Good morning all.
This is my first post as a new member and was hoping the brains of this forum will be able to help me out.
I understand from reading posts over the last month or so that this idle engine judder is a common topic. I have however never seen a definitive answer/cure to this problem.
Thanks in advance....I know someone here can help as you seem to know almost every cure for every problem.
My story is as follows.....
My car: Audi A3 2.0Tfsi (57 plate).
Engine Type: BWA.
Symptoms: Well here we go........
.......Since buying the car 4 months ago, it has become to my attention that it is suffering from what I would describe as a slight engine judder (at idle only). Revs don't move in any erratic way, but they do move ever so slightly on occassions. When sat stationary I feel this little judder in the cabin of the car. The engine seems to wobble when looking under the bonnet. When driving the car it is smooth, seems very quick and how it should be.
I have so far.......
Changed spark plugs (NGK Platinum), cleaned the coils out as there was black deposits on all of the gold plates that touch the spark plugs.....went for a spin, sat idle and seemed ok......then returned after next journey.
Checked air filter (was dirty), but ran engine without filter inside the top cover to eliminate air flow blockage.......no change.
Check all visible air hoses for splits, sprayed them too with carb cleaner.....no change in idle note or revs.
Checked N80 purge valve is functioning properly (I can hear it clicking away).
I understand the PCV valve is faulty if the idle raises and lower erratically, and oil would be found around filler cap.....and there is not. Also on a visual, engine off and PCV is closed.
Problems I have encountered during ownership are as follows.....
Engine coolant sensor message on Display (just overfilled it by 1cm and no message for 2 months).
Had friend look at engine wobbling and he removed Oil filler cap whilst running (engine struggled but continued to run).
Had friend scan engine after and it had codes P0441 (Evap system), P3137 & P3138 (V157???)
Not sure if with him removing the oil cap it disrupted the engine vaccum of not and threw these codes.
I'm sorry for such a long post. I thought I'd be thorough and give all the details the best I could.
So.......get those brains working people..!
Can anyone help me solve this judder.??
Many many many thanks.
Rob
