The M5 cluster retrofit

[geargrinder]

Yep I thought I remembered you were in Methuen or Haverhill or sunthin like that. Cool.

I'm off for the week to Mid-Atlantic but let me know if you have any car related meet ups and I'll do the same. When I'm not in Ando and not traveling I'm in Rockport where I have a garage so I do most of my car related stuff out here...

I have basically given up on this. I've gone in circles looking for the source that is feeding the current oil temp reading and what is causing it to read so high without an answer. The only things I've deducted is:
1.) being able to read german when reading the coding of the cluster is a major benefit and could help understand the 'offset' that is calcluated when reading the oil temp signal.. where ever that signal may be in the IKE coding
2.) the DME software needs to be modified to send the correct signal reading for the cluster to read accurate <- seems to be the taboo subject from what i've read here and other threads
3.) buying an M5 is easier.

First of all, this is a great post and a great DIY, and as others have said it's long overdue -- thanks for posting!

There are many pages of comments and suggestions, and opinions here. Some agree, other contradict and to honest my eyes start to cross around page 6. Clearly the hardest part of this process is getting the oil temp gauge and the dynamic RPM limit gauge to work with the non-M 540. Would some one please confirm if this was able to be resolved somehow other than trying to splice code from an X5 DME, or flash the unit(s) with other DME software and then flash back with saved 540 software? BMWPlanetDude?

I'd love to be able to finish the final step, but when you actually have to splice or edit individual lines of code that's slightly above my pay grade. Any help on this would be appreciated.

I've been meaning to post these pics for some time and ask around here to see if anyone know whats up with them.
So I have installed a 4.6 e53 X5 European cluster in my 2003 540i (automatic) ///M Sport.
For some time if been wondering if its actually working properly.

When it was very cold back in May, the cluster had nearly all the tach lights on and the oil temp gauge was reading low:



As the car warmed up the tach lights went out and the temp went up:



Then the other day I decided to check to OBD II to try and see why my car alarm keeps going off and found this:



I was thinking that, maybe since my cluster is from a European version,
the temp is showing differently because of it giving the info in Celsius and the car is trying to read it in Fahrenheit.

Anyone have any thoughts or suggestions?

So you installed the x5 cluster and didnt make any changes to dme? The dme for 540i from 2003 has similar programming as the x5 but does not send the correct readings to the cluster.

All clusters read in Celsius from the hidden obc functions. So its not a matter of converting to fahrenheit.

Your cluster doesnt look like its euro. Speedo would have kmh and no mph.

The cluster was installed and programmed by GSXRliterbikz. I was informed by him about the incorrect readings also. I bought it on eBay from a seller in Lithuania, under the MPH it says "UK", and it doesn't say "unleaded gasoline only" in the gas gauge. And the oil temp are only "50,100, and 150" when it's usually has "120, 210, 300" like the m5. All this led me to believe that it is a European cluster. image-726069511.jpg

ok, I was looking at it on my phone and it looked the same as I had, but you're right. There is also this version.

29f6lvs.jpg that only has km/h. Didn't realize there was a "UK" version too.

When I first read the post it sounded like you flashed the 4.6 dme euro version, but then I reread and understood what you were saying. Sorry if the question came off the wrong way.

Its all good dude. We are all here to learn and grow.
In any case, I posted the pics to get a response.
Check out the pic of the M5 cluster and compare it to my 4.6,
you can see the difference in the oil temp.

E39 M5 Cluster are kinda hard to find around here, does anyone know if E53 4.8is Clusters would work as well ?

4.6 X5 should work. Someone posted they had issues with 4.8 cluster not working though.

The 4.8 doesn't use the 7.2 dme does it?

[age109]

No. Here's what I found.

The N62TU engine is equipped with DME ME9.2.2. The functions of the ME 9.2.2 are
carried over from the previous ME 9.2 of the N62 engine.

From what I remember, the guy had issues just coding it to his car and it ended up on eBay.

I found the post I saw, but now it seems like he may just not have had the right software or wasn't using it correctly.

The part # of the 4.8 cluster was 62 11-6 942 222

I do have a 2001 530i, and have access to most BMW Tools SSS, NCS, Scanner 1.4. Would it be possible for me to do it ? Seems like everyone has only tried to fit it on 540is.

[geargrinder]

The N62 is way different than the M62 ME7.2. MAYBE you can cross code the cluster to work with enough hand coding of various parameters, but its not gonna be too straightforward I bet.

You might be one of the lucky ones. I think the dme (Siemens MS43) in 530i sends oil temp too with one of the latest stock flashes.

Its possible with 530i
See here http://www.netmgr.co.uk/bmw-e39-m5-cluster

Im not exactly sure how this guy got everything working but it all works

--Update--

From the comments here it looks like same deal. Everything but oil temp will work.

I got in touch with the guy who made this mod on his 530i,

he was kind enough to answer me at least, unfortunately its not that simple:

"Hi
Its not possible to simply 'code' the cluster to work on a 530i, the led countdown information is not broadcast over the CAN bus ever from a ms43 (530i) ecu and it cant be made to do so.

It only works on mine because I plugged in a custom designed circuit to send the signals it requires, this requires making direct connection to the circuit board inside the cluster.

Regards"

It's not so hard to make an emulator with required broadcast data.

Please provide a DIY. Thanks

Sorry, it's not our goal to make 3rd party modules for old cars like e39. But it's definitely possible with few dollars. Just curious where are these enthusiasts...

[AquilaBMW]

Here is my question. I had an M5 Cluster that was installed in an Automatic M-Sport. I now need to use it back in an M5 and I need to remove the PRD123 gear indicator thing from the cluster. Can this be done with either DIS or NCSExpert?

[FredRC]

Not to tell you how to run your business, but if it is that easy to make and with the amount e39 owners wanting to do this mod, I can only imagine how much money you could make by putting a plug n play kit for it.

Anyway, thank you for your valuable input.

You can get the E39 M5 oil gauge and LED warm up lights to work in a non-M5 E39 by using an Arduino UNO and CAN-BUS shield to send the oil temp data to the M5 cluster.

You will need an Arduino UNO
https://www.sparkfun.com/products/11021

CAN-BUS shield such as this one.
https://www.sparkfun.com/products/10039

The code and all the info to get you started can be found in the thread below. (post 564 and 565 specifically address the OIL warmup LED lights)

cool.

[6speedE38]

Does anyone know if a black faced M5 cluster with the "93s66 sw13" can be either recoded or replaced with a new chip. I know it is possible with the m35080 chips. I have googled to the end of google without any good results. I can't even right the VIN using PA Soft so I also have a tamper dot.

[Templeglantine]

Is there anybody in the NYC area that provides the flash that makes the tach LED's & oil temp gage function. I have the M5 cluster already coded to my car ('01 740i sport),but would love to have everything working.
