1. I swear it is coincidence, but I was washing our 95 C220 then decided to do the engine bay with this power washer , well started the car, give it some good sprays, then it cut out! After that it was never the same, the idle race up and down and on acceleration is very jerky. The car is undrivable it won’t get pass this jerky stage …I’ve check vacuum lines and electrical connections all seems to be ok…

2. I had the following codes P0510, P1444, P0302 &P0300. I’ve check the vacuum lines and swap the “Purge flow switchover valve (Y27/6)” from my 600SEL with no luck, also did the same with Purge switchover valve (Y58/1) no luck with that…Even swap out the ECU (from a good C220) no luck with that…One of the benefit of having more then one Mercedes, a lot of parts are same and/or interchangeable to do this sort of thing. Did the spray starting fluid around the engine bay thing, no change or suction noted.

3. At this point I’m at a lost could it be the water? It’s been a few days now and should have dried if it was. Or did I blew something off/loose, but closely inspection can’t see anything…


Thanks in advance,

Spark plugs!!!

1. Ok the last thing I did was swap out OVP relay, that didn't help. At that point I've give-up, I've followed the books and all available resources it did not work, now this is where the experience comes in, the folks that work on these cars everyday. So I call my inde up and told him I was bringing the car in he asked me what happen, I told him from the beginning. He advised to go get some spark plugs from the DEALER ONLY R/R them then call him back...I'm like yea right (to myself of curse). I've been washing engines since High School, and never had a problem...

2. Well after the R/R of the spark plug, I start it up and it was 85% better, I took it for a test run it still jerks but very little. As I drove more and more it was better, so I disconnect the battery for the night so it can "relearn" everything, (not sure if this is true statement but did it anyways). The next morning it started fine and ran great, just a little rough shifting gears, but it was my wife's car and I didn't know if this was normal. I took it to my inde and told him what has transpired. He test drove it and said it was one of the smoothest C220 he've seen! That this model shifts like this. I came home and drove it myself for a few days just incase, so my family don't get stranded. It was running good, I gave it back to my wife and she said it actually ran better!

3. So there it is, it was the spark plugs, the water did something to them! I guess now all the codes did make sense... I just thought, what if I didn't have those other MBs to swap parts with it would have gotten expensive! :D:p:eek:Also what if I had a bad inde and he tells me to bring it in and charge me for all the parts and labor!

Rule No: 1

Avoid the washing of the Mercedes Benz Engine as much as you can. In the near future you might have to buy a new Wiring harness because the one you have in the there is now somewhat damaged.

Use a bucket of hot soapy water. Some Simple Green Degreaser and a soft
bristled Paint Brush.
Option is to use a Garden Hose to flush the dirt away.
I use the hot soapy water over all the plastics and rubbers.
The Paint Brush is to massage the dirt off the plastics, rubbers, cracks, crevices etc.
