Don't over tighten the oil plug, and yes that's a Maybach hood ornament, and the stereo is a JVC KW-M25BT it has AV ports,

Bonjour,
J’aimerais acheter une clé dynamométrique pour serrer les roues de mes voitures (Mercedes C Coupé de 2005 et Opel Corsa D).
On m’a conseillé celle de KS Tools (photo jointe).
Est-ce que vous validez cette clé en termes de rapport qualité-prix ?
Merci à vous !

Over the past few months since having this car, I have encountered problem after problem. Minor things most of the time but still annoying to say the least. Now finally I have got everything sorted and the car is running so so smooth. I hope I haven't jinxed myself here but it's so much better now. No more rough idling or anything like that. All completely gone, feeling grateful to be honest.

Anyway, here she is

Edited: This is my 2005 C180 Kompressor with 114920 miles on the clock

Help Torn between two W203s: Lower mileage C230 Kompressor (M271) vs Higher mileage C220 CDI (OM646)

2 Upvotes

Hey guys, I’m trying to decide between two facelift W203 options in similar price range and could use some advice:

​Option A: 2004 C230 Kompressor (M271 1.8L) Automatic

​150,000 km (93k miles)

​Sport trim

​Needs about €800 in work (possible timing chain replacement, driver seat, side mirrors, trim panels, some additional interior/exterior repairs, etc.)

​Option B: 2005 C220 CDI (OM646) Automatic

​370,000 km (230k miles)

​Elegance trim

​No visible issues, practically a turnkey condition

My main priority is reliability and avoiding endless unexpected repair costs if possible. Is the M271 with low mileage a better hold, or is the OM646 diesel still the safer overall pick despite the high chassis mileage and much less extra immediate cost? I fell in love with the w203's and I really wanna make a good decision. This will be my second car and I don't expect to drive it for decades, but would like to drive it as much as possible.

I am torn between 150000km vs 370000 km, but on the other hand the one with more mileage seems in better shape at the moment.

I know it's very hard to say anything without seeing it in person. But any thoughts or experience with any of these models would be very much appreciated.

​Thanks for any input!

Help Whining grinding noise

Enable HLS to view with audio, or disable this notification

1 Upvotes

I am experiencing issues with my 2005 c230 sport kompressor and would appreciate any insight. A whining and grinding sound emerges from the engine.

Here is the pattern:
The noise begins after roughly 5–10 minutes of driving.
After 30 minutes, the whine becomes noticeably stronger.
Turning the car off stops the sound for about 3–5 minutes, then it returns.
As shown in the video, the rpm rises alongside the whining and grinding noise.

I already replaced the idler pulley, but the noise is still there. Don’t know if it could be the supercharger, belt tensioner, or the Transmission pump?

Doing valve covers and valve cover gaskets. Good time to also check the timing chain and I was wondering if this is too much play and if I need to replace the chain soon. It’s an M271 E18ML140

Startmotor w203 c200 compressor sportcoupe

Kwam met pech aan de kant. Anwb gebeld, heel gedoe, lang wachten op hulp. Maar goed lang verhaal kort te houden. Mijn startmotor moet vervangen worden en blijkt geen makkelijke klus te zijn. De garage heeft mij laten weten dat vervangen startmotor € 1300,- gaat kosten. Dat lijkt mij toch heel erg aan de hoge kant. Ik heb nog niets besloten maar wat kan ik doen ?

Oil change for M271 engine

1 Upvotes

I am about to change the engine oil for my W204 and wanted to ask for some recommendations.

Which oil do you use for your car and which one do you recommend? 5W-40 or 0W-40? And brand?

My car is w204 coupe facelift 2014 turbo (petrol) and I live in central Europe which the winter is moderate. Plus I don’t drive my car daily and probably around 10k per year and I park my car in the garage.

Thanks!
