#2385 of 2483 no fuel flow to injector pump by soapysails Dec 14, 2007 (4:09 pm)
I had the misfortune of running over a chunk of snow/ice ! it poke ed a small hole in my fuel line. I was able to cut out and replace a 4" section, however, it won't start. This is what I have done: a. bleed lines to eng. b. checked to be sure filter can is full of fuel c. checked fuel pump fuse. when we took the lines off, turned on the key, we were unable to get fuel up from tank.. am I missing anything ! BTW, I'm 100 miles from a dealer ! help boys ..   1998 vw TDI Replies to this message: pludlow (Dec 14, 2007 5:47 pm) bpeebles (Dec 14, 2007 6:04 pm) soapysails (Dec 14, 2007 8:52 pm)

Replying to: soapysails (Dec 14, 2007 4:09 pm) Sounds like the hole was in the supply line and at one of your splice connections you have an air leak. Since the TDI is a suction pump as part of the injection pump (no electric push pump in the tank like the gas engine), any leak before the injection pump will suck air. If so you should see bubbles in the output leg of the fuel filter. You may need to fill the supply line between the filter and injection pump with fresh and absolutely clean fuel until the air in the line is gone, then reattach it to the filter. Also you could use a gravity feed from a clean jar just to get the engine running then reconnect the supply hose to the pump. Good luck - it's always the dreaded problem with diesels.

Replying to: soapysails (Dec 14, 2007 4:09 pm) To validate that the injection-pump and engine are OK... it is pretty simple to route the 2 hozes which normally go to the fuel-filter into a small container of CLEAN fuel. (put a soda bottle with CLEAN diesel in it under the hood near the fuel-filter) The engine should start and run just fine running from that container of fuel.   If that gets the engine going, then you likely have an air-leak in the system between the fuel-filter and the tank.   If engine does not run - your problem is between the fuel and the engine. (lets hope your injection-pump did not run dry and self-destruct) Replies to this message: soapysails (Dec 14, 2007 8:52 pm)

#2389 of 2483 new beetle convertible TDI by blooeyes4u2 Dec 27, 2007 (2:54 pm)
Does anyone know if these are actually built? I've done LOTS of searching and haven't found anywhere on the web where this is an option. My next question is "why not?" Growing up in the 70's I owed several beetles throughout the years. A convertible beetle with a diesel engine is my 'dream' car that I would keep until they take my license ole blooeyes!

Replying to: blooeyes4u2 (Dec 27, 2007 2:54 pm) That would be a great little car. Equipped with the DSG transmission and you have a winner. Buy a gas Beetle convertible and a regular Beetle with TDI. Then swap engines and transmissions. Sell the regular beetle with the gasser and you got your dream car.   Welcome to the Forum...
#2391 of 2483 Re: 2000 Jetta TDI - Intermittant starting problems [pruzink] by trujij Jan 23, 2008 (7:35 am)
Replying to: pruzink (Apr 04, 2007 7:04 am) Any chance you could answer a question on this subject? I have a 2002 VW Passat wagon. We lost the valet key and bought a new one from the dealer about 6 months ago. We found the old one a few days ago and stupidly tried to start the car w/it. Now even the original switchblade key won't work--nothing works. Anything I can do to get the new key we had made or the switchblade to start the car again? Thanks.

Replying to: trujij (Jan 23, 2008 7:35 am) tru j , it might start with the new-made-key if you wait a half hour and retry. (If it detected wrong-resistor-value in the original valet key, and you tried it a few times in a row, i think it might lock-out the ignition for 15 or 30 minutes. some cars do that. not sure if your VW is one such...)

#2394 of 2483 01 Golf TDI not starting fuel filter? by jshlev Mar 12, 2008 (1:41 pm)
Hi There everyone, My TDI usually is hard to start on cold mornings(no heat block yet) but just yesterday it now will not fire and run. The battery is fine and the starter seems to be doing it's job but maybe it's not getting fuel? Should I change the fuel filter to see if that is the problem? Is there a way to check to see if that is the problem. I read on a previous post about a fuel line problem and they put diesel in a can to bypass the filter? Would that be a test?
