Hi...
New here from another site. Ive got a non starting TD in this recent cold weather. The battery and alternator are both good and I've been told the glow plugs are also good. I have dismantled and cleaned the in tank pump and it is good too . As I turn the engine it nearly fires but wont and as i turn her over I get the usual blanket of smoke as it turns. It has on occasion started but rarely and when it does a huge pall of smoke comes out. Is there such a thing on this BMW engined car as a fuel heater? If so should I be looking to replace it? I dont know what else I should do as this now has me foxed. Although an old girl (1998) I am loathe to get rid of her. I wouldnt get much for her anyway and she's only done 90000 (genuine)
Please Please Please help me if at all possible.
Thanks...Mike

Glow plugs and fuel heater (part of filter housing) would be first ports of call. Glow plugs most likely. Dead easy to check on 2.5TD as well.
Welcome to OOF :D

Where abouts are you OldT?

Hi again
I'm in Scotland...Ayrshire.
How do I check/test the glow plugs? ''Easy'' you say? I hope so.
Cheers...Mike

In relay box is a connector along top edge. Unplug. You will see that six of the wires are in a set of connectors near easy other. Measure from each of these to 0v, each should be approx 1ohm

Its the glow plugs. Just fixed the same problem with 2 new ones.

That sounds helpful, where exactly is that TB :y

Change all 6 together. If 2 are gone, the other 4 are ready to let you down.

& don't be tempted by the cheap ones on e-Bay, buy the OEM Beru or Bosch

I've fitted NGK's to mine with no problems :y
-
have you done the paper clip test :question
you should replace all glowplugs.
whens the last time fuel filter was replaced

Same here - still performing well after three years.

Yep - and especially due to the work involved!
You don't want to remove all the inlet manifold etc too often.

Yep, used NGK's on both my Tractors. Almost daily use with my first one for 5 years and current one is now in third year.

Hi again and thanks for all the info!
Just one thing...is there a specific procedure for removal of the glowplugs? I have heard for example that No6 closest to the bulkhead is a bit of a pig...Does much have to be removed?
Thanks again...Mike.
PS..no I havent done the paperclip test yet.
-
Just another thought...
When it does start it runs like a dream, so if a glowplug or two had gone, would it not also affect the general running of the car?
As I said...just a thought.

No, the GP's are only used for a cold start, it's the fuel heater that's on and off as your running in cold weather :y

Basically, you'll need to remove the inlet manifold and 'turbo diesel' plastic jobby.
I find it best to use a deep HEXAGON-type socket (rather than bi-hexagon type), as it reduces the risk of rounding-off the plug nut.

Thanks for all help...
I'll do the glowplugs then next time I have some .(time)
I have heard also that sometimes a plug or two can ''fuse'' to the head...is that true? If so what on earth can be done then?? Would still like to know if there is a ''how to'' on this subject too if poss.
Thanks again in anticipation etc... Mike.
