Question about 2001 Mercedes-Benz C-Class

Need Help with recently bought car

Hi all, I bought a 2001 C240 recently (108k miles) (on 19th Jan.) from a local car dealer for $6000. I took it to the local Mercedes dealer for inspection and they told me there're plenty of things wrong with this car. The main problem they listed are: Rear Main Leaking Valve Covers Leaking Motor Mounts and Trans Idler Beltand Tension Miss fire in two cylinders (3 & 6). They told me that it would take about $4200 to fix all of these problems except miss fire in cylinders ( they need to do more diagnose in order to find out the real cause of miss fire in cylinders). The primary reason I bought this car was to drive from home to University and for daily chores. I am not sure how serious are these problems and what should I fix first or should I keep running the car because I just need to drive 15-20 miles a day. Also, do you guys think is it worth spending $4200 on this car or not? Thanks

Monitor oil leaks: keep fluids topped up. Consider repair if the leaks are major.

Replace / Check: Idler tensioner - if this belt breaks you won't have cooling and the battery won't charge.

Miss-Fire: find the root cause and remedy poor fuel economy and can damage other components like the catalytic converter and these are not check to replace.

Don't spend $4200 with Mercedes - find a reliable mechanic who will do the work at a more reasonable cost.

I have to assume that the car looked & drove well when you bought it otherwise it would still be on the lot. I think $4200 seems a bit steep - The dealer you bought it off may be able to recommend a mechanic see them first but if not them certainly see another mechanic other than Mercedes - if you don't have a mechanic you trust head towards a larger franchise business in Australia we have places like UltraTune & K-Mart.

As far as what I would tackle - I am not sure what "Leaking Motor Mounts" - but I will assume there are some leaks - I would be guessing minor ones from the motor. Even though they may sound bad they are probably your lowest priority if they are small you do need to keep an eye on them however and make sure your fluids are kept topped up.

Get the idler belt checked - they can be a pain to try to do yourself get the belt replaced. Then look at your miss-fires. Have new spark plugs put in regardless (is my opinion). See if there error still persists if so then most times it is ignition coils that is the problem a mechanic can check this by swapping the 3 & 6 coil to other cylinders and see if the error moves, replace the affected coil. If the error stays on 3 & 6 it is likely blocked / faulty injector. (This is AU pricing) indicates that you bought within a good price bracket.

I can see if I can find more prices these are ALFA ROMEO prices (indicative). Ignition Coil: $150 - $250ea; Spark Plugs: $15ea; Injector: Service / clean remove / replace: $600; New Fuel injector: $300. Labour in AU charged by mechanics is around $95 - $180 per hour.

SOURCE: 1993 mercedes sl300 convertable

The early 300 SL suffered from dodgy HT leads and spark plugs if not regularly maintained, the problem with Mercedes Benz though is that the cars have so many features that it is almost impossible to diagnose without seeing the car. Some things to try (in this order) are : - Spark plugs, Ht leads, remove and clean Distributer Cap, replacement of HFM sensor (common fault), if none of these help then faults have been known in throttle valves and fuel pumps/filters

Happy fault finding

SOURCE: 1993 Mercedes Benz 300E, right rear squeak

Common causes for High-pitched noise from rear wheels are:

The wheel bearing: this is not usually dangerous in the short term, but I recommend contacting a mechanic and having it fixed. To test the wheel bearing, you lock front wheels, and jack up the car rear and spin the wheel (handbrake unlocked). If bearing is worn you hear a drone. When is the bearing, often car starts vibration above 40 mph.
Noise from bearing can be continuous, intermittent, only when steering, only when hot.

The brake pads: when brake pads are worn out they start making a squealing noise, in this case the noise is only when you brake or continuous. When you jack up the car the wheel may be a little stiff, but not necessarily.When brake pads are completely gone you also hear a scratching noise when braking. Inspect your brakes immediately.

Other suspension problems: Jack up the car as suggested above, check if the wheel has a slight play on the sides. Check all of the suspension components, suspension mounting points, and steering linkage for damage. Also, check the frame rail for wrinkles. It is very important that these components be in good condition, if you notice any problem here, go immediately to a mechanic.

Try doing the simple test above, reinstalling the wheel and working the tire back and forth. This is a common test for bad ball joints and wheel bearings.

I recently bought a 2003 Santa Fe. It's burning a quart of oil every 1,000 miles.

If you do some more research you'll see that 1 Qt per 1K miles is considered acceptable, as the dealer stated....not that I agree either!

You may try replacing the PCV valve and ensuring the valves are adjusted properly.

Also, try a different oil - maybe a different weight may help.

I WOULD replace the O2 sensor as it can affect the amount of fuel that is used and may actually dilute the oil if it's getting past the rings.

Just to ensure the engine is healthy you can get a Compression and Leakdown test down. This will tell you the 'health' of the engine.

Go look on the Hyundai/Kia forums for oil consumption, too. You might come across something specific to your model.

I have an internal transmission problem in my 2001 Odyssey.

My wife and I are just resolving this same problem. You need to request a copy of Honda Service Bulletin # 02-062 which is titled "warranty extension: Accord, Odyssey, and Prelude Automatic Transmission. The warranty is for 7 years nine months or 109,000 miles. You are with in both of those aspects. Your dealer should have informed you of this and your transmission is should be completely covered with a replacement that should have an additional 1 year of warranty and 12,000 more miles. I took this issue to Honda America direct and they are in the processing of re-imbursing me for the cost of our transimssion repair.

Volvo V70 t5 Shift to Transmission cable broken

Seems excessive for just a cable unless the transmission has to be removed and dismantled.

I suggest you check with the dealer for costs and parts availability and the dealer price would typically be the most expensive quote for your guidance.
Then you should ask at least a couple of local transmission specialists who would typically be 30 - 40% cheaper.
