Hello everyone!! I hava a Skoda Octavia mk3 5e 2013 1.6 diesel DSG and after I changed my oil and filters and transmission fluid at my mechanic the car has more fuel consumption. I mean from 5.5 l /100km it went to 8.5 l/100km. He took the battery out so he would have more space to fill from above the transmission fluid. Did that mess anything up?? There are no indicator lights going on on my dash. Any ideas? Thank you all for your time.

Are you getting the readings from the display in the car or  taking your own readings by filling the tank to the top, zero the trip counter, drive till nearly empty and then refill to the top?. Calculate the consumption that way.

Is this higher fuel consumption showing on how the cars actual range has dropped from full tanks and not just the Maxidot showing this or the average fuel consumption.

ie, are you having to by fuel more often, and how long had you had the car before the service and how many km done since the service.

?

Has the Air Filter been changed?

 

 

The DQ200 DSG did not need a (preventative) oil change. 

 There are 2 oils for this 7 speed twin dry clutch DSG and they do not have a Service Schedule for oil changes.

 

People might well change the oil if they want to, but really need to know what they are doing.

Oil for the box & oil for the MCU.  (Wet Clutch DSG's are just 1 oil that does both functions.)

I filled it up and now I am looking how many km it will do. Normally it does 550 to 600 before it goes to red. This time I am worried it will do 400 450 the mechanic said he did a reset. On the display it says that my fuel is good for 520 km distance when I filled it 

He will have done a reset as you say, and had the car ticking over going no place and that used fuel.

 

So you actually do not know yet if it is getting worse fuel consumption.

 

?

Why did you have the DSG oil changed?

I got this car December 2013. It has 264000 km . First hand. From the consumption display I see 8.5 /100 and I was used into seeing 5.5 6.2 . Its a dry clutch. I didn't change the oil of the mechatronics. I just change the 1.7 or 1.9 oil for the gearbox. Underneath the battery. Since the battery was out for an hour or more i am thinking maybe it lost the memory? 4 years ago I had a software update that Skoda gave for my car. Is it possible to lose the update? 

 

The software update '34H5' on many DQ200 DSG's from 2013-2015 was started in 2017 and you should be OK with that still being there.

(This was after the World Wide Recall on 2013 on the 2009-2012 cars which was just a a Service Campaign in Europe, changing oil from Synthetic to mineral & a software update. 34F7.)

 

The DSG can reset and then settle to your driving style, as will the Maxidot and the fuel consumption once you have got back to your usual driving should then recognise the Average Consumption and calculate again when you fill up what your fuel use was in the short period before going to the pump.

Yes, right now. That will recalculate itself over the next 100km or so according to your driving rather than your mechanic's plus idle time.
