What have you done to your mk4 (golf/bora) today?

[geoff_gti]

Luckily, yes.

Depending on which Immobiliser you have:

Immobilizer II ECU Swapping - Ross-Tech Wiki

Should be this one

Thanks Gavin. I'm almost certain mine is Immo II. I'll probably have to wait until the weekend to install it now. See how I go... Can't wait...

Mine was immo 2 and needed no recoding etc

Mine was immo 2 and needed no recoding etc

so... it just plugged in & started up fine? No VAGCOM at all?

Erased learnt valies, scanned and cleared, and when my wiring wS sorted, she fired and ran

Good news, see how I go throwing it in on Sat morning then!! Can't wait!

Do I have to 'drive it around' etc for a while to get it to kick in? Or do the method of: 'warm it up, do the ECU swap, then hammer it, then cruise' to get it to sync? Anything like that? What's the best method there Gavin?

did that ecu originally come with that engine though, i think its a bit more involved if the ecu wasn't originally for the engine, u have to code the immobiliser

[kendog]

Yeah, that was my understanding. Anyway, Immo II looks pretty easy compared to Immo III, so I should be ok.

[Stan]

ecu came with the engine. The immobiliser is built into the dash instrumentation, original instruments in the car.
give it a go and see how you go i guess, all the best

Erased learnt values, scanned and cleared

This is coding.

Up to 2000/01 erase learnt values, ign off key out for 15 secs and next ign cycle they marry up. if not then its eeprom read for skc and marry the immob to the ecu, thats it really, bare in mind and have went over this a bit and seems all have been lucky to have VDO dashes, there is 3 types and a few types are the Motometer, that ok but be prepared to have a charger on the car fo r about 3 hrs for the second pass on the password, VDO 5 mins Moto 3 hrs no question. Looks like you either have early ones and no needing to code new keys, thats when the fun begins with the 3 hr pass.
good luck anyway

HELP! HELP!

Hey Jmac (or anyone else that can help)...

I followed the Ross tech instructions here: Immobilizer II ECU Swapping - Ross-Tech Wiki , which all seems fine, until I get to the bit that says "SAVE", and the vagcom program says it needs an activation code!! Help! Stuck in a mates driveway & can't move the car... Starts, but shuts off after a few seconds. Immo light flashing.

Is that Ross-Tech method I linked to what you described as 'erase learnt values'?
