Could anyone suggest approach to investigating my issues?

 

TDI DSG started to hesitate from cold, particularly noticeable up hills, even small inclines.

 

Temp gauge seems slow to warm up too, so suspecting could be thermostat issue?

 

Car once running warm seems better and all ok on the flat!!!

Was thinking Coil Packs, dirty EGR and so on too. No warning lights though.

 

Any ideas would be most appreciated.

 

Thank you.

Coil packs in a TDI?
What engine do you have?

I suspect I don’t have Coil Packs, but the issue I have is quite like an issue I had before but that was on a petrol car!

 

TDI 140 2014 

Simple stuff first.

?

How many miles covered?

When was it last serviced, when was the air filter checked or changed, when was the Fuel Filter replaced?

 

 

If it only happens when cold that would point to a glowplug issue.

Reluctance to start yes, but misfiring driving up a hill will not be a result of a glowplug failure/problem.

 

I'm sorry that I dont have a solution to your problem Flatjack but I can tell you what it isn't!

Thanks everyone for feedback ahead, sorry for slow response.

 

The car was services in April and its done around 3000 miles since.

 

The other issue to note is that it is very very slow getting warm, and can take 30 minutes for the temp gauge to move.

 

Could a faulty DSG Thermostat cause this and the original stuttering issues from cold?
