What Went Wrong With Your B6 Today?..

[Spike00513]

Last week it was the dipstick tube shattering.
Today, it was this:

thanks for the warning. will check this out.
did you accidentally lean on it or something?

my dipstick tube looks pretty stale but I've already got an $8 replacement waiting to go in.
I fear it'll be the least of my problems, and the easiest.

Spike, I looked at it the wrong way. If you've got a replacement, get it swapped ASAP.

Oh and now..... it won't start. Just cranks over and over

Started with a shot of starting fluid

/\ Did you/can you pull Codes?

Pull codes for sure. Starting issue may be a few things. For starters, ( See what I did there :D) it could be a crank position sensor or your coolant temp sensor at the back of the head in the plastic flange. Either of these can cause starting issues.

Low fuel milage could be from bad 02 sensors, fouled plugs, MAF, clogged cat etc.

Jason

Codes as follows
PO172
PO117
PO175
PO421
PO431

And there was some freeze frame data from PO172

So 172, 175, 421, 431 are catalytic codes which the previous owner told me about them being clogged. But before I drop cash on catless downpipes I want to be sure I'm going to keep this car.

The coolant sensor is 117 correct?
The parts guy asked if it's 2 pin or 4 pin. I said get me both.
Should I replace the MAF too? $170 from my guy or $62 on amazon

Also. A coworker said I should turn the key on wait 10 seconds and then try starting. So far that has been working. So his theory is that fuel pressure is bleeding down. So now I have to track that down if in fact that is the problem. But the first time I had the no start I on and off cranked it for at least 10 minutes, on and off. That should have built feel pressure to start it.

Codes as follows
PO172
PO117
PO175
PO421
PO431

Sounds like you have more than one issue. Fuel pressure bleeding down would be the fuel pump check valve in the pump or leaky injectors. Since you are running rich, this may point more to leaky injectors. Below is all the info on your codes:

PO172
16556/P0172 - System Too Rich, Bank 1

Possible Symptoms
• Irregular behavior

Possible Causes
• Fuel system
• Excessive fuel pressure
• Leaking or contaminated fuel injectors
• Leaking fuel pressure regulator
• Low fuel pressure or running out of fuel
• Vapor recovery system
• Air leaks after the MAF
• Vacuum leaks
• Improper seated engine oil dipstick
• Stuck EGR valve
• Oil overfill
• Cam timing
• Cylinder compression
• Exhaust leaks before or near HO2Ss.

PO117
16501/P0117 - Engine Coolant Temperature Sensor (G62): Signal too Low

Possible Symptoms
• Difficulties with starting a cold engine.
• Starting the engine when engine is warmish or warm, idle rpm immediately is 1200 - 3000 rpm.
• RPM at idle is irregular.
• With all engine temperatures seldom idle rpm will vary between 900 - 1000 rpm.
• With engine warm (90 °C) the engine temperature suddenly drops (70 °C) and slowly comes back to 90 °C.
• Bad acceleration during warming up.
• Diesel: an indication is extreme long time burning time of the glow indication light.
• Engine Overheating

Possible Causes
• The electrical signal coming from G62 is too low
• Wiring and/or connections faulty (short circuit?)
• Engine Coolant Temperature Sensor (G62) faulty
• Mechanical problems in cooling system

Possible Solutions
• Check wiring and connections
• Check / Replace Engine Coolant Temperature Sensor (G62)
• Check cooling system and correct overheating condition if present
Special Notes*
• In MY 1995-2002 (?) in Europe at VW-cars the G2/G62 had the bad reputation of breaking down often. The default G2/G62 is black and all replacements are green.

PO175
16555/P0171 - System Too Rich, Bank 2

Possible Symptoms
• Irregular behavior

Possible Causes
• Fuel system
• Excessive fuel pressure
• Leaking or contaminated fuel injectors
• Leaking fuel pressure regulator
• Low fuel pressure or running out of fuel
• Vapor recovery system
• Air leaks after the MAF
• Vacuum leaks
• Improper seated engine oil dipstick
• Stuck EGR valve
• Oil overfill
• Cam timing
• Cylinder compression
• Exhaust leaks before or near HO2Ss.

PO421
16805/P0421/001057 - Warm Up Catalyst; Bank 1: Efficiency Below Threshold

Possible Causes
• Warm Up Catalyst Bank 1 faulty

Possible Solutions
• Check Warm Up Catalyst Bank 1

I don't have a funky idle. Not that I've ever noticed. Never "dieseled". Acceleration is good. Even though the variable intake runner thing is broken

I found injectors for $45 each. I'll replace them.

Any idea on why I run out of gas at 1/4 tank?

[Pswish]

It takes more work for the fuel pump to grab fuel below 1/4 tank so if your pump is failing, that would be a likely symptom. You should get a fuel pressure tester before throwing parts at it or you may end up chasing rabbits.

