Coolant Pump Recall

[BrewDude]

He performed a software update. It also reset all the Readiness codes.

Did you already have the ECM reflashed once? Looks like in the recall there's two criteria: install the plug and reflash the ECM OR install the plug with no reflash. I'm guessing that if the ECM wasn't reflashed initially for the aux pump then by all means it would need to be reflashed in this case...

This is the second notice on the aux pump. The first time was a reflash and the pump remained in place. The second time was a reflash and the pump was disconnected.

I believe the first reflash was to turn the pump off if a preset current draw was exceeded.

The second reflash blocks any DTC's that may occur from having the pump disconnected.

Can someone link/post where the afterrun pump connector is that should be unplugged.
Dealer is 1 hour away, pretty much a 1/2 day job to have it done there.
Might as well unplug myself.

If you unplug it, chances are you're going to get a CEL associated with it.

The details are in post #74 in the PDF...

The coolant pump is directly below the intake manifold.

Thanks. Do you have a zoom out photo of the location?

It is difficult to get a picture of the pump since it is located directly underneath the intake manifold. It is very easy to access. Just remove the engine cover and reach down underneath.

So with no pumps ready yet, an Audi mailer says to bring it in and they will disconnect the pump... any chance this would damage the car after a long drive?

I’ve had my 13 A4 for 8 months now. First Audi. Thank god I missed the timing chain fiasco.
But with this coolant pump recall, the heater recall, and a fairly extensive engine fix (thankfully under a warranty).... I’m seriously considering when it comes time to buy another car.... not just blindly choosing Audi. Sucks because I like the brand.

This fella lost his tune from the dealer reflash, then put the tune back on and is stuck with the EPC light. He just needs to plug his pump back in I'm assuming.

[Peter.dupuis]

I called to schedule the first part of the recall and they said they only receive 5 disconnect kits a week and are backed up for a few months. So I’m now on a waiting list

is this electronic coolant pump the same this as the water pump?

my water pump is leaking and i am also due for the recall

should I let them do the recall first? I dont want them to come back and say, we have to replace your water pump and charge me dealer price

[tominabox1]

It's not the same thing

So they won’t even touch the actual water pump when doing this recall?

The main coolant pump and the aux coolant pump are two separate things. Main is belt driven, aux is electric.

If your main coolant pump is leaking they'll replace it. Since you have an open recall they'll disconnect the aux, put the jumper plug in, and reflash the ECU.

We're all on the waiting list for Audi to receive the new aux pumps, expected time frame is December last I heard.

I am doing the recall next Tuesday. I called them and they said it was available

When you say they will replace it, as in as a recall or they will charge me?

Does this recall cause the main pump to leak?

You're confusing yourself.

If your main cooling pump is leaking this is not covered under the recall. If you're under warranty still then it will be replaced gratis, if not you'll have to pay to replace it or DIY it.

This recall does not affect the main pump. It is for the electrical aux cooling pump that runs when the car has been shut off to allow coolant to circulate.

[tominabox1]

They will inspect your car and find the leak and offer to fix it, at your cost (if out of warranty). It will not be replaced without your approval, it is not part of the recall.

[f_399]

Okay that’s better clarification, thank you!

Can’t the recall part ever leak?

Trying to see if I should get the leak foxed first at an independent shop or have them do the recall?

Do those two parts share labor? I.e.removing the same parts to access? “While your in there”

I do not know that one. You could always ask your contact at the dealership

The first fix of bypassing the pump, does the reflash wipe out a tune?

Uhh...yeah. Whole reason why I haven't done it.

If it hasn't spontaneously burst into flame yet, I can wait for the pump replacements to show up. By then my CPO warranty will be over and I could care less if Audi flags it.

[f_399]

Cool thanks!

Is it something they have to do even if you go in for an oil change?

I am scheduled for the recall but after reading this I don't want to do it unless they have the actual part.

