Title: Golf MK4 2.0 Cutting Out
Post by: Jakg on 10 April 2016, 22:18

My girlfriends got a MK4 Golf GTI 2.0 but has had some problems recently.

It kept starting to cut out while driving, but then coming back to life displaying the "emissions workshop" message. Eventually it cut out and would not restart.

I go and give her a tow home, bring it home and use the starter to bring it onto the drive and it fires up into life - weird.

Took it for a quick spin an hour later, all seemed normal, ran ok. Left it idling for 5 mins and then it cut out. This happened a few times.

Idles ok when running, but it does smell a bit... exhaust fumey for want of a better word.

When cranking the tacho always moves which suggests the crankshaft sensor is ok?

Plugged in my ScanGauge but it couldn't detect any faults.

Thoughts on a postcard - otherwise it's going to the garage on Tuesday.

Exhaust leaking?

Use a proper VAG software for fault codes etc. OBD2 won't work.

Unplug the MAF see how it runs. Always replace for genuine oem MAF

Garage took a look and cleaned the throttle body, didn't fix it and they were a bit stuck.

I bought a VAGCOM and it turned out to be the crankshaft sensor. Fitted this morning and it hasn't cut out yet. Fingers crossed.
