Coolant temp sensor

[TDIRyan]

I just want to confirm that I'm getting the right parts here. I need a coolant temp sensor and probably will get a set of glowplugs. I have 87K on mine, and they are original plugs and I have an intermittent signal on the #1 plug and the coolant sensor.

Is this the correct temp sensor:

How often should you replace the glowplugs?

yep, that's the right one. However, paying $30 for it is a rip-off.

I paid $15 at the dealership with o-ring

www.tdiparts.com has it for $14 with o-ring, plus shipping.

in the 254k kms I have replaced one glowplug

I may have a loose main ground wire, so I'm going to tighten up that this weekend, clear the codes, and see if it comes back after that.
