Had a compression test but as PDT Dave said it needs to be more in depth testing to really make issues apparent  :sad1:

Do get a fluttery boost sound.  Am replacing the n75 valve as matter of course, when I take dipstick out the engine doesnt run like sh*t as expected, in fact there is no change in engine note or hunting....  :sad1:

What happens when you remove the oil cap with engine running?

no real fluttery boost sound on mine, more of a 'skip' motion when accelerating, did it on the way home today and definitely worst when in 4th or 5th gear, but flutter/judder/skip would sum it up

I had exact same problem recently, only happened about 2-3 times, randomly. Like you, seems to occur in higher gears, 3-4 or 4-5.

Changed spark plugs and seems ok at the moment. Spark plugs were very loose when I changed them.  :confused:

Also got cam follower change on the 'to do' list.

Hmmm interesting. Mine has been like this for nearly 2 weeks now and is wrecking the usual smooth ride. Certainly hope it isnt the spark plugs as they replaced those during service a mear 5 months back.

Short of changing  the N75 and the PCV plus hooking it up to a VAGcom im running out of ideas

Nope mine is completely standard as far as i am aware. VW changed mine (well they should do as part of main service - havent looked of course), in May and did the coil packs on the recall at the same time. Didnt have any problems the entire previous year since i bought.

Seat mech swapped plugs and on autobahn it still logged the fault.

Tried new coilpack, still logged logged fault on cyl3.

Fittin REV N PCV as matter of course this week.  My money is on injector & / or dirty valves not seating.  :sick:

I'm not having any faults logged... it just pulses in the higher revs.

Do our cars have vvt? Could it be a sensor for that? But surely that would log something?

Yes, I'm led to believe they do have vvt.

hi all,

been doing some more research and came across this thread.

It refers to similar items that we have been experiencing and looks at the PCV

After taking my engine cover off and looking at my PCV it has the same issue as in this thread, so a call into the VW stealer on Monday to find out how much the parts are.

However preparing myself for having to swap injector.  Also have a lambda sensor (Sensor 2, post cat) to replace.
