Got the code a couple of weeks ago and my dealer cleared it with no other problems noted.

On the way to Denver the check engine light cam on again. We also had an issue when the wife was driving that the gas gauge went to zero and the low fuel warning came on, about 5 minutes of this and it went back to full...no ther problem at the time.

Got to the hotel and borrowed a Dashhawk to reset the code.

Went on the Peak-to-Peak run and had no turbo response. The check engine light came on and was reset for the third time.

After dinner at the Lodge Casino we had no turbo response and the light set for the fourth time, which we reset.

Took it to the Saturn North dealer on Saturday morning and they ran diagnostics. They saw the same code and said there is a bulletin about cracks in the turbo...wanted the car for a 3-day tear down and rebuild\replace the turbo. Told them "No thanks" and that I would have my dealer do what needs to be done when we get home.

Looks like the code is a symptom of turbo problem, so I will update with what my dealer finds. Will try to have pictures if they find something in the turbo.

To bad they didn't see in the bulletin the words that say:

GM TSB said:
These cracks are not uncommon and are considered a normal condition and should NOT be a reason for replacing the turbocharger assembly. The cracks will not affect performance. If the vehicle exhibits driveability concerns or turbocharger DTCs P0299 or P0234 are set, refer to SI and follow the established diagnostics for correction of the customer concern.

Thanks Shabby. I went and looked, it was worse than a loose nut, the nut was missing.

Went and talked to Dave at DDM, he said he [robably had a spare nut that would fit. He did. Dave put the nut on with second lock nut for me in the middle of his other install work. Took it out for a test and still got a code, but had boost to 19PSI.

Another Solstice enthusiast adjusted the nuts back closer to factory and I got no code on a short test run with 18PSI.

I just love having friends that can fix things that the dealers don't see, even when it should be obvious. Thanks guys.

Trip home yesterday from Colorado had no codes or check engine lights...had lots of power. Amazing what the loss of one nut will do to the car.

Reminds me of a poem my Mom used to recite about the war being lost because of a nail...

Is THAT all I am? Just an "enthusiast"?

LOL ;)


Yes, it is bad when you lost one of your nuts, and you run around with just one nut, wondering where your boost went.

Wow, that sounds highly suggestive, somehow.

Code P0299 is a turbo underboost code. It makes sense seeing where your nut was adjusted to. I checked it in the service information this morning.

better to be an enthusiast than a naysayer.

Also better to be a wrench picker upper than a tool handler :)

If I had a piece of cardboard you wouldn't have had to pick up a wrench. :willy:

I wasn't going to "out" my secret mechanic so that I could take advantage...I mean ask for his help again in the future. :devil:
