The dealer determined that the left side underbody convertor was bad and they replaced it under their 8 year warranty. There are two catalytic conevertors on each side. After the fix, I took the car for a long drive; the rattle and the HUM in acceleration from 45-50mph are both gone. My next issue with the dealer will be the tick tick sound from a cold start that sounds like a lifter noise.

Hi, My 99 E320 kind of jerks forward or seems to not have enough gas at lower gear when I start driving in the morning and gear shift seems not correct. I do warm the car up for about 3-4mins before driving. After I drive for sometime when I slow down or stop at traffic light, I dont see this problem. What could be causing this? Bad Oxygen senor? Or is it the transmission going bad and not shifting correctly? I am not too worried about the other problems but worried about transi goign bad. What are the typical symptoms of transmission going bad? Thanks much in advance. |

With overhead camshaft engine designs, upon cold start, there's a brief delay circulating c-o-l-d motor oil back up to re-pressurize the top end mechanicals. Tick-tick-tick... As long as the noise clears within a minute or so, it's not considered problematic. (Or you could always drive a Hyundai Accent with mechanical lifters that require periodic adjustment maintenance...  )

I just now they did something to the engine. I would have heard the noise when I start the car in the garage if they did nothing.. I still think this MB's V-8 does not come close to my 96 Camry's V-6's smoothness. Some of you may think I am crazy for saying this, but it is true. Joe

Replying to: hawkeyes2 (Nov 20, 2006 4:04 pm) I haven't logged in for a few weeks and I've missed a lot of good stuff that I can relate to. First, there are some generic things to worry about on a used MB. Both of mine needed front end rubber bushings on tie rod ends and sway bars in the 70-80 K miles range. Since both of my cars had Starmark, that repair was free. It can run as high as $1100 for replacement of ALL bushings in the front end. Symptom is a thunk in the front end as you go over small pavement cracks, etc. Others have mentioned brakes and rotors. I think I've found a solution to the fast wear and the excessive dust on the wheels. A year ago I bought PB brand pads and rotors for the front end and they work as well as the MB brake parts and with almost NO dust. I've only had to wash my wheels every 3-4 months instead of every 2-3 weeks..! And the parts cost about half what the MB parts cost. I bought them from Smitty's Parts Service on the web. I just put the same stuff on the rear and expect the same results. I don't know yet if they will last much longer than the OEM parts, but for the lack of dust and for the lower cost, I am happy so far.. I had all the brake parts installed by a local mechanic for a lot less than the MB dealer's labor charge too..! And since you're looking at a 99, you shouldn't have to worry too much about head gaskets. My 96 needed a head gasket at 115K miles which was 30K miles earlier than normal for the straight six. (It is a design defect on that engine!) As far as I know, the V6 is very reliable; I've heard nothing bad about it so far.. My '01 does have a few more gremlins of the electrical type than the 96 did, but it does have more stuff to go wrong. Nothing serious so far but every once in a while when I open the drivers door, the alarm goes off even though the door was NOT locked!! And gee, even if it were locked how would I be able to open it? This has happened 6 or 7 times in the last year and the dealer replaced a door switch, but it has done it 2 more times since then. Good luck on your hunt for a clean one..! Fred |

Replying to: jodar96 (Dec 05, 2006 6:51 pm) I had searched the internet for cheaper converters and asked my mechanic about them. His advice is to stay away from them because the 3rd party ones don't have the full load of precious metals needed to last for a reasonable time. He did a cheap one for a customer last year and in 3 months it had gone bad and then the customer had to pay for the OEM part anyway. I had forgotten that the left side converter was replaced by the dealer under warranty at around 65K miles. My 96 had never needed a converter when I finally sold it at 140K miles. Converters are just one more item that MB has chosen to cheapen up...!
