Anybody had this one in a 1.4 TDI before?
About a week ago, accelerating up a hill the car suffered a loss of power (one minute it was pulling hard - next it was struggling up the hill). Car was like this for the whole journey to work - no power on wide throttle openings but ok on a gentle throttle. By the time I got to work I had convinced myself the mass airflow sensor had failed.
Lunchtime I start it up and it's back to normal (and continues to run normally for over a week and 500+ miles)!!
This morning the same thing happens - dramatic drop off in power going up a hill with a reasonably wide throttle opening. This time I stop, turn off the engine and restart - and it's back to normal immediately (and has been for the rest of the day).
No warning lights are lit. Mechanic was inclined to same view as me - MAF sensor - but he reckons these either work or they don't - not likely to fail intermittently.
Ideas appreciated??
