As a long time VW diesel owner, I've changed my share of glow plugs on both
IDI and TDI engines. They will generally last 10 years or more if not run
too long, The older (80s vintage) 1.6 IDI diesel on Callisto has a manual
button for the glow plugs, and I will try to avoid using more than 5
second
For what it's worth -- another data point on glow plugs. I had a 2003 VW Golf
TDI 1.9L (Turbo Direct Injection) and drove it 200k miles. The glow plugs had
to be replaced at 80k and 160k. A good reading was 1 ohm. The plugs all went
together both times (probably) and the car was very difficu
