Had the check engine light come on during a recent road trip, the day after the TB/Pump service + Oil Change was done at the dealership.
Brought it in yesterday & was told Bank 1 - 1&2 Sensors are not working.
THe codes:

17521 P1113 035
Bank 1, sensor 1
internal reisitance too large
sporadic

17526 P1118 035
HO2S Heater Control Circuit (Bank 1 sensor 2)

17522 P1114 035
Bank 1, sensor 2
Internal resistance too large

16524 P0140 035
O2 sensor circuit, Bank 1 sensor 2
No activity detected

Questions:

1. I've had the car since the 14th. At no time did the Check Engine light come on - until the TB/Pump servicing & oil change was done - any relation? We did do an extended trip ( about 2.5 hours @ 80MPH + )& I understand sensors aren't a lifetime component & do fail.

2. Is this price bananas? I'm out of my league on the mechanics, so DIY ain't an option.

3. This is a VW dealership (Middletown VW/Mazda)with certified Audi techs, but my wife was recently to Jack Daniels Porsche/Audi in New Jersey to have a valet key cut/coded and was impressed.....any history in dealing with them somebody can relay?

4. Has anyone submitted this sort of thing to a 3rd party Service Warranty? I bought the car at a regular used car dealership & it came with a 6 month warranty from AutoSource.

Thanks!!

...checking into, anyway.

Also, as a former owner of a 2000 2.7T (driven until it had 99K miles), do yourself a favor and BUY A FULL, ZERO-DEDUCTIBLE extended warranty. Whatever it costs will be WAY less than you'll run up in replacements/repairs over the next few years.

I know whereof I speak.

Get the generic Bosch O2 sensor from Blaupoarts or ECS ($90 + sh). Works great.

at the same time? Me thinks they caused a bad connection, and should fix it free of charge. Oh, and $850 to replace upper &amp; lower O2 sensors is laughable - I can do them both in two hours, and I'm S-L-O-W. Not sure what the part price is, but that total is *NUTS*.

FYI, the check engine light didn't come on immediately upon leaving the dealer because I believe the ECU needs to see a persistent failure (~50 miles) before declaring a fault.

Suggest you visit dealer again, with a 0.40 caliber - Smithfield Armory makes a nice alternative to the Glock if money is tight.
