Tick over high revs

[Rhosj]

Ok on to the next problem

start engine let it run for a minute or so then the revs go from approx 800rpm to just over 1000rpm

turn engine off restart goes back to 800rpm then rises again

Mine doing the same do u hear a click when it goes up I've traced mine to intercooler pipe clips leaking

Mine doing the same do u hear a click when it goes up I've traced mine to intercooler pipe clips leaking

not too sure on the click i will check

as for the intercooler leak did that fix it?

 

[dancupra225]

Well move the pipe and the revs still go up but ordering new clips from Audi this week about 40/50 quid bud or air leak somewhere

 

[Rhosj]

Nice one ill take a look tomorrow and see if i can find a leak

 

[SmithyAG]

What clips are you ordering for 50quid??

The only clips on the hoses to/from intercooler are about 4quid each?

 

[dancupra225]

Not sure bud haven tighten clips put on but g ping Audi 2morrow as think talking crap as normal

 

[Rhosj]

i had a look today but nothing seem to be leaking
moved the pipes when its at normal revs and nothing happens then when the revs increase i moved the pipes and looking for leaks but its still doing the same

 

[SmithyAG]

2.0 tdi with or without DPF?

If with DPF is it trying to do a regen?

 

[Bramley]

mine does exactly the same, so annoying, most of the time it stops my aircon working aswell!

 

[dancupra225]

I had my boost hoses new clips and strong cable ties to hold for now seems to be better now

 

[Rhosj]

I dont think it has DPF

Mine does this when I've been abusing the battery, either engine running but stationary with all the electronics on or if it's been sat for a while with radio on etc it'll pick up the tickover speed to approx 1000rpm. After a short drive it'll return to normal tickover

Could be unrelated but that's what I've put it down too!

 

[Rhosj]

Thats mad thinking about it i didnt use the car thurs/fri/sat then sunday morning i drove the car and it didnt happen all day then monsy i used the audi to jump start my van and ever since its happened

 

[Boon]

At tickover it may not be putting out enough ampage to power/charge, so may need the extra rpm to increase the current?!

Any one else have another view on this?

 

[Graham89]

Mine does this sometimes. It'll tickover at 1k. If I drive for a bit it'll sort itself out so I haven't worried about it.

 

[Rhosj]

anyone resolved this problem before?
