Squeaky Park Assist

I was actually wondering if there was something that I could tweak to change the pitch of the unit to stop the squeak. Has anyone ever tried this? According to Volvo it is a standard parking assist system and it was fitted as an extra. So there must be a way to tune this noise to be less 'squeaky'. Isn't there?

Well I've just fitted front and rear electromagnetic parking sensors. And there is no adjustment regards the sound the speakers make, and I doubt there will on yours either. It might be worth giving it a good blow out [the speaker that is] if you can get your lips near to it, could be a bit of fluff stuck in there.

Just to let you all know...... As my S40 T5 was still under it's 1 year used car warranty with the garage I bought it off, I took it back to get the parking sensors fixed. They deteriorated and eventually only worked every so often, so i took them down to my local Volvo and they fixed it all for me under warranty. They now sound great and work well as I think they upgraded the parts. The service at Hildenborough Volvo was not that great however. As I had to phone them at the end of the day to find out if my car had been fixed, and their reply was 'yes, it was fixed around about 4 hours ago'. Great, thanks for the notice!! They also decided to give my car a 'complimentary check', and apparently I was 'desperately low on oil', so they took the liberty to fill it up for me!! I checked the oil around 2 weeks before and it was fine, and on recent inspection after their 'top up', the oil level was well over the recommended amount. Thanks alot, so not only did they ram a load of oil in that I didn't really need, they charged me about 18 quid for the 1 litre they put in!! Not that impressed to say the least!!
