I have an '01 GOLF TDI with 166,000kms, mostly highway (really!). Recently I have been experiencing a tremendous loss of power that only occurs intermitantly. For example, taking almost 1 km to get my speed up to 100km/h., or, not being able to go faster than 120km/h on a flat highway. Then the next day, everything is fine.
My dealership told me that my mass airflow sensor needs replacing ($542CDN for the part), yikes! I will get it fixed sometime soon but not able to do it this month. Anyone experienced this before? I love my TDI and plan on holding onto it for many years but I don't want to replace this part every 3 years. Any advice would be appreciated.
