TD4 injectors

Hi again... picking up plenty of tips from here thanks for all your help.


Just a question on the TD4 injectors - i've read they are prone to seizing in the head at 100K plus, which is obviously a problem if one fails. Just wondering if it's worth removing and cleaning at next service (this weekend) - would a little copper grease harm anything?

Dunno about the 100k, but in my expeience they can fail/seize time un time again...yer know when sumfing is going wrong when the ride get lumpy...dunt use bosch parts eiver...

Other guys may no more on cleanin un copper grease...persnly, I wud replace not clean after 100k.

eck they're about 150 quid a piece

Aye, bit cheaper maybe...but after 100k, yer have ta owe it sumfing. Check em out first, see what there like un check injector pipes fer leaks too. Bit er Redex can do nay harm eiver..every 4-5 fill ups.

yeah performance is fine currently, just wondered if they we're worth removing when I service in case they're starting to stick. Thought cleaning them might prevent a sieze if I need to replace. Read someone on here had a mare trying to get a failed injector out.

Sods law they'll start acting up after i've had em out!

Ming as spoken, e knows wat he is talkin abawt...wud still fink abawt replacing after 100k tho if they look iffy or are leakin...if even one leaks ya will notice slow drop in performance, even harder to notice power drop in deezel!

guess they're coming out as part of the service - hope they're not stuck!! 60K on the clock....
