Battery, differentials, transfer case & gearbox fluids, coolant. (hopefully fuel filter is also covered by your "filters" mentioned)

 

Thanks for your reply.

I have of course been replacing the oil, air and cabin filters. The oil filter when changing the oil and the others at least as often as stated by VW.

Is the transfer case fluid different than the gearbox fluid in this case?

When you mention the battery, is it suggested to replace it even if it works perfectly?

Thanks again for your help,
Longoria.

 

I said FUEL FILTER.... DIESEL FILTER... not oil.
Yes, the transfer case is different than the transmission.
Batteries don't last for ever. Depending on climate and use pattern, they can fail as early as 4-5 years. If yours is the original one, I'd be impressed.... but I'd also be ready to be left stranded any moment now.
If you have VCDS, you can look into its details.

 

I misread, yes, the fuel filter has been replaced, but I think I will replace it again.

Indeed, my battery is 10 full years old and still going strong. But I guess it is better to do a preventing replacement, rather than risking the need of being towed.

Then I am looking at:

• Oil.
• Oil, fuel, air and cabin filters.
• Differentials, transfer case, gearbox and power steering fluids.
• Battery.

I would include power steering fluid. As every fluid, its not lifetime.

 

Accessory belt, its tensioner and idler rollers.

 

I am adding this:

I may replace the front brake pads even though they are not done yet... Do you always wait till you get the signal to replace them?

Here's my battery post for some reading material if it interests you.... should give you some insight

2014 TDI starter battery replacement - probably...

Well, I've had my '14 since '18, and although it's never not started for me, I did notice it cranking slowly during our winters up here, have had a bunch of codes for low voltage events over the years, have had locks and aux heater codes, and other low voltage hints such as the EMS stepping in...

I'm not... I just read my service manuals

You need to check at a dealership for your actual VIN for the correct parts for your vehicle.... depending on market and options, these can differ.

 

Thanks all for your help, I have completed the 10 year maintenance.

This is what I have done:

• Oil.
• Oil, fuel, air and cabin filters.
• Differentials, transfer case, brakes and power steering fluids.
• Battery (95A instead of 105A, but I will flag it for changing in five years).
• Accessory belt, tensioners and rollers.
• Front brakepads.
• Front and back Wiper blades.
• Deep cleaning (deepest ever) including rubber lubrication, leather conditioning, waxing, etc. (I use to apply ceramic coating every two years but it was not possible this time).

I must say that the battery was 10+ years old and still running. My mechanic read some small issues in the battery but nothing major. I replaced it anyway.

My rotors are also the original ones, and I am planning to keep them from some time since but my mechanic and me see them as showing little signs of wear.

In 115.000km I have replaced the brakepads once. Now the front ones for the second time even though the indicators did not show the need, but it is a cheap replace once the car is at the workshop.

I know that 10 years and 115,000km of battery and rotors is more than what most people expect... Why can this be? Maybe my driving style has low impact on the components?

For the future (1-2 years) I leave:

• Gearbox fluid and filter with new joint and screws.
• Front and back rotors and brakepads.
• Ceramic coating.

I will probably do these things with the next oil change.

You have helped me a lot, I would like help with the gearbox fluid change, I have already got some help from here:

Touareg 7P 8 speed transmission (NAC) oil change

Hi All I have been trying to find some information on DIY transmission oil change but have not seen any for the 8 speed Aisin transmission. Mine is 2012 7P 3.0L diesel (engine CRCA) with NAC transmission. Can someone please help. I am after the following specific information: 1) transmission...

VW has outrageous prices for this fluid. It makes no sense. I would like to find who produces the G 055 540 A2 fluid to purchase the OEM one instead.

About the Transmission Strainer and Sump gasket, I see there are kits sold by aftermarket manufacturers. Are those reliable?

Any suggestions at all?

Longoria.

You have other options... use the search function... it's been discussed many, many times....
Here's an example

2013 Touareg TDI transmission oil

I need to fill my transmission back up after hitting a peice of steel on the highway. Put a hole in my trans oil cooler. VW wants 80 dollars a litre for ATF. Is there an alternative that will work the same or is it risky using aftermarket ATF with these tregs? Thanks

Believe it or not I did search, but I could not find one that was really clear (I found for instance the one I shared).

Your reference is much more clear.

Thanks.
