After draining the DSG box it is necessary to fill it in an unconventional manner.

The approved method is to fill via a plug hole in the base of the transmission casing.

This in turn requires the use of specialised filling equipment and much patience and dextrorotary, not to mention the mess due to spilt oil.

Having completed the fill it is then necessary to bring the oil temperature up to an approved level and then to remove the filling adaptor plug and drain of any excess.

This procedure is both easier said than done, time consuming and very expensive when carried out in the workshop. Also the expense of the special filling tool (VAS 6262) and the use of the VAG test unit (VAS 5010) then the draining off, of excess waste oil, in order to reduce it to the correct level seems difficult to justify.

This procedure places the task outside the possibility of many home DIY owners.

It seems too simple to say that the provision of a top filling plug and a side level plug would go a long way to alleviating this problem. In this way it should be possible for VAG to accurately specify the amount of refill oil and cut down on the expensive waste.

Or am I just missing the point and making it too simple. Makes one wonder if this whole procedure was put in place for the benefit of the stealers, or am I being too sinister.

Why wouldnt they want to protect their technology assuring only trained people with correct tooling service the gearbox? Makes sense to me.

Anyhow the filling tool isnt expensive, saves on mess and stops spillages as it fits directly onto the propper bottles of oil.

Using diagnostics ensures the correct ammount of oil is put it which is critical, a level bung will only work at a set temp as the oil expands very quickly with heat so unless you know what temp it is the level may not be correct and damage the box.

I have generally be quoted £140 for this and it has to be done every 40K miles. Normally paid for by company but since it will be paid for by me from I might see if I can get some competitive quotes. Usually get done with the service so gets expensive. DSG Gearbox is Borg Warner technology I recall who would tell VAG on spec etc, presumably biult under licence by VAG in Kessler I recall. When it benefit consumption as in 1.8TSI cases suppose everything comes with pluses and minuses in one form or other ie capital cost, running cost...

Accepting what you say as one way of approaching the subject.

A level bung will function in exactly the same way as the black plastic overflow snorkel does at present.

I still can't understand why the DSG could not be filled from a top filler plug and all the temperature and drain off procedures being as it is now. The biggest difficulty seems to be getting the oil into the DSG.

I have watched a Skoda main Agent fill the DSG and I can assure you it's far from oil spillage free.

Aside from daining off a little when setting the level it should be spillage free unless your cack handed.

(also been doing them for years myself and have my own filling kit and VCDS if I need to do it away from work)

VAG auto gearboxes have used the same filling method for many years, removing the fill bung means you have to use the correct equipment and prodcedure.

Also the same filling device with a different adapter for filling the MK2 Haldex system, also developed to keep the job clean and health and safety regs on handling oil are tight and geting tighter.

Sir, I take my hat off to you.

Quite obversely you know what you are taking about on this subject, probably having changed more DSG oils than I have hot dinners. I fully accept what you are saying and only wish to say that my inquisitive mind is fully satisfied.

Thank you for your replies.

For the sake of £160 (or thereabouts depending on dealer) i would let someone trained do it.

I would rather it be done properly (or if not have some come back with the Skoda Dealer) as a new DSG box is around the £4.5k mark iirc.

The main expense with it is the oil as it takes 6L of special oil.

I had mine done recently and it is well worth doing. My car now drives totally differently. I do however think this was due to the Garage i got the car from not servicing it properly before i bought it ( i bought secondhand) as it wasn't stamped in the book and the car had done 65k miles. But as i couldn't prove it i just took my business elsewhere.

Yes I am based on Worcestershire. My works Toledo which is 6 speed DSG is going soon as I am changing jobs. It was serviced by Droitwich Garage. I will not get my 7 speed DSG for another 4 months I suppose with the biuld wait and then it will take me a year to biuld up 40K miles. I know other VAG dealers can service other VAG cars without invalidating warranty. Since the 1.8TSI will be on variable servicing suppose it will need doing around the second service 35-42K miles I guess.

Always annoyed me that all SEATs and Fabia's needed servicing every 10K when I do that amount of mileage every 3 months or so!

I'm not sure of the set up of the new seven speed on the diesels, not sure if it's an adaption of the older six speed or more lime the seven in my Ibiza. My gearbox is sealed for life with no oil or filter changes.

Im starting at a Skoda dealer in worcs very soon
