Are you looking for an APIX1 or APIX2 display? I do have a CarSystems non-MOST retrofit adapter (removed from my 130i while reverting to stock, in preparation for sale) if you're not settled on an adapter yet.

A GS6-45BZ from an N55 vehicle (e.g. M135i) can be made to work. The 45BZ used in S55 (F8x) applications is different (longer bellhousing due to different flywheel setup).

Interesting, though I'm not entirely convinced that's not a documentation error - all images I can find relating to the remanufactured part number have a BZ label. If trying to use a DZ, be sure to know it's coming from an N54-powered car; the bell housing will be wrong if coming from an N57 vehicle.

GS6-53DZ is for N57 (diesel) vehicles - you'll want a GS6-53BZ, though a GS6-45BZ (N55) can be made to work.

Moved to the "Want to buy" subforum.

Should be sorted now, there was a minor configuration issue from the site being moved to new hosting earlier in the week.

The EWS clutch switch start interlock has no bearing on the DME (no matter the tune) and will be enabled by default on US and Japanese variants. It can be coded out of the EWS module easily however.

It's easier done in vehicle (as a few modules are affected) and in-person is preferable in case there are any small wiring issues needing to be diagnosed / resolved. HellBM would be able to assist and are located in Silverdale.

I'd suggest going with a DMF and OE clutch setup for a Sunday driver you want to keep enjoyable. Coding a manual conversion on the earlier E39s is a little more of a nuisance than the later vehicles as you have to deal with ZCS coding strings. You'll need the standard coding tools (NCS Expert, WinKFP) along with Zeko to aid with adjusting your ZCS string; update the ZCS string to remove the auto, write it to cluster and EWS, factory code cluster, EWS, ASC/DSC, PDC (if fitted) and then update the DME to ZB 7539328 (or 7539336 for EU2 emissions standard) and reset adaptions.

If ordering off of the BMW number for the clutch kit (21207587369), the diagrams indicate that pressure plate bolts should be included. In saying that there's no sign of them in any pictures of the LuK kit I can find so you'll likely want to order them too.

You'll also want bolts for the DMF (6x 11227520706) and should consider a replacement pivot pin (21511223328).

Time for another update 😊 Some progress has been made on fabricating coolant lines. The current intention is to use an E39 diesel coolant reservoir mounted on the intake side of the engine bay, freeing up room on the exhaust side for the DSC module and vacuum reservoirs. Two aluminium pipes run atop the intake side chassis rail, one for the coolant reservoir to the heater core and thermostat, and another from the radiator to the heater control valve. The next step is to fabricate a hard line to connect these up to the thermostat. In other news, the final exhaust-side engine mount arm has arrived from manufacturing. Test fitting looks good, with only a small shim required on top of the engine mount to raise the mount up slightly, due to there being more compression in the engine mount than anticipated. With that in place, the gearbox mount design was finalised, propshaft angles were checked and the design sent off to be manufactured.

Take a look into the xHP TCU software, it should be able to accomplish what you're looking for.

Thanks Vass, it has been quite a while since I last updated this thread 😊 The car's still going well, no real changes or modifications since the last update.

