Default heat back on

Audi advised today they feel it is a plugged core from sediments????
$1500 to remove dash and replace core.. No warranty coverage.

I will ask re the tsb and if thye updated all, also if they back flushed as they put new hoses on and flushed a few months back to try and correct the problem.

Here is a tsb link, http://www.allworldauto.com/tsbs/ is it 10015099 in the engine cooling section?


Thanks,
Seems when the dealer did previous engine work the rookies techs did not bleed and or install gaskets right.

During this visit they repaired some oil leaks and refitted gaskets as well as a proper bleed of air.

Hot as day one...

And how much are they finally going to charge you for all the non-required work they did to fix a problem they caused in the first place? I think I'd have an attorney ready to go if they tried to charge me for anything - new parts included. Their failure caused the issue, their subsequent failure caused misdiagnosis and the unnecessary replacement of parts. Should all be at their cost, to include all labor.

Default Made some heat work

Well I finally got yelled at by my wife enough to go out and spend the day under her son's car with his Pollock dad standing there laughing that it would not work. I guess a Pollock that hangs out at a friends shop thinks he is ASE by virtue of hanging out. So I got my 2-2l soda bottles with hot water and CLR, attached a hose to the bottles and pulled off the hoses to the heater core (of course I opened the cap to the tank first). I put the empty bottle on first and attached the other to the core. At first I could barely push anything through so I let the CLR solution sit in there and kept trying I kept pressure on it and then A big piece of gunk came out to the dismay of the laughing Pollock. I worked the stuff back and forth several times and got some nasty looking crap out of the heater core. I changed the water with a little less CLR and worked that through it. After that I started to rinse it with straight water. It took several changes, but I finally got to the point where the water came out fairly clear and flowed fairly fast.I had one moer time through with only one bottle on the inlet and the hose to a bucket and the water flowed nicely. I put the system back together and added coolant and started it back up. We now get heat when the car is driving and after a lot of revving sitting on a hill there is some heat when idling. I am considering letting a shop do their fulsh on the system to get the last of the air out, but now the core seems to be clear. If anyone is having this problem, I would suggest avoiding the nay-sayers and trying this trick.

Now you have to bleed the core......fill up and unfasten the expansion tank, raise it up and place a block of wood under it keeping it as high up as possible. Now partially remove the upper core hose so that the bleed hole in the hose is out past the core flange. Rev the engine to 2500rpm's and wait for the air to bubble out of the bleed hole. Be patient this will take maybe 15 minutes. Keep the tank topped off during bleeding.

IT'S A BLEEDING ISSUE. If you run the car to operating temp and pull the heater core inlet hose off, you will NOT, have a steady flow of coolant. You need to bleed the core at the inlet hose. Sometimes it takes holding the accelerator down at about 2500 rpm for approx. 15 mintues before you will even see a flow of coolant come up through there. It's the way this system is designed. The heater core is basically a bypass with a slow moving low pressure of coolant flowing through it. Trust me and don't give up. Bleed over and over again and can take a lot of time in most cases. There is a great DIY on Audizine that I went by and got mine to work. I'll try and find it and put up a link.
Reviving an old thread here - I'm working on a guy's 2003 B6 1.8Tqm, trying to get the heat to work again. I did a timing service on this car a few weeks ago, bled the system properly, and all is well in that regard. However, the car had zero heat.

He bought a heater core and left it with me in the event that it has to be changed out. Meanwhile, I figured the flush and reverse flush was well worth the effort before tearing the inside of the car out to replace the core. I have flushed and reverse-flushed it several times (although not yet with boiling water and CLR as suggested above - going to head to Lowe's to get some CLR and do this). What I have done is flushed the core in both directions half a dozen times each, clear fluid coming out, and bled the system. I pulled the upper hose out to expose the bleed hole, raised the expansion reservoir, and idled/revved the car until it gave a great, steady, peeing stream out of the bleed hole on the heater outlet hose. Put the car back together, popped and topped the coolant, restarted the car, and still no heat.

