MFTS -could- be sending an overheat, but I don't think you'd get
anywhere near 1.7bar indicated if that was true; also, the AC would
stop working.  On the 200q20v, for example, you get about 1.3 bar
because the ECU completely turns off the wastegate frequency valve.

Well, at least on the 200q20v, the computer display changes to being
"scaled"; 1.8 bar indicated is actually much more, since you have a
different pressure sensor.  If Ned thought you were saying you had an
external gauge and it was reading 1.7, that might be one source of
confusion.

Also, Bentley specifies a boost test of 4th gear, 2k rpms...nail it,
and you should get full boost by around 3k.  I thought I wasn't
getting full boost once and something was amiss, until I tried it.

200's have the slot on the FPR, but it doesn't dump the codes.  See
SJM's site for the pinout on those 3 connectors down below; you can
hook up a test lamp and jumper two terminals to get the codes.  If
the bulb is in the dash, basically, you just need a small piece of
wire(paper clip will do in a pinch, BTDT :-)

Only California cars had the check engine bulb installed.

Taking the wheel off...hmm.  Probably does make things easier :-)

It is a -major- PITA to get the cluster in+out without removing the
wheel, but it can be done...after a lot of cussin' and fussin'.
BTDT, 3 times, and it's still not "easy" for me.

HTH!
