when cold its fine soon as it gets warm tick over up and down my rs2000 does the same any ideas on what it could be?

First thing to do is get some carb cleaner or petrol and clean out the ISCV (idle speed control valve)

ok then if it still does it then ?

Hi, not sure if it works same on mk5 etc but on mk4 xr3i you had to leave it ticking over for about 10mins so it would relearn itself, maybe yours has the same system?

ive just changed the throttle sensor and made no difference

Did you remove and clean the ISCV?

It's not the same as the throttle sensor.

It was the iscv that caused this on my old gti s plate, a few years back.

A fault reader is only as few quid for that year, if you wanted to make sure before getting the spanners out.

I have a spare 130ps ecu, if it turns out to be that - but I doubt it.

What you need is to clean this:

nice one will do that the weekend see when u change the ecu on these once its been changed does it have to go on a rolling road

HOL

There is a little bit of learning that it does in the first few miles, but I used a 130 ecu on a 105 car with 2.0 cams and throttle bodies.@
