Urrgh...
I'm generally happy with my car, she's got a lovely interior, but every now and again, the dreaded P0299 (low boost pressure) pops up and the car goes into limp home mode until I clear it. I've got an Android car stereo running "Carscanner" and a Bluetooth OBD2 scanner installed, but because it doesn't do VAGCOM, I can't get all the diagnostic codes, so I'm stuck with the generic P0299. At least I can clear the fault when it appears, but it's beginning to appear a lot, suggesting things are getting worse, or that something is reacting badly to the rain. It doesn't rain much around here, but the check engine light seems to come on far more frequently when it does than when it's dry. It also seems to come on mainly when cruising with the engine at about 2100 rpm. Which is annoying because cruising on the motorway at the speed limit in 6th gear corresponds to almost exactly 2100 RPM. Urgh.
I cleaned the EGR and inlet manifold last year, and yesterday I finally got around to changing the boost pressure sensor. But when I took it onto the motorway, and guess what? Yep...
I know people have spent loads of money on guessing how to fix this, but I don't have loads of money to throw at the problem. Either I find the issue and fix that, or I sell the car and go find something with fewer problems.
I'm mulling over getting a proper VAG-COM application, such as VCDS, OBDEleven or perhaps Carly. OBDEleven seems to have as many diagnostic capabilities as VCDS, it's a hell of a lot cheaper, and there's an Android interface, meaning I can run it on my car stereo and grab a freeze frame if the engine pops while I'm out and about. Is there a significant difference between the two? I don't really want to get rid of my car, I'd rather identify and fix the problem.
