I've had 8 Mark 4 TDIs, and I've seen a good number of the little things that go wrong on more than one of them, but this one was a first. The symptom was starting it would work most of the time, but sometimes it would seem like the starter hiccuped for a fraction of a second and sometimes it...

2.5 years later update on this - Still no signal clicking - I would do it again if it lasts for years and only takes a minute!

16 month followup report on door switch spray cleaner fix Well, about 16 months have passed since I first tried wingnut's technique of using just a spray cleaner without disassembling anything. I am happy to report that on the two Mk4 Jetta's I used the spray on, the driver door switches are...

Yeah, I just looked and don't see it for sale on Google Shopping, and the only links on Google are not in North America. My can came a friend's biz off a shelf full of aerosol cans. I mentioned earlier that it seemed similar to carburetor cleaner; it smells similar. I looked at my can of...

3M Scotch 1626 - a white spirit and acetone blend. Application: Ideal for dissolving greases, oils, resins and tar everywhere on electrical equipment, switches, safety cut-outs, motors and generators. May corrode plastics. I didn't notice any problems on the factory paint I could see but...

My daughter had a great experience with Brett of Eurowerks in Columbus. Her 03 Jetta sedan broke down while visiting for the holidays 2009-2010; her brother-in-law told her that it sounded like the timing belt had slipped - end of the world. She checked out the trusted mechanics list here...

Darkhorse, I used a spray cleaner that is very aggressive on grease and grime. Closest thing I can equate to off-the-shelf products would be carburetor cleaner or maybe non-chlorinated brake cleaner. Seems to be much stronger than electrical contact cleaner at removing petroleum-based grime...

3 cent - 3 minute fix I concur (again) with wingnut's very practical solutions. Using the spray cleaner method, I have fixed several Mk4 door switches now, and they have been working fine for months. I have one improvement I can offer. In the picture showing the spray cleaner can, the latch...

8 months since using spray and air and the problem hasn't come back. I will post if it does.

I concur with TornadoRed that this this turn signal dirty contacts problem can be pretty much corrected without any disassembly of the steering column whatsoever. I would add to his "Squirting some WD40 in the general direction of the turn signal mechanism" that it is possible to spray the fluid...

Four years later update on my airbags experiences... Biggest update in past 4 years is that I've had good success with having the blown airbag control module reset by myairbags.com. Beauty of sending your module in for reset is that you can plug it in and the airbag light MIL goes off (of...

Thanks watercop. Says "diesel: now, what it should be.

5 millionths of a US gallon is how much fuel I figure is injected each time into the cylinder of a 4 stroke engine getting 50 mpg at 2000 rpm in 5th gear which is typical for a MkIV 1.9 liter TDI with a manual transmission. It is a sphere of liquid 0.1302 inches in diameter, a droplet a little...

Been there, done that! On the cars of your vintage, all the factory pans have the place for the oil sensor, very few have the option installed. If your pan is not completely destroyed, you can look for the sensor. The sensor area is a recessed U-shaped area about 3" wide on the bottom of...

On the hood latch pull handle, you can reach in with a needlenose pliers and grab the arm/finger that was sandwiched by the T handle and pull it while lifting the hood. The T handle that fell of is held on by a dainty clip and a very small pin. When they fall off, they sometimes get caught in...

I've seen brand new TDI oil pans with lots of micro-cracking as you call it. The cracking covers a large area of the pan usually. Is your cracking radiating out or in a restricted area near where it could have been hit? If not and its covering a big area like the whole bottom of the pan and...

No exp with A5 but too much with many A4s so with that in mind... Immobilizer immobilizes a couple of seconds after start and the symbol flashes on the dash. In other words, car starts normally and then dies. Don't consider anything in the fuel system until you get the starter cranking...

I've done this 4 times on IV Jettas and the New Beetle. Not possible for light to be turned off without fixing the air bag system. That involves new bags and new air bag control module and possibly the front seat belt(s). VAG-COM can do this. Previous reply from eetsoot regarding issues with...

On two of my three '02 TDIs, I've had the following fault: 17058 - Cylinder 4 Glow Plug Circuit (Q13) Electrical Fault P0674 - 35-10 - - - Intermittent or P0671 or P0672 or P0673 (the last number designates the cylinder number) First, I reset the fault code, took it for a little...

Re: FS: Plastic belly pan / skid plate (PICS!!) I do! I do! (want the belly pan). Sent email to you.
