Pcv sounds fine to me. Pulling the plug, the engine clearly start going rough but it stabilizes itself and increases the rpm. Thats normal. If the pcv was bad, you'd get misfires, running lean codes and the engine would tend to shake at idle, especially after starting.

On the other hand, if there's a vacuum leak, what will happen is the engine will stabilize itself after 2 minutes or so and then if you pull the dipstick or take the oil cap off, it will make no difference. This means there's a constant air leak in the system.

But yeah, if it hasn't been done, it's worth replacing. Another thing that went bad for me was the brake booster vacuum hose. The plastic hose that goes from the check valve to the vacuum pump cracked and created a constant leak.

The condenser is the usual culprit as it's the first to get all the stones and crap thrown at it.

You can take it off and blow into it.  Air should be flowing one way and not the other, via the valve.

Mk5 General Area / ECU/ECM Testing and Refurb

« Last post by TheBALDpuma on Yesterday at 10:02:06 am »

Hey,

My garage has narrowed down a fault I have with starting to being a suspected ECM issue, so wants to send it off to get tested/repaired.  He's just messaged saying the two places he usually uses have gone under so I thought I'd ask on here if anyone recommends a place to send ECMs??

Cheers

The corrugated plastic hoses also crack and become brittle (age and heat cycles).  I replaced both of mine due to cracks that I could not see......the two from the PCV.

Thanks for the info will check. Is it possible that a failing PCV wouldn't show anything on a smoke test though? as they reckoned everything was good with no apparent leaks.

Sounds like PCV to me as pulling the dip stick out would make the car almost stall and hate that it was even turned on.

Was it an original PCV as I once used an aftermarket one that failed within a year, put an original on and its been fine for much much longer since.

Hi yes it was a genuine PCV. I'm edging towards maybe changing the PCV & possibly DV aswell and see if that solves it.
