Relates to a problem I posted few months ago that comes and goes. Its come back today whilst on a 4 hr car journey.*

Had the OBD tool on me so was able reset on the go and worked for a short time.*Error Code P0034 lists as Turbo Charger Bypass Valve Control Circuit Low

Read a few people says its the 2nd cat, take off, gently tap, flow hose pipe through.My issue is car autobox stays in one long gear, will change down but makes no odd's to power, makes it worse TBH.

So I keep it in drive.Car last week has not sounded right tbh, can't put my finger on it. Maybe the cat systems are block? Fuel hasn't been awesome last 2 months, but I can hear the turbo spool and no excessive oil use, infact normal.Any other ideas or soloutions?

Thanks in advance,Rich
