Hi. Hope someone can help me. Recently purchased a Superb 2015 2.0 4x4 TDI mk3. I am getting avg 22 MPG. I have taken the car to two different garage and the first found one issue with glow plug sensor. Fitted a new one and did a major service. Still no improvement. Moved from a passat so driving didnt change much. Both garage cant find any fault but doing guess work. Anyone facing similar issue?

Mpg is affected by a lot more than just the engine, driving style can play a massive part too 

 

Run us through what a weeks worth of driving looks like for you.

Welcome.

Was the Passat a TDI?

 

?

What was done at a Major Service?  How much did that cost?

Was it more than an OIl & Filter, pollen filter, air filter & look see?   Was it the Cam Belt, the Haldex, the brakes serviced, the fuel filter replaced.

 

Help people here with their guesswork.

An Avarage of 22 mpg must mean you are sometimes getting only 10-15 mpg.

?

Is it 220 miles you could go if you were using 45 litres of diesel doing a brim to brim?

Are you aware of the cars doing lots of regens?

 

?

How many miles has the car done.

When you have brimmed it to know how many miles you get per litre (Or Imperial gallon)  how far are you driving it from each cold start?

Mine's a FWD so it'll be slightly better consumption and I'm currently showing 56 mpg after a 1,600 mile journey, but pottering around my hometown of Brecon in winter when the engine doesn't get warm it'll be about 20 mpg, so as ApertureS says more information is needed.

I have a 2018 2.0 TDI 190 (adblue) 4x4 DSG7

I own the car for 7k miles and it does 42 mpg

 

 

 

 

Firstly, welcome to Briskoda. You’ll find this is a great resource with a nice bunch of members. 

Secondly, that’s a very poor MPG for any Superb, let alone a diesel (I get 26-28mpg on a 2.5 mile commute!), unless you’re a “flat-to-the-floor” in every gear driver, so….

Thirdly, get someone close by to you, to do a VCDS scan to see if it’s holding any error codes - list of owners who’ll be happy to help is here; hopefully that may help pinpoint any significant problems.

Finally, when and where did you buy the car? Does it have a warranty of any kind?
