Hi i have a mk 4 astra gsi turbo on a 53 plate and have removed the driveshaft to replace a cv joint boot and now want to drain and refill the gearbox with new oil.
I have found what i think is the fill level bolt on the back of the gearbox between the two driveshafts and about level with the tops of them, this bolt looks very similar to the sump plug bolt.
Can anyone tell me where these bolts are and what they look like...
Thanks.
