Seat Leon CR 1.6TDi - Start/Stop

[Hockey Guy]

Evening all!

Been having a few issues recently with my SE Copa 1.6CR. The start/stop system appears to have... well.. stopped lol

Every time now when I pull up to lights, put the car into neutral and apply the handbrake and release the pedals, I get the "A" disabled icon on the MFD.

It's been doing it intermittently since I had the car from new (about 4 weeks ago) but I thought it was because it would only work under certain conditions.

Can anyone shed any light on this subject? Or is it a "back to the dealers" jobby.

Cheers,
Tom

hey mate i was only thinking about you and your leon earlier today and i wanted to inbox you ans ask how the car was going and how you were finding the stop/start. You have answered my question already lol.

Hope you get it fixed ring your dealer where you had it from and they should get it fixed under warranty..... (i say that) let me know how you get on

also aprt from that prob how is the rest of the car?? Not long to go now untill i get mine and im still like a big kid cannot wait to get it now

The car is fantastic apart from this little mishap. The gadgets are great and the economy is getting better week by week. Don't expect mega figures from the get-go, as I'm averaging around 50MPG since new and that's with driving VERY conservatively.

One of the best features is definitely the Bluetooth music streaming. Though there's not much on it which doesn't impress

Hang tight, it will make the day you get it all the better!

thanks tom i'm now even more excited lol, i cant remember have you got the manual or DSG box??

i'm driving my mum nan and best mates up the wall by counting down every week lol, i can imagine how good the gadgets are with the car... and thats immense for a car only 4 weeks old for the MPG, what driving do you do if you dont mind me asking??

 

[Hockey Guy]

It's a manual box. I did toy with getting a DSG but it was a bit pricier and also it was thirstier.

I tend to do mostly urban driving with some country runs. The advantage with my commutes is that there are a lot of downhill runs so I can let the car roll where it uses no fuel, so the average can climb up to anything approaching 70MPG. The bad part is that when I come home, I have to go uphill and then MPG drops lol

I did a motoroway run the other week and was getting around 60mpg whilst doing around 65mph.

It's definitely a car that rewards careful sensible driving

Has the stop start stopped working when not quite warmed up, or early in journey's?

I didn't think it worked then.... or when it's cold or when the AC has been on loads draining the battery

That's what I thought it was, that the engine had to be warmed up. It's not doing it when I reach the end of my journey which is typically when I hit traffic and the car is completely warmed through.

Economical diesels take ages to properly warm up.

Mine works just fine. sometimes I wondered why it disabled the start/stop, I then took my head out of my arse and realized it was because the AC was on

The following reasons the start stop might not engage are:

Engine isn't warm enough
Your car is trying to do a DPF regen
You've got AC on. (Mine has done this one or two times I think, but not certain)
You've got the blowers on the front window
You're heating the rear window
You're on a steep incline (I've not witnessed this one myself but it's supposed to happen).
When parking or moving short distances using clutch control (I.E Parking, because you spend so much time on and off the bite, it doesn't bother).

Any of those situations where you've noticed it not working.

Also, I don't know if you know this, you don't need the handbrake for start stop to work As long as the car is in neutral and you're stopped, it'll work.

Had mine for two weeks. And sometimes start/stop even works when the engine is not fully warmed up (according to the temp gauge anyway, it was sitting at about 65c)

Quite rarely it doesn't work when it's warmed up though. But it does happen. I thought it could be the air cond. But even if air cond is on, it still works most of the time. The only time it wouldn't work for sure is when you move your gear to neutral from reverse =p.

Just read that the car has to be off for 30-40 seconds to start receiving the fuel efficiency benefit it was designed for. So basically the majority of the time, I'm wasting more fuel using the fuel saving system lol

 

[tdi_chris]

I have a 1.2 tsi with the start/stop system and the first thing I do when I get in the car is turn it off! I dont believe it saves fuel unless you are stopped for a considerable amount of time and I don't know if this is just my thinking but on a turbo car having the engine just stop immediately after pulling up is going to cause more wear to the turbo???
I also noticed that after using start/stop and not using it on the same journey my range computer was 5 miles worse with start/stop

Highlighted the above point - On my way to work today I noticed that the AC wasn't on, but I have had the blower on the front window switched on for a few days due to it steaming up. Switched it off today and hey presto, it works!

I note the comments made about the benefit of the system. I agree that it needs to be off for a considerable amount of time to make sense, but my approach was that it "all adds up". I think I will try a tank's worth of diesel with the system off and see if I notice any differences.

Tom

To be honest mate, I've read so many different articles claiming about how long you need to be at lights, it's ridiculous to know which one is actually true. So far I've seen 2 seconds, 7 seconds, 10 seconds, 15 seconds and 30 seconds, so it's impossible to tell which is right.

You're welcome

You're welcome

Pg 192 of the 2012 owners manual states "it is worth switching off the engine when waiting in a traffic jam, at level crossings or at traffic lights with a long red phase. The fuel saved after only 30-40 seconds is greater than the amount of fuel needed to restart the engine"

I guess it's personal preference tbh. I'll be having mine off from now on.
