Is it hard to add ASR Off switch?
Naperville (mboemparts) is good for OE/dealer stuff, especially with the free shipping deal for forum members. AHAZ is ok but they have been carrying more junk brands and fewer good brands (click here for list). PeachParts is a good vendor as well, along with FCP Euro, whose claim to fame is lifetime warranty on all parts.
Unless the head gaskets have a severe leak, just ignore it. Parts & labor for head gaskets on the M119 is innnnn-sane.
Remember that ECU upgrade only improves full-throttle power. Any perceived power gain at part throttle is due to other differences, not the ECU. You can get temporary FGS by moving the shift lever to the "B" position while stopped, then moving it back to "D"; the trans will start in 1st once when you do this. Repeat as necessary.

If you are an electrician, it's just a nuisance to install (very short wire length available under the CAN modules). Plan on 3-5 hours as a first-time DIY.Is it hard to add ASR Off switch?

I've been using mboemparts (MB Naperville) for all of my factory parts orders in recent months, and the free shipping offer for members of this site is FAAAAANTASTIC !! They are very easy to deal with, have a much improved web site over the old "parts.com" days, and their shipping is just as fast as ever. I usually have everything in 4 business days after order. My most recent order was a big load of spark plugs and two "PREMIUM UNLEADED GASOLINE ONLY" decals for my C126. The decals had to come from Germany, but the order was still received in 5 business days from order.
There is a Schrader valve under the metal cap on the fuel rail. The washer is an extra safety. Best to let the car sit overnight to let the pressure drop to zero before messing with it.I was looking over my engine and saw some moisture on the fuel rail upfront under the first plastic cover. I think the washer is causing a leak . Jw if that line is fully pressurized or is it safe to unscrew the nut and replace the washer ?

Are you sure the moisture is fuel?

Yup, that is the stock 1994 LH module, with stock chip... correct for the car.Ok good to know, It smelled like fuel. I started the car let it run for a couple of min then went to check under the cover and noticed it. I just checked my lh to see if it had a stock chip this is what the chip read. 2 287 358 442 . I pulled the Bosch 0 280 002 569 unit I think that is the correct one.

In your pictures, I noticed that the trim framing the rear back glass as well as the trim that runs front-back along the two sides of the roof look to be black. On my own pre-facelift car, these have a brushed/anodized aluminum finish to them. Did a previous owner change the look of these trim pieces or is this how they they came on facelift cars?
until just a few moths ago. My least favorite thing t do is remove door cards, so I gave my tape a try. It took 10 minutes, a little precision xacto knife work and all of my trim is black instead of bronze. I have matte tape, but it is 20 for matte and 21 usd for gloss. I stuck with matte for the side window since the other will fade to matte. Consider this a public service, no affiliation Nice. The two-tone upper/lower color combo of the smoke silver color theme on the W124 makes the car look so much better, IMHO, than the 1-tone-smoke-silver color combo on W210 cars.

Also - I lived in Chicago for many years --- geez your pictures reminds me I am sorry --- I don't miss the white stuff or the cold!![]()
Thanks ya its very sharp until I can afford amg oz
Just be sure you remove the panel and inspect all the connections and rubber hoses. New copper crush washers are a must for the filter and banjo connections. Unscrew Gas cap and relieve pressure, and keep car outdoors for ventilation. There is also a check valve coming off the tank for pollution control. It may need changing, and the rubber lines I mentioned may also be cracking under pressure.
Do not drive the car until you locate the leak source. The most common failure is the high pressure hose exiting the fuel filter, but look at the large feed hose from the tank as well (and, the fuel pumps too).Hey guys today was my first time I got to take the Benz out legally in Chicago and with good weather. I noticed when I started the car and went to install my temporary plates there was a very strong smell of fuel coming from the rear of the car. I inspected for leaking fuel but there was none? I am going to order a oem fuel filter and change that and inspect the lines from there. Anyone know of this issue.

If the fuel smell is from INSIDE the car, not outside... that is a different problem.

