HI everybody! Im from Argentina and its a pleassure to share a forum with you, i`ve been reading since i bought my Leon FR 2.0tfsi 2007. I know some english, so i will try the best to understand me.
The car is chipped witch 3`downpipe and CAI. The power is about 260bhp.
The problem
2 weeks ago my car started to do a jerking phenomenon during HIGH acceleration (sometimes little explosions too). This not always happens, only sometimes and mostly in middle RPM (mainly between 3000-5000 rpm).
If i accelerate slowly nothing happen, so this only happen when i pull hard the accelerator.
My mechanic changed the fuel filter, check cylinder pressure, turbo and everything seems fine. Also i put fuel from another company and always the high octane one.
I connected with VAGCOM and the engine hasnt any error! if this should be a ignition problem like plugs or coil packs.. Can the computer not generate fault codes, like mystfire o something else??
I can record with a camera what it do or maybe do a Graph with VAGCOM (with the variables you tell me), i dont know..
Any suggestion?
