I got notifications that Dustin was coming. I could see his travel to my home. Dustin was on time. He was very pleasant. Dustin informed me of the problem he fixed and showed me also. If I have another problem, I would like to request Dustin again!

Robert is five star. He called before he came to see if had any questions and to confirm that all was a go for my Mercedes 60 thousand mile check up on the following day... He arrived in a timely fashion and went right to work after he once again very thoroughly answered my questions about Your Mechanic, the company. He worked diligently for more than the 3 1/2 hours and cleaned up his work area to the condition my garage was when he entered. (Which I greatly appreciated) Robert informed me of one worn brake pad that needed attention in the near future and a need for a flushing of a fluid also... I was impressed with his professionalism and look forward to future mechanical work done by him...Thank you Your Mechanic for connecting me with Robert...

Answers to common Mercedes-Benz 420SEL questions

Q: Car running sluggish then dies - 1988 Mercedes-Benz 420SEL
Answered by Robert
Hello. I would check the fuel filter (https://www.yourmechanic.com/services/fuel-filter-replacement) first. If the filter is clogged then this will occur. If the fuel filter is fine then the air flow meter needs to be checked. This is the most common part to...
Q: Car will only start after being jumped - 1991 Mercedes-Benz 420SEL
Answered by David
If this is a fuel issue, it's likely the check-valve in the fuel pressure regulator not holding pressure during shutdown. This valve keeps a low pressure in the fuel injection system for faster starts. If faulty, the fuel pump has...
Q: No fuel to pumps - 1991 Mercedes-Benz 420SEL
Answered by David
Since you know how to use the multimeter, you are 2 steps ahead already! Start with power to the fuses (fuel pump), then the fuel pump relay to follow the power path. It's also possible that the ignition switch (https://www.yourmechanic.com/services/ignition-switch-replacement),...

Trusted by thousands of happy car owners



I can't say enough about how pleased I am that I found YourMechanic and Raul. I'm from out of town and didn't know who to contact to fix a truck I was borrowing. I searched the web and found YourMechanic.....thank goodness. I found Raul to be professional, an outstanding mechanic and the price was more than fair.



Kevin showed up ready to do his job and did just that. He showed me a couple important things on my vehicle I had overlooked and was nothing less than incredibly professional, knowledgeable, and informative. I would, without hesitation recommend him to anyone I know and would gladly use him again.



Tom went above and beyond to make me as satisfied as I could be. His communication was excellent. Friendly and professional and best if all, my car is running great and he did it without unnecessary repairs. I would and will highly recommend Tom and Your Mechanic to everyone. Thanks, Rob Miller.
