Reasons why the glow plug light comes on in a Volkswagen engine
Model: Volkswagen Polo
Polo 5, Polo V, MK 5, MK V, 6R
- Years 2009-2017
In this video we can see what to do when the glow plug light comes on in a Volkswagen engine; usually the vehicle becomes very weak at this point. Naturally, as it is a workshop, the diagnosis is done with professional equipment and the error can lead to three different interpretations: problems with the variable geometry; a broken sleeve or a blocked turbine. We clear the error and set values to check during the road test, which excludes problems with the variable geometry. The evidence is a leak, which can only be verified with a specific tool that shows two leaks and we see a sleeve with a large vertical cut. Unfortunately, even though it is a minor replacement, to get there you have to dismantle quite a few pieces, but we have found the fault.
