Gear selector

2004 R5 6 speed auto.

The PRDN display has gone out and the car is driving strangely, it's jerky.
The S and gear up and down functions don't work either.

I looked on the fuse cards and can't see anything that looks like it might be it.

The ESP light is on, pushing the button changes nothing.

Anyone know what it is?

I would be looking to do a VCDS scan. There is a good chance that it has nothing to do with the transmission, and may be it s missing a signal from a related component such as ABS, Stability Control (ESP) or similar. At least a scan will make the list smaller..

Thanks Styuart.

You don't happen to know anyone in Brisbane who charges less than $150 per code do you?

Does the transmission range selector have a fuse?

It looks like it will probably be the range multifunction switch.
Can anyone tell me where i'ts located?

Problems with the gear change can sometimes be down to the selection magnet on the underside of the sliding "blind" that surrounds the base of the gear lever falling off.

VW Touareg models are as follows:
Generation 1: T1 is model 7LA & facelift T2 is model 7L6
Generation 2: T3 is model 7P5 & facelift T4 is model 7P6
Generation 3: T5 is model CR7 [Not available in "VW Atlas" North America!]

I've heard about that; don't all the PRDN21 lights come on when that happens?
I don't think it explains the other symptoms.

No. I mean anything might happen - but it's neither typical, not necessary with magnet problems.

Jerkiness is not a typical symptom for a magnet problem. However, inability of selecting S and/or not being able to shift manually up and down are.

Also, if any of the two magnets got lose, they could cause all kinds of weird problems with gear selection and shifting. Because they could randomly move around, and because there's an electronics board right below them, which they could short circuit, or generate implausible signals on.

Anyway, as already suggested, you should do a VCDS scan first. The reason for your problems could be literally anything, and without a proper scan, all you can do is guess blindly what's causing them.

$150 per scan and last time I got them to do a scan they were wrong. Besides, they're not open for at least another week so it's guessing intelligently for the the time being.

I found a thread that showed in great detail how to get into the magnets, but the pictures were gone.
I'm downloading elsawin, only 18 hours to go!
A helpful member sent me a disc with elsawin on it when I first got here but I can't get it to set up.

So far in my searches I've seen reports that neither the magnets nor the multifunction gear switch faults show up on VCDS.

Yes, I think so. Would pay for itself quickly at these prices.

Heh, I saw somebody selling cables for $2 each! Yes, $2.00AUD. Had to buy 18 of them to get it at that price.
