3,500 miles and I just got the following 4 warning lights all at once!

[HWCN]

Audi Dashboard Warning Lights - Engine speed limitation - Yellow

Engine speed maximum XXXX RPM
The engine speed is automatically limited to the speed displayed in the instrument cluster. The engine speed limitation deactivates once the engine is not in the critical temperature range and you have released the accelerator pedal once.
If the engine speed limitation was activated by an engine control malfunction, the “Engine Control” (car with exclamation point) indicator light also turns on. In this instance, make sure to keep your RPMs below the displayed speed and proceed carefully to your Audi dealer to have the malfunction corrected.


Audi Dashboard Warning Lights - Central indicator light - Yellow

Central Indicator Light – Check the message in the instrument cluster for additional information.


Audi Dashboard Warning Lights - Engine control - Yellow

Drive system: malfunction! Please contact Service.
There is an engine control malfunction. Please drive slowly to your Audi dealer to have the engine checked.


Audi Dashboard Warning Lights - Malfunction Indicator Lamp - MIL - Yellow

The malfunction indicator lamp (MIL) is part of the On Board Diagnostic system (OBD II). The indicator light will turn on when the ignition is switched on and turn off again once the engine is started and running at a steady idle speed. The indicator light will also turn on if there is a malfunction in the engine electronics. Contact your Audi dealer to have the malfunction corrected.
Note: The most common cause for the MIL to turn on is an improperly closed fuel filler cap. If this light turns on, stop the vehicle, remove and replace the fuel filler cap, and resume driving. If this was the problem, the indicator light should go away shortly.


I am waiting on Audi to diagnose the problem. It happened while sitting in a mall parking lot. I am a bit bummed.

[BaltimoreCaesar]

Damn. I have no idea what that could be, but good luck man

[Paul@SupremePower]

A quick scan by audi will show what’s up.

Out of curiosity...Were you idling for a bit drove away and then this happened?

Or idling for a bit at all?

Yup. I was idling for a while in the parking lot.

[Paul@SupremePower]

Ok well the same thing happened to me and a couple of other ppl. Limp mode off idle in addition to some other codes. My car has been at audi for a week and waiting for a high pressure fuel pump from Germany. If they tell you the DTC is P0087 fuel pressure too low and/or P21F5 too rich off idle you may want to read the below.

Audi is going to start by replacing the HPFP sensor. That part is due in next week.

Do you know what codes you threw?

good to hear they are replacing the HPFP, did they give you any troubles with your tune?

[Potatohead_RS3]

HPFP sensor isn't a thing, they must mean rail pressure sensor which is separate from the pump itself.

[HWCN]

Do you know what codes you threw?

I do not. I will try to find out.

[HWCN]

good to hear they are replacing the HPFP, did they give you any troubles with your tune?

They are starting with a sensor replacement. They know I am tuned, but didn’t mention it as a concern.

[HWCN]

Sensor replaced and surprise, surprise, the HPFP is the culprit. At least a month until the part is in.

I am bummed!

[Paul@SupremePower]

Yeah this is going to be the next pita with this. Getting the pump. I’m plus 2 weeks.

[Canvasoso]

This sucks. Sounds like I won't be letting my car idle for long until they start getting some of these newer pumps here.

[HWCN]

This is my third new Audi/VW purchase. Thus far, the customer service on this problem has been lacking by both the dealer and Audi USA. If they can't step up there game, it will be my last.

It is particular frustrating that, I have more info about the problem via this forum then the Audi Tech at the dealership, and that Audi USA does not seem to disseminate and/or acknowledge a HPFP issue with the tech or the dealership.

[Potatohead_RS3]

You guys without cars for a month, the least you should complain about is getting a monthly payment refunded. That really bites.

