    I’ve just completed my SMG To Manual Conversion on my E46 M3 Coupe. Pictures Below.

    I know some of you may think why i’ve done this or which is better.

    This is not about what is better or who prefers what. It’s down to personal preference, i’ve own my SMG E46 M3 for 5 years and during that time I loved the SMG (I was driving around 200 miles a week for my job, with start stop traffic).

    For the past year i’ve been working more from home more and therefor only use the car really on weekends. For the past 6 months i’ve always been itching that I want a manual again.

    Therefor I decided I wanted to make the change. I’ve never driven an E46 Manual M3 (which maybe anyone thinking of doing this should in case you hate it). Now I did not do this conversion because I was worried if my pump breaks or the SMG packs up as mine was working flawlessly prior to the conversion.

    Now some will say why didn’t I sell mine and get an Manual? I’ve spent a lot of money on this car since 2011 on maintenance which includes full Vanos Rebuild, New Discs Pads All Around, New Starter Motor, New Alternator, Steering Hose, replacement backbox, new exhaust hangers & countless other items.

    Not to mention it’s an Individual Estroil Blue With Two Tone interior and has every single option (apart from electric blind). Which at the time of purchasing, taken me a lot time to find the right spec and condition.

    I’ve done the whole conversion myself from start to end, which includes the wiring, and the programming/coding side

    I’ve never done anything to this scale on a car. I’ve rebuilt my Vanos last year which I found fairly easy (although time consuming and a lot of research). It’s taken me 6 weeks to complete which i’ve done in the odd hour here and there between my day job.

    A lot of time is wasted figuring out how to remove stuff such as the gearbox or how to access certain bolts or rebuild the gearbox, how to code the car etc ) (I used NCS Expert & WinKFP BTW)

    In total the parts to convert cost £700 and labour was free because I done it).

    I’ve purchased a broken E46 M3 Manual gearbox off eBay for £165 (it was crunching gears apparently). I only wanted the bellhousing from it. I knew my gearbox is in perfect working order (will have little wear as the SMG is doing the perfect changes) rather than human (who can crunch gears in).

    I changed any wear and tear parts that needed to be done whilst I was converting, so as the Flex Disc, CSB. Exhaust Brackets, bolts etc, Gearbox and Diff oil change, so i’m not adding the cost of these parts to the conversion as they needed doing anyway.

    I used the F10 M5 Manual Weighted illuminated gear knob which is one piece with the leather. I had to cut an old E46 leather gator to use the plastic frame for the M5 Knob. This alone cost £120 but It’s well worth it. I decided to use the 545i E60 shift lever for the Short Shift rather than 330d as it sits central and feels bit better to me.

    Everything is Genuine parts, brand new Shifting linkage Bushings, rubbers etc. Feels like a brand new the shifting.

    How does it drive or feel you ask? Well i’ve only driven it for 10 miles and I love it. It feels like another car. Hands down it’s the best Modification you can do. It does feel much more engaging to drive.

    Everything works as it should no limp mode or dash errors, PDC, reversing lights.

    Hats off to you mate. Looks like a terrific job. Keep the spare parts incase you change jobs with more miles and have to change it back.

    Any more pics of the two tone interior?

    Cheers everyone.... I know it would have been easier on Ramp, but i used high lift Axle Stands which made the job so much easier, they lift up to 75cm.

    I have kept all my old parts safely stored In case I really don't like and can change it back next clutch change (which I doubt really I will)

    Just need to code the DME for cruise, it's all wired so it will work after. Just coded all the modules such as DCS, Cluster etc.

    Here is my interior.

    I didn't add the Gear Identification sensor as it's not needed, the Guys on M3forum have figured out a way to code the DME so it works without it. You basically wire Pin 2 from the Clutch Pedal Switch Directly to the DME - X60002/Pin 20

    Then you need to do the following to the ECU DME File:

    Set: K_SKRAFTS_CONTROL to 0x02

    Located at: 0x4028

    What this setting does is:

    The DME cannot differentiate between an open clutch sensor and an open Gear Identification Sensor since they're wired in serial. This system works basically the same way on the E46 M3.

    With the clutch switch wired directly to the dme without the Gear Identification Sensor in the middle. This change makes the car understand that the circuit can be closed even in neutral with the engine on.

    This is how Z3Ms are wired and coded from the factory.


    And

    Set: K_S_GANG_LL_ED to 0xFFFF

    Located at 0x35AC in 1701

    What this setting does is:

    So when the car is idling with the clutch up, it doesn’t thrown an error

    Love it! Hats off to you sir!

    I have a manual Estoril Individual fully loaded with full grey leather. and I'm planning on a black dash and carpets to match your interior!

    Nice to see what it'll look like.

    Good work. I have a manual but I used an SMG box when replacing my box due to synchros going. It's nowhere near as hard as people think and I worked it all out myself as couldn't find a guide. Did you tap for the reverse light switch?

    You could sell the SMG pump which will fund half your conversion aswell

    I know I could have got used working manual gearbox but always a but sceptical of synchro condition. No the reverse light is the same, nothing needed, some people who have converted tap the gear identification sensor where the blind plug goes, but that is not needed at all. I know I wanted to hang onto the SMG bits in case I hate it which I don't think I will, also I have new motor on my pump so yes it will recover most my costs.

    FairPlay to you, how hard was the peddle box to fit? Was looking at this myself before fixing my smg, have learnt to love it now though

    Cheers, do you mean the actual clutch pedal? Well the hard pipe that runs to that was one of the hardest parts of the conversation as for some reason on RHD cars it has to routed over from the passenger side as there a grommet in footwell.

    So I had to remove the front carpets, and because it's hard pipe, trying to guide it under the heater matrix was very frustrating. Someone suggested I use a flexi SS line, which yes would of made life a lot easier. The physical pedals installation is plug and play, 10 minute job.

    Yes I did fix my SMG pump last year with a new motor.. So they car was running flawlessly, I did even have the CSL and Rev Matching done, but even then, always felt someone was missing..

    Next job will be full back end rebuild including: Subframe reinforcement, all new bushing etc and underside re seal. That will be fun.
