I got a sudden drastic drop of MPG in the past 2 days. The car does not give more than 15 MPG in normal city drive while it used to be between 24 and 26. There are no fault codes. The air filter is clean, spark plugs were changed 2 years ago and coils are new. MAF senor was changed last year...

Hi does anyone know if the lambda sensor affects the mpg readout. My mpg readout is all over the place ticking over at 12mpg but accelerating at 27mpg and everything in between. When I lift of accelerator completely still reads 53mpg or 30mpg just depends how it feels cheers Sent from my...

Hello everyone. If this post immediately makes you think of other post results please link them here. I was talking to a friend of mine on the way back from work about increased performance to ultimately increase mpg in our v6's. As we talked I was reminded of a magazine that ran dyno...

Hey guys!! Ya gotta love all these automotive forums, they help out when the "cheater dealers" can't. All the small stuff that keeps these cars rollin in style. I have a duramax and a cummings diesel so I hit them up for advice, and the Taurus/sable site too. I've had my 4matic for a couple of...

I noticed my MPG drops quite a bit when my climatronic unit is turned on regardless of if it is heat or air conditioning. Is there a part that may be malfunctioning that is causing this, or is it just how it is supposed to be? Other than the occasional P0421 that comes and then goes for a while...

So, a European car in the USA, shows MPG etc. Is that in miles per US gallon or per Imperial gallons? If capacity is 62 litres, then it's 13.63 UK (Imperial) Gallons and 16.38 US (Gallons). Fuel Economy site shows combined mpg of 20 (combined) and 25 (highway) so i take it that is US mpg...

I just bought used 2014 vw passat 2.5l with 60k miles. So far I have been getting pretty bad fuel mileage, well at least in my opinion. I have been averaging about 24 mpg according to the MFD, most of my driving is on the hwy to get to school. for ex today i had a little over 1/4 of gas so I...

I looked through many forums but couldn't find my specific problem. I never got too good MPG since shortly after I purchased the car (99 Passat 1.8T AEB), however after just changing the oil, valve cover gasket, spark plugs, control arms and springs, the MPG is still just as bad / worse. What...

18 vs 53 MPG. On the left you will see the city MPG of the Passat. On the right you will see the city MPG of the Prius. I am now a confirmed hyper-miler. Know anybody who needs a set of B5 Bentley manuals?

hey guys i have a 2005 Passat 1.8T 4MOTION and it has 146000KM on it. Lately i have been taking a smell of engine oil burning when i break, it does not happen often. My Valve cover gasket was changed during the summer. also i have notice a small oil wet spot in the back of the engine. i was...

A few months ago I purchased a 2007 Passat B6 2.0t FSI with about 140k on the odometer. I love driving the car and love all the amenities that come with it. The only problem that I have had, is the gas mileage is terrible. I have been driving it for the past 3 months, probably around 1500 miles...

Ok so I've read just about every thread here regarding mpg fuel selection etc etc. My situation: My 2001 B5.5 was diagnosed with a bad head (138K miles). We decided to change it with newer engine instead of rebuild the one I have. new/ used engine (had 62k on it) and clutch and (comfort control...

I just had my fuel filter and air filter replaced so now my mpg is actually going up in general, but it is still not making sense that I was getting better mpg driving at speeds from 25-50 in my town than 70-77 on the parkway without stopping. I'm absolutely stumped. I use cruise control when I...

I now have 13k+ on my '15 Passat TDI and just hit 48.7mpgs on this last tank per my fulley records. That's my best tank. I Always hear that TDI mpgs get better as time goes. How many miles until I won't see gains on MPG?

Got brand new 2015 Passat 1.8T... After first 600 miles my average MPG is 15.6 MPG. What gives? Any ideas, suggestions?? I'm conservative driver, with my previous vehicle I was averaging 20MPG (labeled 21MPG). Quick note: 100% of my miles are city. Any help GREATLY appreciated!

I'm losing my 2006 passat 3.6 4motion in a divorce, car is in my wife's name. I'm not going to pay her for the car. Just wondering what MPG everyone is getting in their 4motion? Andrew

Lately ive been getting horrible gas mileage. I get somewhere between 200-250 miles per tank. I recently did plugs. They were soaked in oil so I know I will have to do the valve cover gasket asap. The only mods are cat back exhaust and cold air intake. It has also been throwing the p0011 code...

Hi. I was wondering if anyone could help. On the dash, I usually have the remaining distance in miles for the fuel I have in the tank. It was find this morning. When I got in the car this afternoon it had changed to MPG. I have no idea why it has done this, but I would like to change it back to...

Since the recent purchase of my 2005 STi, there is no reason for me to drive my 1.8t passat hard anymore. That being said, I am trying to drive more fuel efficiently, I still find it hard to get much over 30mpg on average, a lot of highway driving, not much stop and go. All that I have done...
