Have you ever worked on a VW? I can do most work on my GTI with basic tools. Sure there are some specialty tools/sockets that may be required but many cars require special tools depending on what you're doing.

I've done headgaskets and overhauls on 80's-92 VW Jetta, Rabbits, Foxes, and Scirroccos gas and diesel with basic metric tools and the occasional torx

Anybody have some good prices on 1.6l NA Headgaskets with solid lifters? I'm getting prices between $25 and $35. I'd like to replace the head-bolts with something a little more sturdy as well, any recommendations? I was looking at ARPA racing studs

Hope this is an appropriate place to post this.

I have a 2001 Audi A4 1.8T Quattro, about 110k miles on it.

I was on my way to run an errand this afternoon, and while trying to back out of my parking spot I noticed that the power steering was "catching" and making noise. It seems that the hydraulic line that runs underneath the front of the car must have caught on something at some point. It's hanging down from underneath the front bumper and leaking fluid.

Strangely enough, my wife drove it an hour before and didn't report any problems nor does she remember hitting any potholes or anything like that. Some pictures:

Two questions:

1) Does it look like this repair is going to be more than just replacing the hydraulic line and refilling the fluid?
2) What would you estimate the cost of this to be (in terms of parts and hours in labor)?

I'm going to call the repair shop first thing Monday but I want to go into it a bit more informed than I have for past repairs.

Thanks!

Ummm, that looks like a Transmission Oil Cooler line...is yours an automatic?

Anyways, if the power steering pump is burned from fluid loss and heat, then you'll have to have that replaced as well

When you shut the car off and get out a fan starts whirring so I think it already has methods to cool itself.

The main worry is oil to the turbo, if the turbo does not have a resevoir or bath, then shutting off the car too quickly after having the turbo spooled can leave the turbo without oil to lubricate it as it spins down.

But it should only take about 15-20 seconds for the turbo to de-spool and enough oil to be present for engine shutdown

I believe that any of the turbo VW/Audi cars have an after run coolant pump to circulate coolant as well as the rad fans running after shut down. We've got one customer with a highly modded 2.7T that has an aftermarket turbo timer as well but generally a stock motor doesn't really need it.

Heck, my 1981 Rabbit, 1989 Jetta, and 1991 Jetta will run the fan after the car is shut off if the coolant is too warm. Mainly because the fan relay is triggered via the sensor on the radiator which is wired directly into the 12v battery line

From what I've read about the 1.8t and 2.0t they have some sort of evaporative cooling for the turbo so that you don't have to let it idle. My dad's 1.8t made it almost 250k miles and he never idled it before shutoff. I've been told that unless you are doing 4th gear pulls into your garage then shutting it off, there's nothing to worry about.

The thing to remember is that turbos are pretty drat common on cars these days, so they have to be built for the average moron to not destroy them.

You STILL need to let it idle for lubrication purposes, at LEAST for a little bit to let the turbo spin down and lubricate before shutting down. We JUST had to replace a turbo on a truck because people don't let it idle down before shutting down. That thing spins so fast that if you don't let the bearings lube up before shut down you will lose that turbo eventually.

Granted, turbos are much more moron proof than they used to be, none the less erring on the side of caution is better than having to replace a turbo that you did not have to replace

I've never replaced a turbo for anything related to coking or insufficient cooling. Excessive shaft end-play? Certainly. None of our turbo owners (diesel or gas) ever let their engines run at idle before shutting them down - for the most part because it never occurs to them and it's not mentioned in the owners manual. There's literally no reason to do it on a stock turbo'd VW/Audi anyway - they just don't require it.

My bad then, maybe I'm just too used to working with trucks :(

No bad at all! You're totally right about big turbo diesels. I'm a little more used to imports with big aftermarket turbo kits and they NEED timers and after-run setups to prevent damage too.

Yes, I am used to working on aftermarket turbos on old 1.5l and 1.6l VW NAs we turned into TDs. Also, the turbo on my 1972 Willys M35A2 is always spooled even at idle, so the biggest issue is you have to make sure to let it idle down before shutting it off

I have a question actually:

I am preparing to replace the pistons in my VW Rabbit 1.6l Diesel, I have to remove the ridge that has built up on it and it needs oversize pistons. How do I tell which pistons I have currently (I suspect they are OEM) without remeasuring the current cylinder bore? There is something stamped upon the pistons, but I cannot find any references for the markings

I am planning on replacing the pistons with the turbo pistons as I have installed a turbocharger.

My Audi hates me and the feelings starting to become mutual.

2003 Audi A4 1.8t with around 80k.

I cannot, for the life of me, get these cooling problems to go away. I have already replaced the thermostat and a fan module, and 2 other components I don't even remember the names of. The warning keeps returning after a week or two, and my needle keeps running into the red. Does this godforsaken engine have any "famous" problems with the cooling system I need to know about as well? It seems like everything that happens to this car, from both window regulators breaking on the same day, to the strange phantom noise I hear when sitting in the car with the engine off (sounds sorta like a ghost is adjusting the electronic side mirrors. All loving day. Forever), everyone who owns a B6 is like "Haha yeah they're known for that."

This car is frighteningly close to getting driven into a wall intentionally.

Water pump?

Any bubbles in the cooling system while the engine is running?

Yeah, waterpump - they're famous for making GBS threads the bed on the 1.8T. Pull the thermostat out and feel around in the cavity it sits in - I bet you'll find pieces of the water pump's impeller. The ghost noise you're hearing is most likely the HVAC system moving the blend doors after shut-down - it's a common enough complaint but not a problem usually.

They are fairly famous for making GBS threads the bed in most Audi/VW products, especially when they had that damned plastic impeller.

Makes me glad my TDI got upgraded to the metal impeller

This week I installed a replacement auxiliary radiator fan on a 2.5L 2007 Jetta because Germans hate cooling systems, for some strange reason I'll never understand. :argh:

From what I've read, the auxiliary fan failure is pretty common and a well-known failure, but my wife brought up a good point - the larger fan had to work overtime to compensate for the smaller fan being dead for the last two months or more, so wouldn't that place more strain on the large fan and cause it to fail somewhere down the line, as well?

Has anyone with a similar Mk5 Jetta experienced issues with the bigger of the two radiator fans?

I don't know when they changed it, but on the Mk 3 the fans are actually driven by a single motor and a belt drives the other fan linked to the fan with the motor

Audi 4000 Quattro, clutch won't disengage properly and I changed the clutch and pressure plate to try to fix it, no change, and this mechanical clunking and clinking happens when I rev the motor. The two symptoms appeared simultaneously


I'm getting really frustrated, what should I do?

My current thought process is to replace the slave and proceed from there, I'm getting apprehensive and thinking about removing the head to check for damage. It idles fine though and does fairly well when revved, the sound come and goes, so its not consistent like a lifter or valve.

They are much cheaper than the last Jetta. If she insists on going with one, look at the GLI, it has the proper rear suspension and the upgraded interior. Also has the 2.0t. Or the TDI. The base 2.5s are going to feel super cheap, as they are, considering they are 17k cars.

To be honest, the TDIs get a little better interior than the 2.5 and 1.8/1.8T. And after sitting in a recent Ford and Chevy, the interiors still feel much less 'plastic' than their American counterparts.

How much of a pain is it to do an oil change on the TDI? First 3 services were included with the free maintenance.
