Title: AGG engine cuts when warms up
Post by: triplemaya on 10 August 2015, 20:10

It is a Y reg golf avant garde so Mk 3.5

Cuts out once it gets fully warmed up and then go up a hill. Starts up fine as soon as it has cooled down a bit.

Standard AGG engine 2.0 injection.

Been in more than one garage.

Had new distributor, no help.

Supposedly had a new crank sensor just before I purchased 18 months ago.

Tearing hair out at this point.

Don't think so. Never noticed one. No blinking light on the dash. What should I look for?

When you say cut out, does it loose power or cut out completely?

If it looses power completely....
How does relay 30 look?
Check soldering spots, if they look cold reflow solder.

Thanks for helping.

It cuts dead. Sits dead til it has cooled off just a little. Then starts up a treat. Grr!

I will check the relay tomorrow.

and report back.

 Cheers.

Does it stay running if you keep the revs up?

Its the Crank Sensor. Replace that straight away.

I've seen new crank sensors fail within a matter of days. Cheap GSF copy crank sensors tend to last 1 year and a half.

I've experienced this fault before. Replace its with a Genuine one

Yep, I would scan it to be sure but patern sensors are pretty weak.

Thanks for all the input.

The whole problem was it showed no codes when it was in the garage.

Anyway, it may be easier to diagnose now. I put in a new relay. It cut out as soon as it warmed up, never done that before, and wont start at all now.

I always had a spare in the boot as they are now made of old  Chinese bicycles.
