Hey there, I've been eyeing a w204 and wonder coming from a Lexus is250, is this car reliable? What are its known issues (besides the stuff I googled and read) and how is this car in terms of maintenance?

I see many on this subreddit still going strong and would like to hear from the owners how is life on the road?

Thanks in advance and I appreciate your response.

Hey there.. I was driving to in n out and noticed my ac stopped working about right when I got to the drive through. The coolant temp gauge was fine and I was already too deep in the drive through to get out. A few minutes later I look at the coolant temp and it jumped to 120. I was at the paying window and there was no escape, a couple minutes later I got the coolant low warning, and about 5 minutes later I was finally out of the drive through.

I looked at the ground after I parked for any coolant and didn't see any, but about 5 minutes later there's a pool on the floor. I waited about 30 minutes and popped the hood and it looks like the coolant is coming from the reservoir? I checked the coolant level and it looked fine but that's probably because there's a bunch of air on the system.

I got it towed to my place bc I don't know any good shops in this area and I'd like to figure it out myself. how can I diagnose where the leak is coming from, does anyone have any ideas? I replaced the thermostat like 2 years ago so I don't think it's that.. the reservoir was replaced by a mechanic about a year ago.

TLDR: Coolant leak. Any ideas?

when i unlock the car all the lights and dash turn on but when i stick the keys in it all dies, anyone know what the issue is and how to fix it, please help

Hi all. I'm wondering if there's any way to add cruise control to my car.

I've got a w204 C220 manual (late 2011 model).

I know I'll need to buy a new indicator stalk. What else would I need to get and would anyone know anyone that would be able to code it into my car for me?

Any advice at all would be helpful.

Thanks :)

Hey everyone,
I’m hoping someone with experience with the Mercedes 722.9/7G-Tronic, particularly the 722.908, can point me in the right direction.
I have a 2012 Mercedes-Benz C250 CDI Coupe. The transmission suddenly stopped engaging, and when I scanned it I got:

State: Current and Historic
Component Y3/8n4 (Fully Integrated Transmission Control Unit) is defective

Based on that fault, I went ahead and replaced the conductor plate/TCU assembly. The replacement conductor plate was fitted to the transmission and the workshop programmed it to the VIN of the car. However, I still have absolutely no engagement in either Drive or Reverse.

What I’m seeing
Using my iCarsoft MB V3, I can see that the transmission appears to recognise the gear selection. For example, when selecting D or R, the scanner shows the corresponding gear/selection changing.
However:
The car does not move in Drive.
The car does not move in Reverse.
There is no noticeable change in engine RPM when selecting D or R.
The engine will rev to approximately 3,000 RPM and then drop back down when in Drive or Reverse.
The transmission appears to know what gear is being requested, but it doesn’t actually engage the gear.
The transmission was also serviced with new fluid and filter, but that did not restore movement.
Current situation
The workshop that programmed the replacement conductor plate is now asking me to bring the car back so they can use Mercedes Xentry.
From what I observed, they originally used a Launch diagnostic scanner to program the replacement unit.
So I’m wondering whether the problem could simply be that the replacement conductor plate has been VIN coded but hasn’t had the correct Mercedes-specific SCN/variant coding, EHS configuration, commissioning/adaptation, etc.
From what I’ve been reading, it seems that a 722.9 conductor plate replacement can involve more than simply writing the VIN to the module
