VAG-COM Error codes from my car ...

[Rybky]

VAG-COM is showing me the following errors:

Address 01: Engine Labels: None
Part No: 066 906 032 AJ
Component: MOTRONIC ME7.1 G 0002
Coding: 00031

3 Faults Found:
17704 - Error in Mapped Cooling System (check Temp-Sensor and Thermostat)
P1296 - 35-10 - - - Intermittent
16523 - Oxygen (Lambda) Sensor B1 S2: Response too Slow
P0139 - 35-10 - - - Intermittent
16795 - Secondary Air Injection System: Incorrect Flow Detected
P0411 - 35-10 - - - Intermittent

Address 08: Auto HVAC Labels: 3Bx-907-044.lbl
Part No: 3B2 907 044 C
Component: CLIMATRONIC C 2.0.0
Coding: 110001

Fault Found:
00603 - Footwell/defroster Flap Positioning Motor (V85)
37-10 - Faulty - Intermittent

The first and second are self explanatory, is the third one the MAF? And what is this footwell/defroster flap positioning motor? Is it hard/expensive to fix?

Thanks!

Hi Adam, I beleive its the same as the recirculation flapper, and its under the dash in the passenger footwell. I had this error once, cleared it and it's never come back. BUT there is a distinct servo-clicking sound occasionally but you can temporarily reset it by turning on the AC and selecting Recirc. BTW it a real PITA to fix by previous accounts.

Other than that, looks like the VAGCOM cable did the trick for troubleshooting... not sure about that Secondary Air Injection System: Incorrect Flow Detected error

Ah! I could hear a clicking sound from the centre of the dash, thought it was something to do with having the cable attached. Will try resetting the code and see if it comes back.

I wonder if that Secondary Air Injection System error could be because of the split vacuum hose?

Go to the ross-tech.com wiki and look up the codes. Or google them. Usually worth deleting and checking what comes back.

Good call Gavin! Found the secondary air injection one on the wiki here: 16795/P0411/001041 - Ross-Tech Wiki

All sounds quite vague though, quite a few things it could be. One of them is pipes/hoses between components so maybe, just maybe, it is being caused by the split vacuum hose I found (see other thread). Will get that replaced first, reset the codes and see how it goes.

That's the problem when there's more than one thing that could set off the code. You just have to use your imagination a bit and think outside the box.

Boost leaks for example, usually snag the diverter valve, not very often a problem cos most folk have replaced them. It's just the only thing the ECU has control over that could be causing the leak.

OK, so 5 days after changing the breather hose (aka vacuum hose) the only fault showing on the VAG-COM now is:

1 Fault Found:
16523 - Oxygen (Lambda) Sensor B1 S2: Response too Slow
P0139 - 35-00 - -

Definnitely need to get that replaced then. Not sure how the breather hose has fixed the coolant sensor but hey, VW's work in mysterious ways right?!

Coolant sensor code could be from 5 years ago and hasn't been cleared since being fixed?

Like your thinking Gavin but a dealer reset the codes a few weeks ago after seeing faults from the MAF, O2 and Coolant sensors, so the coolant sensor fault I saw on the VAG-COM (in my OP) occurred after that reset.

I have ordered a new O2 sensor from ECS today and while I was at it ordered a coolant sensor too as they are not expensive, might as well change it at the same time and know I have a good one in there.

Did you order the coolant sensor clip with the sensor itself?

You should be getting the green coloured coolant sensor (the black one is now considered obsolete).

Errrm, nope, didn't know I needed to. Do the clips break easily then?

ECS only sell the green ones, went for the cheaper generic brand rather than OEM though.

There is a rubber O ring as well.

Should only need the o-ring and clip if the existing ones are no good. Given the potential age of the stuff, they may be worth having.

That said, I think the sensor comes with an o-ring anyway.

For what it's worth, the cheaper generic one you've ordered is probably exactly the same as the genuine one other than a VW/Audi stamp on it - ECS's non-genuine parts are mostly OEM/OES (Original Equipment Manufacturer/Supplier).

Yes it does come with the o-ring but not the clip, hopefully the clip I have will be ok, will just have to be very careful removing it.

That's what I figured, just like prescription drugs!
