I had attributed my initial poor performance and low mpg to the use of Shell V-power (which is less potent, but cleaner) for the first 2.5 tanks of fuel. I had seen a small improvement when moving to standard Esso, but not much. Just hoping that I didn’t have an irreversibly poor running in period because of the V-power, although I don’t think that is the case because others here are seeing similar mpg.
It does confuse the hell out of me why DSGers (including my dad) are generally seeing much better mpg. I’m thinking that the DSG box’s management of gear changes is more in tune with the engine than the gear change prompt software on the manual. It sometimes makes no sense at all. Sometimes it’ll happily take being sat at 42mph in 6th, but drop a few mph and it wants you to drop to 5th (fair enough), but as soon as you’re in 5th, it wants 4th, then 3rd. So you end up from 6th at 42mph to the car wanting to be in 3rd at 36mph, move back up to 42mph and it wants 6th again, which suggests to me that it doesn’t want a higher engine speed for a regen. Some of the time (lately) I have given up taking the gear change indicator as gospel and ignore the car wanting to be sat at 36mph in 3rd and leave it in 4th or 5th instead.
My dad hammers his DSG and still gets 51 indicated/48 actual mpg.
If I could buy again, I’d buy a GTI and expect 35mpg.
