Tried to alligh the throttle body on a 98 Polo 1.4 8v for a freind whos tick over is high after he removed and cleaned his TB. Followed the procedure on the ross tech site and got this



then when you switch to basic settings i get this




can anyone tell why?

Is it possable to even do this on this model?

Hi, I cleaned the throttle body on my girlfriends 98 polo 1.0 a few years back and had the same prob with the hi tickover, turned out to be the coolant temp sensor at fault, why the hi tickover prob started when I cleaned the body I never found out, when I replaced the sensor the problem was instantly 95 % sorted then over a couple of days everything returned to normal.

Thanks Mark, will try it.

The clue is in your measuring blocks 098 screen, zone 4 says “part throttle”. In Measuring Blocks 001, there is an eight digit value displayed. With the ignition on and the engine not running, what is the value displayed there?
