Loss of power TDi dropped to 50mph

stevehaz_uk · 11-02-2007, 18:37

Driving down the motorway at 75mph my engine suddenly lost power dropped to 50 mph - foot to the floor would not pick up. After 2 miles it picked up again and felt Ok but not as powerful as it should. Next day when cold the car started first time but appeared to rev itself - seemed OK when warmed up, but again a little jerky. May not be related but my temperature guage has been going up and down for a while, but normally returns to normal. Any thoughts?

Quite a few, need some diagnostics done to pull up fault codes,

Possible

Sticky turbo
Coolant temp sensor
Air mass meter.
