[s-cars] occasional slight over-overboost

[Tom Green]

It still could be the WG sticking, JC.  Worth investigating anyway.   
See if
backing off a turn or so helps or open the WG to make sure the piston is
not coked up and sticking.

You can just flash the codes out as well.  I had that problem with my  
old
Compaq laptop.  The battery was fairly new but would shut down after  
only
30 min so I always plugged in.  I think it weighed 20 lbs  as well.   
The 466
AMD processor would not run VAG-COM on the USB port;  serial only.

So I saw this deal at Sams.com for the Dell mini netbook, 9" screen, for
$245;  makes a nice small package that works great;  another $159 for
the USB/CAN version trade in though.   I would have paid all this to put
windows on the Apple laptop.

The MIL light can flash faster than you can see it and still drop a DTC.
Unless they record as intermittent they stay in memory;  the  
intermittent
codes drop after 60 starts if not recorded again-or something like that.
This means intermittent fault, not intermittent MIL.
