battery went flat,couple of days till i got it changed,now the bucking thing wont start for love nor money just cranks over and not a kick
had a man out and he reckons that the becm isnt sending the code to the immobiliser

W T F DO I DO KNOW ?!

SORRY !..NOW..!

first thing is to tell us your location then someone close with a clue (and a compatible bit of computer wizerdry) can come n help you

im in tandragee in co armagh,norn iron.

your gonna stwuggle out there!!!

pm irish rover he's defected to that island somewhere, dunno where tho. think they get thier fuel from a bloke called pete where he lives

they only have electric between 5 and 6 so it may be a while till he answers and it'll be in burmingish so you may need a translator but he should know someone!

Bastid..... Briggsy :mooning::mooning:

We have electric for the whole day, first Monday in each month so todays your lucky day !!

I have the full P38 diagnostics but am based in Edenderry, Co. Offaly, about 35 miles due west of Dublin.
PM me if you wish.

:behindsofa:

i dont need to pm u, mines working!!!

and for you info, my mum and dad were married!!!!!!











just not to each other!!!!:mooning::mooning::mooning::mooning:

say it worst case scenario and it is becm are those sync mates worth a toot or are they 100 notes worth of sheeite ?

They are a good piece of kit, especially if you live a fair trek to someone with diagnostics. BBSguy is giving a discount to members of the forum.
If the BECM however, is in Alarmed status the synchmate would not work.
The concesus from guys on here that have bought them is that they work and have paid for themselves.

Why Thank You IrishRover
Hope you don't mind me butting in
100 notes worth of sheeite indeed ITSMYDAS
I have half a mind not to sell you one now
mind you the other half of my mind is thinking about things like the mortgage and keeping SWMBO in shopping tokens
Well she does buy my beer with them

It's a bit of a mystery as to why the BeCM changes its stored mobilization code to some random number that the EMS does not agree with causing it not to start. Some say it's radio waves caused by parking to close to a transmitter, and one guy firmly believes its because his mother in law is a witch as it only happens when he leaves his P38 outside her house for a spell. I kid you not
Frankly however, i support the theory that it is down to cranking with a low battery voltage, which your experience does seem to bear out.

In any event, no matter what the cause, i can promise you that when you plug in one of our sync mates, it will access the engine management and read the true immobilizer code, then it will access the BeCM and store that code in it, all in the blink of an eye, so that the next time you try and start the car the BeCM will send the right code. Unless of course it's a Golf, in which case anything might happen

As IrishRover notes, we are giving a 10% discount to all established landyzone members, all you gotta do to get it is Buy on line in the usual way and then PM me your order ref number.

PS, not only is it an option for those living too remotely from anyone with a full on sort you out system, but apparantly it also seems to work equally as well in close proximity to witches.

do they work on all p38's or are they specific to post 99's

Hiya gavbriggs

There is a complete reversal of how immobilization things are handled BeCM to EMS ECU end between the Lucas / Sagem GEMS (pre 99 Petrol) and the Bosch (post 99 Petrol Motronic 5,2,1 and all EDC diesel) variants of the P38.

In both cases the BeCM has, a numerical immobilization code stored a common location that gets transmitted to the EMS ECU whenever a valid key fob press or valid EKA code entry is detected.

In the case of GEMS, this code can be anything you like, chosen entirely at random. This is because the GEMS can be instructed to "Learn any code" EG if you type in 123 in the BeCM's immobilzation code box, the engine will not start. That is until you issue a command to the GEMS to make it learn the code being sent. It will then learn 123 as its immobilization code and will thereafter start whenever the 123 code is sent. If however you then set the code to 124, the engine will not start.
Unless of course you tell the GEMS to learn 124.
So in the case of GEMS the code itself is totally flexible and you can get multiple GEMS ECU's to learn the same code.

With Bosch however, in both Post 99 petrol Motronic or any Diesel EDC, the situation is reversed. When the EMS ECU is manufactured it is given a random number that is impossible to change. It is possible to read these numbers, but i promise you that ain't easy and requires negotiation of a few anti access measures and is never revealed in dealer level equipment, but nevertheless, once obtained. you may as well write it on the side of the ECU with a permanent marker pen.
In order to start, the EMS ECU must have that exact code sent to it from the BeCM, and so that code must be stored in the immobilization code location.

Although a change to a random number in the BeCM's stored code, which is what appears to happen, would theoretically stop either type system from working, our experience has shown that it primarily seems to happen only the Bosch type vehicles for some reason, and as such we have created Sync mates to fix this for the 99 on Motronic and all years Diesel EDC vehicles. we do however have a weather eye out on the GEMS and if required we will introduce a version for that too.

I hope this helps without getting too technical

warmest Regards

Colin
