Hello Guys, W203, 200 diesel. Car drives as normal, but switching key to position 2 starts an electronic knocking sound coming from the bulkhead area which lasts for about 20 secs, whether engine is started or not. Similarly, knocking (about every second) starts and lasts for about 30 secs on...

Hello Guys , W203 200cdi, `54 reg 646 engine. The EML light is on and my tinpot diagnoser tells me the problem is solenoid voltage /turbo actuator. so I deduce that the actuator is probably a Hella electronic one. I`m getting a bit long in the tooth for car fettling these days, but...

Morning Guys. W203 facelift, OM646 engine. EML light on and diagnosis reads " P0123 throttle position sensor `A`circuit high." Anybody have experience of this? Where is this sensor? On the intake manifold? Near the pedal? Any pointers appreciated. Thanks for reading.

Just back from a couple of weeks in Madeira, and noticed that Mercedes, once dominant in the taxi business are losing out big time to Renault with their new Meganes and boxy Dacia estates. But what was more mysterious was the fact that during the whole fortnight, I never spotted a Merc taxi...

Accidently, I have found that my old W203 220 cdi starts after two or three revolutions even on these frosty mornings if it is parked slightly downhill. Suggesting what ? Usually, in these conditions, it would need three times that.

Hello Guys, Anybody had this fault - A few weeks ago, up popped a message `3rd brake light. Check lamp` . I knew that only about a third of it worked, but SWMBO stood at the back and reported total failure. I replaced it with a new one off ebay, probably Chinese. but still no joy. I removed the...

Hello Guys. Can anybody on here clarify just when and how long the dash glow plug light should be lit, when I start my W203 cdi ? At the mo., it flashes up for about a second, when I switch to posn. 2, then I turn to cranking posn. 3 It needs an extra crank or two, now the early morning...

Hi Guys, Anybody know off hand the year MB started installing DPFs on W203 diesels ?

Hello Guys, W203 pre facelift. It started with the window working when it felt like it. Then it stopped working altogether (luckily closed) I unclipped the door card, and without de-hooking it. stood it on a box on it`s end. Suspecting switch failure, I unplugged and removed the switch...

My W203 is covered with a 3inch layer of snow at the moment, but today I noticed a 6 inch dia. melted hole in the snow directly above the interior mirror. Is the interior mirror heated ?, and if so, can it be switched off somewhere. The car is sorned (due to Covid) but I am having to trickle...

Morning Guys, Just wondered if there is a general consensus about releasing fluid that is better than WD40. If any !

This tale may, or may not be of interest to W124 diehards on here. Way back in `87, when I was ordering a 190D from an MB dealer in North Yorkshire (nearly a 1 man band), we were chatting, and he happened to mention that there were 3 W124 200Ds at MB Milton Keynes. He sensed that I was...

Now that the weather has gone noticeably cooler, I noticed lack of warmth inside my project W203 cdi, and have decided that the thermostat must be stuck open. Looks like it is located front, top, left side of the engine, but is surrounded with fuel pipes, wiring tubes etc. Probably the oil...

Are early W204s having rear subframe problems? Two adverts recently read, state new rear subframe required. One ad. suggests control arm broken away, whereas the other ad. states subframe cracking, and then adds `common problem` Any reports? before I start looking.

Hi Guys, I`ve recently re-entered the MB world with an 03 reg. W203 2.2cdi. Clonking at the rear has (so far) revealed a completely snapped- in- two Thrust control arm. Looking at Fleabay ads, plenty mention torque/track control arms, but thrust, no. Please can someone on here supply the MB Part...

Hello, Anybody on here know whether car/ Vin Nr, WDC2030082R202652 will have a simplex or duplex camchain. It`s a C220cdi. Many Thanks.

Hello there, I`ve read horror stories concerning camdrive chains stretching/snapping etc. Cdi 200; 220, 270 engines. Which are fitted with a single chain and which are fitted with a duplex chain? and which years if changes have been made? Still running my trusty e300 td (duplex); but `er...

I decided to smarten up my W210 300td before getting it back on the road. It needed the obligatory new wings, which weren`t much of a problem, and now I`m at the painting stage. What I thought would be the easy bit, ie, gunning them over with some cellulose, is turning into a nightmare. I...

After warning her about Renault electrics and anything else I could think about, SWMBO seems deternined to buy a Megane tin top thingy.:doh: Although the seller is not exactly a back street garage, but because we haven`t bought a car for a few years, I need some up to date tips to avoid some...

Hi Guys, Any of you familiar with the transmission layout of an automatic 924S? Is the torque converter with the rear transaxle? Or in the engine bellhousing? What about the ATF cooling pipework? :( Any info welcome. :)
