Hello everybody. Here is the problem. Yesterday morning I cranked my 2.8L Diesel Jeep Liberty 2007 and the ETC lightning light popped up. I called the dealer and a mechanic told me to let it warm up, shut it off and crank it back and see what happens... That's what I did and the ETC didn't come back up. In the afternoon I had it checked with the OBDII and the computer reported a faulty GLOW PLUG at cylinder 4. The dealer told me that it is out of warranty (go figure) and that the cost of the glow plug is around 100$ + VAT (133 euros) + work, so around 200$ in total + VAT (220 euros). What?
I checked over the web and I found out that the cost of a glow plug is about 20 euros, and that would be for the best glow plug that I can find. Now the question is... What if I buy a glow plug and I replace it myself or ask another mechanic (not a Jeep Dealer) to do it? I read somewhere that there could be voltage issues, would this happen with a glow plug of an higher voltage as well? (for example I put a 11V glow plug in substitution of a 5 or 7V). Thank you all!
