Woooo! Got my first SES light about a week ago. A moment for the baby book, they grow up so fast :hihi:

So today I spent all day today getting INPA setup so I could read the codes. As a result, I don't have the hex numbers, I found a list that has the regular long form versions.

I got the following codes:
143 - E-Box Fan
57 - Mass Air Flow Sensor Left
77 - Intake Air Pressure Sensor (DME Internal)
75 - VANOS Retard Valve - Inlet Bank 2
74 - VANOS Advance Valve - Inlet Bank 2
178 - Catalytic Converter Efficiency Bank 1
210 - Misfire Cyl 6 without Cyl Cutout
211 - Misfire Cyl 7 without Cyl Cutout
213 - Misfire Multiple Cylinders without Cyl Cutout
208 - Misfire Cyl 4 without Cyl Cutout
209 - Misfire Cyl 5 without Cyl Cutout
174 - Fuel System Diagnosis Bank 1
72 - VANOS Retard Valve - Inlet Bank 1
67 - VANOS Advance Valve - Inlet Bank 1
179 - Catalytic Converter Efficiency Bank 2
149 - Fuel Level 150 DME Memory Fault

:confused3

The only thing I've done recently is replace the MAFs with the VW Bosch models. I probably wouldn't have purchased these myself, but the PO purchased them and included them with the car. From what I was able to find, lots of people are running these with no issues, so I'm not really convinced they are the problem. The only other thing I've done recently that seems like it could affect the engine is I replaced spark plugs and performed the vanos solenoid boards maintenance.

I replaced the MAFs before the I did the board maintenance, and I didn't get an SES light. The car felt better afterwards. I performed the vanos solenoid boards maintenance and the car felt better. It eliminated this phenomenon where the car would knock once if I stabbed the throttle at idle which was awesome.

The car didn't throw the SES light until a week or two later on a very cold morning. The light came on but nothing felt wrong, the car ran fine. However, ever since that morning my mileage has been disastrous. I'm averaging like 12.8 mpg and I can tell the car is running rich. The only other issue is the throttle is really odd and twitchy until the car is warm, at which point it pretty much goes away. Other than that the car feels normal.

As this is the first time I've pulled codes, I'm not sure how long any of these have been around. I decided not to clear them because I wasn't sure what the next step is. I did read that after an MAF replacement it may be a good idea to resent the adaptations as the new sensors could throw off the adapted relationship between the MAFs and the oxygen sensors. Is this true? Should I try it? Not really sure what else to say. Looking at that list it just doesn't seem like any of those are really happening judging by the way the car drives.

Any advice would be greatly appreciated.

Cheers!

Clear the codes and drive it for a week / or until the SES comes on again, then pull the codes. If you haven't cleared them under your ownership, all bets are off.

Ok I cleared the codes this morning and so far so good. I will report back when it comes on again. In the meantime I'm going to check the fuel trims during lunch today as I'm still averaging like 12.8 mpgs...

Stalls and had to tow home

First time I've been stranded by the car since purchased in 2007. Had to get towed home and used the Peake reader. See the video for codes. I think I read it right "Air fuel adaptation bank 1 &2. Fuel control bank 1 & 2, fuel pump relay, " but I could be wrong.

4. The first thing a Peake reports is a table number. No matter what you see, look up Table 18.

FWIW I just got a new Peake reader (from an eBay seller not Peake themselves) and it told me to go to Table 1b not 18. Are we all still 100% sure this means the reader is defective or something? How was Table 18 proven to be the only possibility? I see more than one reply in this thread where people are getting 1b as their table.

edit: I just spoke the man himself Dan Peake. I told him about this thread and the 18 vs. 1b showing for certain people. The Peake tool is NOT BROKEN. Our ECU's have multiple hardware revisions and/or processors. Dan thinks his tool "chokes" on a few of these and shows 1b vs. 18. We are definitely supposed to be using table 18 as stated above.
I also counted up 208 codes on table 18 and only 182 on 1b. I asked Dan if the tool reports 1b when it should have said 18 is it now looking at the wrong table and therefore "hiding" 26 codes or unable to show all 208 to users. He stated clearly the answer was no and that the tool will display all codes correctly. The displaying of the table and the searching of the codes are unrelated. They're going to update the manual to explain this "bug."
