Hello everyone.
I have a Audi a3 1.8t agu engine
The cars been stood for 3 days I jumped in it yesterday and started then splutterd and cut out. I pumped the peddle and same again it splitterd and cut out.
Now when I try it it
dosent attempt to start just turns over.
I can't hear the fuel pump priming. But if I put a 12+ to the pump it sounds like it's working.
I changed the relay 409? under the steering wheel still no joy.
When I first tried starting it there was a wining noise coming from under dash so I thought it was the relay.
pulled spark plug out and it didn't seem like it was sparking.

Iv had it plugged in and it dosent bring up any codes for crank sensor or cam sensor or anything I would expect for it to not start at all.

If got the print out of codes if this helps anyone come to a solution to this problem.

Checked fused on top of Battery and in the fuse box on drivers side dash, all are fine.

Been messing about with it all day and no joy at all. So if anyone could help pleaseI'd really appreciate any input you guys have.
 
Ok so fault codes are.

Charged battery over night. Put it on then jumped in car ignition on, fuel pump primed (one of the relays was going crazy buzzing and whining) car started fine then splutterd and cut out and failed to start sinse.
 
Update: charged the battery all night then put it on jumped in car and the fuel pump primed (while turning the key to ignition one of the relays under dash was going crazy whining and buzzing ) and then turned the car over it started then splutterd and cut out. Failed to start since.
 
Just done some more investigating. The the foam carpeting stuff around the ecu is soaking wet.so maby it's down to that? :S

If I was to remove ecu to attempt to dry it out. If I plugged it back in would it need recoding or anything or should it just work fine plug and play?
 
audi upgrades
Okay so I did this today removed ecu opend it up and it does have some water damage cleaned what I could being careful not to break anything... Put it back on car. Fuel pump primes car starts then cuts out. Immobiliser light flashing.
Anyone know how it reset imobiliser?
 
Yes its not so hard. Dont know if there is anything on this forum but im shore its on nefmoto. You can try googl as well.
 
I did try looking up some stuff but nothing came up that's related all to do with swapping to a diffrent ecu all together if anyone can link me to something I'd appreciate it. I can get a vag.com machine later if this is how I do it? Some institutions would be useful :p
 
audi upgrades
Quite sure he is on a 3.8 so dont think this would apply to his ECU.
 
Sounds like your immobiliser key fob may need to be programmed, audi and some key cutting places should be able to do this, I doubt it will be cheap though.
 
do Audi really start a car then switch it off with an immoboliser, pretty sure every immoboliser error I have ever had on kai, fiat and BMW only turn a car over - it never seems to fire and then die?
 
Sorry guys only just seen the posts that's some good info thanks. Why would the ecu forget the key after taking it off and putting it back on? The key fobs still work so that made me assume the key was still programmed to ecu? Does anyone know where I can get a De-imobilised ecu wich is remapped also? Thought while swapping ecus I may as well get a remapped one an eBay seller dark-tech does them but has non for my ecu code.
 
The thing with that is if my ecu has forgotten the key or cluster for no reason then could it have fried something in there. The Circuit bord doesn't look good. So thats why I was thinking of a new one all together. I dident want to send the ecu off for them to say it was fried anyway
 
Try looking around rosstech's website, for instructions on pairing the cluster and ecu. It's possible your ecu lost the pairing when something got shorted by water...
