Can the ASV/Throttle Plate be cleaned, repaired or must it be replaced when it throws a code????

Try cleaning it first. Remove it to clean, being careful not to get any solvents in the electrical parts. The you will need to recalibrate it be resetting Group 00 in the adaptation of the engine ECU (it will recalibrate eventually, this way is just faster). There may also be something in basic settings, not sure off hand though.

And if cleaning won't work, then you will need to replace it.

OH, is that a stepper motor in the ASV? It looks as if it is homing when you first turn the key on..

Thanks..

It is not an anti-shudder-valve, that is merely one of its several functions, and a rather minor one at that.

Yes, there is a motor inside, just like the electronic throttles on the gassers.

Default Same problem sort of....

First I am new to this forum but this has been fantastic with the pictures and the help. I had the dreaded gear strip in the flapper valve on the black half gear. Must have been stuck on start up then continued to strip it out. The electric motor still works, does anyone rebuild these flapper control valves or have a link to after market - I hate to go to the dealer for a 50 cent gear and have to buy the entire assembly for big $$$$$

I just found this thread and am thinking I have the same issue with our 2006 TDi. It throws the "Emissions Workshop" warning up and the ENGINE LIGHT shows up on the panel. It does not seem to affect power or mileage. I pulled the code with my OBD2 tester and got the P2112. My tester says this condition is "Generic Throttle Actuator Ctrl Sys - Stuck Closed"

Is the fix likely to be the gear that controls the ASV flapper?

I also read that there was a TSB for the intake flap motor but we never got any notice from the dealership so I am not certain it applies to our Jetta?

Thanks

You probably need a new intake control flappy thingy (throttle body).

Default part numbers for anyone who needs them

No time to tear it apart last night but I followed up with the local stealership today and explained the issue. The VW part number is 03G 131 501AD and they quoted me $346.95 for the part.

Rock Auto has two parts listed for this - it was a little clunky to navigate their site but for our 06 TDi I went under the year, then Jetta TDi and under EMISSION then EGR. They list :

STANDARD MOTOR PRODUCTS Part # EGV1081 $277.79

and then

AIRTEX Part # 4F1959 {#03G131501D, 03G131501N, EGR4409}
03G 131 501AD at $313.79

1stvwparts.com shows the following- BEST PRICE I COULD FIND

03G131501N $347.00 $0.00 $257.13 Emission system - Emission components - Egr valve
Egr valve - 1.9 liter 2005 - 2006

I have had excellent results from 1stVW and RockAuto in the past but if i end up having to order one I'll be on with 1stVW. I do wonder if the new number is a new part vs. the number 1stVW uses may be the old (crappy?) part.

Will post more once I can tell you the outcome

The EGR valve is not the same as the intake manifold control flap, and the EGR valve is available two ways. One way it is $245, the other is $330 (VW list prices, approximate). Just depends on if you want the flange with it or not.



The throttle body, or 'regulating flap', part number 03G-128-063-G is $275 IIRC.

So to clarify, the part number I had is for the whole assembly WITH the EGR and your p/n is just the Throttle Body and ASV flapper w/o the EGR?


1stVW still has a better price

Item Number MSRP Core Price Price 03G128063G $283.90 $0.00 $210.37

Hmmm reminds me of my icemaker experience. Wanted to charge $127 for a new unit as the gear was not available by itself. I carved one myself using the broken pieces as a guide. Still going strong 5 years later. Same thing on my aircon controls on a 99 Tahoe. $400 and a new control panel later I test and find one blown resistor that RS gave me for free as a replacement. Kept it as a spare. Seems like that is the new trend. Can't buy parts, you must buy assemblies now.
