flow

What is the conventional wisdom on porting, polishing flow testing an M104 head? Will it make much of a difference form stock, or is it really a lot of money for little gain? My head gasket needs doing and I was wondering of this is something I should consider having done at the same time...

I am told i can test the Air Flow Meter on s 320cdi by starting the engine and disconecting the plug to the air flow meter if the engine tone does not change the meter is faulty, if the engine note changes the meter is ok Can anyone confirm if the answer is yes which plug do i disconnect the top...

Re. W203 220 CDI On this engine, a clear plastic pipe runs between the HP injection pump and the bulk-head end of the common-rail (just before the pressure regulating valve); anyone know in which direction fuel flows in this line?

Hi does anyone have a w202 c180 air flow meter which they want to sell? Thanks

Hi, I have a 99 C250TD on which I'm doing a conversion to run it on vegetable oil. I have a flat plate heat exchanger to fit in parallel with the heater matrix so that the it is permanantly fed by hot coolant, but with all the duo-valves etc I can't work out where to 'Tee' into the coolant...

Hi guys, I've seen a few guides on how to clean the maf sensor for the clk 430 but non for the clk 230k :(, the clk 430 has an airbox whereas the clk 230k doesn't where can I find the maf air flow in my car? As I want to clean it so I can fix the issues below. My car is currently causing...

I posted a ...er..post regarding my c200 and the general(and much appreciated) opinion was change the MAF so today (I had to save up) I bought a new probe and fitted it...well it has made a difference! the car does pick up and go like it is receiving fuel, if you hit the throttle it hesitates...

HI all, thanks for letting me join - my first forum so please bear with me. I have E200 kompressor estate 2004. Always had mercs but this one is my first petrol motor for quite a while. Have noticed when the blowers are on with the air con I get a low dronning noise coming from the engine on...

Hi I need to replace my MAF. The dealership want nearly £200 for one. I can get a Bosch one from Euro car parts for £115 delivered free. Does anyone know if Bosch are the original fitment? My car is a sl320 (2001). Cheers

Hi, I own a M reg w202 c180 sport (MANUAL) and i need to possibly clean/replace the maf unit due to shoddy idle But i cannot find it. I thought it should be between the air filter and the throttle body but there is only a two wire sensor?(what is this?) can anyone supply the location of the maf...

Bosch Automotive Tradition - Parts - Current reproduced products Very welcome news for the older MB owners amongst us :o No idea on pricing/availability etc, but I imagine a local Bosch agent/service centre would be able to advise :) Will

Hi, Have noticed over the last few cold mornings that the air flow from the rear air vents (in the centre console) appears to be a bit on the pathetic side! The front vents can be belting out hot air but the rear ones have a minimal flow - almost as if the fan is only set at 2 rather than 6...

Recently, my car was behaving very strangely as the engine is stopping while I am driving, especially after I am changing the gears or slowing down I have taken my A160 car to my local mechanic and he plugged in the diagnostic meter and found out that the mass air flow metre is faulty. Can any...

Hi, A newbie here,I've got a great 2000 x reg 240 estate, I covered over 30K trouble free miles in the last year, its the first merc I've owned and I doubt i'll ever drive anything else. I was spoilt long before buying it after having use of more exotic mercs when I was working with a well known...

Hi all I have no airflow coming from the centre air vents -neither hot or cold. The side vents work fine as do all the other outlets - any ideas please?

I hear that Bosch have just sold their last Air Flow housing, from the UK stocks £350. This one was for the 300E/TE where the idle is erratic and surges due to wear on the pot. Its unclear at this stage if there will be anymore. I have heard that its possible to fit a different pick up...

Just changed the return pipes - What a bloody job that was. Had to remove the air intake manifold plus a bloody plastic cover before I could get at them. When I saw what was under the plastic cover I thought sod it I'm buying a horse. Each of the six Injector rebates was full with diesel and...

Very easy to do even though I was having a mild heart attack at the time! So, now changed and my car is nearly 100% again - but do I need to have the ECU reset? I noticed that the car was a little slow responding to the new MAF but after a few miles of driving slow - gear changes were...
