Default Problem with TXS Tuna, Help

Yesterday my TXS tuna starting going crazy.

The car is idling and the AFR is approx 14.5 then it goes out of range.

The im driving and the AFR is out of range there are no numbers on the screen.

It periodly comes back on and off but for the most part it is out of range.

Anyone had this problem or know what it might be, the fuel setting are unchanged and it does not feel as though the car is really leaning out.

Any help would be appreciated.

Thank-you.

How many miles have you had the O2 sensor in for?

Might be time for a new one.

New O2. Hope you got the VW sensor. I keep a spare in the car in case the dealership has run out.

Anyone know of a good source for VW sensors at a good price? I've just figured out that I can use a company line to get the sensors at a better price (than $60 ish). But that's probably still not a good deal.

And a warning. I have had one be bad out of the box. That made for a confusing troubleshoot. It acted just like the old one.

If you got the VW O2 sensor with it then you can get it from a VW dealer. Thus my earlier reference to "the dealership". Look for the parking lot full of hippies and overpriced german tin cars with flower holders in them. It's a dead giveaway. (no offense Hippy )

The part is an O2 sensor for an '02 Turbo beetle. I think it's the front O2 sensor, but look at your plug. It's a "D' shaped plug and the other '02 turbo beetle O2 sensor (the rear sensor AFAIK) looks significantly different.

If you got the 'nicer' (more expensive but faster reacting) bosch sensor setup, I'm sure you can find an alternative source for the sensor besides TXS, but I don't know where.

Yes they wear out. It's part of the game. You aren't driving a stock car anymore. The 'stupid' Tuner is still fine. You want everything to last forever, get a honda, and don't drive it hard or modify it.

Oh... before buying anything, have you tried a free-air calibration lately? Pull out the manual and check that out.

yeah do that... and if your tuner is accessible, swap the main unit with a buddies you know is working and see if it does the same thing.

if you have a stick shift you can free air calibrate it without having to pull it out of the exhaust. i started a thread on doing just that on this board.
