Hi,
got an issue with my GTI. On starting the car, there is a MFD error' stop start system'
so booked into my local (aberdeen) dealer only to be told the system does not work below 7degrees and if I book it in and nothing is wrong I will be charge £50 diagnostic fee. I just about blew up! 3rd GTI I have had and very rarely have I been in with warranty issues or the like. Extremely disappointed with the customer service. Car now booked in via another person on the service desk but I will be complaining about this to specialist cars Aberdeen.
also have a really annoying rattle (worse in sport mode) under acceleration. believe it is coming from the glasses compartment mounted up near the map reading lights. Also squeak/squeal from the suspension under low speed maneuvers.. so far not so good on the mk7 (had a mk5 and mk6) other than that it's a nice car.

If the stop/start is not working due to a condition (temp to low /power draw from other items that are on) you normally get the Circle A symbol with a line through it.
If the system is reporting an error then I would guess that it is an actual problem?
-
If your seeing an MFD error then there is no way they should be charging you any fee as it should be covered under your warranty
-
The car should not report an error on the MFD if the only reason for stop-start not working is the ambient temperature.
There will be a number of criteria that need to be satisfied (including ambient temperature) for stop-start to engage, the ECU makes this determination every time you stop and is not an error. If the MFD is reporting an error this would suggest that one of the sensors used for stop-start is not working or has received a transient out-of-range value...
-
yep, that's my thoughts Corgi. I have other cars with these systems and know that it won't go on if it's cold, not enough battery reserve etc. I was just shocked at the service actually... speaking to me like I was stupid and then threatening me about a cost implication if I actually took the car in and there was nothing 'actually' wrong!

If you look in 'Car' / 'Vehicle status' and push the 'stop start' button on the main display screen you can see a list of the conditions that are preventing stop start from working (or confirmation that it is currently available).
There are quite a few things that can stop it working, like 'windscreen may become misted'. The most bizarre one I've seen is 'Ignition not on' or something similar. 1) The ignition was on at the time 2) If it wasn't on, why would you be wanting to stop start anyway?
-
nope.. if I push vehicle status, it has a graphic highlighting the engine and saying ERROR stop start system.

Hi Lockhart,
I'd stand your ground with the dealer.
I had sat nav trouble in my MK5 GTI about 7 years ago and took it to VW Leeds. It was going mental and constantly rebooting like a PC. The chap on the service desk said the disc had expired to which I replied - "I've never heard of that before". Went away, researched it and nothing about discs expiring. Phoned him back, told him my findings and in an arrogant tone was told to wind my neck in as it was his profession and not mine (not exact words, but along those lines). Anyway a few months later I was over in Warrington and had it in for a service there and asked them to look at the unit. Within 2 hours I got a call to say the unit was faulty and they'd order a new one asap.
They're probably just looking at the first thing their diagnostics manual is telling them and hoping that's what it is - stop start doesn't work below a certain temp.
-
suppose its not clear on my first post... the car has not gone in.. this complaint was just to get the dam thing looked at!

If you're still getting that error even after you come back to the car for a new journey then get it booked in with your dealer.
Don't let them fob you off that its just not met its conditions for it to auto stop start. If it hasn't met the conditions you just get the little A with a line through it as mentioned above, this is just a little notification.
An ERROR is indicating that there is a problem, you wouldn't get an error if its too cold to auto stop start, you'd just get the little A with a line through it as a notification.
If you're still suffering the problem I'd get a photograph or two of the error you're getting displayed and then get it booked in, so you have the proof it was happening even if it "magically resolves itself" at the dealership. Don't let them fob you off, awful customer service that they just said that.

I have rarely driven my GTi in temperatures over 7°C since I had it in November. In fact much of my driving is at below zero at this time of year.
The stop start system works after about 5 minutes driving when the oil temperature is approaching 85/90°...
-
its booked in... so will report back on the issue. It was the customer service that pissed me off!
-
Surprised that the GTI holds off for a long while on warm-up before start-stop kicks in, it's available on my GTD pretty much from 1/2 a mile down the road. I suspect that as soon as the car is warm enough not to need glow-plug assistance to restart the stop-start is allowed.
Maybe there's a worry that the spark plugs on the GTI would otherwise coke up quickly if it pretty much has to get to full operating temp for stop-start to be available.

If you haven't already, check out the "suspension squeak" thread - if your noise is from the front it's more than likely the self same problem that many of us have already experienced and the fix is now well understood and documented. (Rubbish that's it's still happening though).
Having spent some time trying to figure out the stop start system myself I'd totally agree that there's absolutely no way that error message is normal.
Hope they get it all put right for you quickly :smiley:

The conditions for the Stop/Start to work are as follows.
The vehicle is stationary (speed = 0km/h).
The engine speed is below 1200rpm
The coolant temperature is between 25°C and 100°C.
The brake vacuum is more than 550mbar
The energy required to restart the engine that was calculated before “engine off” can be supplied
by the battery (starting voltage prediction).
The battery temperature is greater or equal to -1°C and less than 55°C.
The air-conditioning requirement of the occupants is not too high.
The difference between target and actual vent temperature is below 8°C.
The diesel particulate filter is not in regeneration mode (diesel engines only).
All of these conditions must be met for the car to start. External temperature is not used so tell the VW tech he is smoking his socks.

lockhart, did you hear anything back with this. On 2 totally random occasions over the last 2 months or so ive got this. Dunno if you got this but I start up then hear a crunch from the engine and the error start stop message comes up. I turn it off then back on again and its gone and all working fine again :S
-
Sounds like the first person was administrative and pushing out the standard response to 'normal' times when start/stop is not operating due to conditions.
MFD is displaying an Error! so would have just booked it as thought the person warning me over potential costs had no idea what talking about.
-
I too have had the MFD Start Stop Error appear in the last Month. Local dealer have looked at it and have ordered a replacement sensor. Im awaiting a call to have it fitted
-
I get the stop start non operational symbol sometimes, and when I check why it says engine must be running for stop start :rolleyes: Um it is!!
-
If it doesnt work under 7c then its fairly useless technology in the UK!
-
I don't think that is a limitation on the Golf... mine certainly worked at temperatures lower than 7C...
On the BMW123d I had stop-start would only work if the external temperature was >= 4C...The first two months I had that car I didn't know if the stop-start worked that was November-December 2010... when the daytime temp barely rose above 0C...
-
I've had this 3 times in total but more worrying 2 times today. This is about an error I know a lot on here are talking about when it won't work but this is about an actual error. I would scan with vcds but restarting the car fixes it. Please let me know what the dealers says as I know mine will probably blame it on my exhaust somehow so I'm not even gonna waste my breath until I see an error report
