swapping tdi ecu's advice

[cordobabrendy]

Im trying to swap a revod ecu for a standard ecu and have ran the adaption reset via vagcom, the immob is still flashing and remote cen locking still doesnt work, are diesels different as far as this is concerned over petrols.?

 

[cordobabrendy]

any tdi people out there?

I thought you had to get the immob reset by the dealer?

I thought that the idea was to stop someone just swapping the ecu and driving away?

I believe when the dealer gets the reset code they dont even know what it is!

I maybe wrong though

i think you need immobiliser defeat by custom code , possibly revo can do this too -unsure, tried it today with my car and grants (grq) and it definately wasnt happening followed the procedure as u would a mk3 ibiza , on both blocks 17 and 25 and still no result, something to do with immobiliser3 i think , (mk3 immob2)

Have you looked to see if there's any procedures for this on the Rosstech (vag-com) site ?

found it earlier lee

tho you need to get to a dealer and see your seven digit code and the date that code was created

muddy yea there is all the details for immob 2,3 and 4 there we didnt have the skc's though and wanted to know of any workaround, ill tell the fellas to get theirs of the dealer.

there's also a so called "immo bypass" file going around the net [p2p],,, I got it if you need but I don't know if it works, never tested it,,,

cheers carlo but to be honest, neither car is mine so wouldnt want to be doing something that could backfire.

Stoney, you say I can get the code from my Dealer along with the date......
Will they ask me some awkward questions though if I do that? Can I phone them for this code or would I have to go in person do ya think?

I heard that on MK4s, they "etch" the cars VIN details into the programming so it will not be accepted on another car. Money for the dealer if it blows up!

It could be this, I could be misinformed though!

You have to go in with your driving licence and V5 for things like that!

i could Clone the serial eeprom from the working ecu and flash it on to the spare,, then the spare will start the car.

Was a shame it didn't work, was hoping it would

Still at least the cars started after replacing the original ecu's, otherwise I wouldn't have been a happy bunny

me and steven were cacking ourselves

 

[cordobabrendy]

haha you should have been sat in my y-fronts too, id reset adaption etc and was only 99.9% sure it would wtill fire up ok, that 0.01% is a cnut!

our percentages were reversed
