Manufacturers scheduled servicing for 5 years probably means the brakes have never been properly looked t - wheels off fettling costs little but can save big bills for sticking pads, sticking calipers, pitted discs - new pads, discs all round = £600+ even on a modest 5 year old car.

Water pump? I have cars for 54 years & never needed a water pump on any of the cars I owned.

At 5 years old the car may need far more than an oil change. Don't base your decision purely on one year's use.

Items such as fuel filters, brake and clutch fluid, spark plugs, gearbox oil, cambelt, water pump may need changing. You need to look at your servicing schedule booklet for the details of the work required each year.

Well I didnt give much information about the car because the original post was more to do with the disappointing response I got to the Ask HJ question.

Regards the car, no, really it shouldnt need a change of all those items because it's been fully serviced on time at the main agent since day one. Always providing the dealer has changed said parts even though there's low mileage between services!

Actually it was the faulty EGR cooler valve causing the engine to overheat, resulting in the warning light coming on and requiring the engine to be switched off immediately. A well-known, but denied, fault with M-B diesel engines in C and E-Class cars made between 2010-2013. While this was being investigated, the garage also found that the water pump was also in bits. So resulted in a bill for more than £500. Bazomis

So not really "coolant problems" as such..

Also you seem to imply above that an EGR valve retalls at 1.40. If that's true I need to get myself a Merc, (The NeoLada For NOW) to cut my parts costs.

There is undoubtedly a lot of good info on't Internyet, but there is also a lot of utter t***, and I seem to be encountering a lot of the latter in a Honda Accord EGR context, perhaps because there are a lot of them in America, and its complicated enough that t*** isn't so readily detectable.

A couple of examples

"Vacuum Issues– The EGR valve relies on engine vacuum to operate."

No it doesn't. Its an electronically controlled solenoid.

"Sensor Issue– The Differential Pressure Feedback- EGR sensor can go faulty and cause the EGR valve to stop operating properly and throw the code."

I don't THINK Honda's have DPFE sensors. I THINK that's a Ford thing. This looks like lazy cut-and-pastery, something I see a lot from students.

While trying to confirm the latter point I came across this

The answers take misinformation to the next level, being apparently unrelated pastings from workshop manuals.

This seems to be malicious. I can't see what the posters get out of it, but then I don't really understand spam either.

Be careful out there.

A well documented fault with the EGR system on many cars is corrosion of the EGR cooler-it's a heat exchanger that is cooled by coolant, exhaust gas passes through this to be cooled before being introduced to the inlet manifold via the EGR valve. When the cooler corrodes coolant leaks out into the exhaust, so low coolant equals overheat.
