Tech question. My dealer is telling me that one of the intake tuning flaps is sticking. They claim it is throwing an error but nothing shows up on the dash. They car drives perfectly with no indication on the TFT. They also say this part can't be ordered separate so I'll need to replace the entire planum for $10K. Has any ever had this issue on their 458? This is holding up delivery of my Speciale so any info would be great. Thanks.
Yes, they do stick. If under warranty, it would be covered. There is no driver(light) indicator that would be on, the motronic would log the code. If it is a 1521 or 1523 have them check for a vacuum cap missing at the vacuum tank or the air gap at the two sensors for the flaps.Unfortunatly the flaps would need to be removed anyway. They could also active test the flaps with tester. mark a line on the top of the valves to see if mechanically sticking.
