P0299 - 002 - Control Range Not Reached

[mtroxel]

I've had no boost codes ever, as soon as I do an APR Stage 1 yesterday, I've had this code 4 times now.

Done quite a bit of reading. Did an N75 output test in VCDS group 03. Cycled on and off for a minute without failure. Did a piston type DV a month ago, so I assume that's happy.

So, ran a WOT log in 3rd gear. Is this a boost leak?

Sure looks like it. Log n75 duty cycle along with boost pressure. Or do a boost leak test.

I'll look for it in VCDS tomorrow. What's the spike in actual at the end after the specified has dropped?

[p0isin]

Possibly two data points with the same RPM values from the vcds log getting double counted on the graph?

Good thought. Doesn't show on the raw data, but it makes sense when the actual PSI go from 8.845>14.935>6.38. I could believe two data points in the 7.5 range might be put together.

Yep. Same thing here. Under stock, the delta between request and actual isn't enough to trip the MIL, but under extra boost request with APR stage 1, it is. APR guy told me that it takes 150 (some unit of measurement I'd never heard of) variance to trip the code in the ECU.

I've got a DV+ sitting in my garage that I'm going to put on before I start chasing a leak or trying to test my N75. It's not really bothering me right now. I'm still getting more boost than I was stock.

[mtroxel]

Would like to know how your DV+ goes. I know the piston DV I just put in leaks a bit by design.

I too know I'm getting more boost than stock. I can feel it, and see it on that graph. I'm going to stop by the shop that did my APR and see what they say. They've done a lot of these. I'll post back here if he's got any light to shed on it.

Keep us posted. It'll probably be next weekend before I get to attempt the DV+ install. I hear it's a royal pain to get the DV out/in. Mine is the newer piston one, but I had my mechanic friend put it in on his lift. It's been in there for probably 40-50k miles and I've heard they can be leaky and slow to respond in general so I'm looking forward to the DV+. I've heard nothing but good things about it.

So I stopped by the APR dealer that did my flash, showed him my logs. He said, "If you've never seen this code till you did the Stage 1, then I would guess your 115,000 mile turbo is just sloppy enough that it can't keep up."

Said he just changes out the core of the turbo....doesn't include the ex manifold or the casting on the other side, it's just the middle of the turbo with bearings, vanes, etc. Mentioned some brand, don't remember what it was.

Besides your underboost issue, that spike itself isn't good your over boosting when your DV should be relieving pressure. You sure you plugged it back in?

Had to go out and look. Can't see it from above but I did it a month ago. I'd get a code if it wasn't plugged in wouldn't I?

I'm in much better shape now....I think. My air filter had 25,000 miles on it. I haven't had a CEL since the new air filter, but I still get the P0299 in VCDS, but not as often. Here's my latest 3rd gear WOT. Actual is closer to specified, still with the little spike at the end though. How close should the specified and actual be?

Been over a week now. I've had no CEL since a new air filter, but have seen a "pending VCDS P0229" twice now. I'm going to say the clean air filter made a big difference, but my turbo probably needs to be swapped sometime in the near future. I'm not in a big hurry to put $1,000> into it so I'll wait till I start seeing more P0229 CEL's.

[Sanjman]

P0229 or p0299? Two,different codes

You caught my dyslexia. Still have the problem as you can see by my boost test thread.
