Hey everybody,

Another "help me decode my codes" email...

Got an intermittent check engine light and following codes :

17535 p1127 : long term fuel trim multi bank 1
17537 p1129 : long term fuel trim multi bank 2

17965 P1557 : charge pressure control

Anyone know what these mean in English?

And on other threads that've gone by recently :

My (Audi OEM) battery died after about 3 years and it'd never
been discharged abnormally (lights left on, whatever).  I drive
the car every day and one day it just wouldn't even turn over.
Jumped it to get home, next morning same thing.  I thought for
sure something was shorting it, but nope.  Just a dead batt.

Sumitomo HTR+ : i'm running these tires now and they're fine/good.
Not super sticky by any means, but they wear pretty well (i got
over 20k on my last set), stick ok in dry, are fairly good in snow
and don't cost an arm and a leg.  I find them to be good (but not
great) at a lot of different things.  A compromise tire.

Also, just installed an AutoSpeed DTS.  Was wondering if i'd feel
the difference and i definitely do.  Sudden acclerations or
decellerations definitely feel much more immediate and solid.  That
kinda loose 'coasting' feeling while the drivetrain moves is much
