yep its a 5 speed tiptronic box.

 

Its dark out now and batteries have run out in my torch! will definitely get those enine/box codes tomorrow.

 

The main clunking takes place when shifting up from 3rd to 4th never when switching down. Ocassional problem with 2nd to 3rd, but less frequent.

 

I have managed to communicate with other ecu's, for example ABS/ESP steering wheel angle sensor. Also tried another diagnostic software called VW tool - seems to do all the same things as VAgcom, but looks different on the screen. Also seems to be unlocked i.e i think it will also do some of the things that vagcom does only when registered (recode etc).

Good, all the info I have given you is relevant.

 

Without baffling you with what clutch or brake does what in the box, I have had a quick look and seen that no specific clutch or brake in the box is engaged without more gears being affected. Put simply, with the gears you've mentioned, I would expect you to have issues with 1st and 5th also. Have you tried driving up and down the box in tip to try to pinpoint every gearchange for faults?

 

I have VWTool but, don't like it, a bit basic. I prefer Vagcom and with it being fully registered I can carry out all functions anyway.

have had an interesting development with autobox problem. A few posts ago I mentioned i did a basic setting on the autobox ecu, and it seemed to solve the problem entirely for at least half an hour then the box was back into its thumping mode. Thought i'd try it again today, and guess what, the box was smooth again. Switched off ignition and started up again and box became gradually more 'thumpy'. used 'VW tool' again to 'basic settings' and as you may guess box was smooth again. Switched ignition off again and back to thumping changes. It appears the ecu cant retain settings for some reason. Any ideas anyone?

 

BTW i assume its normal for there to be no workshop code or software code displayed in VAGCOM for the autobox ecu? I noticed some time ago that one of MrT's posts which lists all the modules etc in his 2.8 auto has software and workshop codes for other modules but not autobox ecu either.

ECUs only have this info when they require 'coding'. Your ECU does not require any 'coding' although it does require 'adapting' and 'basic setting'. When coding the ECU, a software code is generated and the corresponding workshop code is inputted from the diagnostic tester to the ECU. Coding is only needed when an ECU has the possibility of being used with different variants of engine, gearbox, etc. Yours is specific to that engine and box so does not need coding.

 

When adapting/basic settings, you are teaching in things like throttle angle, throttle pedal values, etc to ECUs that require it. Have you tried Basic Setting Channel 000 in Autobox ECU? Your autobox ECU learns and adapts to driving styles. Basic setting resets all learnt values, etc. I believe you have only tried Channel 063 in engine and this may only be half the cure.

 

Channel 000 in Autobox (ignition on, all electrical consumers off, engine not running)

 

- Select 02 - Gearbox Electronics

- Select 04 - Basic setting.

- Select channel 000.

- Confirm entry

- Depress accelerator pedal past kickdown to stop and hold in this position for 3 seconds

- The ECU is now in Basic Setting

 

how easy is it to clean the throttle body?

 

The throttle body is held on by 4 bolts and an electrical connector. There maybe some vacuum hoses connected and definitely the main induction pipe. I would remove the unit completely to prevent excess cleaning solution going in to your engine. I suggest cleaning the throttle flap (this will have to be manually opened and closed) and port with Carb cleaner and a toothbrush until all carbon deposits are removed. When refitted, the engine will need to be up to normal operating temp and basic settings channel 060 will have to be performed.

 

Basic Setting of Throttle Body (ignition on, all electrical consumers off, engine not running)

 

- Select Engine Electronics 01

- Select 04 Basic Settings

- Select channel 060

- Confirm entry

- Display should read 'ADP runs' (or similar)

- Completed when display reads 'ADP OK'

 

Hope this isn't too mind-numbing :rolleyes: , it does appear that your issue is more Electronics based.

i can confirm that the box is o.k for a day or two after i have been doing as you say:

 

"Select 02 - Gearbox Electronics

- Select 04 - Basic setting.

- Select channel 000."

 

after a couple of journeys the gal begins to thump into gear again, becomes gradually worse, but v v noticeable after a while.

 

it went in to a autobox specialist last week (he is the one that the local ford and VW garage send their work to). he is 90% sure its 2 of the solenoids being faulty. I assumed these would produce an error code? have looked on the net this may not always be the case - as far as i can tell , because it is an electromechanical device , it may test o.k electrically but be failing mechanically? i have TIS which does show how to test the resistance of the solenoids by putting a digimeter acros certain pins on the autobox ecu connector. (9-24 ohms i think).

 

not sure if i'm happy with a 90% sure diagnosis though. can anyone confirm this is the most likely reason for the problem. No fault codes in the ecu's at present, and havent been for a few weeks now.

just found this also from another forums

 

Hey fellas,

 

For the longest time, I've been looking for an alternative ATF to VW's VW TL 52162 (or G-052-162-A2, Esso LT-71141). I've been using Pentosin ATF1 for the last 2 changes. Now I see alternatives entering the market. Here are some info I found on the web...

 

Valvoline MaxLife: http://store.europarts-sd.com/ATFspecguide.pdf

 

Mobil 1 ATF: http://www.mobiloil.com/USA-En....aspx

 

Redline D4 ATF: http://www.redlineoil.com/prod...yID=8

 

Chevron Multi-Vehicle: http://www.chevron.com/product....aspx

 

Castrol Import Multi-Vehicle: http://www.castrol.com/liveass...V.pdf

 

Has anyone tried them?

 

 

also a few more links ( mods hope this is ok )
