Hmm - with the car in Economy (Efficiency) mode, when you throttle off the car goes into coast mode effectively putting the gearbox into neutral allowing the car to free wheel at what should be tick over engine speed. With the gearbox in neutral there is no drive back through the geartrain from the wheels to maintain engine idle. This could be where the issue sits. If it were me with the Audi overalls on I would be looking at sensors and settings around engine idle control. The next question would be does the fault happen in Auto drive mode? I tried all drive modes when I first got mine and it sits in Auto Drive Select most of the time now with no perceivable difference in economy. I concede this is not a fix but could be a work around of sorts

Hi Jenny: As you can see - no-one has really come back to the forum with any information / progress regarding this possible issue with their car. When the engine cuts out (stalling is caused by overloading) can you recall what you were doing regarding controls input. Throttle on / throttle off. Braking? I see you have your drive selector in economy - is this always the case or just in the picture? Mine will stop its engine coasting up to stopped traffic but not above 10MPH. When it cuts out does the rev counter go to "ready" or "off"? If we can find a common factor when the issue occurs this will be of use to any mechanic trying to diagnose the issue. My best advice is to keep on to Audi regarding the matter - you are approaching the end of normal warranty for the Car - this should be sorted as part of that original manufacturers cover.

Like with everything electric and intermittent I would first investigate connectors and cables. In all road conditions we drive our cars expecting everything to be shock, water, heat and cold proof. Also look for the A7 thread on here regarding the gearbox fault. Coolant Leak into loom from sensor in this case but a little damp soon makes a big problem. I would clean - dress and reafirm all electrical connections before looking at hardware.

Never be sorry for what is valuable information. Lets hope Audi Techs have the sense to read some of these forums. Used to get it a lot with VX where I would take a car in with an obvious fault - intercooler hose for instance - but they would insist on putting the diagnostics on for a fee first. Trouble is Main Dealer Techs are Technicians programmed to find the immediate issue through fault code readers. This identifies the fault but in many instances not the root cause.

LED bulbs have a different impedance than original filament items. Bulb fail detection works on impedance differential on the circuits. You would need LED units with build in resistors or add resistors to your existing items so that the warning will go out or I believe you can turn of the bulb fail detection in the ECU - depends what the path of least resistance is with you (pun intended)

Sounds like primary power issue to me - battery is new so that can be dismissed. Some Q7 have reported power grounding issues - check earthing straps. If your central locking works then that would suggest power is good and primary functions are working. Do you have both keys? Same issue with both? As asked above - does radio come on without ignition on?

I had the option of 10K and 20K (extended) service intervals. Due to the milage I do a year I opted for 20k. Some say service every 10k as Oil is critical but modern oils tend to be better with age. One area where oil is impacted is on the number of regen / failed regen your car may do. It is thought that engine oil can become diluted with diesel when a regen is interrupted. I have tried to read up more on this theory but there is so much conflicting opinion that I am going with my own thoughts and those of VAG - if 20k were a problem they would not offer it... Sounds like the car you are looking at is on or below average miles and will have been on extended service. I see you are listed as in london - lots of city driving? if so I would err back to the 10k interval but that is only me...

Hi - I have a 16 plate A6 with MMi and I use an iPhone 6 I have not seen any of these issues but can make the following suggestions - The Software between the iPhone and MMi have become incompatible due to an update in either or software releases? The playback on the iPhone is set to preview? Sorry I cant be of further assistance but I do know that your iOS is later release than your MMi OS

I have heard that the next gen Hybrids will be 48VDC -

RTFM?

White milky fluid in fuel system sounds more like water contamination. Had this on an old VX soon after I filled up at Sainsburys. Contacted them and sent them the claim - they repaid the bill but it was more obvious that they were at fault as they had a few claims hit them at the same Forecourt on the same day. Free water in diesel will drop to the bottom of the tank immediately so I would expect the damage you have experienced to be from your last fill up. Any garage would not appreciate you turning up with the parts and be asking for labour only. Have you sought the advice of a diesel specialist? http://avon-motors.co.uk/ Audi are steep on labour but I would also look at a full fuel flush if possible before going down the road of system replacement.
