After getting my Fabia home it went into limp mode (no more than 3000 revs) and wouldn't actually get off my drive. I was advised to take the battery off for 15 minutes and refit to clear the fault causing the limp mode. After refitting it wouldn't even turn over, I then had it connected to a vagcom which came up with faults along the lines of the ECU is dead. I'll have to check again to get the codes for you all. I've been told the only thing I can do is get a new ECU, I'm unsure as to what else needs replacing or is it easier to just get a new ECU coded.. I have no idea.. Thanks in advance!

More Likley you've blew a fuse or damaged / incorrectly fitted the battery.

I'm not sure it will help but I have a spare ECU from a 1.4 16v (100bhp) engine here.

where abouts in cumbria are you?

 

has your battery got voltage in it will the engine turn over if not i suspect the voltage has dropped too low and the ecu has shutdown into limp mode

Depends if it's from an AUB or BBY engined car.

I've got one too, ill check the engine code and get back to this

The car has long gone, but it was a W reg one, so fairly early?

 

A search would lead me to believe this is from AUB therefore as looks like BBZ came in 2003+ ?

W reg would be AUB so suitable, however I suspect the real culprit is the battery/alternator or a fuse.

I agree. It could also be the good old broken load sensing wire.

So where do I start then? New battery and go from there?

Check the fuses and fuse link strips on top of the battery. Look carefully at the fuse link strips as they can have hairline cracks which are not easy to see....

Look underneath and check that the alternator load sensing wires haven't snapped....

 

 

Check connection is clean and the nut is tight on negative lead from battery terminal to car body....

 

 

Charge the battery and start the car and check the alternator voltage output. If OK, suspect the battery.

Cheers for the help I'll have a look tomorrow and I'll let you know how I get on!

Turns out it was the earth! As soon as I'd cleaned it up it was back to normal thanks for the advice job done so glad it wasn't as bad as I was told it was! Thanks for the help!
