Just had a quick look at my throttle body and can't any cables just one sensor. I've got an AUQ. Does that mean I'll have to use vag-com to reset it once it's all back together? Also when I take it off should I leave ignition on or off? Sounds silly but I need to be 100% before doing it. Cheers

Just done my 1.4S mk4 golf and the throttle body was black as your hat cleaned her out and now she is running perfectly. i disconnected the battery and then on restart i left the ignition on for about 3 mins on position 2 and then ran it up on idle for a good ten mins and she is lovely real big difference thank you everyone

i done this today got carb cleaner from ebay (s.t.p one) all car shops near me didnt have any including halfrauds and some never stocked it, suppose not many cars with carbs anymore all fuel injected, well i followed the guide and got throttle body off i have no cable so had to be carefull with the butterfly motor and took it down the shed as a bit warmer, but disapointed in a way as mine was very clean indeed heres some pics.

before cleaning



and after being cleaned not a lot of difference to be honest



then i bolted it all back together and was praying it would start and run ok, fired her up and cold start valve kicked in as revs were up slightly then cold start valve shut off and car was running normal with no problems, wish mine was more dirty to be honest but a good little job to do.

i was kind of hoping it was going to be black but not the case, this was one of those things i keep looking at doing but chickened out as i have cableless throttle was really chuffed how it all went to be honest, well one job off the list now.

Again cleaning your throttle body won't make much difference at all, mainly on a turbo car because the intercooler catches nearly all the oil. It will be worth much more your while to flush the intercooler as a clean and shiny throttle body may look good but will much more benefical to flush out an intercooler that has built up and slightly blocked over the years with oil.

that will be a job for the summer then that one, least i know how to take throttle body off now as im going to paint it i think and wasted a bit of time i suppose.

Anywhere I can find a How To... On flushing the intercooler?

Thanks
