Glad I could help

Hi I hope it is. Personally I don’t know if it’s the same location, but good luck to you.

Hi thank you for the feedback. Please explain which stuff I didn’t have to remove so I would take note in the future. Sorry this is my side gig on the weekend so I was working on a fly

Thank you for the comment. I agree that I know nothing. I wouldn’t be on UA-cam looking anything if I know something or everything. My video is to complement other videos that I couldn’t find to fix this car.

That could be one way you can probably change all the spark plugs back there without removing the intake manifold.

The car had around 100k miles on it and I was doing a major tuneup for this customer. The water pump was part of the tuneup. To avoid any problems of failure, such as a leak like you mentioned, these parts are normally replaced every 100k miles. I don’t wait until these things fail and plus it also creates a domino effect if left unchecked. Just to give you an idea of a major tuneup at every 100k, I normally replace the the water pump(if it’s easy access), thermostat, spark plugs, pcv valve, drive belt, transmission oil and filter (if accessible), gear oil, tensioner and idle pulley, alternator brush (if also accessible)

Hi Linda, I didn’t show the removal of spark plugs and coils because there are plenty of videos out there for that. I’m only showing my version of getting to that point. Sorry I didn’t want to make the video too long

That’s good if you didn’t have to take the dash out. It’s been 4-5 years ago when I replaced it, but I remember removing mines. Also since I didn’t have any videos to go by, I had to go on the fly and removed the dash just to have free space

Yes I did change the intake gasket. After 100k miles, rubber starts to become dry and brittle. Good thing you mentioned that because my brother told me to start doing video instructions step by step

Glad I could help. I had the same problem looking for the cause years ago and also took me months to find the issue. I had the service manual and the diagram pointed the c/opn relay to this fuse box.

Funny you mentioned that, I used all the fuses that came from the new box and kept the old as backup

I have no clue if that’ll work, but I rather keep the Brembo one piece system.

Hi sorry I am still having trouble with the codes on my dash still. I don’t know if Mercedes is finicky about aftermarket parts. Will be trying to oem and see if it fixes the problem

I’m glad I could help. Unfortunately I’m sure they engineered this way so you will bring it to the shop rather than DIY. I commonly see this in german cars. Ford and Dodge are gearing towards that way now

Hi, thank you for the comments. As far as the valve cover gasket, everything should be wide open for you to get to. There should be only a couple of bolts that hold valve cover and you should be able to take it out.

@@jann7262 hey there, just following up - wondering what size sockets (to remove the bolts) are needed for the whole job?

@@istoleyourpc6721I don’t remember all the socket size for this for this job, but I do remember 10mm socket was used for most of it and the 14mm magnetic spark plug socket. If you have the most basic metric socket kit , you should be able to do the job. Also I do use the 10mm socket that has a magnet built-in to remove two bolts that holds the metal vacuum rail I mentioned.

More power to you if you could rig the relay outside the box, but is it worth rigging with that many miles?

It's more like an experiment now than necessity.

Pcv valve is something many people ignore as part of preventive maintenance. It sometimes get clogged without knowing. I didn’t get any symptoms from the car, but can be a problem later. Google it and you’ll understand how it works

Unfortunately I don’t have a video for thermostat removal. I live in the south so I never had any issues from rust. I guess I’m always lucky.

Hi I’m not sure about the 2008. The reason I stated the year range is because this fuse box matches those years. Unfortunately I don’t know if the 2008 has the same design

T..t…t…thank you for the sarcastic response senior

Yes you have to remove the belt. The pulley I mentioned taking out in the video, you have to use that to release the tension to remove the belt then pulley come out after. Move the power steering reservoir to a side, then you’ll have more space to have access to it. You can access from the bottom too, but it’s more difficult

do you need to take out power steering pulley?

@@inee107no you don’t have to remove the power steering pulley

No code unfortunately…thankfully the car was at home when I tried starting that morning, but no luck. It took me months to find out what the problem was and also wait for a car in the junkyard

Yup. Mine didn't throw a code because it has to start first for the ECM to register a low fuel pressure errorl. The only way to know if this could be the problem is to put a meter on the pump while turning the ignition to On but not cranking. I got zero volts to the pump but the tank level sensor was fine (12v).

It’s a business move designing the relay in the fuse box. Making sure you would bring it to the shop so they could turn a profit…smh. Same goes for these new cars without a transmission dipstick. You’ll have to go under the vehicle to drain and fill only if you’re mechanically inclined

Glad I could help

Yes it’s a fuel pump relay
