    1994 w124 estate 280 poor fuel economy

    Update/ issue resolved!! for Poor MPG To be fair to me, there were no symptoms of the cause whilst driving the car when i started the thread...but the issue was...piston in rear calliper sticking, causing brakes to be lightly on. It came apparent when the brakes wore out. So a new set of EBC...

    1994 w124 estate 280 poor fuel economy

    That Sensor connector in 1894.jpeg is different to mine thats a 4 wire version, and I see there isnt the lower sensor. My set up look more like grobers photo ie with the spare 2 wire connector, but as i say without the sensor... Perhaps I need that sensor for my AC to work, and maybe the lower...

    1994 w124 estate 280 poor fuel economy

    Hmmm the plot thickens...My car also has A/C but as yet I have not been able to get it working. It has had a full service and has passed as mechanically sound, but sensor/ control issues were suggested as to why it wouldnt work...the recirc button flashes on and off... I wonder if it is related...

    1994 w124 estate 280 poor fuel economy

    No, nothing on roof, and economy of e320 was something i lived with/ got used to, my issue is that the e280 is far worse than the e320. Wiring loom was replaced a month ago, I ordered it using the chassis number. it arrived with the extra connector available to use. Ill post a photo in a mo...

    1994 w124 estate 280 poor fuel economy

    So My 300mile round trip (which I use the same roads every time) was mainly motorway/ clear roads, no urban. My E320 on exactly the same trip would achieve approximately 30 MPG. Ive read a couple of over topics similar to this, most people report to getting close to 400mils from a tank, which...

    1994 w124 estate 280 poor fuel economy

    earlier this year I had to retire my 1994 e320 due to rot through out the car after 7 years and in my use 70k miles. Not bad for a car that cost me £1500, and that made me realise that the replacement had to be another W124. So I found a 1994 e280 estate with 150k miles on the clock. The car...

    1994 W124 e280 coolant change caused poor running....

    Ok Update to issues above Engine had head gasket issue and engine wiring loom issue. The poor running was almost certainly the head gasket. So bit the bullet and got it done, the car is otherwise sound with very little rust. At the same time I upgraded the after market air con set up at the...
