2.5TD poor starting
« on: 02 February 2009, 19:12:28 »
New year new battery! were would the best place to start be with my 2.5 TD as I am finding starting in the mornings. it sort of coughs and splutters and I killed the battery trying to start this morning! once started It starts on the button but it's getting it going in the morning, The colder and damper the day the harder to start. I am thinking glow plugs but I have been down this route before with another diesel and changing them made no difference.  :(

Try paperclipping it (about 1/3 of tractors are paperclippable), if you get General Glowplug error, then thats a clue....

Failing that, measure the glowplugs, should be just over 1 ohm. Open circuit, or less that 0.8 ohms is a sign there are fubar. Change all 6 together.

Do you know how long the glowplugs have been in?

between each injector is a rubber or neoprene pipe these allow excess fuel to be returned to the injector pump, if theyare split or leaking then you get bad starting and lumpy running till the air is all gone and replaced by diesel, hence the suggestion to check them as they are a lot cheaper and easier to replace then the glow plugs!!

Do the checks, but I'd reckon on the glow-plugs being naffed.

As 'TheBoy' says - change all six, and don't use cheapo Ebay ones.
Reputable motor factors flogged me a set of NGKs for 36 quid-ish - well worth the cash!

While you're at it, change ALL the leak-off pipes as a matter of course. Buy a length, I got 2 metres for a fiver! (NQA).

Changed my Glow-Plugs towards the end of last summer and it starts 1st time no matter how cold. Used the bike for 10 days in a row and the car still fired up 1st time.

GSF do BERU ones pretty cheaply as well - not sure about the BMW engine, but they're the only ones which last on Citroen/Pug diesels.  I've got the leak off pipe from halfrauds in the past - even includes the little rubber end caps and still does the job.

I have just replaced the glowplugs on mine as I was having starting problems. If the car eventually started then she was lumpy for a bit with clouds of smoke. However, once warm she would start on the button.
Now I have absolutely no problem starting. I bought the ones off of ebay for £20 before I read posts about reliability. However, so far they are fine.
I found fitting these a pig despite what other people said. If you do it yourself make sure you obtain gaskets for the inlet manifold before you start. Do it on a warm day as it is very fiddly. ;)

Beru are OEM on BMWs I'm told
That's what's in mine & no problems for the last year

No special tools. However, handy to have a 1/4 in socket set with extension as well as 1/2 in set. Also a telescopic magnet to pick up the nuts you will drop.  :'(
Don't think there's a write up. One of the members was able to do this job without removing the inlet manifold, God knows how! :o

That's at least twice as fast as normal humans?

You will need nailbar to get manifold off/on.
Get gaskets too, mine were 50/50 cement.
I used hylomar blue, all I had. 1hr 50, I thought I did OK.
& Yes I had a telescopic  magnet thingy.
Perfect now in the crappy weather even with poor battery & ebay plugs 20+p&p.
