I decided today to give my 9-5 Aero a proper service as I have had it for 5 months.
It was serviced by a VW dealer a month before I bought it and has been OK apart from the slightly higher fuel consumption than my last Aero.
The oil change went OK apart from a very tight sump plug.
I decided to replace the gearbox oil for 2 reasons. Since I have had the car I have noticed the gearbox was always damp with gearbox oil and secondly on my last car the gear change improved with new fluid.
I undid the gearbox drain plug and was surprised to find the fluid was quite thin,cherry red and also there was a lot of gearbox oil. I did not measure it exactly but it was a lot more than the 2 litres I was expecting. My catch can hold 5 litres and it was nearly full.
I can only presume the oil must have been replaced in the past and who ever did it looked at the automatic specification and filled it with the 3.8 litres that it specifies.
I have just been for a test drive and funny enough the gear change is a lot crisper and the car feels a lot quicker but no wonder with all the all in the gearbox.
It will be interesting to see if the fuel consumption improves.
I have cleaned the outside of the gearbox with solvent so hopefully I will have a dry gearbox from now on.
