Car won't start...ECU?

[skcollob_ho]

But would the crank sensor produce the same symptom as the imobiliser, where the engine turns ans starts on full throttle, but dies within a couple of seconds?

quite possibly, the one i have on atm has some bare wires+ when i drive in the wet it dies, then wil start for a few secs with full throttle+ then die again until it dries out

yes, if it is a stock imobilser that is causing the problem then it is built into the ECU. Check first and make sure you dont have an aftermarket ECU.

I believe the imobiliser in the ECU can be bypassed, but i carnt remember how and it requires special software.

Have you checked the igniton switch. I carnt remember the wiring for it, but it 'probably' has a wire that feeds the immobilser.

The revision number on the end of the part number is a revision number and shouldnt cause a problem. If you want to double check look up the part number and revision and double check, but in the past i have had ECUs where the revision is alot newer and now problems. If you change the ECU, its probable that it will need coding to your keys. £60 at VW main dealers or find some kind person that has the right software to do it

After a bit more digging, and for the benefit of anyone that finds this thread through searching, I have found the following.


ECU P/N: 037 906 024 ** [where you will find the following letters]

The following are imobilised;

AE, AL, BE, BF.

Without imobiliser are;

F, G, AB.

This is probably a stupid question, but I may have located an ECU out of a Seat Toledo that carries the AB revision. Will i be able to transplant this into my valver without issue? If I'm getting it right, then the AB revision doesn't have an imobiliser, thus no transponder, thus no need for the key to be re-programmed?

ecu for ABF part no 037 997 024 GX  other revisions G, X, AE, DX, BE,

Same part no but BX/SX is the 2E(old 8v) ecu so i doubt they are compatible

lol, should be fine outta seat, where did you get the info about immo or not??

i believe the immob is located in the clocks, not in the ECU itself.

i think you're talking about the transponder thats located behind the clocks.

no the transponder itself is in the key, the immob is part of the clocks.
