Another prob?
« on: 02 February 2007, 21:12:42 »
With my Merc this time......you'll be getting fed up with me soon  ::)

Ok its complaining of glow plug failure....warning light comes on after starting.....i know its good practice to change em all...i dont have a code reader for it so dont know which one it is complaining about?

Is there a way to measure the resistance of them....to identify the faulty one/s ??

Went into halfrauds today to buy a complete set....bout £40 ish.....but they dont have em for my merc  :(
and was told dealer only part......so not wanting to be shafted by merc dealer...id rather just find which one/s have failed and change em  :y

Prolly a question for the diesel omega owners?

Cheers

Try local motor factors - Halfords cannot expect Merc to have a monopoly on glow plugs surely  :-/ and put in a fresh set - no need to meddle with resistance then  .....  BTW what if you find the dodgy one.... are you going to hand over £20 for a new one  :-?

Did you get the MB P/N off the old plugs?

If you do have the MB P/N, I can try and find out who makes them (prob Bosch or Lucas etc) and see if I can obtain the equivalent OEM manufacturer's P/N for you.

If i was keeping the merc, yes i would change em all.....but im selling it and just want to get the warning light to go out.....as im sure a potential buyer will spot the warning light.

Im going to have a go at seeing if i can find the faulty one/ones this morning and then try eurocarparts for them....if i carnt identify the faulty one then yes i will change them all.  :y

Success!

Engine cover off.....located glow plugs....off with electrical plugs and metered each plug to engine ground....one was 0.4 ohm the others were open circuit....so pretty good proof i had 3 knackered glow plugs and one working one. No wonder it took its time to start in cold weather!

Got replacements from eurocarparts.....got 4 of em....about a tenner each.

Had to buy extended 10mm socket and blimey they were in tight...i was trying not to force them too much in case they snapped...but slowly they did come out with a lot of squealing going on! I did liberally spray wd40 on them 1st....and may of been better letting it soak in overnight  :-/

Anyway they came out and new ones went in ok....bit fiddley with the fuel pipes getting in the way.

Ignition on glow plug light came on then after a few secs went off (as its suppose to do) gave it a start and glow plug light stayed off (as its suppose to do)  :y

So if any diesel omega owners are reading this.....then yes you can test the glow plugs by metering them.....open circuit they're knackered.....reading of about 0.5 ohm and they're ok  :y

Another garage bill saved  :y
