Had my car in for a tune today, unfortunately it couldn't be done as it looks like it has previously been mapped but been flashed back to standard however there is a code still on at the ECU that the tuner couldn't get by, it looks as if the previous tuners may of done this. I've been advised to get the latest BMW software update installed, apparently this will wipe what's on it for the BMW update to go on then after I have this done I will be able to get it tuned as this will be a base platform for the tuner to work off. I took it to a reputable tuner and he's never seen this code on it before to bypass..

Has anyone had similar experiences?
Has anyone had to get the latest BMW ECU software installed and if so what costs?

Thanks

Sadly not unheard of you can get various faults with in the ECU from say 2D5A which is an engine torque limiting code along with 2D59 DME internal fault monitoring code, this one measures the actual torque (both codes are signs that the maps torque parameters have been altered) to various other codes re communication such as non communication codes of which there are from memory several. Another codes or faulty hat can come up is 5E19 which is an engine management interface registered code. The issue usually as you may have been told is down to a and I'll use the term loosely a 'rouge map' we see a few oddly enough from one well known company I can think of at least 3.

There are other internal DDE codes that do come up as well the above are the ones I can remember thst do crop up on the MSS80 unit, the only option is to get the car back to OEM, either with an Indy with AutoLogic for example or if your very lucky an Indy like us who's got the genuine BMW set up which is damn rare as no one wants to pay the various charges that are laid down by BMW, but boy is it good, better then AutoLogic but AutoLogic will do.

Once your software is updated re set all adaptations to be 100% OK, then the cars driven, we usually go for a day to 2 days running standard software then re scan post this to verify that the cars adapted to the software and the glitch is no longer present(once the software not re flash is done you'll be able to see the corrupted area gone)

Once everyone's happy that the issues gone then re maps back on the cards

When I bought my car it had an Evolve remap which I wanted to bin off. I took it to Jason at BWChiptune to just reset the software with the latest to remove and get me back to a base.

As Steve has stated an Indy with the autologic can do it.

Then just added the JB4 (which is highly recommend).

Appreciate the replys.. Can you tell me what's the cost to get back to OEM..

Thanks for the info, where are you based about?

A long way from bonny Scotland I'm afraid. If you're struggling to get the situation sorted you might have to resort to main dealer intervention so that they can upload the latest software, but if you can find an Indy that operates with AutoLogic I think you'll be fine.

I'm able to update whole car to latest firmware, so may do it for you depends where are you based.

Find a better tuner...

Ecotune in Glasgow maybe?

I've flashed my brothers 320d before, but i wouldnt want to do a strangers car incase it fecked up.

This was the tuner I took it too.. After a lot of phone calls today I've found B&M Glasgow who can flash my ecu back to OEM, have you heard anything about B&M? I will be going back to Ecotune once I sort this issue out. Cheers

Frankly i'm amazed that someone who claims to specialise in BMW's doesnt have the ability to flash the factory BMW software back on.

I certainly wouldnt be letting them map my car if thats the case.

I think the problem being the previous map has been coded so it can only be be altered by that coder.. Kinda like a firewall I suppose. I'm guessing if I took it to any other tuner they too would have the same problem.. Who knows. Just want it sorted and then gain some more ponies.

[Aragorn30d]

My point is the BMW software is freely downloadable online. If i can manage to buy a lead, download the Datens pack, and flash my brothers 320d with the latest BMW software, then i'd expect no less from anyone claiming to specialise in BMW tuning.

A guy with a cheap cable, BMW Standard Tools and a knowledge of how modules work can resolve this problem.

Just on a side note...I would take this opportunity to create a cloned ECU. There is a guide on this forum somewhere. The idea being that you have a cloned DME / DDE which is synced to you car with a different map so that should anything go wrong you could simply switch back to your stock ECU. Given your location you could also send your remap ECU off for new maps / updates rather than travelling miles with the vehicle...

Sounds sensible!

[walkerE90]

Hey guys.
Update if your intrested.. The DME has been updated with latest BMW software and coded. Problem still persisting where the seed code(obd password) is not stock, coder can write a software no problem but cannot read as this is blocked through the seed key (obd password). They have most read/write tools and they tool manufacturers came back with the same verdict.. I'm not sure any other way around it unless they forced the ecu or changing out the module which is a hell of a expense for a extra few ponys! I'm also wondering if the famous JB4 could over come this??!

[Aragorn30d]

Find another tuner.

[walkerE90]

Having no luck at all with this.. I've had car put back to BMW standard twice now via DME, tried another tuner and they have same issue as the first tuner, unable to read software but the can read codes and identification number etc and obviously we're able to update DME with up to date software. I've been told only option would be to replace module which is just way to much of a expense for the sake of say 50/60bhp through a flash tune.

Would the JB4 overcome this seeing it's a piggyback and not a flash tune therefore does not require to seed code (obd password) restrictions with what I'm experiencing..

Getting a headache with it now !!

[zltm089]

why did you waste money on those "tuners" who can't even put a car back to stock?

I would have taken ti to BMW and get them to "get the car on a stock map".... and then.....get a jb4 or a cobb.

[zltm089]

ohh re read the posts now......i wouldn't trust those tuners at all!.... how do you know they have put the bmw stock map on?...
