I bit of help needed if possible
My tiguan is hard to start on cold mornings just cranking not firing changed glow plugs fuel filter and its still the same.
Rund fine when started no compression issues,is there anything I have missed before I throw the towel in.. thanks in advance..

Is there a control module for the glow plugs?

I had similar issues with my Jeep Grande Cherokee. New controller and all was good.

No sure about control module though some folks have told me to change the temperature sensor?

It could be the engine coolant temperature (ECT) sensor.
I assume you have carried out a scan to se if there are any fault codes stored?

I havent yet but thank for the heads up
