Battery replacement for 2009 Tdi

Hi guys, well after 10 years the battery in my Treg is dying and a replacement is needed. I will probably swap it myself but just don't know which make or model is best. Any advice would be appreciated. Thanks.

Hi Tura, easy enough to swap battery over yourself, check to find a DIY on the forum.

The original Battery is:
VARTA 95AH CCA760 VW p/n 1J0 915 105 AH Dimensions: 353x175x195

These batteries will fit so up to you which one suits your needs best, just make sure sizewise it is a DIN95 / DIN92LMF / H3 / / S4 or G14 so it fits.

Some meeting criteria above:

Bosch S5 574 035 74AH CCA680
Century Batteries DIN92LMF CCA730
Federal MF DIN95 CCA900 100AH (from Battery World) Varta 595901 (G14) 850cca
Varta 600402 (H3) 830cca/100Ah
Century DIN92LMF 735cca Bosh S4 (6003 Alco 60038 (DIN92LMF) 800cca

Here is battery swap procedure:


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:


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.

If you wish, you can buy the longer battery cable that was used in the V10. That will allow you to go up one battery size.

This is purely a optional upgrade that allows you to use either the 95Ah battery or the larger 110Ah V10 battery.
