Was quoted £234.74 parts & labour to replace the motor. The part with a 10% discount is £159.13, therefore, the labour is £75.60. This work would not be covered under the insured warranty.

Decided to have another look myself. With the silencer removed, the flap could be seen to move from fully open to fully closed & back when the ignition was switched on. Perhaps exercising the flap/motor has done the trick. Applied some PlusGas to clean/lubricate the flap internal pivot points, plus a squirt of ACF-50 externally on the cables etc.
What sort of insured warranty have you got?Just asking as my 2016 RT has had 2 sets of headers done due to exhaust flap sticking,The first time i think was done through the 2 year dealer warranty but the second one was done early on this year  due one dealer not noticing it on the  diagnostics after a battery change(they needed to check the rectifier)so i took it to my main dealer and they noticed the flap was sticking and  exchanged the headers and obviously servo etc all under the BMW extended warranty

David. wrote: I've got a BMW Motorrad Insured Warranty. The exhaust system is not covered under the warranty. I spoke to BMW Warranty Services, suggesting that, under the "Electrical system", failure of all electrical control units is covered. My thoughts were that the failed exhaust flap servomotor was an "electrical control unit". Unfortunately, it is not considered to be the case, therefore, the claim is not valid. The person I spoke to at BMW said, if he could swing it any way, he would, be on this occasion, it's a none starter.

Perhaps in your case, the first replacement was under the 2 year manufacturers warranty. If the second one failed within a year, (less than 3 in total), it may well have been replaced because the first replacement should have a least a years warranty.

If this is the case, why would it be necessary to fit a Servo Buddy, https://www.speedycom.co.uk/shop/produc ... ctid=19880 or similar product.

Have not done this myself so cannot say what code you get or if this helps.

The sound heard when switching the ignition on is definitely the servo motor, not the valve.
