Hi,

I have the chance of a cheap 99 Felicia, but the guy reckons the ecu is dead. He has apparently had this diagnosed by some expert.

Anyway, I have seen the car and its worth having as its in generally good condition, but obviously not running. I believe that if I change the ECU, as it has a built in immobiliser, I also have to change the transponder chip in the key and the receiver around the ignition barrell, and the box of tricks the receiver plugs into all for a matching set from the same donor car? Is this true?

If I cant find a complete donor for these parts, is it possible to get the transponder stuff re-coded to the replacement ECU?

How much are these parts likely to go for 2nd hand?

How much would a re-programming cost? would this have to be done at a Skoda dealership or will any auto electrician be able to do this?

Anything else I should know about for this sort of thing?

I dont even know what size engine it has, it looks like a small unit, possibly a 1.3ish I can get more details over the weekendif needed.

Thanks,

Dave.

As you say the immobiliser is in a separate box. All that you need to do is get the learned values erased in the replacement ECU via VAG COM or the dealer tool, and the car should work with all its' other existing bits.

You can call Gary at Skospres on 01202-722-666, the ECU will have a part number on it ensure that your replacement is the same part number.

ECUs don't often die for no reason, I have seen one go because the battery overcharged and the acid contaminated it.

if you let me know of the part number i have one that may fit for

Yeah the alternator over charges and the CU doesnt like 19vs up it so pops the main fuse but not before overloading the ECU. I'd check the fuse first, however you will probably find the ECU now has a dead short.

my ecu died not that long ago, check the thread 'selling a 1.3 mpi' but basically if the ecu is dead then the only thing you will have to do is have the keys coded this cost me

Yep, common problem this - my old Favorit fryed its ECU when the voltage regulator gave up the ghost.

Plenty of em about though, don't pay more than about
