1,4 tsi stutter when cold

[Alsomme]

Hi

My 2010 1,4 tsi DSG  has started to have a slight judder/stutter when cold. 

The tacho jumps up and down by +- 100-200 rpms. 

It almost like it runs to low on rpm. 

 

It is a bit annoying and especially because it makes the drive a bit uncomfortable. 

Talked to the local dealer and they say it is because the engine is set up this way and normal. 

Emission etc. 

 

Any toughts or is it nothing to do about it. 

Feels worse when it is wet weather. 

When engine is warm its silky smooth

I'd start buy checking the spark plugs and coil packs.

Thanks for tip

Would a faulty coil pack trigger some available reading if i connected my car to a diagnostic tool?

Or must there be a fault triggered on my dashboard warning before any faults could be found. 

I was thinking of intermittend engine misfire. 

 

[Anddenton]

Yes, a VCDS scan would show up misfires and which cylinders were causing problems.

So have the 4 spark plugs been taken out yet and checked, and since out replaced yet?

 

Misfires do not always show as a fault code, there have to be enough in a cycle to log.

[Alsomme]

Replaced spark plugs. But still som stutter when cold. But intermittend and therefore my next step would be to check if there is misfire. And no fault triggered on my dashboard. But makes sense if there would be to few to trigger a log as you said

I am assuming that your air filter has been checked and is clean and dry.

 

So the fitted for life Fuel Filter can be replaced.  Some Techs do that at 4 years / 40,000 miles anyway.

 

Have you tried running Super Unleaded to see if a higher octane than 95 ron has it running any different when cold?

 

As it is what is cold, do you mean before the coolant is showing 90*oC or the oil is getting up to around 50*oc and higher, since you are having high ambient temps just now.

[Alsomme]

Changed air filter also today. It was in a sorry state. So will see if that have some impact. 

Before i go spending money on coil packs. 

The stutter is before the engine reaches normal running temp. 

Will check fuel filter change also

 

thanks for the inputs so far

[Alsomme]

Update. 

It was the clutch pack in the DSG that caused the stutter.

^^^?

Have the Clutch packs been replace now?

 

Was your DQ200 DSG part of the World Wide Recall or just the Service Campaign in Europe,

so the facory fill Synthetic Oil changed to Mineral and a Software update done sometime between 2013 & now?

No waiting for a price quote. 

I had the oil and software update. 

I also had the mechatronic changed under warrenty in 2014

But diagnostics confirmed the source of the problem. 

 

Will update thread after i had the job done

Clutch pack is now replaced and the car drives smoothly. No stutter at all. Like new. 

It’s now i realize how bad my clutch pack was. But i guess over time you dont notice the breakdown
