| Prior to my car accident, I did not experience any issues with my car. A almost month after the accident, my coolant light came on. I couldn't even open the hood after the accident. I later got it to open and realized that the coolant tank was empty. Then I thought to myself I haven't heard my fans turn on in a while. Sure enough, the fans weren't turning on. I got my crappy insurance company to come pick up the vehicle and take it to one of the "approved" shops. A month later I pick up my car. I didn't like how they fixed my body kit, but I could deal with that sorta. 50miles down the road, my coolant light came back on. I looked and it was BONE dry. The shop towed my car back and for the first time a mechanic check my car. They call me back saying that there is a pin hole in some hose that has allowed air to get in. They then said it wasn't accident related and that I had to pay to the diagnosis. Is this possible for a pin whole is a hose to cause my fans not to turn on and my coolant to leak out at the point of impact? I just know that my car was in perfect working order prior to the accident, no lights indicating problems and regular check ups. Can someone help me understand please... | |

Replying to: freeantelope (Nov 03, 2008 11:28 am) First of all, that thing is called the VNT actuator. The turbocharger is a VNT (Variable Nozzle Turbocharger) and the adjustment on the 'shaft' of the VNT actuator is tuned at the factory. Altering it can have devastating effects on your engine. (like overboost!) the code P1550 you are getting is pointing directly at that as the problem ( http://wiki.ross-tech.com/index.php/17958/P1550/005456 ) Essentually, code P1550 is telling you that the computer senses a problem with the VNT actuator or its control piping. Also check your N75 valve. Here is a website that has excellent photos of the inner-workings of your VNT... pay close attention to the very last moving photo which shows how the VNT vanes move.

Replying to: bpeebles (Nov 10, 2008 4:38 pm) Do you know the specs the VNT actuator should be set at for a 1999.5 TDI (new body style I think thats called MK4)? I had to replace it (it was rusted out and didn't move at all from the previous owner). Thanks for your efforts Jason

I have a 2004 Jetta GLS....recently the floor on the driver side, front and back, is soaking wet - mat included. They've been there for about 2 weeks and show no signs of drying - I do live in the Pacific NW so its wet here a lot but the floor was flooded weeks before the rain really started. I can find no leak/hole etc. explanation for it and when I took it to a service station (not the crooked, dishonest, ripoff dealership) they wouldn't even look at it because it was on the driver side and it was just water on the floor. Apparently I'm supposed to contact the Water Doc but can't seem to find such business (in Kirkland, WA). Any thoughts or suggestions or similar experiences would be greatly appreciated, a door seal possibly?? I lost my job about 8 months ago so I'd like to avoid a giant repair bill if possible (or a giant bill just to look at it and tell me its nothing). |

Replying to: freeantelope (Nov 12, 2008 4:32 am) I have even considerd driving from Vermont to see Herm for a TimingBelt change. You may consider at least calling and chatting with him about your TDI problems. You can find Herm and other TDI mechanics in this list |

Does anyone know how to slow down the oil consumption of this engine? The engine uses about a quart every 700 miles. The car has 91K miles and ir runs great. There is zero oil leak and there is no smoke out of tail pipe at any time. Is there any special product or oil to use? I have been using 5-30W name brand oil. Thanks, Joe

Replying to: jodar96 (Nov 18, 2008 4:21 am) You might want to have a cylinder leakdown test done to see what the problem is. If it's valve guides you may wish to consider getting that fixed. At a quart every 700 miles, you are starting to put stress on your catalytic converter. There's nothing in a can that cuts oil burning for more than ten minutes. You can gunk it up in there but that does more harm than good. If you are in a mild climate you can switch to a heavier oil, sure, like a 10W-40 or 20W-50, and see if that matters. I kinda doubt it but you never know. Or you could even run a straight weight oil if you can find one that meets your engine's specifications. But that could be hell in winter. Anyway, get a cylinder leakdown test done and then at least you can end the speculation about where exactly the problem is, in the engine. |
