Hi ppl,

Please can someone help me, i have an a3 1.6 petrol se 54 plate and when I start the engine, the rev meter fluctuates between 0 and 1, this occurs regularly and even switches the engine off unless i put my foot on the gas and rev it up myself, any ideas how to solve this problem?

welcome to the forum. a fault code read would really be required to see whats happening. you really need a vag specialist or other garage with vcds. could be the throttle body needs cleaning or recalibrating.

Thank you Zollaf, i have taken it to the garage however although they noticed the problem, they could not find a fault code for it when attaching the device they had. :s Should i take it to another garage?

do you know what cmputer they used ? if there is no fault code, you look at live data to see whats going on. i suspect the throttle body, but not experienced on this particular engine, but it takes only a few minutes to re adapting.
there maybe a memeber close to you with vcds that could help out, look in the vcds section.

I have no idea what was used, but they gave me a fault code for a delay with brake lights and when i brake, so it may not have picked it up

I reckon intake manifold flap is faulty if it does that at idle, ideally should remove & take apart to check if internals are damaged, MAF is another.
