DSG oil change

[Lacer]

Apologies but have searched the forum but can't find a clear guide of the process. My uncle owns his own garage but has never done a dsg oil change before so has asked me to find out some information. But the internet doesn't come up with any clear info on the altea.

Can anyone help me out with what the process is? how long it takes? how much oil required? location of filters & where the oil goes in?

All I know is oil needs to go under pressure? what does this look like? do you need a special tool?

If anyone could help me on this it would be much appreciated as the dealer wasn't much help.

Thanks in advance.

DSG oil change is quite complicated.

[from memory here]...

Depending on the type of gearbox there are one or two drain plugs. Remove one and drain the oil. Remove the second one and drain the rest of the oil. Remove the filter (sited on top of the gearbox) and replace with new. Refit one of the drain plugs. Fit a special oil fill tool to the second drain port and fill with oil til it overflows, then stop. Leave the drain port open and connect either a dealers diagnostic system or VCDS to the cars OBD port. Access some measuring blocks and start the engine. Run until the gearbox oil hits specific temperature, during which time excess oil will be discharged through the still open drain port. Once the gearbox oil hits critical temperature, switch off the engine and reconnect the drain plug.

This gives the correct fill level at running temperature and must be done to ensure that the oil is nether underfilled or overfilled. Both are bad for the gearbox.

As said, this is not Gospel, just an overview of what the procedure is. Oil and filter could be neck end of £100 or so, so if a main dealer can be badgered to do it for a couple of hundred all in, that would be the way for me.

Just one oil drain on cars made after 2005.
There's also a sneaky top-fill method. Search for it online.

This makes it a lot easier as it removes the need to get the engine to a certain temp and basically over-fill it, and then let it sort itself out through the drain plug.

Basically you measure what's come out, and you put the same back in. (about 4.5-5 liters).

The method Viking describes is the official SEAT/VW/Skoda method...and is probably best. But it requires VCDS/Vagcom and a VAS6262 fitting to fill the oil in from the drain plug (can get off ebay).

Good luck
