Hi people, my cupra r has struggled to start when cold, or after its been sat for a couple of hours for a couple of weeks now and its not getting any better!! When the car is started in the morning for work, I turn the key and it just turns over trying to catch, i then turn the key for the second time, it tries to catch a bit more but just judders and missfires fairly badly, then i turn the key for the 3rd time and it starts no problem?!! Every morning it does this and when i finish from work.
When the car is up to temperature, and i start it after roughly half hour, it starts perfectly!
I changed the coilpacks with genuine ones about 8k ago and they seem fine, serviced the car yesterday with iridium spark plugs in hope that it could be worn plugs, but no different!
Coolant temp sensor replaced a few weeks ago too and no difference.
Stumped ! Im hoping there will be somebody on here to point me in the right direction, the car is also stage 2 modified with a custom-code stage 2 map, any advice is much appreciated,
Thanks, Michael
