Default OBD code 16518 P0134

This code has popped up on my VAG reader as a faulty oxygen (lambda) sensor B1 S1 no
activity. This happened during a track day, I may have got a little carried away with myself
chasing others around the track. At track was able to change N75, MAF sensor, checked forge
007 DV (ok), checked for leaks without success. Car drives with little or no boost, as if its by passing somewhere. The following day changed O2 sensor (pre cat) thinking this would sort
everything out, but no. Code returns quickly. Having no visible signs of a blown turbo, i.e. no
white or blue smoke. Have tried pressuring the intake side, blanking off PCV, and using air line set at 10psi, through the TIP(tip removed), I can't seem to raise pressure, is it possible that my waste gate flap could be stuck open ? Will check this asap, some positive thoughts would be appreciated guys.

Regards Lenny

After replacing the O2 sensor did the code come back right away? If so the wiring to the O2 sensor may be bad. Check for cracks or corrosion.
Your car is probably in LIMP mode and not procuding any boost.
Reset the ECU and see if that gets your boost back.
Also check your Catylitic converter. It may be bad as well. Shake it and see if you hear any ratteling sounds. If so the ceramic in the Cat has broken up into smaller pieces and is blocking your exhaust path which leads to massive back pressure.
Also what spring are you using on your Forge DV? Don't use the Yellow. The Green is plenty for the little Turbo of the Beetle. The harder spring actually reduces power.

Also check your MAF sensor connections and make sure it's clean. What type of N75 are you running? I used the N75 Rave valve and didn't care for it on my Beetle with my REVO stage 1 tune. It actually reduced my boost instead of increased it.
Good luck in getting the car fixed.
Keep us posted!

It was the hose pipe which comes from top of the turbo to the metal charge pipe.
Large split, how I missed it, I don't know, but sorted now, thank goodness
