Are you saying it takes 6-8 hours just to get to that lid?

No, it's only about 90 minutes to get to that stage of the game, and up to that point, the disassembly is reasonably easy-going. Removing the aft portion of the top cover, then removing the fan motor takes another couple of hours. Removing the aft portion of the top cover of the airbox (which contains the recirculating flap motor) is the extremely difficult and frustrating part.

I will do a write-up as soon as I have time, but it is going to be a long and complex write-up (will take several hours to do it), hence I might not be able to get around to it today or tomorrow.

I think most of us just have trouble with the fresh air flow flap, the one you have out in that picture. The recirculation motor is the one you have to go prospecting for past the blower motor. The repair manual does call that one out specially as "very difficult".

I am getting this motor replaced starting next Monday; the tech has no idea when he is going to finish. I am hoping that Michael may have had time to post some of the dos and don'ts that he said he encountered when he changed this motor in his car. According to the tech, the entire dash unit has to come out.

Well, I finally had the two V71 motors replaced. It took the tech about 5 hours, but he did not have to take apart the dashboard. According to him, the new repair manual instructions show how to do it from the engine compartment - without having to remove the engine. The job would have cost $1374 including parts and labour. Fortunately, the warranty company paid for it.

How does one find out what specific tools are needed for this job? Do I need a repair manual?

Interesting this came up right as I'm digging back in to my A/C issue:

http://forums.vwvortex.com/showthre...for-00716-Air-recirculation-Flap-(V113)-not-working-Already-replaced-motor!-too!

After reviewing this today, I discovered I replaced the V71 motor and not the V113 that I need to replace. I got to the V71 in about 2 hours without a manual/instructions to help. I don't recall any special tools beyond torx an/or hex bits for screw removal, but I did it last fall so I don't recall completely what it took to get to. I do remember loosening the wiper motor bracket assembly to gain access to a couple screws. I also missed a couple screws that were under a wiring bundle, so watch that. I didn't think getting to V71 was especially hard and had I needed to do it again last fall, I don't think it would have taken more than half and hour, like I mentioned in the thread I linked above.

This thread tells me the V113 is MUCH harder to get to. I guess I know what I'm doing all day this Saturday. I'll keep my eye on this and other threads for any tips to help dig down that deep to get to the V113.

I am about to order V71 motor, but it looks like V71 and V113 are the same thing (stock code 4D0820511). So, are these two parts really the same thing for use in different places?

Pretty sure they are the same based on my experience. My trouble code indicated the V113 is the problem on my car. Last fall I mistakenly replaced V71 with the part I ordered for the V113 location. The removed part looked identical to the new and worked fine, meaning I didn't get a new V71 error code after the install.

It's just a small servo motor to open and shut a damper. No reason for them to be different.

Hi Brad,

The V71 and V113 are explicitly shown in the parts diagrams and lists as using the same motor, having the part number you quoted.

It is also used on the pre-2004 Audi A8 and S8 Quattro. It is about $150 from VW or the usual on-line suppliers.

Unusually we've had a few warm days here in the UK. Yesterday I noticed that, having been blowing cool air, the passenger left side front air flap failed to close when I turned off the ignition. The centre and right flap vents did close ok. A couple of weeks ago I noticed the left vent closed a little slower than the others, but it then seemed to rectify itself.
I have done a VCDS scan on the car and note the following fault:

Address 08: Auto HVAC Labels: 3D0-907-040.lbl
Control Module Part Number: 3D0 907 040 L
Component and/or Version: Climatronic D1 2035
Software Coding: 0000001
Work Shop Code: WSC 01065 000 00000
VCID: 275D211792BBDA26FAD-8072
1 Fault Found:


01274 - Air Flow Flap Positioning Motor (V71)
005 - No or Incorrect Basic Setting / Adaptation

I went into the HVAC controller and ran the sequential tests. Everything worked well other than the Left Air outlet blind motor (V207) which did not operate, although the air flows seemed to change as they should. i.e. the motor did not close the flap but everthing else is okay.

I tried to reset the flap motors by going in to the adaptation channels on VCDS. Changing bank 1 to value 2 set off a sequential test where the centre and right vent flaps went through a reset from closed, to half closed, to fully open. The left flap did not operate.

Looking at the V71 settings they are as follows:

Address 08: Auto HVAC (3D0 907 040 L)


19:13:11 Group 017: Flap Motor V71/G113: Outside Air Flow / Backpressure - Under Hood Plenum
182.0 Current Value
182.0 Specified Value
182.0 Minimum Position Blocked
182.0 Maximum Position Open


The car in under warrantee, but if it is an easy fix I'd rather do it myself so as not to jeopardise any future claims. Any ideas please?

Thanks - Glynn

Chris, is the V71 the motor that controls the wood panel, or the flap motor that controls the air flow, or are they one and the same?

Sorry, I was commenting on the earlier discussion that implied the decor panel motor might be stiff, rather than the later discussion of the V71 DTC. Perhaps a sticky internal flap might be partially compensated for by the system unexpectedly keeping open a fully-functional decor panel.

The V71 is one of the internal flap motors, the decor panel motors are V207, V208 & V209. I have no access to parts lists at the moment, so I can't check if the drive motors are the same part number.

Are you using a wiper arm puller? There is a special tool that screws in on the shaft while pulling up on arms that lock onto the wiper arm. They are cheap.

It is a press fit, so typically you just crank until it *pops* and then it is loose and lifts right off.


Hop on Amazon.com and type in wiper arm puller.
