Hello all.
just a quick introduction. i don't know what happened to me, but after a visit to MBWorld in Weybridge i think i must have contracted MBitis and have still not recovered. i assume that there is no cure, especially as one gets older, it seems. Unsatisfied with a fantastic 300CE...
Evening all,
i have a 1991 R129 300 SL-24 and have been incurring intermittent faults which cause the car to die and leaving me stranded. When trying to re-start the car it fires briefly on first attempt and then dies again. It can be a couple of days before the car starts again without any...
While answering a thread elsewhere ;) I came across these diagrams/pin assignments for the large MAS relay found on some early w124 and w129 models.
These don't appear often so I decided to post em up here
MAS relay diagram - PeachParts Mercedes ShopForum

I'm running a '96 C180 Auto estate with a mere 208,000 miles on the clock. It started pinking and was noticeably sluggish so having searched the forum, I took it to the local garage for a diagnostics check and they confirmed it needed a new mass air sensor. I fitted a Bosch unit and the engine...

Hiya,
Sooo fed up with the Merc these days, any advice on the problem below would be great thanks.
The car has been running rough recently, with my Mrs saying that its loosing power. In the past I have replaced the mass airflow sensor twice over a couple of years, seemed ok to me, but I drive...
My E class has been getting slower and slower so having read the various MAS/MAF posted I decided to get a new one from the Mercedes dealer. Fitted it last weekend and the car was better but still not as it should be.
If I floor the accelarator it kicks down but will then change up at about...
Can any of you MB Tech guys advise me on how I remove the MAS so that I can inspect / clean it. Looking at it, I do not know where to start. :confused:
Can you Tech or Indie guys confirm if this is the MAS on a 203 C240 V6 ?
Have marked each pic with a red arrow, where I think it is.
I have searched the history threads for info, but all seem to be on the C240 Sport, which appears to be a different engine set up entirely.
If so, What items...
I had a new MAS fitted at a recent B service and the car ran like new with lots of oomph, then after a couple of days I suddenly had the old problem of having to drive like a granny and any attempted hard acceleration resulted in severe sulking from the front end (no power and no change up).
I...
I substituted the Bosch part in my C240 with the Pierburg part from my straight six S320 cdi to diagnose poor running problems!
Referring to the "How to" here

I am a little confused as to using the Pierburg MAS as a replacement for the...
Morning all,
I've noticed over the past month or so the following occasional unusual behaviour by my car.
Very harsh gearchange to first - usually following a high speed or high rev run. For example, pulling off a motorway onto a slip road and stopping at a roundabout, the gearchange into...
I own a clk320, and its that time where i need to change the MAS, as at times it loses power and the car starts juddering.
Now i know this part is easy to change so will do it myself.
What i need help with is the fact that german & swedish/ euro car parts are charging £140+VAT
And mercedes...
I have had a problem with my W202 for a few weeks where in the morning, especially when it is cold it mis-fires a lot and there seems to be a complete lack of power until the car warms up. Having read some threads on MAS problems I disconnected the MAS unit (un-clipped it) and like magic the car...
My car has started to show the faults that seem to be common in mercs ie the MAS is on the way out. After reading the haynes manual and having a quick look under the bonnet i cant see it. I was wondering if anybody could point it out for me. I have attached a picture of a merc with the same...