This is my 5th new. In my experience they are kinda guarded with info in these situations until they confirm what’s up; even to their service departments. We’re particularly going to be in the dark due to it being so new and such low production numbers. I was just at the dealer and he said Audi is requesting all kinds of data and tests on mine like they are still diagnosing. The fact that they have it in there and spending time on it without even an eta on the hpfp speaks to that theory I think.

That’s fine with me. I’ll be a test subject for the greater good if needed.

[Paul@SupremePower]

I’m going to for sure.

Just aside note, most insurance will only cover a temporary replacement car for 30 days, if you get into an accident beyond that you are responsible. The way around it is to bring the loaner back before 30 days and get another one. The clock restarts for another 30. According to Geico anyway.

[DOCEVG]

..... I have more info about the problem via this forum then the Audi Tech at the dealership, and that Audi USA does not seem to disseminate and/or acknowledge an ... issue with the tech or the dealership.

There, fixed it for you, and turned it into a universal truth with dealerships and AOA.
Good luck.

[HWCN]

Dealership is stepping up. Pleased with that!

There are two ahead of me awaiting a new fuel pump. No actually eta.

[OE2]

did the OP have issues with fuel in the oil or was it just MIL and straight to the dealer?

[HWCN]

Straight to the dealer. I have no idea what happened other than 4 different check engine lights as indicated in original

[SpaTech]

Yup. I was idling for a while in the parking lot.

Thought I'd chime in on my RS3 I picked up last Friday ... knowing people have been getting errors off lengthy idle I was paying close attention and low and behold it happened to me. This happened yesterday ... idling for about 30 minutes (outside temp was 10F), temp indicator hit 222F and then threw up warning errors and went into limp mode (4,000rpm rev limit). I drove it gingerly for a few miles at decent speed and watched the temp drop to 206F within 5-6 minutes, still in limp mode and pulled over. Stopped engine / started engine and all good again.

Today, in Chicago traffic outbound this afternoon in what would be normally be a 10 minute trip ended up being 35 minutes of which a majority was stop/start under 10mph ... as I'm sitting there I watch the temperature climbing again 208, 210, 212, 214, 216 ... outside temp was 15F ... at this point I was starting to worry as I sit in traffic cooking my engine despite it being freezing cold out - what would this be like if it were 90F out?! Remembering back to the old days when many of my friends had big block V8's that had overheating problems they'd turn on the heat full fan speed to cool the engine down so I did exactly that ... cranked the heat, full fan speed, and like magic the temperature began to drop hitting 206F in under 10 minutes still in the same stop/start traffic.

What stuns me is that this is (essentially) 2018 and a decades-old trick of turning up the heat to open the ventilation through the engine block still works ... but it does highlight to me an overheating issue with the RS3's 5 cylinder ... I'm going to check my coolant levels when the car cools down just in-case it happens to be running low. Car has 600 miles on it

C'mon Audi ...

C'mon Audi ...

It likely wouldn't cool down at all if your coolant was low. Sounds more like a faulty/sticky thermostat issue here. Or...coolant simply isn't circulating like it should at idle. Why? Great question! I agree that this is quite pathetic for a 2018 model, especially one designed to be able to hit the track. What happens after a few hot laps and you come to a stop? Doesn't do very good for cool-down!

[BaltimoreCaesar]

The overheating you experienced at idle is not normal. I'm thinking you have an air bubble in your coolant system which is preventing the coolant from flowing freely through the radiator.

It sounds like the same limp mode off idle that has been happening to a lot of us except the overheating. Could you post your info and progress on this thread:http://www.audizine.com/forum/showth...-Idle-(Bank-1)

[Paul@SupremePower]

Are you referring to the oil temp gauge numbers? Normal op ranges 195-225 iirc.

Lower left side. The bottom bar gauge is coolant. The numerical one above it is oil temp. It’s being shown in C not F in this pic.

