Hey Audizine,

I recently did a pretty hefty overhaul to my 04 Allroad 6spd manual with the 2.7t. I pulled the motor, removed the SAI, changed o-rings, turbo CHRAs, valve cover gaskets, timing belt, clutch and flywheel, swapped the trans to a Euro TDI trans, rebuilt the rear half shafts, new exhaust, new slave cylinder, and new master slave cylinder. After all was said and done, the car runs great, gets the MPG I was hoping for, and still is really fun to drive. However, I have one MAJOR problem, and that is that I lost my cruise control.

I was wondering if someone could tell me if there is a sensor on the trans I need to double check, or do I need to recode the ECU for the euro trans? Or did I somehow accidentally mess with the switch that is touching the clutch, if so which switch is it, and was it happened to be held in place by a little metal U clip (I found one on the floor board with NO IDEA where it came from), which is why I am guessing this may be it.

Thanks for your help, it is much appreciated.

John

Short version your tuner will need to fix it in the ecu, may not have done it before and may take a few tries.

I asked my tuner this earlier, and he said it doesn't matter...but I will look into it. Thanks!

Do you have vcds? If so you can use the measuring block to do some diagnosis on your own to verify your switches are working correctly. That’s where I would start

Does cruise work in lower gears like 1-3?

Since this is a final drive change also it may not.

If it does work on 1-3 just not say 6th then it's not any switches and the n/v stuff will need to get recalibrated.

Sorry been driving the car to much. :)

Yes cruise does work in all the gears except 6th. So I believe I need to recode the ecu. The cable I got for VCDS did not want to cooperate, so I am now waiting on the replacement. But if that doesn't work then I am going to just buy a ross tech and call it good.

I am hoping Sturkl is able to recode trans for me...but not sure he is willing to do that on top of a tune. Great guy to work with and Aaron has been very helpful.

Updates to come.

Thanks Dre for the link. I will be doing some reading. My wife REALLY wants the cruise back...my foot is to heavy without it. :D