I know that the hot water/CLR may well dislodge something that the garden hose flushing did not, but in the event that it doesn't, does anyone have any further ideas on what to try? I'm waiting on a guy I know to bring over his unlocked VagCom so we can do the climate control fault code scan (my shareware VagCom has never been able to read CC codes), in the event that it's the blend door.

Just wanted to throw this out here to see if anyone has any further ideas - TIA...

Default Resolution to Heater issue:

Here is what i did to fix it:

Got in my car, got the RPM's to about 2500, drove to the Volvo dealer, traded the Audi in, took a Volvo home. Wrote a letter to Audi in German, sent to Germany headquarters, wrote another letter in English and sent to US headquarters. The Germans responded, the US letter was never acknowledged. The Germans actually were concerned that they found record that Audi USA had replaced my CV boots four times with incorrect part number. Possibly why it tore 4 times in 2 years. They were very polite & apologetic, Audi USA has yet to respond.

I will never buy another Audi. I recommend all Audi owners do the same. It was worse than owning an American car. My S40 is a wonderful car. The shop is fantastic, and the car is reliable. The Audi was sexy & fun, but it was a big hunk of ****.

BTW the Volvo shop spent 15 minutes on the heater issue...it was a head gasket leak. Audi shop never checked that, I guess if you spend four thousand dollars they only check non-gasket causes. You need to spend more than four grand before they check all possible causes. The Volvo tech checked the contents of my oil...it had coolant in it. This is an indication of either gasket, or cracked head. I graduate in the spring, and will be buying a 2011 Jaguar XF. Yes, I have more confidence in Jag than I do in Audi. Audi cost themself a $50,000 purchase every 3 years by hiring inept techs who, as ambassadors of a brand have made Audi look silly & as appealing as the Post Office.

Copy of correspondence sent to Audi. This is what I had to do just to get an apology.

Edmond (USA), den 30.01.2010

Sehr geehrte Damen und Herren,

mein Name ist William xxxxxxx. Ich habe meinen 2001er Audi A4 2.8L Quattro von Bob Moore,
einem autorisierten Audi-Händler, 2004 gekauft. Es war ein Gebrauchtwagen, jedoch in sehr gutem
Zustand. Ich habe alle obligatorischen Wartungen am Fahrzeug vor, oder zum empfohlenen
Zeitpunkt durchführen lassen.

Im Winter 2005, begann die Heizung nur noch kalte Luft auszustoßen. Ich machte mir keine größeren
Sorgen, da ich noch Garantie auf das Fahrzeug hatte. Ich brachte das Auto in die Werkstatt, wo
festgestellt wurde, dass der Heizkörper ersetzt werden musste. Das Teil wurde bestellt und der
Schaden schließlich repariert. Als ich das Fahrzeug zurückbekam war es bereits warm draußen, da
der Sommer begonnen hatte. Als ich die Heizung zu diesem Zeitpunkt testete schien sie zu
funktionieren. Im darauf folgenden Winter 2006 musste ich jedoch feststellen, dass die Heizung
wieder nur kalte Luft ausstieß. Meine Garantie war bereits abgelaufen und Audi verlangte 100 US-
Dollar um das Problem zu diagnostizieren. Es wurde keine Fehler im System, seitens Audi, gefunden.
Da ich in den USA hohe Studiengebühren zahlen musste und keine ausreichenden finanziellen Mittel
besaß, entschied ich das Heizungsproblem ungelöst hinzunehmen.

Als mein Vater davon erfuhr, überzeugte er mich dem Problem weiter auf den Grund zu gehen, da er
es absurd fand ein Auto ohne funktionierende Heizung zu fahren. Als es Zeit für den zweiten
Zahnriemen war ließ ich gleich mehrere Teile austauschen um das Heizungsproblem evtl. zu lösen:

Wasserpumpe
Thermostat
Kühlflüssigkeit
Kühler (bereits vor Zahnriemenaustausch)

