it here. Do the pieces just click together? They don't slide into a groove at all?

[enuff_zed]

Click together but the lug that the screw goes into pushes through a hole in the spoke. So if they are broken it may not locate securely

snapped front unit threads. Itdoesn't affect anything but I sometimes catch my fingers on the edges.

Can these pieces be taken off with the airbag in place?

[enuff_zed]

Can these pieces be taken off with the airbag in place?

Possibly, but not easily as they fit under the edge of the airbag. Twisting to get them out may cause more damage.

The trick to remove them is to undo the screws and pop the rear part off using a trim tool to separate it from the front part.
Don't try to prise the front off as that is what snaps the lugs. Use a parallel punch or something similar, same width as the plastic lug, and tap the lug back through the hole.

It looks like this has already been done (you can just see the lighter plastic on the photo where the lug should sit). Might be on the hunt for some steering wheel spokes.

Car threw a little wobbler today. When accelerating the car just sort of cut out/bogged down. There was no codes or flashing lights today. Yesterday it did it twice and one of the times the traction control light flashed. When I got back after driving I thought there was a ticking/clicking from the engine bay but I didn't hear it this morning. In the last tank I was using 99 Ron fuel but had to put 95 Ron in at the weekend. Surely the change in octane rating wouldn't mean it would bog down or cut timing? I thought the ecu would just adjust the map accordingly? Either way I'll see if it does it again on way home.

If you do need a set of spokes I may be able to help. I have a complete steering wheel but it's not the best so I could see if the spokes will come off cleanly.
Regarding the car bogging down and getting a traction light, it could be a sensor thinking a wheel is slipping and cutting in the traction control which in turn cuts the engine output.
One of the ABS sensors on the wheels; one of the rear reluctor rings starting to corrode or with crud in it: bald tyre so it is actually slipping; yaw sensor; broken spring; knackered shock absorber; broken rear ARB drop link...............
That should keep you busy for a while.
Did you do a full system scan? I've now had two cars where the DME has had a 'RAM Error' code and caused similar symptoms. Fitted a new DME and did the EWS delete on it and all good.
