I Thought I Finally Fixed My CL65 AMG! INFURIATING Problem With My Twin Turbo V12 Engine!

1. Ok, everyone. What in the world do you think is wrong with the car?

2. A&E AND MBZ technician [ret] here.
   Gap spark plugs with a WIRE gage.

3. Have radiator rodded. After 135k miles, they DO plug up.

4. Sounds like the adventures I've had with my Peterbilt 379. I have Cat C15 tuned to 800 HP and 2850 lb/ft torque. I've had to chase high EGTs, high coolant temps, High oil temps, since it was tuned. I've done bigger radiator, new thermostats, new water pump, new oil pump, on and on. Just recently figured it out. Bad clamp on charge air cooler would loosen after a few hundred miles. We also found a fuel restriction at the water separator filter. The housing was cracked and letting air into the fuel, so we replaced it with fass system.

5. Maybe try bleeding it without the bleeder valves removed.

6. DWA

7. Nummer Zwei (German)

8. I think we need to make a 12 coil package that lives on each side of the engine with wires over and delete the coil pack.

9. No fender covers, hack.

10. Nummer 2

11. @26:29 my wife! Lol

12. So where could we get a twin turbo v12 fix that wouldn’t break the bank? Under 60k that isn’t gonna be an absolute headache.

13. Wish I could get my car to do the turbo boost

14. Every time I run across a CL on MB Market or AutoTempest and start to get tempted, I think of just the time I'VE spent watching you try to sort this one out, and the temptation goes away. Thanks for indirectly preserving my sanity, Alex. I've got quite enough on my plate with one old and one new Mercedes lol

15. Damn you Alex. My goddamn Google started playing that shit Blink noise because of you.

16. I suspect that the feed fuel line from tank to fuel pumps may be internally collapsing restricting the fuel flow. The liner may be delaminated due to heat, impact, age, low pressure caused by too much pump, or????

17. New subscriber Alex.. Gotta tell you dude.. watching this was more entertaining than Lawrence of Arabia..
    God Speed man!! You’ll bring this baby back to life.. keep them coming please..
    I’m a Merc owner too.. haven’t had the courage to even look at the CL65 badge.. what a car..

18. How's the thermostat? Is it opening correctly?

19. Hi Alex … Any news regarding your CL65 progress?

20. Thank you so much for the time & effort you spend in these videos. I have an SL-500 and two Cayennes, so I feel every pain and aggravation that you go through when repair events don’t happen according to plan. However you are pure comedic genius, I can’t help but laugh at your pain & suffering. Sorry, I routinely go through many painful episodes on German car repair & maintenance, but I don’t handle the stress well at all. You on the other hand maintain incredible composer in front of the camera. For us motor geeks you are extremely entertaining, more so than most anything on television. Keep up the good work, keep up the great attitude. Us German car owners will go broke together, but some will maintain their sanity better than others.

21. This Benz is a giant turd. I just scrapped my low mileage E320 that wa. Nothing but trouble

22. I think it's the charge cooler radiator.
    You saw the flow change and attributed it to air coming out, what if it's scaling inside it ? The new pump overcomes the clogging temporarily, but then the deposits move around inside the radiator and it clogs back. Also, you need to have temperature verification. So, with the inlet temperature sensor proven to be good, you have to rig a way to prove the temperature with a different device. How about a thermometer with a measurement rod?
    Put it through the test cap and do a test. Once you get a direct thermal-contact reading from the charge cooler system that confirms the reading of the ECU, then stop the electrical tests and maybe send the charge cooler radiator out, to be ultrasonically cleaned and flow checked.

    Good luck with this, a nice series.

23. could the front heat exchanger be partially clogged?

24. ECU

25. Yes

26. Hay, ya know yer sopost /o empty out the gas tank come on bro

27. The sensor that Mercedes gave you has a wrong part number or the ecu has a faulty section?

28. You asked what car viewers have that are a source of unending trouble…2008 CL550 here. Problems are always weird. Never easy. BTW, please consider adding a little content about those pesky wiring harness connectors that always break. If you have any tips for getting those out without breaking connectors that are heat/age brittle, please let us know.
