Has anyone had experience with NGK glow plugs in the 2.4 JTdm? Our car has started to display the "glow plug pre heating unavailable" message off and on lately, so I might need to replace the glow plugs. The car has done around 73,00 km and I assume the plugs are the originals. How long do they normally last? NGKs are a fair bit cheaper than Bosch. I was quoted $52 each for Bosch at Repco, (ouch!), and $20 each for NGK at Autobarn. I can get the Bosch ones from the UK for $100 less than Repco's price, but if the NGKs are just as good I will do business with Autobarn.
The part numbers are:
Bosch 0 250 203 001
NGK YE07
I think Alfa recommends the NGK's as per service manual. Just download a manual if you dont have one and check which spark plugs you have to use. My Mito is using NGK's platinum. Not cheap either...
You may not need to replace all the plugs. I bought a full set, but so far only replaced a single faulty one (high resistance from the electrode to earth). Haven't had to replace another - that's at 120,00km+.
Does the warning tend to come and go a bit to begin with? It didn't come up tonight when I went to the club meeting for example, but does first thing in the morning I think. The other thing I am wondering is, if the battery is a bit suspect can that cause it? What brand did you buy Evan?
Yep, it came and went I guess the glow cycle doesn't happen when it's warmer? I bought a set of Bosch from alfaworkshop.co.uk.
