Ok cannot figure this one out Replaced my lambda ( original OEM ) because of high fuel consumption ( 55 litre on 400km ) also because the car will fall out when it is hot it drops to 400 rpm and then jumps op again now what is really strange is when i disconnect my lambda all is fine it runs like it has to do but i think it runs in save ranges the ECU provide the car to run with But why does it do this when i reconnect my lambda and only when the lambda starts to work ? in cold start all is fine
Did you buy a decent OEM quality part? I've not had any luck with anything other than Bosch on my VW's
When you disconnect the HEGO, the fuel mixture defaults over 10% richer. This suggests either your HEGO is not compatible with the ECU or you have an air leak. Regarding your original problem, I suspect you have other maintenance issues.
Original Bosch 0 258 003 584 Lambda is in it air leak test i did it with brake-cleaner spaying it when the engine runs no fault there Maintenance issues ? All that could be replaced is done with OEM parts All sensors , All filters , All liquids ,Spark-plugs , timing-belts , Chain , Hoses , .....so all you can think off
hmmm with the Lambda disconnected it now starts to do the same less heavy as with lambda . down to 400 rpm hiks 2 times and then settles at 750 rpm
