Radio Volume - PM6 Radio Coding Error - 01044

Have a 2009 GTI (MkV, TSI, CBFA) with annoying radio volume control problem. Even using its lowest pre-set, the car powers up with volume higher than I'd like it. When manually changing the radio volume, anything over about 5 bars (clicks up from zero) is really loud. So it seems the volume scaling function (volume per click) is messed up.

Below is OBDeleven scan which indicates problem with the radio's coding (radio appears to be OEM, but I'm not the original owner). See Group 56. AM/FM/SAT modes all work OK, as do all other radio functions.

Ross-Tech Wiki suggests attempting to re-enter the short code (in this case 0040401), which I've not yet tried. Thought I'd check the forum first, to see if anyone else has experience this problem and/or solutions?

The scan also shows errors with bass speakers, but all seem to be working fine (bass is OK) - certainly not an open circuit - maybe even a little too much bass sometimes.

Below is entire scan, in case there is some other clue in other modules. Have access to VCDS if needed, just don't have it here right now. Any Suggestions???

I take it you have adjusted the power up volume setting as well as the vehicle dependent volume increase?

I have the power-up volume setting programmed at the minimum allowed, which if I remember correctly is about 4 clicks up from zero. Even at that minimum value, it's a bit louder than I'd like. And that's true for AM, FM, & SAT. so I have to manually tap it down one or two clicks every time the car is started, regardless of where I had it set when it was last powered down.

I don't think there is a separate speed sensitive volume adjustment (at least that I know of). But even if there is, the vehicle is at 0 speed when powering up (so should be at lowest volume / speed setting).

The problem seems to be that each single "click" makes too much of a volume change. And it works the same way from either the radio volume knob or steering wheel buttons.

I'm ashamed to admit the above radio problem has continued to plague me, but didn't cause enough trouble to work on fixing it. Yesterday, I again searched for a solution and ran across this (my own) post, so figured it was time to finally do something.

Others have reported radio coding problems, most often related to getting their AUX jack to work, but none exactly the same as mine. I don't have the AUX jack in my glove box, so there may be a number of radio options for MKV GTI's, and your exact code solution might be different .....

Anyway - I've managed to solve my problem. My PM6 radio was coded as 0040401, worked OK other than the non-linear volume control response described above, various speaker faults, and a 01044 Control module incorrectly coded error. Cleared faults immediately came back.

So after considerable experimentation using VagCom's coding helper, I'm now using Code 0040432 - the "32" change refers to my (3) Cloth Interior (w/o open ckt recognition) and (2) CD Changer / I-pod Connection - which is in the center armrest - although I've never tried to use it.

The car now seems happy, has stopped throwing radio code / speaker errors and my volume control seems more linear per each step. Will know more after I've lived with it for a while, but I think it's fixed.

Hopefully this will help someone else who has grown tired of their radio always powering up at high volume!
