RW1 0 Posted March 18, 2012 00533 - First check the ISV - sticking or stuck, including the wiring to it, 2nd look for an air leak between the MAF and Throttle Body, particularly in the duct folds. 00527 - Check the connector on the front left of the inlet manifold side wall directly under the brake servo vacuum pipe connection is connected & wiring OK. Otherwise its the sensor plugged into the inlet manifold sidewall. At room temperature it should measure 2,500 - 3,000 ohms. In boiling water, it will go to 175 - 225 ohm if working correctly. That's if they are not old faults. You cleared them down and they returned? . Quote Share this post Link to post Share on other sites
skid 1 Posted March 18, 2012 Yeah all faults were cleared and returned with next check. How would you check for leaks other than listening, does the old "spray carb cleaner" trick still get used? Quote Share this post Link to post Share on other sites
RW1 0 Posted March 18, 2012 (edited) Listen and carb spray is one way to do it. I have some VW stuff but I don't know whats in it. G 001 800 A1 - Engine Leak Detection Spray for Air Intake Systems 200ml. Picked it up at a show for 50p. Normally £15 - £20 iirc. Intake System, Checking For Leaks (False Air) Special tools, testers and auxiliary items required • Engine leak detection spray G 001 800 A1 Test conditions • The parking brake must be applied. • On vehicles with automatic transmission, selector lever must be in position "P" or "N". • Coolant temperature must be at least 80 degrees C . Test sequence NOTE: • The negative pressure in the intake system sucks in the leak detection spray with the false air. Leak detection spray decreases ignition quality of the fuel mixture. This leads to a decrease in engine speed and a change in oxygen sensor values. • The safety precautions listed on the can must be observed. • Connect Vehicle Diagnostic and Service Information System VAS **** (Use VCDS[VAGCOM]). Connecting • Start engine and run at idle speed. • Start VCDS (VAGCOM). • Select Engine - 01 "Engine ECU", Measuring blocks group 001. Observe field 1 & 3 for RPM & Lambda values during test spraying. Edited March 18, 2012 by RW1 Quote Share this post Link to post Share on other sites
