Help! 2003 E500 diesel knock on V8??
Can you fellow 2003 E 500 owners tell me if a slight diesel type knock is typical for this model? I hear it around 1500 -2000 rpm's. Dealer says that this is how the engine sounds. Engine management- CPU says nothing wrong.
Thanks
Thanks

P-B-07-00/21f - JUL03 2003 E500 Engine Noise
Engine ticking (piston slap like sound) noise complaints when accelerating between 1200 & 300 rpm, replace motor mounts with modified motor mount part # 220 240 05 17 and reset flywheel adaptation.

I just looked up the TSB and here's the language for E500's:
For E500 a modified motor mount, part no.211 240 05 17, is installed as of chassis no. A224352. On vehicles prior to this chassis no., remove part no. 230 240 00 17 and replace with part no. 211 240 05 17.
Reset the flywheel adaptation.
Note : On vehicles E500 (211.070), warranty claims will only be accepted from vehicles with chassis no. A224352 and lower.

Bad engine mounts for sure, i had the same problem...and for the life of me i couldn't figure out. My SA always told me thats how it suppose to sound, but then one day i took one of the tech out for a ride, he instantly pointed out Bad engine mounts, since then life couldn't be better. Make sure you get this done before warranty expires, or else i think it suppose to cost about $1200-$1400. Good Luck.

Just got the car back. The motor mounts did the trick! No more diesel sound.
Also i had a slight squeak at low speed from my brakes and ended up getting both front spring clips replaced. That did the trick.
Lastly managed to squeeze in my last service before 50K came up.
Did this all at Catena under warranty, service there is excellent.
Tommorrow will be putting on 19's AMG style. Maybe i'll post pics.
Thanks all for your input.

Great to see a good result, and another example of the worth of the board.
