When trip odometer reads 0.0, keep pressing the button and insert the key into the ignition. Turn the ignition to on (not start). The display will read "Service Now". Release the trip odometer reset button and press the "m" button to the bottom left of the tach. The "Service Now" will disappear. You can confirm the re-set by removing the key from the ignition and holding the trip odometer reset button for 3-5 seconds. The MFD will display the miles until next service.

Went out to my TDI today and it would not fire. It was cold last night but it has been colder before. I just filled up on Friday and put antigel in the tank yesterday morning, so I don't think the fuel has gelled over. Can anyone give me some tests to try? I noticed that occasionally there is a drip by the fuel pump. I'm thinking maybe with this leak I'm getting an air lock?

Replying to: swalsh19 (Jan 11, 2009 7:31 pm) You did not say what year your TDI is so we do not know which engine you have. HOWEVER... failure to start most often points to one or more burned-out glowplugs. Depending on the year of your TDI... some of the GPs may not be "monitored". Newer TDIs actually run diagnostics on all the GPs each time you start the engine. Hard-starting usually points to your IQ (Injection Quality) being set to improper value. A combonation of IQ being wrong and some burned-out GPs would really be hard to start in cold temps. Keep im mind that IQ can 'drift' out of spec as the TB (TimingBelt) wears and should be checked at the same intervals as the TB.

Replying to: swalsh19 (Jan 11, 2009 7:44 pm) There is also possibility of GP harness or GP relay issues. For more details...you may also wish to read GlowPlugs 101 (All 9 pages of it.) If you do end up pulling them, be VERY careful. Especially if they have never been out before. Make certain that the engine is STONE COLD. You may have to 'work' them out a little at a time, spray with some lube and re-tighten every 1/2 turn to keep from galling the threads in the aluminum head. As you install each one, apply thin layer of antiseeze compound designed for aluminum. |
