Hello! II would ask for some help on the diagnosis of my 2014 Golf 7 2.0 GTI. Symptoms include the car is hesitant to start when the engine is hot. It will start perfectly fine on a cold start, but if I turn it off after it’s warm then try to turn it back on, the starter will keep trying but the engine won’t start. This will throw a p2188 code(system too rich at idle). I’ll eventually have to give it some throttle for it to fully crank over. If anyone has any insight on this I would greatly appreciate it! Thanks
It's a possibility. What values is it showing on the diagnostic? I presume you have a clean air filter? Might be worth looking at the values from the airflow meter, if there's one in it. I'm not very familiar with those engines.
I didn't check, but I searched the internet and some people said it could be this ... I'll look tomorrow and I'll take a picture with what values I have
I have a clean air filter, but I don't think that's because it only causes problems when the engine warms up ...
Is this a belt deiven engine or a timing chain ? If chain then it might be either stretched or chain guides worn trough. I suggest you take some compression readings and check the crank/speed sensor on a scope to see what signals you might get. I believe you either have chain stretch or low compression issues, I suggest you take it to a competent Mecanic/vag specialist and let him run diagnostics !
Did you find any foreign bits in the oil at recent services ? Plastic bits I mean, it would explain chain stretch however I would take it to an experienced mechanic for a few checks. Does the engine rattle on first start in the morning ?
