I am missing several of the splash guards under my 2007 SL550 (R230). I have the front engine splash guard (230-690-20-30). However, there are adjacent splash guards that overlap with the front engine splash guard and bolt to the front of the fender liner. I can't for the life of me find the part codes. I am missing the passenger side (left side drive car, if that make a difference). Can anyone help me out?

I am planning to purchase the center (230-524-07-30) and rear (230-524-12-30) but it looks like there are clips and bolts but I can't find out how many are needed. I don't want to take it to the dealer to be installed because it should be simple enough and they will charge me 100's of dollars.

FYI - I am newly registered but this forum has been a lifesaver on several occasions! I hope to be able to contribute something useful in repayment.

 

 

Thanks pmurcury. I still can not locate what (I think) is missing shield on passenger side adjacent to the front engine shield. I’ll attach a picture showing the vacant space just ahead and toward the center of the front passenger tire. It looks like part of a shield was torn off.

 

I think you need part '160' fender liner (with corrugations) from the first list of parts. Part 190 was removed in this photo?

Before you do that...buy some front tires! Those are at the cords!

 

Actually, getting under the car was the only reason I noticed the tire wear (replaced the next day). Checking the front tires from the side of the car, the tread was all good. The wear was entirely on the very inside if the tires. The only way I can imagine the camber being that far off is if it was improperly set with the suspension raised. The car is with the Mercedes dealer for a front end alignment ($180 if they can get in spec as-is, $270 if they need to add camber bolts to get in spec).

 

I recommend the camber bolts, even though they only provide about 0.25 degree adjustment. They are about $20 if you buy your own.
Have the dealer set as close to zero camber to reduce inside wear.

You may also have suspension rubber bushings worn out on the inboard mount of the rear links. This is a common failure for the SL and others. I have pressed in new bushings on many Mercedes over 75K miles.
