High idle
I am new to the forum, would like some enlightenment on the following;
I have a vw polo 2007 1.4 tdi, when I start the engine the car idles really high, up to about 1500 rpm?
Has anyone had the same problem?
Really need help on this
Thanks in advance

Re: High idle
Does it settle to a normal idle after warmed up?
Any other problems while driving?
Could be the coolant temp sensor.

Re: High idle
No it doesn't settle the idle is still high even when the car is started for a while

Re: High idle
Clean the throttle body, check the EGR isnt blocked, change the coolant temp sensor

Re: High idle
Is a throttle body check/clean ever done as part of a dealer service routine?

Re: High idle
Could be a turbo or something to worry about?

Re: High idle
Very unlikely to be the turbo. Do what we’ve recommended and go from there

Re: High idle
Quick update, haven’t changed anything as of yet, idle seems to come down just under 1000 rpm when driving for a bit

Re: High idle
Just under 1000 is still high. Should be around 680-750 depending on engine type.

Re: High idle
Try getting someone to check what the engine coolant temperature is claiming to be - or as suggested, just replace the engine coolant temperature sensor.