I do need an oil change though, hoping its not something they have to do.

If you go in for ANY reason they will do the recall unless you decline it, and that's a whole 'nother bag of worms.

If you're still under warranty and aftermarket tuned, more than likely they will flag the car TD1. Only way I've gotten around this is to go to my local APR dealer and reflash the car to stock, then have the dealer do the work, then go back to my APR dealer and reflash the tune.

HOWEVER, none of the aftermarket tunes have coded out the aux coolant pump, so if Audi does the jumper plug mod to disconnect the pump and you go back to your aftermarket tune, you will get a CEL because of it.

TL; DR park outside if you're worried about the pump catching fire and don't want to do the recall.

[f_399]

I am not worried about td1, out of warranty already I just don’t want to be out of the tune, I only have the car a couple more months, I’d like to enjoy it lol


Has anyone done the recall with the part replaced? In that scenario, can you go out the tune back in with no issues?

See post #89.

FYI NO ONE has had the aux cooling pump replaced due to this recall. New pumps are expected to be in by late December.

This isn't true. I went in last friday for an oil change and they did not perform the recall. While speaking with the service advisor I mentioned to him I DO NOT want the first phase of this recall done because 1) I'm not comfortable disabling a pump thats suppose to be on and 2) I don't want my carista mods erased. He told me no problem because they only have so many "recall kits" available in shop and you have to be scheduled for the work anyway.

So then you declined to have the recall done. Totally true on what I said.

Any mods you've done via Carista are not done to the ECU.

Just relaying what the service advisor told me... "we won't do the recall because all the "kits" are spoken for and you have to be scheduled for it anyway"

Yup...standard Audi operating procedure.

just to clarify for anyone wondering, i had a coolant leak and i thought it was attributed to the recall so i brought it into dealer. My coolant leak is bad, im going through roughly a gallon of (50/50) coolant a week ( i have since stopped driving it).

The dealer did the 80c6 recall to replace my aux heater, and they performed 'adaptations' but they said my tune wasnt flashed out..... they found the leak and attributed my coolant leak to the water pump, which was going to be $1300 to repair. I said F*ck off and ordered the parts through ECS and am doing it myself. The good news is i paid nothing for them to find the problem (which is sometimes the hard part).

Do you know if your water pump is leaking due to a valve cover oil leak? I noticed mine was leaking from the valve cover so I got it resealed and the shop said if not resealed it can cause water pump to fail due to the oil getting on the water pump.

I was told coolant was leaking from seals within the water pump, it is always recommended to replace whole housing then to just replace seals, which is what I’m doing....

Unrelated but my vacuum pump is leaking oil onto one of my coolant lines, so I’m replacing that too

Oh I see, I haven't had any problems with my water pump. Are they known to go out ? Mines about to hit 67k

i think the seals get weak over time...and the thermostat is prone to failure, but overall i don't think its a common issue. My car has about 85k miles FYI.

Let me know if it’s a hard process replacing it yourself , thanks for the info

Shouldn’t be too bad, I already have it mapped out.

1. Drain coolant
2. Take out coolant overflow res tank
3. Take off intake hose
4. remove throttle body

Then you you can access the water pump, replace, and reverse order the above

[ps2cho]

Took my Allroad in for a key programming, and left with the coolant afterrun pump recall completed, dang it.

I'm most concerned over this damaging the turbo. Anybody just simply reversed what they did and connect the plug back in?
Alternatively, would it be advantageous to basically keep RPM's very low towards the end of any trip, then let the car idle for 1-2mins in park before shutting off?

Also what debris will clog? Aren't we done with the days of sediment/rust with the advances in coolant tech? If there is a debris in the system, that is telling me that we need to be flushing the coolant earlier than stated, ie: every 50k miles...I'll probably add that to my list of things to do.

[f_399]

Did they ask if they could do the recall?

I went in for an oil change and told them specifically not to do the recall
