Hi have a w203 c class 220 cdi. the coolant is rapidly leaking onto one of the belts, I can’t tell where from exactly. The car is parked at an A road petrol station. I noticed there was a problem when steam/vapour was coming out of the front of the car so stopped to check it out. i don’t...

I bought an iCarsoft V2 diagnostics (off eBay) and while it's showing me the correct error codes I've got (had it run through a STAR diagnostics) I'm unable to clear them. I've updated the unit to the latest firmware and I've still the same problem. Most of the time I try to clear the codes...

Recently moved into the countryside and need to change the front 2 tyres. Which group of tyres is best for country lanes? Can get muddy with cars cutting into the verges when it's a tight squeeze with 2 cars passing each other. Most of my driving is on these type of roads plus single laned A...

My 3month old battery bought direct from MB needs replacing (can't hold a charge, insufficient cranking amps). MB tell me if there is an electrical drain on the battery the warranty is voided because it would have killed the battery. Oh and then I have to pay for labour in determining the...

I have a series of strange electrical faults which has left the car a non-starter: central locking not working correctly (no flashing lights when lock/unlock, often doesn't respond at all, unlocks/locks very slowly) hazard lights not working on the exterior of the car, but the main button...

Going to change my car battery, but as the battery is still sort of ok, I wanted a more precise way of determining when a battery needs to be replaced. Obviously if the voltage drops quickly over time, the battery has to be replaced. But how quickly? All batteries will have a natural decay...

The original battery on my 2004 c class needs changing. Can't decide on whether an AGM battery or conventional battery is best. The AGMs sound great but I read somewhere that they don't like like engine heat (which builds up when stationary at lights when you don't have start stop technology)...

Have a flat battery, and on taking it out noticed a fair amount of rust underneath (although nothing structural). Battery isn't leaking btw.. Haven't patched up rust before so was looking for some basic pointers. Was gonna brush out the rust that's there, then use some rust eater gel, then...

my w203 c class is playing up on me big time. Now and again, the starter motor won't turn. Now am worried I'll venture out one day and will be left stranded. the history a year back the car failed to start, and then eventually breakdown recovery arrived and it started fine. I took the car in...

Automatic / diesel Started up the car, then 10 secs later decided to stop the engine to check something on my phone and can't now start the car again. Am in Park gear, starter motor doesn't make any attempt to start/turn. No malfunction displayed. Breakdown recovery guy could not detect any...

anyone had experience retrofitting a carbon cabin filter to a car which didn't have this originally? I have just bought & installed the below aftermarket upgraded pollen filter with a thin layer of activated carbon. Not sure it it'll make a huge difference given how thin the charcoal layer is...

want to install ambient lighting. Anyone already done this? the parts are cheap and it'll make the interior feel a lot more refined at night (was in a new 7 series of a mate of mine which had it and was quite impressed) I found one retrofit ambient lighting project that I quite like the...

I've a W203 C class diesel estate and pungent engine fumes (not raw diesel) are noticeable inside the cabin. Now, I know you might say this is an interior issue, but I'm convinced the problem lies in the engine (as the smell is noticeable when I'm outside, standing next to the bonnet or ESP...

I've struggled to find LED lights that I can retrofit for the Bau15s type bulbs on my W203 C class. The ones I did find were just not powerful enough Anyway, finally found some 7.5watt lights which are about double the power of the ones I tried before, but they are pricey: eg: Bau15s 581...

recently bought a w203 C220 cdi estate (thus have just joined the forum!) and a message for the B service has come up. The car only has 45k miles on the clock and from I read somewhere in the manual at this stage MB recommends a gear box / transmission service. The car is an automatic...
