cold

Hi, Bought a 2001 (W203) C200K estate 2 years ago and very pleased with it. Recently it runs great from cold but seems a bit more hesitant when up to temperature. Had some codes came up from time to time - before and after the problem. Cleaned the MAF sensor with contact cleaner and the...

I'm trying to diagnose a bad idle on my c230k, and hoping someone can point me in the right direction. Here is what I've discovered so far; Idle is bad when completely cold when warm its not perfectly smooth, but far better than when cold I've cleaned the MAF, and tried running with it...

Ok, AMG anoraks on. A few of us have commented that whilst the M156 exhaust note is louder/fuller than the biturbo, at cold start our M157's seems even louder than the M156 at cold start. Here's why, from: William Vetter Asst. Product Manager - AMG & Black Series Exclusive Vehicles...

Sorry if this is a daft question, I wondered if the engine in the CLS63 had a cold rev limit. I usually allow any car I'm driving to warm up but I'm aware my Megane 225 has a cold rev limit (4k although never hit it). Wondered if the AMGs had something similar. Also what is the cars hot...

Hi I have a E 220 cab 1994, only covered 60k with FSH having problems starting, but once started runs like a dream, sounds like no fuel but tank is full!

Hi there I'm back to MB ownership with an unfeasibly rust free 1998 W210 E240 107K 2.4 V6 Auto But...it's being a bit naughty when cold. The throttle response is jerky...on acceleration not much happens then its comes on strong, bit dangerous sometimes. This morning it seemed to hold onto the...

Had my aircon serviced on Monday by Aircon Direct,on completion the guy got a reading of 5 degrees.I thought it would have been colder but he said it was about right for MB,gave the car a run out yesterday and I have to say I wasn't very impressed,anyone got any thoughts on this?

Hi there Peeps, Any top mechanic or a person who had the similar issue as my car!, its frustrating as i got a new engine put it. one of the mercedes specialist has check it and said it the fuel distributor but that costs a bomb. other forums say its a FUEL PRESSURE REGULATOR. FYI i...

Any tips welcome ! Recently the engine is stuttering violently after starting in the morning for about a minute until the engine gets warm. After that it's fine for the remainder of the day until the next morning. Today it even stalled once /-: What could it be and what should I do ?

Why?

Hi, Noticed that the A/C is not blowing cold in my CLS W218 with the analog A/C panel. The red A/C light comes on and off when pushing the button as normal and no warning messages are displayed. Simply said, all seems well, except the air does not get colder than the outside air. When...

Hello folks. Hoping for some guidance. Got my car a year past Feb and so far it stands me around £3k so I'm hoping to be able to fix this issue myself. The car went in to get a fair bit of work done last November to a local Merc. specialist. One of the jobs was replacement of all 6 glow...

I cleaned the engine the other day on my C220 W202 1994, sprayed some water on the engine while it was running, it started hunting, when i finished i switched the engine off, dried everything out, blew all visible connections with compressed air including the HT leads and suppressors, it...

Hi I have a 2010 c250cdi estate, great car but got this annoying problem of stalling when put in D or R when the cars been stood 12 hours or more. Its been to merc on star machine with no faults found. If left running a couple of minutes then VERY VERY slowly move gear shift to R the revs drop...

Had a fault appear the other evening out of the blue. Started up as normal went to pull away slowly as the road where I park is very uneven, and felt something not right, the engine was popping etc as if it was running too weak, after about 30 seconds the engine warning light came on, and a...

My s320 has a slight whistle from the gearbox when cold. To be honest it might have always been there but I'm in the 'it's got a few miles there might be a bill around the corner' mentality now so I'm keeping an eye on everything. There are no jerks or thuds, the gearbox is behaving...

On my W203 the vents are blowing warm air on all but the minimum temp setting. I've tried doing the blower vents-reset (to no avail) and will be getting a diagnostic done mid-week, but what I have been told is that it's likely one of 2 sensors - either the temp sensor housed behind the vent in...

Hi all, OK this is a last DIY attempt to identify my only (at moment) outstanding issue on my car before putting her in the garage. When the car is started in the morning so cold at low revs the car seems to struggle to pull. If I boot it then it will not accelerate at all just seems to...

Hi Guys, I've got an issue with my Merc 1996 w210 e230 petrol. When it starts up from cold the idle is lumpy until it warms up after a few minutes, then runs fine. Acceleration is flat and slow, it has only been driven in town, but on Friday I gave it a good run on the motorway and now...
