Shop Audi Water Pumps

Hi, my audi has a coolant leak. I thought it was the reservoir and yesterday I discovered it is something else where the coolant is leaking. I parked my car yesterday across from redbox. The car was idle and in park. And I spent about 5 min infront of redbox; I turned around and mostly all the coolant had leaked under my car. I opened the hood and saw the coolant leak. I made a video. Any ideas? Please advise what I should do. What parts I can buy?

THANKS!

That video doesn't tell us much. It will have to be examine closer and maybe from below but it's in the general area of the water pump but the timing cover is hiding that.

Hello! I had just gotten the timing belt and water pump replaced by an indie shop two days ago, in preparation for a cross-country drive back to CA from NY. Around 4PM today, the air coming out of the vents began to feel significantly less cool. Eventually, (to quote Jeremy Clarkson) the air like an asthmatic wheezing through a straw. I noticed water (or a substance similar to water) dripping down onto the front of the passenger side footwell, and I noticed a sound like burbling water, sounding kind of like a small water fountain, coming from the air vents. In addition, there was a bit of condensation on the plastic slats on the air vents.

Is my AC failing because of the humidity and heat, in addition to running at 60+ mph for over 10 hours each day? Or is this a more serious issue linked to my cooling system? I still have 1,600 miles to go before arriving back at home, and I'll have to cross Texas and Arizona in the summer heat. Should I delay my trip and get this issue fixed ASAP?

PS - I found the following post on another forum, and was wondering if it was also relevant to my issue:

"This is a shot in the dark, but I might know what's up. First, I have never heard of an air bubble in the coolant system making a noise you can actually hear. I'm wondering if the noise you are hearing is water trapped in the heater vent system. When the A/C runs to cool the air, any moisture in the air will condense on the cooling fins. This moisture collects and drains out of the heater box through a little tube. With like 99% of car this tube goes back trough the firewall and just drips on the ground near the back of the engine compartment. If something blocks or freezes in this drain tube, you could have a lot of water trapped in the heater box. I don't know where "Bloomington" is but if it has been cold maybe water froze in the drain tube. A leaf getting into the wrong place could also stop it up. It's happened to me with other cars."


PSS - I also found a post on a FIAT forum from someone who heard water gurgling from behind their dashboard. Not long afterwards, their headgasket blew. Will the same thing happen to me if I don't get this fixed?

Sounds to me like you simply have a plugged up condensation drain. You will have to locate the drain on the engine side of the firewall and blow it out with compressed air.

bugbehr: The reason if just water is just as HT said. If just water it would dry out on a paper towel, antifreeze wont. Hope not that! You are underway now apparently now and yes headed for likely hot weather as you said. Short of tools if you can find the drain on firewall at least see if it's intact.

Why did you check a FIAT forum for an Audi? The most common reason for head gasket failures is overheating IMO not inoperative A/C but since you just had a water pump done and may be late, check coolant level as if low after the work done could be the most important problem now. No engine no A/C anyway and worse - walking or towed to next place for more possible repairs.

Suggestion: If doing preventative work prior to a trip of the sort that long especially best to do ahead when at all possible so it proves itself fixed as breaking down on a long run from known places is a nightmare. Good luck with the run.

If you must this (condensate drain) ((Water)) could probably be solved at some truck stops places quickly unless in some very difficult location could be a while you wait fix,

Hi Forum,

First post here. I've been searching for 'scope traces showing the cam and crank sensor together. Saw some on this site and hoped someone may be able to point me in the right direction for my car?

I've had an ongoing cam sensor issue that started when the water-pump failed. All new belt kit then (it seems) the cam sensor is not matching up to the crank sensor. Crank sensor probably OK as engine will run without cam-sensor. Nice 50% square wave from camsensor. Possibly very slight wear in crank sprocket key-way - no better with new gear/key.

MIL on, code 0340 no car/spanner lamp.
Clear all codes
MIL off, car/spanner lamp on. 0340 pending.
300 miles later:MIL on, code 0340 no car/spanner lamp.

I have a scope but have no idea how the two signals should relate. Looking at cam sprocket, the sensor switches at (crank angle) 30 degrees after TDC(fired1). The sensor then remains switched for 1 crank revolution, switching back at 30 degrees after TDC(fired3)

This sort of on/off cam sensor (on for half a cam rev, off for half a cam rev) seems very simple and I hoped it was just to indicate which cylinder should be firing, but there's lots online about the ECU being really fussy if the timing is very slightly off (but no diagrams or info on degrees between the sensors output).

Thanks for reading and all help appreciated.

Hi Hammer,

Thanks for the response.

The reason for posting here is that this is a US site and tech info is therefore more available.
The UK has losts it balls when it comes to repairing things, we simply give them to the garage who replaces part after unnecessary part until the customer runs out of money or the garage finds a fix by luck. Not a viable option for a low value car like mine when garages rip us off at >$120 an hour.
The Zx18xe engine isn't just limited to loads of Opel cars but also appears in Audi (if you're unlucky). Fortunatly the Zx18xe1 and Zx18Xer are also suitable for my question, I should have indicated that initially, sorry.

Thanks anyway,

Kbs
