My car has a very slight misfire on startup and at 1500 revs when warm, the glow plugs have been tested and are ok, so I thought id check the injectors. Looking on Ebay, a leak off kit was about £20, but Id read posts where people just said remove the leak off pipes and see which injector leaked the worst. So Ive come up with a slightly cheaper / better idea to
see if I had a leaky injector....................bottle tops! :D 8-10mm hole drilled into the top of a plastic bottle top, bung them on upside down to catch the diesel and and start the car for 10 seconds and see if they fill :D

A-Team diagnostics! love it :)


No. 5 has a bit of a pool going on.

Pots 2 & 3 appear to be wet around where the injector goes into the head. If that's fuel, they'll need resealing. Could just be splashback where you took the tops off tho. :)

Yeah, a bit of "splash back" and not so tight fitting tops (wobbly drill) but 5 is definitely the offender here, replacement ordered :D

Interesting!

How much does it cost to do the injectors on a D5?

I sometimes feel like I have a slightly miss/hesitation. If you change into third quite early, say 20mph-ish, it sometimes hesitates a bit. Not in a low revs kind of a way, just doesn't feel quite right. Always wondered if it was a problem or just me being fussy.

Try that little test and see if you have a leaky one. Mine had a rattle when on load as well (pinking sort of)
You need a T30 Star Torx and a 3/8 socket set maybe, it took me 5 mins to swap. Buy some new copper washers off ebay. I used the existing clamps and pipes etc etc. You can get a second hand injector off Ebay for about £50-£60 delivered, just make sure its the right type. 1, 2, or 3. Its stamped in a circle on top of the injector.

They CAN be very hard to get out, Im lucky that mine where swapped into a replacement engine about 2 months ago so came out very easily.

If you need anymore info, let me know.
