fitted new throttle body as the old one was stalling and revving high some times i have reset adaption with solus pro but the idle still hangs at 1200 to 1400 ive noticed the idle does come down when temp goes higher could it be a cts problem ?

Hi Paul. Reckon you need to scan CTS from cold to be sure. If the idle speed returns to normal when engine hot then that may answer your question. Don't have a solus pro myself and don't know the rammifications of the adaption procedure but I would give the car a wizz round for 20 mins or so and see if ECU needs to learn the new values.

Hi Paul. I assume there are no fault codes and emissions etc are ok. If so, I would be taking a close look at TPS first then CTS. I assume stalling has been solved. Need a bit of scoping to eliminate......

Paul, I have often found it neccessary to clear adaptations (learnt values) before re setting adaptations,would think Solus can do it, regards, Gwyn

CHECK FOR AIR LEAKS,SERVO PIPEWORK ON THESE AND RUBBER CONNECTING PIPES ARE COMMON FOR LEAKS,HAVE YOU TREID SPRAYING AROUND WITH BRAKE CLEANER, OR CAN YOU SMOKE TEST IT FOR LEAKS. I HAVE OLD SCANNER AND SOLUS, BUT FIND THEY ARE NOT VERY GOOD AT READAPTION,I USE BOSCH KTS ON THESE PROBLEMS, MY GARAGE IS IN OTLEY, HAPPY TO TRY THIS FOR YOU.

thanks george ive tried carb cleaner etc no apparrant leaks if you switch lights and hrw on revs drop to 800-900 switch lights and hrw off and idle stays at 800 as soon as you touch throttle back up to 12-1400 i think it could be the solus-pro not adapting correctly i wonder if any one else has tried there solus to readapt yet as its a fairly new machine i did go through to the expert mode with the guy from scanline and into channel 098 and channel 060 but the solus was not supported by that section the customer has car back now and im going to see what happens thanks paul

I have had a couple of these with adaptions that did not reset. As someone else posted you should try and clear the adaptions first. I am amazed that solus wont do it. There is a procedure for resetting. I know I have posted it here before. Do a search, failing that I can post it again.

well i hope so too i dont know how long it has to be driven to relearn and lost a bit of confidance with the solus on readaption

approx 25 miles I think! Paul, I am sure your Solus will erase adaptations, that is, reset the ECU so you can then adapt the throttle body to the ECU. Perhaps its hidden away there somewhere? Maybe a good idea for you to post the query on the Snap On forum, I'm sure someone there will have the answer, Regards, Gwyn

Today I have the same problem! I found this post doing a search. Fix is to reset ECU learned values. To do this, go to ADAPTATION-10, channel 00, scanner asks do you want to reset? Reply yes and scanner shows DONE. Then go to BASIC SETTINGS-4 and adapt throttle body in channel 098. Thats all! Hope this helps!
(Engine code is AKL)

Paul,
Can only re-iterate what others have said as i had exactly the same when i cleaned the throttle body on one of these.Re-adapting throttle body did not work.You must erase learnt values (diff operation).Launch did this.

Have a vehicle with just this problem. I will try the various suggestions already made but I just wanted to ask about a curious symptom wondering if it might be relevant.

Using VAG-COM I can connect but when I switch to measuring blocks, If I attempt to open more than one row, then only one row will show at a time, other rows will display "Error" messages, rows will cycle round at about 1Hz.

Also I cannot get a generic OBD2 connection! neither from VAG-COM nor using other scan tools.

Probably too old for generic EOBD ???

Reset adaptions, reset throttle body and....!

Starts and idles normally.

Blip the throttle and it comes back to 1000RPM (but with no hunting)

Do "Something" to slow the engine below 800 (Slip clutch, turn PAS to full lock, anything really) and idle returns to a steady 800!

There is no urgency on this but it would be interesting to sort it out!

?

Hi paul,
This is a reset procedure for a different fault on golf's so may be worth a punt.

Disconnect battery pos for 1 minute
Reset adaptions - (Using VCDS) 01, Read channel 0 (should show 000)
then save
accept save 000 to channel 0 then exit
Ignition off for 1 minute
igntion ON run basic settings for throttle body
wait until ok - leave for 1 minute
Ignition off - wait for 1 minute
Start engine - NO throttle and run for 5 minutes
Turn headlamps on and heater blower - run for further 5 minutes
Clear any fault codes
Road test.

You can trim a sheeps wool many times, but you can only fleece it once !
