‘23 Q2 Sport 35tfsi. Engine cutting out.

[Oldnuff]

Random engine cut out at junctions.  On one occasion car started rolling into busy roundabout through engine cut out after waiting in first gear with clutch in.  Any details of similar experience welcomed

Not heard of this before, might be worth having a diagnostic check to see if any fault codes flag up

Booked in for diagnostic test

Hello,

I have a 24 plate 1.5 tfsi sport Q2 and have the same or very nearly the same experience,I’ve owned the car 5 months and my wife and I have both had this while driving as you say approach to junctions or roundabouts, I thought it was me having changed from an automatic diesel vehicle to an unfamiliar manual petrol and not driving it as I should. But my wife has had the same issue and usually drives her 1.5 tfsi golf , I’m hoping it’s me not quite driving it correctly, deep down I don’t think that is the problem ,If it is the car then it’s a bit worrying- I’ll watch this thread with interest.

best wishes 

Mark

Those were my thoughts exactly. I’ll copy this to Audi Cardiff where I have an appointment with service staff on Wednesday. 

[Ralfolly]

Hello Brian,

i hope you have a positive appointment, I have decided to make a record of this ‘fault” occurrence and also drive through the different modes.. currently using “auto” mode exclusively but will change modes just to see if any difference in the car , the only thing is the “fault” manifests itself randomly when least expected .

regards,

Mark

As you say it comes as a complete surprise.  Have you had any messages on the dash.  On my last issue whilst on flat ground in traffic a text message on the central screen read something like “drive system inoperative - please restart the engine”.  Given that the first time this happened it rolled forward onto a roundabout does this mean the drive system is disengaged?  Only just thought of that.  It was a shock at the time so I didn't know what was happening and just needed to get out of the way

[Ralfolly]

Hello,

yes this message “Drive system please start manually” — 

I’ve just been reading owners manual page 90 - 91 the pages relate to start/stop system and it’s referring to certain conditions not being met therefore the engine may be switched off before the vehicle has come to a standstill .

The basic conditions are listed midway page 90 , there’s also an information note a the foot of 90 stating in certain situations the engine may stop earlier while the vehicle is still COASTING , 

[Oldnuff]

Interesting.  Let’s see what they say on Wednesday. 

[Oldnuff]

To reiterate the issues I’m experiencing I have had five incidents since buying my Q2 35 TFSI new a year ago.  The first happened when the car rolled without engine power onto a busy roundabout as I took my foot off the brake. Pumping clutch and accelerator had no effect.  Scary!  Luckily I had enough time to restart engine.   

My local dealership looked at car again yesterday but could find no error codes when interrogating car’s memory. The message “drive system inoperative- please restart engine“ on central dash in latest incident is a driver information message and not an error code.  Discussed info on P.89/90 of the car’s handbook with master technician who said that he thought that “driving style” (see manual P89) meant certain situations could result in “overwhelming” the software system and the engine cutting out. He couldn’t specify which situations.  He did say that he has seen other similar issues none of which were pursued. 

The service manager was keen to understand situation and five incidents in one year was accepted as cause for concern.  They will report it to Audi UK and that I could do the same.  He thought 10 such reports would generate proper investigation and action by Audi.  Other affected owners should do the same.  Isolated reports would be unlikely to prompt any action. 

By the way I think that where there are two or more drivers of a car then there would potentially be two “driving styles”, two reportable incidents and a very strong case.

Hello,

interesting , information I’ve just booked my Q2 into Cardiff Audi to check out the car the date they gave me was Dec 9 , I shall continue to monitor the instances and try to record what exactly happens with regards to “ certain conditions being met/ not met.

We’re both dealing with Cardiff Audi then.  
A “new” development or at least one I only noticed for the first time on the way back from Cardiff Audi.  When changing gear in 1st, 2nd or 3rd the “Gear Shift Indicator” on the dash would flash >N (neutral) as the gear lever passes neutral up or down between 1, 2 or 3.  That happened even though there was no hesitation and the change was smoothly carried out at a normal speed of operation. 
Used car today for first time since.  Drove almost 20 miles to Raglan Garden Centre and it didn’t happen at all until we had a mile or two to go.  Happened on and off on the way home.  After getting back unloaded car and then test drove around Blaenau Gwent for 20 minutes.  It happened quite often but not always.  Most often when changing from 3rd to 2nd at junctions. 
Have you noticed anything like that?
Worth reading about gear shift indicator on P.23 of manual.  Briefly if >N shows and you use neutral and release clutch the engine switches off.  So is this something to do with the problem we have?

Hello

to answer your question about the N indicator in the left display I haven’t witnessed this occurring but like I said will try and observe what’s happening,when the engine stops,it hasn’t manifested itself for a few days but will update you soon.

regards

Mark

 

[Oldnuff]

Update.  Still none the wiser. However I’ve raised it with Audi Uk and expect a reply within 2 days.  Audi Cardiff say they have had no one else reporting anything similar (engine cut-out).  Do you think now would be a good time to raise your experience?   Dylan Davies is the manager dealing with it.

I’ve told them there is someone else with the same issue but not said who or where.

[Oldnuff]

Good.  Hope they sort it or at least come up with an answer.

Hello 

I bought my Q2 two months ago now. It had a previous owner before myself. I have also experienced the engine cutting out on multiple occassions and also have experienced the rolling of the car onto a roundabout too. Most occasions have occurred after being in 2nd gear but today it happened when I was in 1st , went to neutral , but the lights quickly changed to green so I tried to move to 1st quickly and it had cut out. I started to put this down to driver style and that this car can’t handle being in 2nd gear when slowing down for as long as my previous car could but now I’m doubting that logic after todays experience 

[Oldnuff]

Sounds familiar.  How old is your car?  There were recognised problems allegedly solved with a software update in 2018/2019.  

[Oldnuff]

Audi carrying out a further “independent” assessment of my Q2 using a different engineer.  Also at Cardiff Audi on 9th December.  
No “cut out” instances since last report. 
I’ve mentioned the gear shift indicator to them and a very faint electronic hum that fades in and out.  Neither of these are issues I’m worried about and just wondered if they are linked.
