raketeS4~AlmostFixed

lately i've been getting bad shudder when coming off the gas and i assumed i was just in need of some new motor/tranny mounts, but then i threw a check engine light last week and that got me thinking. i searched the archives and i was thinking it's probably a bag EGT sensor, and then today the car went into limp mode so that basically sealed the deal. i just ran out to the car and these are the codes i threw:

Address 01: Engine
Part No: 8D0 907 551 B
Component: 2.7l V6/5VT G01 0003
Coding: 06651
Shop #: WSC 40821

7 Faults Found:
17965 - Charge Pressure Control: Positive Deviation
P1557 - 35-10 - - - Intermittent
17521 - Oxygen (Lambda) Sensor; B1 S1: Internal Resistance too High
P1113 - 35-10 - - - Intermittent
17861 - Exhaust Gas Temp Sensor 1 (G235): Open or Short to Plus
P1453 - 35-00 - -
17526 - Oxygen (Lambda) Sensor Heating; B1 S2: Open Circuit
P1118 - 35-00 - -
17522 - Oxygen (Lambda) Sensor; B1 S2: Internal Resistance too High
P1114 - 35-00 - -
16524 - Oxygen (Lambda) Sensor B1 S2: No Activity
P0140 - 35-00 - -
17539 - Oxygen (Lambda) Sensor; B2 S1: Internal Resistance too High
P1131 - 35-10 - - - Intermittent
Readiness: 0010 0001

From what i can tell, the positive boost deviation means my boost spiked too high? how can the car tell that if I have a TCD? the EGT fault means my EGT sensor is shot right? is sensor #1 on the driver or passenger side bank? what do the other O2 sensor faults mean?

I think you need to change the EGT,O2's all together.

you sould only care about the s1 sensors. since s2 are for emitions only.
get zoldman from vast performance.

I need to pass my emissions in CA and this is the first step in the costly exercise.

DxC

no low cost source, they are like 200 bux a piece

Mr.Debo'sS4

I have been quoted higher - where is the $ 200 source?

HdiaS4

i would try carlson first and see the price.
its about $220 or so per side.

if you can get it for less than $170 is a very good deal.

So you kept the car? Nice! FYI, I just passed CA emissions with 200 cell cats

DxC

wow really? more than 200 now? ouch. i bought them online a year ago for 170. i should buy theirstok