Thermodynamics hasn't changed since forever. But I am now cautious not to idle too long. This is BS to have to do this with a new car. While I expect that this will eventually pass one way or another, info from Audi would go along way. So far we have error codes, overheating, limping, port holds, etc. But the only thing Audi is doing is popping in fuel pumps with no explanation WHY they need changed. Does it effect all cars? And so on.

[defau1t]

216 doesn't seem hot to me. My lotus was one of my few cars that displayed coolant temperature in exact F. It would go up to 220s before the radiator fans kicked in at half speed, it would drop but if still stuck in stop and go it would creep back up and full speed fans would kick in.

Not sure how you are seeing exact coolant temps though - unless you mean oil temp? Take a look at allset's picture above, the oil is above with exact temp, the lower gauge is coolant temp but you have to guess at what it really is. I think car companies do this to not alarm drivers, coolant temp is always going up/down quite a bit. Unless it goes out of the mid range it's fine. I definitely paid too much attention to it in my lotus just because it showed exact temperature, and the car never came close to overheating.

Anyway, the indicator is not good news. I've sat in plenty of stop and go city traffic and never had any issues.

The off idle limp mode looks to be from low rail pressure not overheating. I think he may have been looking at the oil temp gauge which fluctuates from 200-225 under normal driving.

I agree Audi needs to pony up some info real soon on this issue.

[Potatohead_RS3]

I'm not trying to defend Audi here, but correlation is not causation. 225 degrees is completely within normal operating parameters for both oil and coolant. Cars of the last fifteen years or so run much hotter than older cars, they just do. I wouldn't be surprised if the fans don't even turn on until like 230. If I had my car already I would test all this stuff out. Because you "think" the car is overheating doesn't mean it's overheating. This is why coolant gauges in most cars now quite literally just stay in the middle between like 180 and 230 degrees, because people get concerned when stuff starts climbing.

For the rest of it we don't know anything other than there's some cars throwing codes. It appears as if there is a software fix in the works to correct it. It seems it is happening only on North American vehicles which points to a definite software issue rather than a hardware issue. This type of thing always happens with new engines/vehicles, it sucks that early adopters are beta testers but that's the way the world seems to operate now. It will get corrected and we will all move on and enjoy our cars :).

[Paul@SupremePower]

I don’t think his car wasn’t overheating. The only gauge that could have given that reading in that range was the oil temp gauge. The fluctuation seen between 200-225 is completely normal.

Gah! Let’s not add another problem to the list 😁

[OE2]

There has been some discussion that modern cars do an excellent job of sealing the engine compartment to the detriment of airflow when not in motion. I will be excited to figure out my rs3 issues and talking to some local guys about solutions.

Maybe, but I thought he correlated it to both warning indicators and also to cooling after he turned on the cabin heater. Sounds like overheating to me.

We don't know what his car threw codes for. We can be reasonably certain it's for the same stuff as everyone else since the cause and results are the same (long idle time and 4000 rpm limiter). 222F is likely not relevant, the fans don't even turn on until around there, and it sounds like that was oil temp anyway.

[lalalaprise]

and it sounds like that was oil temp anyway.

Of course it was Oil Temp ... the Coolant temp gauge doesn't read temps accurately...it goes to the middle and stays there.

I had the car for 2 weeks before I realized that the oil temp reading wasn't coolant temp lol <--- dummie over here

[HWCN]

Still no ETA on my HPFP. Spoke to Audi USA yesterday and thoroughly disenchanted with Audi's customer service. They have absolutely no clue. I honestly do not know what there purpose is.

[Greyout]

The current port hold is probably to fix this HPFP issue, even if they don't tell us it is. It's likely USA software/part problems. If they don't disclose they don't have to pay for a recall and get slammed with the bad press again. So they'll let the parts break and fix them on warranty or our dime. It's not like there are tens of thousands of these USA spec cars around, so the fact that there are multiple people with similar issues leads me to think these USA models have quite a few bugs in them.

Almost always true for first year cars, early adopters are beta testers basically. It could be worse, look at the Focus RS.
