Which dealership? Norwood mass why Norwood is Herb Chambers and it is actually in Sharon now. The service manager, Mark, is a good guy. Roni is my service advisor. I suggest you go for a ride or listen to another 2008 car and see if it makes the sound too. Also sit in a 2009 model and see if the sound is prevelent there as well. My only concern is you say you hear the tapping coming from the engine area and narrowed it down to the fuel pump. The fuel pump is actually in the tank which is under the back seat. If the tapping is coming from the engine area it may be the fuel injectors which several other members have noted/complained about. If it is the fuel injectors, the tapping will increase in frequency when the rpms are increased. steviej

I have a 2007 GS350 with a loud tapping sound at some start-ups and a softer constant engine tapping sound. I was told that the start-up tapping is the fuel injectors and the softer engine tapping is normal engine sound, and not to worry as both are normal sounds for that engine. Cubfan

Hi Im not sure this is the same problem as I took the old mechanics stethascope wich is a long srewdriver and put it to were the tapping was loudest and inside some pump in the back of the enginge area they found that it was lound and 2 other cars of the same year didnt have the same tapping banging sound so they replace it and still the problem that wasnt their before is still their.

Your's makes noise and two others do not. That lends credibility to something being wrong. They will figure it out or just replace it I am sure. steviej
gs350me Posted February 2, 2009 Posted February 2, 2009 i think my 08 gs350 does this too. it is at the passenger side rear of the engine cover i hear it. just a light tap tap tap constantly when idling, can't really hear on the road b/c of the road sounds.. but annoying at idle anyways.

Thanks ,well I have an appointment with them Thurday morning to drop it off and one of the head on the road field guy will check it out I hope they dont try to shrug it off because i no theirs a def problem .. I went to the dealership, said it was normal. I requested we listen to a new one. Cold the new one didn't make that much noise, however after the serviceman floored it up and down a speeding strip dealers here use for test drives, the new one made a similar noise. They did say they could replace the brakes through a TSP TBD OR something starting with a T. Hopefully that takes care of the noise, they are also going too work on the dash rattle.
