Golf mk8 / Re: DSG Gearbox oil change.
« Last post by Carlosfandango on 16 January 2026, 23:41 »Mines 4 years old, 15k miles. I can’t see it ever having the gearbox oil changed. I might ask them to do it in the next service at 5 years, I’m not as OCD as some but 80k regardless of age seems daft. Also going to get the air con service done at 5years cos I’m fed up of them asking constantly about that too
if your A/C is cold and works correctly, there is zero reason to ‘service’ it. It’s a closed system, nothing will go bad unless there is a fault with a component, the only thing you need do is use it regularly in order to circulate the PAG oil around the system, this will keep the O Rings in good condition, the only thing that may at some distant point benefit from replacement is the receiver drier, but this will not be done during a ‘service’, they will simply remove the gas, VAC down the system, and then refill with gas and a little oil, they can even use your recovered gas in the recharge as it never goes bad unless there has been contamination from a leak or part failure, on your car at your mileage and age this is very unlikely, if it works right, then it is right.
