Hi all,
Well as it says,I bricked it.

I'm not to upset about it really.What I mean is that Iv'e done a few flashes to my ecu now and never had a problem.
I started with a cat & rear O2 delete,then a SAI delete,then a new LAMFA with SAI delete.All great.

Spured on with enthusiasm and now having my fuel curve where I wanted it I modified LDRXN and loaded it back up.Car started rite up and I went out to log a WOT pull.
On the way to the road I do my pulls on a few squirts of the loud pedal showed great promise and all felt great.Then on the last sqeeze of the throttle boost starts surging and multiple miss fire's continuously, feeling like it's only on three cylinders.Engine malfunction lamp flashing about once a second.

Sopped the car,cleared the fault codes.Still no change.
So I remembered that I had zeroed CDKAT and thought well I'll just put it back to 1 and load it up again and see what happens.
Bricked..!!!!!!   And that was it.Cant connect to it at all now with anything and the traction control light is on permanently.
Well I've allready got my hands on a replacement 06A906032DR ecu along with the cluster,two keys and the transponder.

Thing is I really want to know why it happened.
I did it all rite,Check summed it first,connected it to a battery charger,etc,etc and never had a problem before.

Any thoughts guy's ?
All the very best
O.T.

Hi gsfesz,
I tried that one.Soldered the wire in and went rite trough the whole procedure to the letter of the instructions but I can't get it into boot mode at all.No matter what I tried I could not find a way to communicate with it.Terrible...

I really thought I would be able to boot mode it to.In fact,there was a small bit of me was quite pleased to get the chance to try boot mode out.
Perhaps I damaged it in some way.
It would be good to know though so I can try to avoid it in future.

All the best
O.T.
 

Do not do any soldering for boot mode.

There is very little that can go wrong to prevent bootmode, no matter what the flash content, short of physical damage to the ECU itself.

Sounds like they're lying to you.

If you bricked it, pull the dash fuse if trying to boot mode in car.

Also if using mpps and your having trouble use "slow" mode

Only once have I killed a me7.5 dicking about and it fried the chip, swapped from another flashed known good file etc all ok.

Maybe your boot mode method is bad?

Earth boot pin recommend the solder blob a little away from chip (follow trace from pin you'll see)

Ignition on, wait 5 seconds disconnect Earth on boot pin. Do not ID or Read ecu, Only click Write then use  known good file.

exactly what are you trying to do when putting it into boot mode? you should be grounding the boot pin on the eprom or solder pad for 8 seconds or so while powering up the ecu. youre grounding the pin on the processor so it boots in boot mode haha boot boot. anyway wonce you do this you should be good to write. ohhhhhhhh also make sure you right click and run as administrator. I think i can recall a issue like this because windows wasnt allowing it to have control over the com port? idk worth a shot
best luck.

p.s. might consider the chance of that ecu being shorted?   

Nope,tried it again just now and exactly the same thing.  "Boot mode is not initialized".

As a breakdown of where I'm at with it.
I've got the 47514789 into the cable and I've tried with two cables,but still No.
The harness and methodology,I've double and triple checked and I'm 100% satisfied that it's correct.

So,do the electronically minded of you out there think this could be a physical problem on the board?
I've really checked across the board on both sides thoroughly,but I cannot see any obvious signs of damage.
Are there any components or areas that could be damaged?,Are the electrolytic's on the board usually problem free?.(just thinking out load really)

I'm not adversed to a bit of fault finding and I've got a fairly decent scope here and a decent meter.Perhaps the more knowledgeable out there would have any thought's.

All the best
O.T.
