hello all,

I have the problem with rmp my 3.2 on idle.
After driving, fast or slow when i stop, rpm ~1000-1100, stay may be 30secs and down to idle rpm. Ago i see this rarely, now every stop on traffic light.

i am change:
1. Spark plug
2. MAF
3.Throttle
4.Ignition coil change with service action
5. Oxygen sensors
6. Timing chain and tensioners
7. Check many sensors.

Where my problem?

thank you.
 
Yes, i have last version software update 8036
 
It sounds like what people say to look out for when the timing chains are faulty. I'd look at that and the tensioners etc.
 
If you read my first message, you can see- i am change timing chains and all parts -tensioners and etc.
 
May be 6 months ago. For BMJ engine with DSG this is last version.
After update more stable rpm when press accelerator in stay position : for example 2000rpm , before update rpm up an down 1800-2200

You need vcds to do throttle body adaptation. Not sure if /how well works on non turbo engines.
 
Doin the chain etc is very expensive the adjusters are £600 for just the parts.
