We see a steady stream of Volkswagen TDIs with similar problems — low power, smoke, or that dreaded check-engine light.
If that sounds familiar, your turbocharger may be on its way out, and catching it early can prevent expensive DPF damage.
Why It Happens
Turbo wear is common in Jetta, Passat, and Golf TDIs, especially as mileage climbs. Missed oil changes, the wrong oil, or even small boost leaks can shorten turbo life and lead to loss of performance.
What to Look For
-
Noticeable lag or loss of power
-
Whining or rattling under the hood
-
Excess smoke (blue or black)
-
Check-engine or DPF warning lights
