rpm

In my W114 swap I cannot get the tacho working. Any ideas where i can tap the rpm signal since the "normal" green/yellow is not working. See pic. Engine is -93, 5 speed manual and non-ASR. Thanks. /johannes

Hi everyone, I do not know whether it is normal or not but my Mercedes W220 makes a whining noise in low RPM (below 2000 RPM). However, the whining noise stops above the 2000 RPM. The sound is present in both acceleration and deceleration. There is a very slight vibration when there is the...

Just a general question for forum members. What speed Is your W202 auto doing when engine is @ 2000 rpm. Cheers, tony.

Hello, My C200K has been driving me nuts. The car has around 43800 Km. It has been recently serviced in the dealer. Chassis number is WDD2040411F054615, which I have already decoded here: Vin Check. I have had two independent mechanics try to pinpoint the cause to no avail. The issue is...

Hi, I have a diesel S class 3.2 06 plate which is has some transmission issues. I am hoping that someone can help me with their experience/knowledge. The car has 140k miles and the torque converter has been replaced tt try resolve the issue but it hasn't made any difference. The issues is...

This is my first post so hope I am doing it properly I have a Mercedes vito traveliner 2003 110 cdi rev over 2500 or under load there is a serious rattle from engine or box can anyone help please This is only when driving thanks

Wondered if anyone could advise me. 1999 C200 Sport auto, seems to run fine, but from idle when you accelerate, it almost feels for a few seconds like it could stall. Have recently changed plugs and mass flow sensor as was very lumpy while driving till warm from cold which is now solved but I...

ML 270 CDi W163 2002 Auto Tiptronic: when driving and at around 3 to 4000 rpm the car just cuts out ! :wallbash: Have to put it in neutral start it up again back to drive all while still rolling @ 40 mph what would cause this shutdown ? once started again all's ok EGR is sparkling...

....but runs very smoothly up to that point. I've just redone the valve seals and have noticed now that all the plugs are in great condition (no more oiling up). Just dont know where to start as it feels like it is being starved of fuel - but experience has taught me that usually when you...

Any one used one of these free/ cheap acoustic based apps for Android phones to measure rpms. Any good? Might be a handy fault finding tool if they were any good? https://play.google.com/store/apps/details?id=org.rcteam.rcheliheadspeed&hl=en_GB

Hello people, I have the following errors but I am not sure what is causing it: P1860 - The right rear wheel rpm signal sent from the traction system via the CAN bus is implausible. P1861 - The left rear wheel rpm signal sent from the traction system via the CAN bus is implausible. How...

Hi all, I will go to a service with star, however just wanted to get some advice in advance. my 2004 ML270cdi sometimes cannot go over 2000 rpm. That is frustrating because when I need to accelerate it happens very slow. The point is it does not happen all the time. I do not know am I imaging...

Hi All, Every morning as I turn the key, prior to turning the engine, there's a great big gurgling from what seems like under the dash, very loud it is, too. Despite having had many an old merc, I've never come across this before. Possibly related is a very high tick-over of 1900. Any...

Hi, Im a little worried, we have had a 2009 c280 for around 3 months now, today my dad drove the car and he reported that after slowing down it was as if the 7G transmission was stuck in 1st or the rpm's were going up and down by themselves, the hesitation was supposedly so bad the car was not...

Hi guys first post, I have a 2001 w210 e320 estate. I've done quite a bit of reading and was convinced my issue was the MAF. I replaced this tonight with a Pierburg model from Eurocarparts but it hasn't made a difference. It's still slow to accelerate, wont kickdown and I can't get it to...

Hi... first of all hello to everyone in that forum. I would like to ask you a question regarding v6 diesel engine om642 At parking position (probably also during drive however not recognisable as ease as when car is stoped) means at N or P position when i try to slowly increase rpm at...

Hey guys, I started my c230k this morning and the rpms shot up to 2200 for about 1 second, and then back to 1200 to warm up and the back to normal idle. Initial start up was louder than usual but there was no shaking, idle hunting or misfire. It wasn't even that cold, only 15 degrees...

Hi, I've recently purchased a w211 e320 cdi and had it serviced 3 days ago at Mercedes. Since its come back it has a revving issue as if its in Limo mode. When I kickdown the car continues revving as normal ... it wasnt like this at all before it went to the stealership. I have googled...

Hello all, The last few weeks I notice when driving the car in the morning (when it is cold) the engine does not react normally. When pushing a bit of diesel on low RPM (around 1000-1200) I feel that the engine is not pulling/accelerating regularly (as it always did!) but there is a slight...

Hello everyone I have a 1995 E200 auto. Is it normal for it to be at 4000rpm when at 85mph? Its at just under 4000rpm when at 80mph. I think it may be a little high but please enlighten me. Thanks!
