K-light connected to the fuel filter?

Post by StevieboyTD »

Just a curiosity more than anything, my D8 TD sometimes struggles to rev over 3k.

If i keep my foot to the floor it slowly bogs down and won't pick up. When this is happening the engine light comes on.
When i let off the throttle and the revs drop down the light goes out.

I'm wondering if there is a pressure switch to show when you have a blocked filter maybe?

Just that it's happening a lot right now as i've fried my clutch towing a trailer and i need a few revs to go anywhere!

Have a read of this thread, may be of help!
Also this thread; even though it's for an HDi some of it may be relevant.

That first link looks familiar ;)

Looks like the answer is yes, i went out today and got a mile away from home and the car all but died on me, thankfully i was at the back of the traffic so i could just roll backwards to the side of the road. Popped the bonnet, took out the fuel filter and it started fine with no engine light.

Good job i was on my way down to the workshop to play with my fuel system today!, Tank strainer has a small amount of muck on the inside of it, and i've put an inline filter in the engine bay before the engine filter so it's belt & braces & bailing cord :D

AND (best part of the day), while stripping the gearbox off a scrapped Xantia (or was it a Xsara?, the one with the top mount IC), i found a virtually brand new Valeo clutch :D

Just need to sort the droning form one of the wheel bearings and it's back to everything being hunky dory :D

Doh! I'd just remembered reading it, didn't look at the author! :oops:
Glad you've fixed it!
