Uprev, car won't start
 
I need some help, I went to upload my uprev tune and everything seemed to have went smoothly. I go to turn on the car and it won't start, it doesn't even try to crank. There is a small key light that appears right above the fuel gauge.

Can someone help me out?

Battery flat.?Key not detected.?

Lowbz21 10-13-2013 06:25 PM

The battery seems to be fine, same with the keyfob because I can put the car in the on position no problem. It is just I try to turn on the car and it says press the clutch even though I have it pressed, and the key light above the gas gauge is on.

That sounds like a bad clutch position switch.

That crossed my mind too but what's with the key light?

Clutch sensor has gone out

I dunno. :( If someone doesn't come up with an answer soon, try looking through the starting system section of the FSM (link in my sig). It has a description of what is supposed to happen, how to troubleshoot, and what any lights may mean.

Trips 10-13-2013 06:55 PM

Just a thought IF it is the switch? Try to disconnect it and jumper it with a small piece wire or paperclip?

If it starts theirs your problem just make sure it doesn't come in contact with any metal since it could be either a power or ground.

If it's a single wire only? It may just be a ground switch which then you'll just need to ground it and fire it up to see IF it'll start.

By all means use a test probe to detect if its using power or ground since all your doing is completing a circuit.

This is only a temp fix to bypass the Clutch switch IF thats what the issue is, and NOT the fob's Battery.

If you had the anti theft map loaded make sure you didn't accidently push the buttons to have the car on that map.

Thanks ill give that a shot, but the first thing I did was go buy a new battery since that was the easiest and fastest thing to do so I crossed the keys battery off the list.

Can anyone else chime in?

bacalhau1669 10-13-2013 10:10 PM

Have you tried the clutch switch yet? Plenty have mentioned that. Theres only a few things it could be and it certainly sounds like that.

I messed around with it before, I disconnected it and tried connecting a paper clip to the connector pins on the wire but that's didn't do anything. But to be honest I didn't really know what I was doing.

Also this is the key light in getting, as well as the clutch light.http://img.tapatalk.com/d/13/10/14/uzepyhy5.jpg

I highly recommend against doing things like that if you don't know what you are doing. It's very easy to fry one of the (expensive) control modules that way.

If you have tried all the other suggestions, I'd try flashing the ECM back to stock and see what happens.

Edit: IIRC, that key light means that the car is not recognizing the fob. Try putting it in the slot in the dash (near the VDC button).

I think I may have lost the stock tune while flashing to uprev, is there any way to recover it?

This was my first thought too.

Lowbz21 10-14-2013 10:02 AM

Question for you guys, I bought my cable used from another member that was selling his car, he put the license back on and everything. Also, since we have the same mods he sent me his tune file, are those not transferable to another car? He said it would work but the possibility crossed my mind. If you can't use it I have to figure out how to get the stock tune back.

windex 10-14-2013 10:39 AM

Did you flash the right file for your ecu? Or did you just use the ecu file that was sent to you?

Lowbz21 10-14-2013 10:40 AM

Just the one fine that I have which is the one he sent me, the program said everything was flashed correctly.

windex 10-14-2013 02:36 PM

Yea but did the part number match up with your ecu part number?

I see in the program it says "ecu part number" but where do I find the other part number to see if it matches?

roplusbee 10-14-2013 07:35 PM

Well you guys can rule out that the keyfob and intelligent key system as issues. Try disabling the anti-theft in Osiris or Cipher (not sure where it is), but it seems like you may have homeboy's algorithm instead of the one that goes with your keyfob. I bet it starts right up...............

Are there 2 different programs? Because I didn't see an option to do that in the one that I used to flash the car.

cdoxp800 10-14-2013 07:39 PM

Sounds like OP Flashed the Car with the Incorrect ROM.

Give UpRev A call

1. Read it off the ECU it's self.
2. Read it with Cipher
3. Read it with Osiris
4. Read it with Osiris ROM Editor
5. the Dealer can get you the ECU part number from your VIN number


Do you know the ROM file typically in the naming convention has the ECU Part number it meant to be used on.
Example:
1A32C base tune ( this I what I got from UpRev)

Now the ROM File you got ( Second Hand ) May have similar naming convention.
That being Said it MUST Match Your ECU's Part Number. You cannot take a ROM file from Car A and use in Car B.
ECU Part numbers vary year to year model to model.

Most likely Jared @ UpRev may ask that you send it in and they can fix it.

Thanks alot man I contacted the dealer and got the part number, got in touch with uprev and they helped me out and sent me a new file. Now I'm all good and the car starts right up, now I know what not to do. Thanks to everyone that helped me out I really appreciate it!

It still amazes me how many people modify their car and have no idea what they are doing.

Im very glad you got your car straightened out, but I hope this helps you and other newbs into reading about the car FIRST and then make changes. Seriously

First of all I'm not a newb at all, I'm just new to this car. My last car saved the stock tune as you change it with a very similar program so I figured it was the same.

Second, I read plenty about the car and didn't see anything about this. After all, this sort of thing is what the forums are for, one person has a problem, asks people for help to resolve it, and from then on people learn from other people's mistakes.
But thanks for the advice👍

bacalhau1669 10-15-2013 11:39 PM

Being new to "this car" would make you a newb in my mind. Great that you knew your last VW so well, but clearly this is different. Just because I learned buttloads about my last Wrx and the 40 cars before it, I am not an automatic expert when I step into a new vehicle I've never owned.

this forum IS great and has lots of useful information. Again, im very happy you didnt mess up your car, as using paper clips to jump relays on which you have no idea what they are doing, sounds like you came pretty close.

I'm just saying just because you're not an expert doesn't mean your a newb. I wouldn't say a mechanic is a newb just because he hasn't worked on this specific car before, especially because the basics are all the same.

Glad to hear this is resolved. Most "new" forum goers neglect to post that the problem was resolved and the fix action. This will help prevent others from making the same mistake.
