#5867 of 6629 2001 VW Jetta wont start
Nov 20, 2008 (12:50 pm)
I have a 2001 VW Jetta GL, standard 2.0. Car began to be hard to start, then died. Repair shop told me it was fuel system rerelated. I replaced fuel filter, car started, ran fine for a few days then died again. Replaced fuel pump, and fuel pump relay, and fuel pressure regulator, still will not start. Engine cranks, there is spark, fuel is reaching fuel rail, but will not start. I am at wits end, this car has been such a constant problem, any help would be great, thanks.

Again try to see if the Ignition Coil is bad. Well known item to fail.
Better to use a part from VW parts dept. Since after market ones like from Autozone (where I work) seem to not be up to specs to handle the load a VW puts on the part.

have a '94 just got it (comuter car) very clean - the dang alarm is sounding when the batt is connected
prior owner lost the master key and I had one made (not by VW) the barrel on the drivers door is broken but still cant silence the alarm even when actuating the door lock with a screwdriver!!
and the key will not actuate the passenger side door! it DOES operate the ignition but with the alarm engaged, the ignition is locked out -- any clues?? or will a new master key being made fix this? thanks in advance for any suggestions!
Did you get the new master key?
This is the first thing you should do so you have the right part.
After that you should make sure you have the code for the radio to reset the alarm.
Get it from the dealer and pay a hefty price.
Otherwise put an after market radio in, but watch the extra wire that may be there to tell when oil changes need to be made. It might interfere with the OBDII getting codes at a later time. It may ned to be cut and covered.
#5870 of 6629 long term VW ownership.

Yes - my daughters each still have their 2001 Golf / NewBeetle. Both vehicles have needed brakes/rotors... but that is not unexpected.
My one daughter really drives her car hard (the rough roads dont help) and her 2001 Gulf has needed some suspension work (springs and various rubber bushings) Reciently the flexpipe between engine and cat broke at 100,0010 miles. Although the warantee is really for 100,000 miles, the dealership covered all except $23.
The latch on the armrest cover has broken one every single VW we own.... fortunately, replacment latch is about $10 and easy to replace in the driveway.
This past summer with my 2003 Jetta, both front fenders started to rust. VW honored their 12Year/UnlimitedMileage corrosion warantee and replaced both front fenders.
Overall, I know if any of us were looking for another car we would, without question, look for another VW.

i read what you have replaced an still no fuel to fuel rack. reverse engineer. disconnect fuel line from fuel rack getting gas? if not keep going back until you get gas and then replace one part at a time till gas gets to fuel rack. if get gas at point where fuel line goes into the fuel rack then it could be the computer or injectors
#5872 of 6629 Replacing thermostat in 2001 2.0L Jetta
Nov 22, 2008 (2:57 pm)
My son's Jetta with 93K miles was acting up by temp gage going up and over heating. The fans were running, the coolant tank was at full level. I decided to change the thermostat and the coolant at the same time.
It is amazing the VW dealer wanted $30 for a gallon of coolant. I bought Mercedes coolant from MB dealer for $18/gal for my E430. I don't know how VW justifies charging $30 for coolant. I ended up buying $9/gal Prestone that you can mix and use for all car brands. I question these car manufacturers coming up with their own coolant and ripping off their customers.
Removing the thermostat housing was a nightmare. The lower bolt has the alternator right in front of it with no room to reach it, it took me hours with tools I had to rig somehthing up to get to it .
I think VW's 4 cylinders are much more complicated to ge to simple maintenance items than some V-6 or V-8 engines. I have never seen intake manifold blocking spark plug access on a four cylider engine before.

To address the cars' issues, it might be better to find someone with a VAG.com who can hook it up and trouble shoot or bring it to an independent VW vendor or in the worst case, bring it to the VW dealer. It will be throwing codes.
Actually 30 for a gal is not bad given most of the other than dealer vendors sell a gal 25 per.
This might not apply to the 2.0 engine, but the oem owners manual on the TDI engine specifies and requires G12. It is truly a lifetime coolant; unless of course, you have (a source of) contamination issues( head gasket leak etc) .
I only replaced a portion of of my G12 (way less than a bottle of 1.5L, as you dilute 70% G12 + 30 % distilled water) when I had the 100k miles interval- TB/WP changed; as the container used for the G12 anti freeze catch proceedure was used for other peoples G12. (didn't want to contaminate mine with others and vice versa) If I had brought my own catch container, I would have reused MY old G12. So basically I made the decision to top it ( the proper dilution rate).
So if the 2.0 engine oem owners manual specifies G12 it is indeed a HUGE mistake to NOT use it. So if you did use other than the recommended anti freeze you probably have contaminated the existing recommended antifreeze.
As an after thought, the time to question these things is when you do NOT own it.

I don't know how VW justifies charging $30 for coolant. I ended up buying $9/gal Prestone that you can mix and use for all car brands.
I don't understand why you would want to risk using the wrong coolant in order to save a lousy $21. I'd don't think I would trust Prestone to know what is safe and best for a VW engine or what is safe to mix with G12.
In addition, if there was no actual need to change the coolant in the first place, how is VW ripping you off? Instead by installing G12 in their new cars, they eliminate the need to pay for routine coolant changes.

My issue is every body having unique coolant for their engine...Exactly what is so unique about VW engine????? It is like saying use only VW oil filter. Over some 35 years of owning some 25 different cars/trucks/vans/SUVs never ever used manufacturer oil filter or coolant with the exception of the MB coolant. I figured $18 for MB vs. $11 for Prestone, I went with MB.
I have had ZERO issues with coolant or engines. Are you still insisting on VW coolant? I have issue with them charging $30. What is in it that costs $30/gallon?
VW's plastic water pump impeller breaks whether you have $30 or $9 coolant. I am not cheap but I do have problem with rip off prices.

The G12 antigreeze is a LIFETIME item that never has to be changed. It is a HOAT (Hybred Organic Acid Technology) formula. You should have SAVED what came out and put it back into the engine.
Mixing ANYTHING else with HOAT has been known to cause a gell to form and may clog the small passagaways of the cooling system. You are gambling with making the engine into a boat-anchor by saving a few bucks.
BTW: You can get G12 antifreeze from any diecent autoparts store. Do you really think that VW *makes* antifreeze..... I hope not.
I use Pentosin which is the same company that makes the VW-labelled stuff.
