audi A4 2005 2.0 problem

[ahmadmuqbel]

Hi guys,

i need help please with my audi A4 2004, recently i had that PNDR flashing problem from transmission and sometimes i couldnt get car to reveres, so i took the car to the dealership and after checking it they said that i have to change the TCM, so i changed it and i paid a freaken 4000$ !!

the problem is when i got my car back, it feels very heavy, like motor braking all time,, as soon as i remove my foot from pedal car decelerate and lose its speed and like if i go downhill car would raise rpm and it wont upshift.

i took it to dealership many times ,, and every time i leave it and they say that there is nothing wrong with car. however the problem is still there.

im very frustrated especially after paying that amount of money,, any help would be great!

It sounds like the TCM has not been synced to the car. A new TCM has to be put into "learning mode", otherwise it will have erratic shifts, shift up too late, or downshift too early.

I take it, this is a FWD car, with CVT, right?

[ahmadmuqbel]

So what should i do? Everytime i go to dealership they test it add say everything is fine

[ahmadmuqbel]

And yes it is , FWD CVT

[ahmadmuqbel]

To add , even when i change to R now , the gear doesn't engage directly, like if i was on inclined road and car front is facing downhill the car would move downhill for like 30cm before the R gear engage.

It sounds almost like the engagement points are wrong.

What does the car idle at?

[ahmadmuqbel]

About 1000rpm ,, but let me check,not sure

I don't know if there's a difference in the transmission, but I know there is in the engines. You have a B7 if you have a 2.0T.

[ahmadmuqbel]

No its not 2.0T ,, its 2.0 and dealership said that they brought the exact TCM for it regarding its VIN ,, "thats what they claim at least",, and Nollywood i will check the rpm when my old man comes home, its his car, should be here after few mins

[ahmadmuqbel]

It sounds almost like the engagement points are wrong. ?

Btw it was perfectly fine beforw changing TCM , just sometimes R wouldn't engage, but transmission engagement points was perfect, the car is for my father and it has only 50000 km and always maintained

If it's a 2.0, it has a turbo if it's an Audi. Unless you meant 3.0?

The B6 in Europe and Australia, was available with two 2.0 litre motors.

1984cc I4 20V, 130hp.
1984cc I4 16V FSI, 150hp.

I think you'll need to pull codes, and post the results here. It's possible the dealership's giving you a snow job.

Exactly and ours is the 20V ofc since auto

So i should go to some shop with Vagcom ? To pull codes ,, because whenever i go to dealership they say no faults ,, and charge me, so stupid

[ahmadmuqbel]

There is no check engine light or any warnings on dash ,, does it worth to disconnect the battery for while ?

[Nollywood]

Yes, you'll need a shop with VCDS, or at least the equivalent, that can scan the TCU. You may not have a check engine light, yet still have a code stored in your TCU.

The indicator that shows PRNDS or similar on your dash, what's it like? Is it any different from normal? Is it showing the selected gear, or is it all lit up? I can't remember what a CVT indicator is like.

[ahmadmuqbel]

The indicator on dash is fine,, it have a square to indicate the selected gear, so its normal

[ahmadmuqbel]

Its really annoying issue,, i searched the net for long ,, theres nothing about my issue,, i will do as you say and go to some shop to scan TCM
