Hi guys

First post around here.

Picked up a low mileage (11K) late 2013 petrol 1.2 TSI 105PS, fun car car to drive so far and not missing the grunt of the 1.8T petrol i had in the departed VW Bora.

Anyway im in the first week of driving it.

I notice when i first start from cold the revs will be higher around 1100 which i know is normal and expected with the secondary air pump running for like 90 seconds.

Seems a bit rough lumpy while this is going on, again yeah its not going to be really smooth but how rough is normal on these?

Also this morning it didn't kick in from cold and the revs stayed below 1000, nearer 800. Still a bit rough for a bit but i waited for a couple of minutes then drove off.

Should the air pump always run on first start with these engines?

 

Cheers

They don't have a secondary air pump.

If the revs were low when you started up - I suspect that you slightly planted your foot on the 'go pedal' when you started. This will normally negate the normal/ increased revs start procedure.

I have the 1.2 and it always starts slightly over 1k, runs for about 30s then dips to about 700-800ish idle. I believe thats normal. As 2ndskoda said, if you touch the accelerator when starting up it does behave slightly differently.

Hi guys, cheers for the replies.

Had the car for about 2 weeks now so getting used to what's normal, with this car anyway!

I think it's doing what these engines normally do but I guess they can all be slightly different.

I'm sure it has a secondary air pump as you can hear what's like a vacuum cleaner sound for a minute or so on first starting, then it clicks off and the revs drop down to normal and it's much smoother running. It's obviously a bit rougher when the pumps running,

I'm used to them as had one on the VW Bora.

It just seemed to be a bit rougher than I'm used too, but that was the 1.8T petrol so can't compare really.

Also I find from cold starting it fires after a few revolutions on the starter motor where I was used to the 1.8T firing up straight away every time for the last 7 years.

Good luck with finding your SAI pump.

Gonzini,

Has your car had a Minor and then a Major Service? 

Has the Air Filter been checked to see if it needs replaced, and if it has been replaced is it the correct one. and the air box sealed properly?

Must say that there is lots of hum, whir and clicking for a few seconds after the 1.2tsi cars are turned off. No idea what this is, I suspect the clicking may be the parking and/or calibration of the turbo electric actuator.

The aircon has a habit of turning itself on when you start, and that starts the cooling fan.

Sounds like it really doesn't have one then!

Weird as i can hear a familiar sound that they make and it behaves like the last car i had with one fitted, just a bit rougher idle.

There is, maybe I'll lift the bonnet and have a look.

I'll look into the aircon thing, good call

Gonzini,

I think its due in mid December going by a sticker on the door pillar but will check the service stamps as to what's been done so far. Its had 2 services to date being a late 2013 reg.

When i checked the service interval on the display its says 10K miles so i don't know if its on a long life service schedule.

I might just get it done anyway in December so i know were I'm at with it, the oil does look a bit darker than I'm used to seeing.

The guy at the dealers said it will tell me if it needs replacing early if it needs it as it checks the quality of the oil? Is that correct or is it not that clever?

If set on fixed servicing after a technician resets, or anyone else does the computer goes to 9,400 miles / 372 days till next service.

 

It can be on Variable / Flexible servicing and will tell you when the oil should be changed before about 19,000 miles, or at before or at 2 years.

So if on Flexible the oil should have been changed in 2015.

& that will show on the Skoda Computer system at the dealership if you ask, and if there is no service book or invoices.

 

Being 3 years old later this year the Brake Fluid is due a change.

 

Best get a service done and any warranty work needing done before the Warranty Expires.

Any Service Campaign work as well. and maybe at the service it will get a Software Update or any other enhancements.

James (post #2) can be relied on to know these things as he's a chief Skoda tech, and I have the impression that SAI hasn't been used in new cars/engines for quite a few years now, maybe 10+.  Extra catalytic converters very close to the engine (pre-cats or manicats) have made the SAI systems redundant AFAIK.

 

Not sure what's making the noise in your bay though.

Hi guys

Cheers for the replies.

l'll check the service history in a bit, it would of been done at main dealers so by the book I would hope.

Agree on the brake fluid change this year.

I've had a few silly things sorted this week, they where really good. Sparshatts in Botley.

I'm glad that the SAI pump has gone, it was a pain in arse when it played up on the 1.8T Bora.

Maybe l'll lift the hood before starting in the morning and have a better listen. I'm probably just getting myself at it.

One thing I have noticed the last couple of days when leaving work when the temperatures been up (engine cold..)

It does the normal higher revs thing for a while then at the end it drops down then kicks in again for a second then drops again.

Seems weird to do that but maybe it's normal behaviour?

Cheers