Doch wieder konnte keine warme Luft produziert werden. Mein Vater, der nur wenig über Audis
weiß, war aber aufgrund seiner Mechanikerausbildung, der Auffassung, dass europäische Autos dazu
neigen Luft im Kühlungssystem aufzuhalten. Wir entschieden uns eine Reparaturanleitung zu kaufen
und lösten das Problem schließlich. Meine Heizung war nun wärmer als jemals zuvor seit 2005. Das
Problem war jedoch das die Luft nach ein bis zwei Tagen wieder begann kälter zu werden. Die
Reparatur musste ständig wiederholt werden um wenigstens eine minimale Heizwirkung zu

ermöglichen. Die Luft war nun wenigstens warm, jedoch war es nicht möglich mein Auto vollständig
zu erwärmen. Ich brachte meinen Audi nochmals in eine Audi zertifizierte Werkstatt und erklärte
mein Problem. Dort wollte man den Heizkörper erneut austauschen.

Wie kommt es, dass Audi von meinem Geld Teile austauschen will, die bereits getauscht wurden? Es
wurde über mehrere Jahre mit tausenden Dollars ohne Erfolg versucht meine Autoheizung zu
reparieren. Mein Vater benötigt hingegen nur 45 Minuten um die Heizung, zumindest teilweise, zum
funktionieren zu bringen. Luft wird ins Kühlsystem fehlgeleitet und Audi ist nicht in der Lage es
rauszufinden. Warum meine Heizung nicht funktioniert ist mir mittlerweile egal.

Die Frage, die ich beantwortet haben möchte ist:

Wie kann Audi mit all seinen Möglichkeiten und seiner Erfahrung nicht in der Lage sein mein Auto zu
reparieren, mir jedoch das Geld aus der Tasche ziehen?

Des Weiteren ließ ich eine Antriebsmanschette austauschen. Wie sich herausstellte baute man mir
eine falsche ein, was auslaufendes Öl zur Folge hatte. Die Liste von inkompetenten Versuchen mein
Auto zu warten ist erschütternd.

Unglücklicherweise ist diese die einzige Werkstatt die auf Audis spezialisiert ist. Eben bedauerlicher
ist, dass ich mich mit Audi USA und Audi-Händlern auseinandersetzen muss, die ihr
Qualitätsversprechen nicht einhalten. Abgesehen davon, mag ich mein Auto sehr gern und habe
großes Vergnügen es zu fahren. Ich werde dieses Jahr meinen Uni-Abschluss machen und hätte mir
sehr gern einen neuen Audi gekauft. Jedoch habe ich Angst die gleichen Erfahrungen machen zu
müssen. Aus diesem Grund werde ich keinen Audi kaufen. Ich habe versucht Audi USA zu
kontaktieren, jedoch ohne eine Antwort zu bekommen. Als letzten Versuch habe ich mich dazu
entschlossen, mein Anliegen ins Deutsche übersetzen zu lassen und sie zu kontaktieren.

Ich bin absolut empört und fühle mich von Audi ausgenutzt. Vom Audi-Händler in den USA habe ich
nach all den Stunden und Dollar, die investiert wurden, nie eine Entschuldigung gehört. Ungefähr US
$ 3.500 habe ich für das Heizungsproblem ausgegeben, ohne ein zufriedenstellendes Ergebnis erzielt
zu haben.

Ich habe meine Erfahrungen nicht vielen Leuten berichtet, jedoch kann ich ihnen versichern, dass
wenn ich jemals über Audi gefragt werde, nichts Gutes zu erzählen habe. Anstelle, werde ich den
Inhalt dieses Briefes und ihre Reaktion, die ich hoffe zu erhalten, berichten.

Mit freundlichen Grüßen

Default Trade??

So you went and traded you Audi in for a fancy Ford, and after you graduate you plan on buying a really expensive Ford. Yeah the Audi's have problems, but in May mine was totaled and I have missed that car since. I apparently got such a good deal on mine that I could not find another like it to replace it. I actually got $1k more than I bought it for after I put 50K on it. I am still impressed with the cars.

I had never looked inside a heater core before. Once I cut one open I saw why it is so hard to get one flushed out. There are little spiral inserts in the tubes that slow the flow of coolant so heat can be extracted efficiently. On this particular car we tried a BG cooling system cleaner and the heat improved but was not fully restored. All of the passages were clogged up with a brownish residue. I have some photos on my facebook page.
