VW Jetta 2004 low MPG issue...HELP?...  Hey Folks,

Hoping someone can point me in the right direction. I have a Jetta GL 2004 with around 90k on it. I;m getting really low MPG. Half the tank is gone and I'd be getting only around a 100 Miles (in the City). I had the O2 Sensor's replaced but still getting same. Any advice on how to up my MPG, any ideas what the issue could be??
Its a 2.0 Litre, 4 Cylinder, GL Jetta 2004

Answers
1)   If you've got the 2.0 8v engine, there's probably no helping it, unless there's an active check engine light or a stored trouble code.

If it's got the 1.8t motor, there may be a fault with the turbocharger. - Felix C

2)   It sounds silly, but are your tires (or tyres) properly inflated? If they're not, that can affect your mileage quite a lot.

My 2000 New Beetle (1.8 Turbo) gets about 22 mpg around town, but nearly 30 on the road. - Bryce

3)   you could have a faulty gauge, other possibilities are a blocked air filter, blocked fuel filter , faulty temperature sender, faulty injection pressure valve, faulty Mass air sensor(very common on high mileage jettas), wrong spark plugs , they changed the recommended plug which doesn't show up in auto store charts - Harley Drive

4)   Check and/or replace your air filter.

This is a commonly overlooked item and is essential to good fuel mileage.

A blocked or restricted air filter causes the engine to work harder, and allows much less air into combustion causing poor fuel mileage. Also check the air box for restrictions and/or debris that could be present.

It is possible it has never been changed. Like I said it is commonly overlooked. - nywholesale

Question 2
What's wrong with brake lights on my 2004 VW Polo?...  Brake lights won't come on until I push hard on brake pedal all the way down. I know they should light up even with the slightest pressure on pedal. Could it be a weary sensor, or a loose tension?

Answers
1)   Your brake light switch is either going bad or out of adjustment. - nywholesale

2)   Have a look under the brake pedal, there Should be a small switch. these can sometimes move off centre or just become faulty. Hopefully a quick look should solve everything. If not the have a fiddle as they're usually adjustable

good luck.

Shane.

P.s. I don't advise removing any connectors as this may put a light on the dash! - Shane Hall

3)   VW's usually have a rather crappy telescopic brake light switch mounted above the brake pedal, which sometimes needs to be adjusted. Once it starts playing up though, keep an eye on it or just replace it now, as they aren't expensive and will only get worse. The other possibility is the switch being a pressure switch on the master cylinder, but I'm almost certain your car will have the switch on the brake pedal. If it is on the master cylinder, than make sure there is enough fluid in the reservoir, and that it's been changed since the car was new as it should be changed every 4 years at most. - Neil B

4)   Check the brake light switch. This is probably the problem, actually it can make your brake lights stay on, too - megan

Question 3
Honda or vw??????????...  is honda or vw better???

Answers
1)   it really depends on what you are looking for. a volkswagen is usually more costly to repair and more difficult to repair yourself. hondas are fairly cheap and simple. there are a whole bunch of people that swear by each kind of car. i am a mechanic and i'd go for a honda over a vw. but then again that's just my preference. you also need to take into account creature comforts and features. - peterson

2)   VW! - Dsvfshj Hjvsdfhj

3)   VW! - Jacque M

4)   If you don't know a good independent VW mechanic, then you might consider the Honda, because VW dealers tend to be expensive.
If you want to save money in the long run, and want to keep the car over 5 years, then get the VW, because it will last almost twice as long as the Honda. - Motorhead

Question 4
How much does a 2008 volkswagon r32 clutch cost?......?...  How much does a vw r32 clutch cost? It is a dual clutch. I just bought it certified preowned from a dealership. It feels like automatic and sport mode is slipping but not manual mode. I only had it for 3 days.

Answers
1)   take it back to the dealership and demand your money back. - Treva

2)   Take it back to the dealership where you bought it from, and they might be nice and teach you have to drive. If it's from a VW dealership then they will have tested it thoroughly, and I'm not sure you have a multi-plate clutch, either! - Neil B

3)   If you bought the car CPO, why do you care how much it costs? The answer is a lot of money, so take it back to the dealership and have it checked out and replaced if there's an issue.

The DSG is not a serviceable unit by any VW dealership besides the required fluid and filter changes every 40k. Anything more involved results in a replacement with a new transmission. - gti_4cefed4

What is the difference between the 2011 Jetta SEL and the 2012 GLI?...  I have been test driving a Jetta SEL and saw that the 2012 is coming out soon and it keeps mentioning the GLI and I have no clue what that means. Do they make a GLI now or what is that. Can someone explain?

Answers
1)   looks like vw has succeeded at appealing to toyota and honda buyers with their cheap new jetta's like they planned...i mean..you don't know what a gli is? it's the higher performance version of the jetta like the gti to the golf. - Dsvfshj Hjvsdfhj

2)   The 2011 comes with EMP horn. - Jacque M

3)   The GLI is the performance Jetta, much like the GTI is the performance Golf. It comes with a 2.0 turbo engine producing around 200bhp.
