    My car has now overheated three times. Each time the small 3/8" hose breaks off the NW16 fitting at the firewall. Has anyone had this issue? It's costing me a lot of money at this point for towing. Enclosed is a pic of the new/unused part and two pics of how it breaks. Thanks, -G

    If anyone has any suggestions other than what I've gathered from reading the archives here, please let me know. I have a 1999 Audi A6 2.8L AHA Tiptronic AWD. Summary: Coolant is leaking from somewhere that dribbles down around the oil pan. I hope it isn't the water pump but I didn't have an...

    Got the low coolant warning and looked for the source, which I think I found after pulling off the air pipe and housing. Looks like it's the top hose from the heater core at the firewall that runs back towards the radiator. Part number is 3C0-122-073-FC and if you go to ecs or google it you...

    My B5.5 1.8t is slowly losing coolant and I'm having a hard time locating the source. The plastic heater core and tubing seem a common culprit and while there are no clear visible signs of leaking, I want to temporarily disconnect the core to either identify or rule it out as the problem. The...

    My 09 tsi passat wagon definitely has an active coolant leak. I pulled the belly pan the other day just to do some routine inspection and saw that there was fresh coolant around this electrical connection. The source seems to be at the top of this pair of coolant pipes. Is this a common issue...

    Hi everyone, Hoping to get some help/guidance here after doing a ton of searching with nothing specific to my situation for my 03 Passat. I have a strong smell of coolant from my vents. Leaking core, right? That's what I thought, but the symptoms just don't add-up. I had the heater core...

    I went under my car today (2003 1.8T AWM auto triptronic) to inspect the transmission range switch (I have code P0706 -- that thread is here) and found dripping around the transmission pan but I don't think it's transmission fluid. It has a slightly sweet smell and I believe it's coolant leaking...
