Limp on a morning

[Lodgey180]

Had this problem all winter
when i start my lcr up in the morning it starts fine and ticks over smooth. when i go to put my foot down once its warmed up it is in limp mode?
after i turn it off and back on its fine?
changed temp sensor and also changed my spark plugs back to standard ones as i thought the denso iridium plugs where to cold but it still does it.

any ideas ?

HMM better get the vagcom out.
it only started when i put the denso's in but now i swapped them back it still does it.

Hi guys any lights on the speedo clocks at all..? EPC? it could be the accelerator pedal position switch, i think i can slighty remember my brothers cupra started doing it, then his epc light came on and it was one of the swtiches underneather the pedals.

hope it helps!

Mines the same and has been since december!

As you say turn the ignition off and back on and its fine full boost is back!

Vagcom always gives 17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!). I have service the DV checked and replaced hoses but still does it! Now im just used to starting the car driving for afew minutes then turning off and back on again but would like to sort it out if i could!

not a safety feature? when cold?

if your cars have been mapped then the IAT values in the map need changing thats all

IAT stands for inlet air temp

mine only started doing it after a local tuner re-loaded the re map to cure a hesitation problem... going to get a custom re map done in the spring so will see if that cures it.

Have you checked small pipes under inlet manifold? Check my rr thread. I had those for months.

I've done all my vac pipes.........

 

[Lodgey180]

Ahhh maybe IAT
mine also shows the vacum drop for turbo to inlet
just figured it was from when i blew my intercooler hose off in the past
Will contact my mapper and ask the question

Sorted! As said above, had a stage 2 remap done the other day and told the mapper about the problem and he said the IAT value just needed adjusting. Car is now fine, full power all the way!

my cars got the same issue

 

[willpr]

Are the IAT valves something that can be done at home or is it something a mapper has to sort. Santa pod at week end and I have same problem

 

[RS6]

whos your map with?

 

[Yaboy]

i got an elite remap
