Idle Stab Valve- Error Code

[Ice White Socks 0]

Hello,

 

Having a bit of trouble with my VR6 stalling at the moment. It went in for for a door handle this morning and they hooked it up to a diagnostic (for free 8) ) and it came out with error code 0215- Idle control below adaption limit. This doesn't look like a VAG com code :? The notes on the job sheet said 'recommend clean throttle body and replace sensor'. Could this just be a sticky ISV or does the fact that there is an error code mean that its an electrical sensor :?: If so, which one and how much :?:

 

Current repairs this year to date are door handle, headlight switch & Wiper motor- I could run a porsche for the money that goes out on this Corrado :cry:

 

Anway cheers for any help

That is similar to a VAG-COM code mate. It basically means the ECU adapation limit has been reached and therefore has/had no control over it. You need to ensure the throttle position sensor is setup right. Needs to show 14 degrees or less fully closed, and 90 degrees or higher at wide open throttle. To check these you need to go into the "measuring blocks" setting in VAG-COM, or the VW scanner's equivalent.

 

A clean out of the ISV will also help but you can test the ISV by removing it and connecting it directly to the battery, but tap the positive cable on and off repeatedley and see if the valve jams shut or open.

 

I have a good spare if you need one.

Cheers for that Kev- It was working fine though until this morning- Can the throttle position sensor setup drift with time then or is it kaputsky and time for a new one. I'll make an offer on that ISV is thats what it turns out to be - am hoping throttle position sensor though cos its a bit cheaper.

By the way where the hell is the ISV anyway and how difficult is it to remove :?:

Hi there Mike

 

Here is a pic to give you an idea were the ISV Valve is and the T.P.S Switch is :mrgreen:

Its a easy to get off,give us a call if you want a hand :D

Actually that would be a real favour, It would be a real help if you could show me how to clean it out and tell me the best stuff to use. I will give you a bell tomorrow some time and try and grovel half an hour of your time- Thanks for the offer :D

The TPS shouldn't really move out of adjustment but they can and do wear out with old age! They're about £40 from the dealer and the ECU will need resetting after fitment so that it resets the throttle angles to the new TPS. Worst case scenario will be a knackered throttle body as excess movement there will cause the TPS problems. I doubt your ISV is kaput as they're last for ages on the VR.

When it comes to the T.P.S switch and resetting the E.C.U is it just a matter of disconecting the battery for a while or is it a Vag Com? :(

My car on very light throttle is surging back and forth so i was going to stick on a T.P.S Switch on to see what happens but if the E.C.U needs resetting might try that first to see what happens :?

Chirs, is it surging (aka hunting) at or around 2000 rpm with a very small throttle opening, i.e. cruising behind in line of traffic? If yes, then a new TPS might help but it didn't cure that problem on mine :? At some stage I'm going to pull the throttle off and inspect if for wear because if the butterly bearings are shot, not only will there be an air leak, it will also throw out the TPS alignment :x

 

Yep resetting the ECU is just a matter of disconnecting the battery for 15 mins +

 

Try that first. After you reconnect the battery, start the car, let it idle for five minutes or until the rad fan kicks in and then take if for a drive making sure you give it full throttle at least 4 or 5 times, for say 10 seconds each time....in 3rd and 4th
