eBay Listing for a repair service.


 Paulison Corp. specialize in repairing all types of Bose amplifiers. Our service is used by main dealers and individuals We have been specializing in servicing these units since 2015 done over 1500 units repaired to date. What fails and why with many of these cars there is a problem with water ingress.

 On the Porsche this is due to with the panoramic roof have issues with the roof drain blocking or splitting, also the sunroof assembly splits in the rear corner allowing water to enter the car - straight on top of the amplifier.

 The amplifier usually shows signs of water damage which can be moderate to severe this causes problems with:-

 No sound

Draining battery

No mmi screen

Random components protect Loss of channels Complete failure -


 this is often down to electrical surge which damages the delicate components within the amplifier - occasionally this may result in recoding being necessary. If you are unsure - please send images of board and we can advise before sending. Repair We carry stock of ALL parts required to rebuild these units - the data is never changed by repair so therefore the units are plug and play on return 80% of the time. *** ** 

***A small number of units may suffer from corrupt VIN memory, this will need recoded to fully function **(ONLY LEFT SIDE PLAYS SOUND) We will try to inform you if this is the case (BUT SOMETIMES ONLY HAPPENS AFTER THE UNIT IS INSTALLED ON THE VEHICLE) - it will be your responsibility for recoding costs as this is beyond our control

Counterfeit / Replacement Boards There is now a growing number of counterfeit boards circulating on eBay - please bear in mind that these units are a very poor-quality replica - and WILL need coded on fitting regardless and the ' one model fits all ' listing is completely untrue - there are many model numbers / variants tailored for your vehicle. We are now receiving them for repair on a regular basis ... on failure, most of them are completely scrap. 

Removal The unit is located at the rear of the car on the right-hand side - pretty much all the trim has to be removed to gain access . the amplifier is mounted to a bracket/frame (please remove this - it will make the packaging smaller).

 We now cover all models of Porsche 2017-up Cayenne Macan 911 Panamera amplifier units.
