Hello

Audi A2 1.4 TDI 75
Started 1 year ago
When started cold no problem but on the road when bellow 70C' temp. and over 2k raves car used to loose power and go on 2 cylinders
lights comes on - warning symbol + beep + ABS & Traction control lights see picture
Normaly i stop turn off on starts ok drives ok up to 2k raves but when engine temperature reaches 70c' or goes abowe no problems at all can go above 2k
1 month ago everything is changed
Starting cold starts on 2 cylinders after reaching 70c' engine of on again no problems at all drives good
Scaned and is came with fault code on the #1 injector.
Before i go work i start car for 10-15 min then turn of on again and drive without problems as temp. goes above 70c'
I was thinking about injector loom harness, maybe this coses problem but not shore

Any advice please

One more thing ifound out yesturday - got back home after good few hours decided to go out turned key engine temp was bellow 70c' started fine after runing for 30 seconds got back to 2 cylinders, after temperature went above 70c' i turned of on again back to 3 cylinders
Strange why it is started fine maybe warm fluid inside engine made it start fine maybe kind a sensor picking warm cold temp and doing this?

Any ideas/advices?
 
Perhaps as the engine warms and cools the injector seals work or fail or the spray burns better? The loom making contact or not.
 
Ok guys done

It was injectors harness i paid 10£ for used one now works as it has to
took me about 45min 1hr max
+30 minutes oil, oil filter change
It is easy removed air intake tube, then took off lid changed harness, old gasket to new one
job done
i used only one key and scre driver + star to remove air intake :) i tought will require more so prepared but no needed
