Idle issues

bane1985 · Feb 5, 2019

hi everyone new to this but here goes
I’m now the proud owner of a 2001 discovery 2 and love it I’ve had it around six months now and waited to get it through its first mot with me before touching it.
Great news it only failed on a gatter.
So work begins I’ve done egr valve delete and injection harness so far. And it’s like a different car already. The only 2 issue mechanicly atm is every now and then the when coming of acceleration the idle revs on its own from 750 to 1000 a few times then stops and sorts its self out I’ve cleaned up map sensor. I’ve read it could be idle control valve? Needs cleaning but don’t know we’re this is or if easy to do. Also there a sucking noise when under load ie up hill from glove box area could the too be connected I’ve looked and the pipe from intercooler to turbo, turbo side looks bit worn maybe air leak. I’ll shut up now lol

Presumably, you have checked the air filter.

The symptom described seems like a clutch switch issue(unless it's an auto cos you didnt mention the transmission type).... as about the bolded part, no such thing on a Td5

Ps it happened in my last car and turned out to be lamber sensor which was a petrol car. I bet I sound like a tool as this is my first diesel and no nothing about them just learning as I go

I bolded the "idle control valve" in the quote and told you that there's no such thing on a Td5... being manual the most suspect is the clutch switch

I think your right mate about clutch switch as it idles funny I dip clutch up and down then it stops. Is this separate part to master or slave cylinder.

Think it's somewhere on the bulkhead from memory, on the fluid lines..?

On a 2001 modell it should be close to the fusebox toward the bulkhead on the fluid pipe