[Anthony k]

I have fuel pressure gauges
Just nothing to adapt to the Audi fuel rail

I fill it up now, every 100 miles or about every other day.

You can pick up a tester for 20 bucks at Autozone, or an affiliate in your area, which as the adapter for the shrader valve on the fuel rail.

How on earth did that happen?

Was washing my car and just when I was about to rinse the soap off. The faucet broke. I did have a bucket of clean water left so I thought strategically by pouring the water on the roof first. That way the water can cover the majority of the body. Unfortunately, that was a serious error.

It turns out the nut on the faucet cracked and broke in half. I turned off the main water valve to repair for now.

Ugh! Brand new AC compressor blew the rear seal after only 20 minutes of being installed! Cost me the $150 recharge - now I'm paranoid AND broke!

I suspect there is something else wrong or the rebuild was bad. Don't overcharge the system and make sure you're proportioning valve is good to go. Also, was this system properly evacuated and was the desiccant bottle replaced? What's the status of the pag oil in the system?

[ClimbCO]

A shop charged the system and said it was probably defective. As for the oil, I know it had about 4oz or 150ml when I installed the compressor - I've called 4 dealerships asking about the amount of oil and they all tell me something different. Nothing was replaced other than the compressor.

TY, will do

I heard the way it's set up, it's always spinning.
Maybe you will track down a shorter bypass belt to install, so you can drive without it in the meantime?

Well if it's charged, hopefully has the right kind of and amount of PAG oil, and is new, then that'd suck for it to have issues.

See this guy might now. I don't even know what a proportioning valve. I know there is a conical mesh filter thing, by the cabin air filter.
I've heard mixed opinions on whether to replace the desiccant bottle (it's called evaporator I think) but maybe it's cheap and could use it after so many miles?

??? how?
I thought cars were designed to withstand water. And they drive in the rain.

could temperature change cause it, if it was in direct sunlight and the paint felt hot?

[ClimbCO]

Yeah - not sure about the proportioning valve either, but the mesh tube is the orifice tube - it collects all the metal debris from the compressor. None of that was changed. I do have a belt that is on which bypasses the compressor, but it's getting really warm here...hahaha - gotta fix it soon.

[jacobsen]

Yes by proportioning valve I mean orfice tube. If you did not replace the desk can bottle may I ask how long it was disconnected and exposed to the elements? The trouble is it's a one-time use item, you have a very limited amount of time to hook up your AC system as soon as you open the desiccant bottle and install it. If you did not replace it it may have collected moisture and that may have froze inside your AC system. But if the entire procedure was done correctly then I suspect there may be something wrong with the pump remanufacture. What brand of pump is it Denso or Bosch or Valeo?

You have to place the system under vacuum for a while to confirm there are no leaks. This can help drive out moisture from the system the longer you keep it on vacuum.

Finally got round to investigating / replacing the passenger side fog/DRL light (in Canada).
Managed to get the grill off, despite one of the tabs being broken, so there was no where to put the trim tool to depress it.
Undid the 2, rusty and corroded T25 screws to pull the assembly out. Went to untwist the bulb to remove it from the housing, and it separated at the join between the plastic and metal sections of the bulb !?!
Looks like it had corroded away entirely. Had to clean off a ton of crud etc before removing the balance of the bulb by untwisiting it from the housing with a pair of pliers. It was only upon reassembly of the new bulb to the lamp housing that I noticed the housing has a major crack in it, which is most likely letting in water/snow/etc - this would explain the bulb corroding apart, the huge amount of crud on the housing, and why trying to get it back into the fascia opening was a little tricky, as it's "expanded" from stock ;)

But it works (for now) - now to figure out the intermittent 'Air Bag' light (only came on during the cold snap this week) and try an source a replacement glove box latch (release finger broke off a month or so ago..)

The joys of owning a 13yr old car with ~356,000 km on it :)

It's Quattro

Do I need any special tools to pull the pump?

There is no lower radiator hose on the passenger side. Check the turbo coolant supply and return lines.

Be sure to get a hella sensor. If not you may be replacing it again in a few months.

Apply upward pressure on the bottom of the glovebox lid/door as if you are lifting it up, then with the other hand open the latch and open the lid.
Don't lift the door away from the glovebox. What you want to do is align it properly as if it wasn't broken and then open it.

Pulled into my apartment garage and smelled burnt coolant which has me going 'uh oh'. Parked and popped hood to see smoke and brown liquid by turbo area. Then I took a peak under the car to see brown coolant which led me to check my expansion tank and voila, brown coolant!

So at 150k, would it be a blown head gasket? And/or oil cooler? Possibly a bad turbo coolant line?

What do you guys think?

[hightime80]

Goto autozone. Rent a combustion gas tester kit. Viola.
Been there done that. Oil cooler for me thank god.
