850 T5-R Auto high rpm power?

[hausmeister]

Using the codes description on this site I found the following:

Trans
A1 1-1-1

Fuel
A2 1-1-1

ABS
A3 3-1-1 can't find this one.

Combined Instrument
A7 1-2-2 122 Temp. sensor interval too long

A4-6 don't have contacts on mine.
Not sure what to make of it, engine and transmission are ok? (1-1-1)

Any advice?
Edit: went for a test drive, and the issue seems a bit different, I'll upload a video.

All the accellerations are WOT in Sport. On the first 2 it is very slow, and boost is also to low.
3rd try is also slow, but then suddenly gets boost (to late) and after 5k rpm it kind of stalls a few times (you can only hear it once just before the upshift)...

Did you check that vacuum line(s) haven't blown off? Check the big intake hose on the throttle body too.

^ These suggestions are not linked to your codes, they're the easy-to-solve usual suspects.

I was watching his stock gauge and I know there not accurate but its going pretty far over in the white. Stock should only be around 10 lbs for a few seconds then drop back, if he is boosting 15 lbs. its over boosting isn't it ? for stock...

true, true

I did a quick inspection of the vacuum lines and hoses, nothing obvious at least. Also vacuum reads about the same as before, but it is of course possible.

And yes, at the end it seems to overboost... no idea.
You can see it on the other gauge... most of the time it stays at 0.5 which is about 7psi, 1bar is 14.5 psi, at the end I would say it was about 15.9psi

I'll investigate further at the weekend. But if a hose came off, would it even be able to overboost?

[matthew1]

Forget the video for a minute. What is the difference on that drive vs. last week? A touch less boost?

[hausmeister]

Yes, before the boost steadily climbed, now it doesn't, except at the very end
Power suxs, doesn't pull, doesn't sound right.
It drives OK in the lower rev range.
One minute It was running fine, then I tried to accellerate and It made a bit of noise and had no power... I guess from the symptoms it really sounds like a blown hose.

I'll guess pipe to intercooler, lower radiator....

[hausmeister]

Actually I think it is the ECU limiting the boost. It drives perfectly fine but the ECU keeps reducing the boost it seems.
I will disconnect the battery and set the wastegate To default which is ~1.8psi i think. Currenly i have set it To 3.2 psi which worked fine until now.

Edit:
ordered a pressure test kit for the turbo/intercooler hoses, that should eliminate any questions about leaks. I don't want to tear everything down and not find anything, with this it should be easier.