Those hoses at the fuel pumps and fuel filter are closing in on 25 years old. You need to replace ALL of them. As well as the feed and return hoses under the hood. There is also a fair bit of corrosion in the photos.
As I've stated in other posts, faulty fuel lines are one of the most under-noticed and under-replaced things on these cars. I have had two cars (a 1989 560SEC, worked on in 2010; and a 1995 E320, worked on in 2014). In both cases, the fuel lines were visibly cracked and degraded, and only a short matter of time until both would have failed and spilt fuel underhood.
Don't chance it - order and replace the fuel hoses. 25 years is well beyond the service life of rubber items !!!
If you smelled raw fuel, it came from somewhere. You should keep trying to locate it. Don't want to have a very rare 036 flambé...Ok so I got under there took the cover off and there was no sign of leaks

I would only use the OE/dealer hose for the high-pressure hose exiting the fuel filter. I haven't personally seen the Cohline hose currently available via aftermarket... but I don't have the slightest confidence it's OEM, and IMO it's not worth saving $50 to risk a $20k car fire. Replacing the tank feed hose is optional if it's not cracked, but inspect it closely for cracks... they can be hidden on the back side and difficult to see. Click here for pics of the cracking feed hose.Is Cohline acceptible for the fuel filter to feed line ? Fuel tank to pump I only see the dealer option. I am having trouble locating part numbers for the rest of the hoses you are referring to .

The 036 does not have fuel hoses underhood which crack and split, Gerry was referring to different models (C126 and S124). The 034/036 have stainless braided covers on the engine compartment fuel hoses and so far, nobody has reported a failure of these. Which is good, because I believe they have been NLA for a while.
If you shell our for new caps+rotors, get new insulators too. Cheap insurance, lots of threads about this.... Next in line will be cap and rotors.
If the ASR light on the dash came on during this time, you experienced standard limp mode... throttle will respond if you push the pedal all the way down. Need to check codes to see what may have caused it. Have you looked at the date code on the ETA yet? If original, it's on borrowed time.When I was on a straight away and accelerating the other day the car went into a weird limp mode. The throttle did not respond at all and I had to pull the car over and restart it and then it was fine.
Running on 1 fuel pump won't cause limp mode, but will cause a power reduction during the time the 1 pump is not working. When this happens, no codes are triggered at all.I was reading one of the threads that says something about running on one fuel pump which may be the case. Its only past 80mph does the car react this way. It happened only twice.

See attached.Where is the date located ?
That will only work if you have a 38-pin breakout box / mushroom adapter - which is recommended, as it makes things far easier than using the blinker box with 1mm pins designed to work directly with the 38-pin connector. Details in this thread, see attached pics in the first post:Also is this blink code reader ok http://www.ebay.com/itm/Mercedes-OB...-201-300E-190E-E320-300TE-300CE-/231620869425


Yep, that's the original ETA, Jannury 1994. If you frequently get limp mode (ASR light on, reduced power, extended pedal travel, temporarily cured by re-starting the car)... replacing the ETA is likely to fix the problem.
That vacuum line goes from the rear bottom of the intake manifold, out the front of the intake along with the 8mm black PCV tube, under the driver distributor covers, and over to the EZL on the driver fender. You are likely to find all of the vacuum tubes in the engine compartment fossilized and breaking if you look at the wrong, including all the PCV hoses atop the intake manifold to the valve covers. They should be soft rubber. If they are rock hard, plan on replacing all that stuff... and the black 8mm PCV vent tube as well. As a temp fix you can try to patch the busted vac line but don't be surprised if it breaks again while trying to patch it. There's a detailed thread on the forum with all the PCV tube p/n's if you need them, they are another dealer-only item.

Nobody has proven any real performance gains from ETA mods. There was one guy on a different forum years ago but we never saw any proof via dyno runs. Stock ETA replacement is ~$1k for factory rebuilt if available, a bit less for Beckmann rebuild, or $300-$500 for a used late-datecode ETA.I saw a forum member had an aftermarket performance eta installed, im assuming those run around 300 to 500.

Thank you !Benz: I have been following your new car thread-- good luck with it. Very nice color! Looking at the pictures of the fuel filter & pumps I think you're missing the plastic sleeve on the filter. Lower pump has a blue colored sleeve clearly visible. I don't see one on the filter.
