I've got a 2002 TDI Golf that has bee getting about 50mpg up until my last tank of gas where it dropped to the high 20's. Can anybody give a guess as to what's...
Maybe it was the gas? :) Couldn't resist being the first to make that smart a$$ comment. Has your driving changed recently? Possibly a lot more city driving...
How many miles? Last air and fuel filter change? Last timing belt change? Dragging brake? Fuel leak? Slipping clutch? Shawn ... Shawn Upton, KB1CKT ...
The only thing different is driving in snow and ice for the past 2 weeks. That shouldn't make a difference should it? ... that smart a$$ comment. ... than...
In the snow and ice, have you been spinning the wheels a lot? Does it feel like you've lost power? More smoke than usual (Black or White smoke?)? Nathan '02...
I'd say that the only thing that would explain a 40% drop in mileage would be a fuel leak or a computational error. Are you sure you didn't get shortchanged at...
I'm no expert, but ... The TDI's exhaust gas recirculation system re-routes exhaust gases (under certain conditions) back into the intake manifold, allowing...
Sorry I missed the original question. John Ewing's answer is, IMO, pretty balanced. There is a plethora of strong opinion in the biodiesel world and certain...
Another couple of ideas: what are the chances of moisture being frozen in your air filter? In cold weather, it can really reduce the airflow. Reduced...
I'd like to detail some of the results of my fiddlings over the last 15,000 miles following a thorough scrapping of my intake manifold. It's generally assumed...
If you didn't clean your intercooler, I wouldn't be surprised if you were still seeing oil residue coming upstream from where it had accumulated in the...
Interesting observations, Roger. Just so you know, diesel autos in California are not required to undergo a smog test. In fact, you currently can't buy a NEW...
It's true that you can't get a new TDI in California, but there's one weird exception: the Touareg V10 TDI. Go figure. Cheers Keith. ... [Non-text portions of...
I do find oil in the joints when I pull the hoses off for inspection. I figured it may have been from possible residual accumulation in the intercooler being...
Thanks everyone for your suggestions. I tried a bottle of Gumout and my Golf seems back on track. I've heard that the diesel around here has a very high sulfur...
New one on me; have not heard of LSD affecting the fuel guage. Only that it promotes soot and that the soot combines with CCV vapors to clog up intakes. ...
Mess with the fuel gauge how? My FG was reading 1/4 tank high on cool mornings, then normalizing after maybe 40 minutes driving. I figured gunk was changing...
Shawn, Why is it that I think I have seen that callsign before. Maybe on the Elecraft or QRP-L forums? I agree with your assessment of Gumout, may clean the ...
I have a 2004 Jetta tdi. On my console, the light that lights up the temperature, fan speed, etc. is not working. Is this an easy fix? A fuse? Thanks, Jeff...
I just went to All-Data and checked the fuel sender unit. I have a subscription there for my NB. They show the part number as 1J0919673G and the price being...
I know they have to make changes to the wiring when they convert a vehicle from gasoline to run on E-85. Something about increased corrosion due to the E-85....
Hmm ... as you can see from my sig block, I do home brewed biodiesel. But (as you say), I would have expected that the BD TDI community (which is large) would...
I too brew and use my own biodiesel, usually run 80-100% depending upon my time to make the stuff. I haven't had issues with the fuel tank sender, however, I...
I had to take my fuel sender out to drill out the check valve on the intake of the plastic sender. In really cold weather it was causing fuel blockages and...
... I wondered what that arrow was for. Mine points to about 4:30 which is what it had when I first looked at it. This is so simple, I just have to try it....
I have read a lot of posts on how to deal with MAF sensors, but it usually relates to the electrical function of the sensor. My sensor failed at about 61,000...
Got my car (02 Golf GLS TDI) back from bodywork on the rear end and have a few problems that it will have to go back for. One is that the fuel filler door...
... On my 05, I found that if you have someone pull or pry on the door while someone else hits the release button, it popped open. (I didn't have a piece...
