1. Coil failed on #1 cyl. Normal item on these engines
for those year
2. As things usually go
, two days after, HiD bulb dies on same car.
Quality VW components
Yeah, they are. Toyota uses exactly same components from same manufacturer. Except, changing coil in VW takes 5min, on Toyota takes 4hrs.
Quality components that fail? Right! So, VW is using Denso ignition coils? I thought they were using Bosch.
I have never had a coil fail on ANY vehicle that I have EVER owned. There isn't any need to worry about how difficult it is to replace a component that doesn't fail.
VW uses NGK. But I can see not failing on Toyota. Part of the reason why it fails on EA888 is that engines run hot (NGK provided different coils since 2012). It is bad bcs component like coil will fail. It is good, since Sienna is not drivable in cold weather, unless it was on block heater, so we take VW, just so that kids do not get pneumonia.
As for worry, yes there is, as Toyota requires spark plug change, which of course on Toyota V6 transverse mounted engine equals nightmare.
As for HiD, Sienna has those two candles in front which provide amount of light eqal to two AAA batteries, so yeah, there is no worry for HiD failure.
