Cold starts ok. Drive down the road, slow down/pull up for junction (foot on clutch and brake) engine cuts out dead. Restarts fine, even bumps ok if still rolling. No fault codes.
EGR valve was faulty, valve stuck, diaphragm leaking and roller bearing broken. New VW part fitted. Also new fuel filter fitted. Throttle body removed, cleaned and refitted.
Fault is still exactly the same.
Any ideas???
