New owner of 2006 VW Jetta TDI. Already replaced wastegate.
Code reader shows #2 glow plug. Reset once but back on next day.
It's only minus 30 celsius here today. Is this a glitch or should I be worried?
150,000 km. R & R 1 or all 4 plugs?
Replace that one but with that mileage it can't hurt to replace all 4. The glow plugs can break relatively easily so put some penetrating lubricant around the glow plug threads and let soak before trying to remove them.
