TD cold start probs
« on: 25 January 2010, 10:06:33 »
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.

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

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

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.
