Hello everyone! I have been reading these forums for a while but this is my first post!
I have a 1.9TDI cupra which has been Remapped.
I am having a slight issue with limp mode, I have owned the car for 2 months and when in 6th gear on the motorway accelerating from 70 or 80 up a gradient the car goes into limp mode when I turn ignition off and start car the turbo comes back. No fault codes are thrown and so far I have:
Cleaned EGR with carb cleaner whilst running (can't get it off as there is a top strut brace I can't remove!)
Had every tank with either Redex or Vpower as I thought it might be injectors.
Have tried "italian tuning" up a big hill in third.
Next steps:
I am going to take off the bottom engine cover and check all the intercooler pipes and connections, I have tried a soapy water bubble test on all the connections I can see from above and as far as I can tell no leaks!
Log the boost vs RPM logs from VCDS as a graph to see if I am having any pressure surges.
If neither of these work then I will trying the mr muscle trick.
Anything else you guys would recommend testing/trying out?
I get a slight turbo wine in 1st and second gear at low revs (not there when revved in neutral) could the this and limp mode just be a sign my turbo is on its way out?
Thank you in advance! and apologies for the essay!
