[s-cars] I want my MPG

i looked more closely, and found a description for group 001.  as for group 002, "contains no useful information that can be applied to customer servicing".  groups 003-099 supposedly display the same values as group 002.

my group 001 
rpm temp lambda btdc
800 95.2  1          9.8

i'll paste in the CSV file from the logging for group 001, because i'm not sure if i should be seeing more crossings for lambda.  the sampling period is about 1.2 sec, so that may not be fast enough.


Group B: '001

by the way, anybody know where to find a description of the other groups in VAG-COM?  group 003 showed the last block with the label "temperature" and the value was between 58 and 65 degrees C.  is this intake charge temperature?  a quick read of bentley turned up nothing about group 003 in bentley - or any group other than 000, for that matter.

i just used VAG-COM on the car.  it's reading 206, which according to bentley, is within spec (range 184-215 and appears to correlate to 185-220 deg. F).  i was looking at group 000, block 1.  bentley says this field is the engine coolant temperature.

here's group 000:
206 022 080 128 098 129 056 129 066 037

note that block 9 has a value of 66.  this is O2S adaptation, and normal range is 100-141.  the car was pretty hot after a 20 mile trip on the freeway, and a short stop at the store.  i got home and left it running while i ran the codes.  block 8, O2S control, is 128 (spec 123-133).  i already tightened the clamps on the samco hose between the MAF and the turbo.  not sure what's going on here.

shop said the O2 sensor was OK, but maybe i should replace it?

-t.

Mark:  I know you suggested the temp sensor before.  That is why I made my earlier post,
regarding the location and function of the G62 temp sensor:

I think that your temp sensor suggestion was an excellent one and that
Teddy should pursue (sp?) that one over all others (at least initially).
