2002 / W220 / Dead Battery / 3 Dead Coil Packs

cgilmour8698 — Mon, 18 May 2026 14:17:02 GMT

I NEED YOUR HELP! Awfully Strange, leads me to query the MB World Audience -

Following the installation of a brand new battery / OBD Scanned to find 3 dead coil packs on the same bank cylinders 6, 7, & 8 all dead or misfiring / while examining this in the night I noticed Catalytic Converter glowing red hot - so I unplugged the injectors to these dead coil packs - Now I am parking the car until I can perform the necessary repairs - Problem is that I am not in a city that I a from nor am I able to afford to live in a hotel indefinitely while I examine and fix these issues concurrently. While I am ordering the plugs and packs - I have to wonder what more I should be doing to examine the ground wire and or wiring that may have lead to all 3 packs on the same bank failing simultaneously.

The car was only driven a few miles before I parked it to find the dead coil packs lead to raw fuel dumping into catalytic converter which prompted me to unplug the electric lines to the injectors 6, 7, & 8. Now I am in a situation. And Time is not Friendly for me to be parked for such a length of time. First I need to diagnose my catalytic converter without any special tools to do so. Then I need to diagnose the reason why these 3 coil packs next to each other all died simultaneously.

Following this I need to order parts and get them in. I am not a mechanic - However, I am not well enough off to pay a mechanic - Hence I have no other option than to fix whatever it is or throw the car away.

I NEED YOUR HELP! Prioritize - Diagnose / Order Parts / Repair / Replace Etc...

Hello i have a w220 320cdi 2003 my gear selector was an issue so i changed it. The trim was not still put on i wanted to try if it works and it worked fine i drove it to test it and it works perfect. When i put everything back i tried to start it and it doesn't even crank. The gears work on display, break switch works fine what could possibly be the reason to not start and doesn't even crank? While i was working the battery minus was off.

Throttle will not relearn . See pic

Is the 17 voltage on throttle 2 how the ME puts the car in limp mode ? It fails every time I try to do a throttle reset or reset all adaptions .
The car does have a C1041 ESP fault code . I believing this code is causing the no throttle response .

esp code

Sorry about the blur but notice 17 volts on throttle signal 2 and throttle not learned ? Thanks my foot pedal is good all wiring is good and voltage from throttle pedal to me is good on signal 1 and 2 .

Burning Oil Smell but no leaks

Still have my 2004 W220 S500 with about 185K miles. Over the past few months I have noticed a burning oil smell after driving a while but I have no visible leaks or smoke. Just in case I had the Valve Cover Gaskets replaced and that had know effect.

Any thoughts...Thanks in advance

ABC line failure

Well after 22 years I finally had the dreaded ABC main line failure under the engine. $3300 later she is perfect. Why in the world Mercedes would put this line in an in accessible spot is beyond me, but alas I was VERY lucky for many years.
