Today while reading with vagcom I had massive errors in memory inside.

here's a extract from it:

The air conditioner was turned off, maybe that's what it was?

What bothers me more is the engine failure. What can they be back to and what is the fault in the gearbox?

Someone's tip? I just recently put the 1500eur in the car, it's getting pretty slow.

Hi,

So the fault in the gearbox is gone. Get on the brake and he's gone. It's always like that.

Engine:
Bank 1: Lambda probe defective or plug or cable defective.
Fault lamp Kat! Is it in your station wagon? If not, see if the previous owner didn't take her out and if not, let's get a new one in.

Mtsg locked! Chipped????

Knock limit! What's your gas? Otherwise tap sensor cable check and when net goes away switch sensor.

Mixture adjustment Adaption limit: I also unfortunately did not find out what it is. And believe me, I've changed a lot.

Climate: Normal if you want to read it out, it turns on itself.

But important information is missing from you. Are the faults sproad or permanent.

Then wipe everyone out and go for a week and read out again. Then you can really say what's going on!

Hi Max,

erstmal vielen Dank für deine Tips.

Die Cat Lampe bleibt beim Starten etwas länger an, ca 2 sec. danach ist sie weg.

Ansonsten geht sie nicht an.

Das hatte ich schon mal bei Autobahn fahrt und da musste ich alle halben Stunde pause machen damit es wieder ging.

Damals waren es die Zündverteiler oder Zündspulen die neu reinkamen.

Gechipped ist der Wagen nicht und es wurde auch nie was verändert. Mittlerweile ist er seit 12 Jahren in meinem Besitz.

Ich tanke übrigens auch seit 12 Jahren und 220tkm Super 95, 98er hat der Wagen eigentlich nie gesehen.

Die fehler werd ich heute löschen und eine woche später nochmal nachsehen.

Der Wagen stand jetzt ca. 1 Monat in der Garage und lief beim Anspringen nicht auf allen Töpfen erst nach ein paar mal Gasgeben lief er wieder normal.

Er fährt sich auch ganz normal und braucht auch nicht mehr Spirt (ca. 20l in der Stadt)

Hi,

Oh, my God! Well, 20L are good for 4.2! I need some in town. 18L Super!

The fact that he does not run on all pots when starting can also indicate a dying ignition stage.

Had a friend of mine, too, and one week later he got a ignition level! There was then 1 cylinder complete. Dead.

Well, if he's net, the engine's probably gonna go. don't show it's locked.

You can go to the engine, too. log in, delete all errors, start the engine and give a bit of gas and then enter the error memory. Then he'd better be back on the hook. If the errors come back, you could see through the channels. There you see exactly whether the Lambda regulates or not.

It can also be that the errors add up and only 1 things are broken but isch then the whole progression. A defective lambda would also explain this with the Gemsichadaptation.

Hi,

I wanted to post just at the moment that the reached adaptation limit could indicate a defective Lambda probe!

I find 20l in the city for an A8 already violently, they should consume a little less than the V8 after all, and 20l with a 4.2r in the V8 was already with me the winter limit...

hi,

find ich eigentlich nicht so viel.

in den 12 jahren in dem ich ihn hatte hat er immer bei kurzstrecke an die 20l und mehr gebraucht.

manchmal komme ich in der stadt mit dem vollen tank nur 350km.

das trifft mich nicht mehr so.

autobahn geht auch mit 12-13l

nur die andauernden fehler stören und gehen ganz schön ins geld

ich werd heute die fehlerspeicher löschen und in ein paar tagen nochmal abfragen.

mal schauen was er da hat.

zündendstufe war wie gesagt vor 2 jahren schon mal defekt.

lambda wurden auch schon einmal getauscht

Hi,

That's another 32V-4,2? Hmm... he would then consume more than the V8, that I somehow can't believe. Unless you're talking about fast highway driving, but at 130km/h cut, I'm under 11 liters. With a 94 V8.

The 40V definitely consumes less, an average 98 A8 consumes 10.7 (long distance) with fast driving. My mech drives one, so...

mit tempomat auf 150 braucht er ca. 12l.

dann kommt noch ein wenig stadt dazu und der tank ist nach 600km leer.

Wie gesagt hab ich die 20l Stadtverbrauch schon seit Anfang.

Das sind halt Fahrten von 3 oder 5km Kurzstrecke dabei.

Wenn jede Strecke ca. 10km hat brauch ich auch nur 16l.

Was kann man denn da sonst machen?

Hi,

Yeah, that's gonna work out... Nevertheless, in the V8 we like to have the rule-crossings in connection with broken Lambda.
