Hello I hope this message reaches you all in good health. Firstly like to thank you for having me and for your answers in advance.

 

I have a 2010 1.6 tdi estate octavia with 188k on the clock really nice to drive, fsh, one previous lady owner. 

 

So the problem I am having with the car is that the turbo is not working and neither is the cruise control....however whilst driving if I quickly turn the car off the on the turbo kicks in until I stop at a junction or traffic lights. 

 

This first happened when I got off motorway and the car lost power I simply turned the car off and turned it back on 5 seconds later and it was fine again. It then happened a few weeks later again I done the same and now few weeks later (2nights ago) its just not happening at all.

 

I have taken it to the mechanics who has kindly put the car on the ramp and inspected the pipes and said they are all fine and then connected the car to his computer to which there were no fault codes at all and no dash warning lights.

 

Somebody please help me as I need my car for work and it is extremely difficult to drive without turbo. The car is very slow to pick up speed in.

 

Thanks.

Criuise control can be dirty contacts. Can try to clean. Search on here or google golf / octavia cruise control switch cleaning.

 

Turbo i'm far from an expert on 1.6 diesel unit. No fault log is strange. Suggest a full scan with Vcds maybe worthwhile, not just a generic scanner.  

 

Could be an overboost issue but wpuld usually be accompanied by engine lights and fault codes...

Not sure about the 1.6, but on my 2.0 BKD the overboost protection doesn't trigger the engine warning light.

 

A VCDS scan shows it up clearly though. Sticky turbo vanes is the usual cause.
