NOTE: There is a well meaning video on Youtube where the guy takes out the entire seat on a T1.

You do NOT remove the seat on a T1 or a T2 - it hinges backwards.

But you do remove the seat on a T3! HOWEVER, as of 20 October 2014, go and look at post #72 before you take the T3 seat out as it seems it may tilt back as well!


20 October 2014:

I have added a new and correct video at the bottom of this first post for T1s and T2s. This video shows how to tilt the seat backwards.

BUT . . . do press the tool into those floor bolts much more firmly than this guy, especially if you are undoing them for the first time [he wasn't as it wasn't an OEM battery that he took out!].

When the cars left the factory those bolts were done up super tight and with a locking compound too!

See post number 6 for the V10 how-to

See post number 56 for the T3 how-to with pix!

VW 2003 3.2 PETROL TOUAREG BATTERY REPLACEMENT:

The battery is situated beneath the front passenger seat on right hand drive cars and under the driver's seat on left hand drive cars.

NOTE: If you provide a 12 volt electrical source to the battery terminals under the bonnet while you replace the battery it will keep the radio, GPS and convenience settings as well as avoiding the disconnection creating any VAGCOM fault codes.

Here is a diagram of the under bonnet battery terminals in the rear right hand corner of the engine bay when looking from the front of the car:

http://www.automanua.../images/137.jpg

At the front of the passenger seat . . .

There are two grey plastic covers lying flat on the floor at the base of the front of the seat.

The one nearest the transmission tunnel is held by a single spring loaded metal clip: pull the cover up to release it.

The one nearest the passenger door is held by two fragile plastic clips so ease it up evenly and gently!

These actions expose two seat bolts [one on each side] on the floor: remove both bolts.

WARNING: These bolts require a 10mm "triple square" male tool similar to the Torx 6 point star fastener except it has 12 points instead of 6..
Without this tool you will NOT replace the battery! The bolts are torqued to 45 NM

At the rear of the seat . . .

Carefully remove the plastic trim from each side at the rear of the seat slide assembly by gently bending each one outwards first and then sliding it towards the rear of the car.

This exposes two more seat bolts on the floor [one on each side]: DO NOT REMOVE THEM!
The seat mounting brackets are hinged at these bolts and the seat rotates backwards [but do NOT try to move it yet!].

Accessing the battery box . . .

Tilt the backrest of the passenger seat forward as far as possible and then slide the seat forward as far as possible – this is important to create space to remove the battery.

Now push/pull back on the seat backrest and the entire seat will rotate backwards on its floor mounted hinges and will expose the battery box.

WARNING: Check you do not pull or snag wires under the seat whilst tilting it!

Unhook the four clips that hold the battery cover on.

Remove the Torx screw holding the heater deflector to the battery box lid.

Remove the tie holding the wiring to the top of the box.

Remove the box cover to expose the battery.

Remove the gas vent plastic pipe from the front.

Remove the metal cover at the front left corner [10mm socket]: NOTE that it will not come out until you disconnect the negative battery cable so do not disconnect yet.

Remove the side clamp [10mm socket] and the battery is now loose and free.

Disconnect the terminals and lift out the battery.

Re-assembly . . .

Reinstall it all the opposite way to how you removed it.

NOTE: Apparently VW recommend replacement of the two front seat bolts as they are intended for one time use so it’s your choice whether you do so or not.

Torque the two seat bolts to 45 NM.

Good advice. You need to be very careful that you engage the socket in the bolt head splines very securely.

I found, as have others, that the factory torque settings can be way, way out requiring huge effort to shift the bolts so unless you've really secured the tool in the splines, you can come badly unstuck!

Need to change the battery under the seat of my V10.

Dose anyone know a code(part number) for an equivalent battery? i.e. alternative to the VW original

There seems to be plenty of info around on the rear battery but none on this one?

Ref the tight bolts: if these seem tighter than the specified torque I guess they could be done up with studlock?

I have the 12 point tool ready.

Thanks

A big "THANK YOU" to NoobyT for bumping this up. A great piece of clear instruction on how to replace the battery. My battery charged up fine and showed as "strong", however would only hold the charge for 3 days. I was keen to do a diy replacement as on my old V10 Treg a main dealer had charged £450 to replace!
NoobyT's instructions were spot on and gave me the confidence to do the job myself. Went for a silver Varta with a 5 year warranty. NOW FOR THE INTERESTING BIT - the battery I took out was the original black Varta dated wk 31 2003, so a smidge under 10 years old! Pretty impressive. (On Varta, the date code is stamped wk no / year on the Negative terminal).

Btw, I changed my V10 as I use the Treg infrequently and I was worried about such a big complicated vehicle sitting on the drive doing nothing most of the time. I went for a 2003 fsh 2.5TDi manual box i.e. no complicated air suspension or Tiptronic box. I took forum advice and chipped it and I love it! A great piece of kit for little money and now not much depreciation.

(Looking forward to some inclement weather so can have some "Treg fun").
Cheers,
Chris.

hi, just been to BOWERS auto electrics stoke on trent and they did a free battery test including lifting the seat and told me it needs a 24 hr. Charge then a free retest. If it needs replacing they qouted £89.49 inc. Vat. And fitting. Absolute bargain and chuffed to bits! New to tregs just sold my t5 shuttle and replaced it with an 05 v6 tdi and am loving it. Cheers all, Darren.

You did well with 6 years me thinks, I wonder if its worth just changing the battery after a certain time.

The original Vartas seem to do a lot better - 6 or 7 years - than the replacement batteries.

With the Altitude single battery are we likely to see a shorter life?

Only the V10 had two and only one as used for starting the vehicle but the other was kept pretty busy on the auxiliaries.

I think life span from new will be much the same for all the Touareg variatons, whether they had 1 or 2 batteries.

I agree with NoobyT, life unlikely to differ whether 1 or 2 batteries. As per my postings above, my Varta was original to the car and dated 2003 thus was just under 10 years when I replaced it. I was therefore happy to buy another Varta.
I previously had a V10 with the 2 batteries, one of which cost £450 to change by the local Nelson (Maindealer :) ). Thanks to this Forum, I now know it is fine to change the one under the seat on a diy basis for under £100. Instructions on this thread also inform how to change the rear one too.

In case anyone with a V10 doesn't know (and I didn't until someone told me), if you find yourself with a flat starting (rear) battery on the V10, you can use the other battery (under the seat) to start the car. Turn the ignition key to the left and hold for a short while, before then turning to the right to start. I was getting battery drain, which the dealer couldn't find despite a £350 bill, and was fixed by a local electrical specialist for no charge!
