Coolant leakage into engine

[Cptay]

Greetings,

My wife owns a A200 for more than 3 years. Recently, the top-up coolant and coolant temperature warning signals started to appear on a daily basis. We sent the car to cnc for repair, but guess what, the problem was not solved. We sent the car back to cnc again, but cnc said they could not spot any leakage and advised us to observe for few more days. Needless to say, we have to send the car back after a week. This time, the car stays there for more than 10 days. Eventually, after many phone calls, they get back and claim the coolant is leaking into the engine. They have difficulty suggesting a good solution for us. I was told the best solution is to change the engine! This is ridiculous. The next solution mentioned is top overhaul. With my limited knowledge, I can only suggest them to check the coolant tank cap and the head gasket. Replacing the engine is stupid. I have no idea why they are taking such a long time to troubleshoot, and leaving the customer in the dark for so long. Just simply not acceptable service from cnc. My wife is very disappointed with cnc, and wants to go back to Japanese built.

Can anyone here advise us what to do? What's the expected costs? Anyone with similar problem?

Regards

I had a bigger problem with leaking coolant as well. Found there was a crack on my C180 coolant assembly (plastic made) and was advised to replace it and at the same time replace some hoses and a major component - coolant/engine oil assembly. Damaged SGD 1700. I was told by the mechanic, that I am lucky to drive the car straight to them asap, otherwise there will be more damages. All this was done at a shell station near boon lay.

Guys,Juzz be mindful .

The Later Mercs always seems to have a Coolant issue .

Every morning Before u Starts yr car ,open yr Coolant expansion tank & Check ?

if it’s Low ,Be alert ,u can top it up with water & monitor the next morning .

when u go for yr Servicing .Try to do it at 10k or or Below.

Ask the Mechanic to check the Coolant pump for Leakage.

Dey have changed to the Electronic Coolant/water pump for the newer model .

Theres a Recall for dat.

OMG …………

Routine checking is the Best solutions now.
