Hi everyone!
I am the proud owner of a C220 SportCoupe from 2003 with 155 000 km, automatic tiptronic gearbox and I have it for 10 months. Recently started to make me some troubles, two exactly. I searched the forums but i didn`t found anyone with the same problems.

1. After going a few km`s and the engine reaches 80 degrees it does not accelerate and if i swtch it to manual does not overcome 3,000 laps . Usually if I drive a few km`s more it`s starting to function normal. I tested it with acceleration from 0 to 100 km and i got 10.3 sec like the manual says.

2. If i stop the car when the engine has around 80 degrees or more it does not start and it spins like it has no gas in the tank. The engine starts again after 30-40 minutes when the temperature is around 60 degrees or less and then it s working fine until it reaches 80 degrees again. I mention that the car never stopped by her self.

I went to the tester, a Launch X431 and I found 4 errors:

1. P1664 (-008) Electric heater open - Current and stored
2. P1354 (-002) Syncronization between cranckshaft and camshaft. Frequency or camshaft sygnal is too high. - Stored
3. P1354 (-002) Syncronization between cranckshaft and camshaft. No crankshaft signal - Stored
4. P1354 (-002) Syncronization between cranckshaft and camshaft. No camshaft signal - Stored

I removed the camshat senzor and it seems to be ok, it is very clean (doesn`t have any iron particles on it). I even changed the temperature sensor with a new one.
I checked the crankshaft sensor too and it seems to work. It measures the r.p.m. `s when the car doesn`t want to start.

I don`t understand why the engine is going very good until it reaches 80 degrees and after this it`s like someone is coming and it`s throwing punches to the engine and he is starting going dizzy.

Please help and telp me what parts i need to change!
Thank you very much!

 

Hello again!
I fixed my car!
It was the cam sensor that needed to be replaced and the egr valve that was making black smoke!
Thanks a lot for suggestions, but now i have only one error left P1664 - Heater booster circuit open and i don't now how to fix it.