It has been a few years since my last project (E46 M3 Sedan), and while I'd initially purchased my E39 as a reliable daily driver (specifically not to be modified), I needed something to do a bit of a resto-mod on. An N54 is pretty similar to an M54 though, right? 😁 The subject in question is a 2002 E39 530i touring, purchased in 2018 from a fellow Bimmersport member. Since purchase, I've put around 30,000km on the clock, performed a full suspension refresh (all bushes, bearing, shocks, struts, air springs) and manual conversion. Unfortunately the vehicle was purchased with some clearcoat issues, which have only gotten worse. As this vehicle is still a daily driver, I've also picked up a 2003 520i insurance write-off to use for development / mockup - the pictures below will be of this car. For a donor, a 2008 E82 135i insurance write-off was used. Unfortunately, this vehicle was fitted with an automatic transmission, something I'm not interested in for this project so a GS6-53BZ was sourced from the UK and imported. The underlying theme for this project is "if BMW were to have made it" - I'll be trying to keep everything looking as factory as possible, so no aftermarket BOVs or pod filters. 😀 This theme also flows through to the electrical architecture of the vehicle, I'll be keeping the factory E8x modules (thankfully the donor vehicle came with an MSD81) and aiming for full integration with the E39 instrument cluster via a custom CAN translator of my own design. The vehicle will have fully-functional A/C, DSC and cruise control. The translator I've developed has been proven in the manual HellBM 135d. The first step with the mockup car was stripping out everything not needed: Initial test fitting was performed with a spare N52 parts motor with a GS6-53BZ bolted up: With it generally looking good, an N54 parts motor was made available and put in instead, allowing test fitting of turbos, etc. Looking doable on the exhaust side: Going to need to do something about the rear turbo's coolant line: Enough sump clearance: Tons of room on the intake side: Some shims underneath to get it all lined up: Sway bar at full droop, clears ok: Just need to get an engine mount to join A to B and we'll be done in no time 😉 Bolted up a few more parts, still clearing ok: Starting to work on some mockup engine mount arms so that we can remove the shims, these will only be temporary: Looking pretty tight on the exhaust side: Onto some temporary gearbox mounts: With the temporary mounts made I could then start designing some more final mounts. A 3D print of the design for testing fitment: Same again for the gearbox: The exhaust-side mount ended up being rather tricky, requiring many iterations: Final design of the exhaust-side mount: While that was going on, I took a look at fitting the oil cooler - a factory item on E39 540i's built for the Gulf region: For fueling, I'm wanting to use an E82 135i pump in the E39 holder. The fuel lines will be the factory-fitted E39 M5 lines, filter and 5 bar fuel pressure regulator. Unfortunately, the E82 fuel filter sock won't suit in an E39, so a mockup adapter was 3D printed (in PLA, this will be printed properly in carbon fiber reinforced nylon). Another item to tackle is the coolant radiator, condenser, intercooler and power steering radiator pack. Initially I'd planned on using an E60 535i radiator but found the dimensions won't work in an E39. The E82 pack seemed like the best choice, here attached with some temporary mounts (again, will be 3d printed properly in carbon fiber reinforced nylon): 4 Picked up a 540i rear diff and half shafts, it should handle things a little better than the 530i items: Started mocking up a top cover panel for the radiator: The intake-side engine mount arm machined in T6061-T6 arrived: Fits perfectly: With the N54 having the A/C compressor on the opposite side of the motor (compared to M54), we started working on custom A/C hardlines. This one will run from the E39 bulkhead, around the back of the motor to the intake side, and will have a flexible section running under the manifold area to the compressor: I'm also working on some mounting brackets for it: The next items are sorting out the coolant / power steering / oil line situation which is underway currently. Unfortunately, the supplier sent the wrong size hardline which has caused a bit of a delay on this aspect. Another item we're working on is relocating the DSC module to behind the headlight - the E39 units often get baked in the factory location, leading to failure and other weird issues. The DSC module to be used is a DSC8+ module from a facelift E60 rather than the (unreliable, relatively expensive) DSC5.7 factory-fitted in the E39.

What's written on the top-left of the FRM's label, to the right of the BMW logo? There are multiple variants of FRM2, FRM3, etc, with slight differences in compatibility - for example, an E87 FRM2 in an E81/E82 won't work correctly (unable to learn window limits).

Doing it properly will require resetting the EEPROM and aligning to the mileage and VIN of the vehicle - no need to source one with lower mileage.

CBS (servicing schedules) should work once the VIN is aligned. @HELLBM should be able to assist with resetting the EEPROM.

N46 doesn't have one; it'll need to be retrofitted (PT-CAN to JBE, 15WUP to CAS, power to JB and ground). Make sure to get the bracket as well as the module.

Thanks Kyu; maybe I'll come across a better-suited plate one day. The diff bushes are factory BMW (which means buying the whole rear cover). E46 non-M3 have a slightly different rear bush setup; I'd go with factory rubber personally. Thanks David.

It's definitely firmer than a standard M3, but not uncomfortably so; no excess driveline noise in the cabin or anything of that nature. I've been meaning to update this thread for a while - recent (well, around a year ago now) additions include a CSL airbox (Karbonius). Some photos after a wash a while back:

That's correct; guards were cut off of a donor vehicle (I believe it was actually a convertible - not 100% on that) and were grafted onto the sedan. The inner skin of the wheel arch needs to be extended to match the wider guard. Borrowing from my build thread:

As mentioned by a few others, definitely start with getting the FRM coded to the vehicle and re-initialising the windows. The unusual reading on your scan tool may be coding related or the scan tool may be misinterpreting the data, so I wouldn't be too worried about that. Does the replacement FRM type match the original? (Should be on the casing of the FRM) @HELLBM can assist with coding if you want someone local.

As above, it's the RACP (rear-axle carrier panel) itself that has the issue, not the subframe. Take a read through this: https://cmpautoengineering.com/pages/part-1-will-my-e46-subframe-crack-how-will-i-know I'm personally running CMP's underfloor plates and topside beam kit on my E46 M3 Sedan build.

Consider just going for M54B30 + manual and set the rest aside for maintenance (how are the rear subframe bushes looking..? Cooling system, gaskets, etc.)
