Mercedes Gearbox Repair FAQS

What kind of problems are common with Mercedes automatic gearboxes?

There are a number of common issues with Mercedes automatic gearboxes, which we are well equipped to handle. However, issues with the Speed Sensors housed within the electro-hydraulic control module are some of the more common faults in a Mercedes automatic gearbox.

Will I need a new gearbox if it’s slipping out of gear?

You will rarely require a new gearbox if you find it is slipping out of gear. A fault like this can be caused by any number of reasons. At DDR Surrey, we can diagnose the issue using the latest equipment, repairing and replacing only the parts that require it.

Will I need a new gearbox if it’s leaking fluid?

You should always get a leaking gearbox repaired quickly. A leaking gearbox could be caused by a number of issues that usually only require a minor repair and ignoring the issue might lead to further damage. We would need to see your vehicle in order to correctly diagnose the issue.

What should I do if my Mercedes automatic gearbox isn’t working?

If your gearbox isn’t working or switching gears as you drive, this is a sign that something may need repair. Get in touch with our team, who will run full diagnostics and repair to get you back on the road as soon as possible.

Why is my Mercedes gearbox making strange noises?

If your Mercedes vehicle is making grinding, clunking or other unusual noises, this could be a sign of wear and tear. It’s important to get your vehicle booked in for diagnostics as soon as possible.

How do I know if there’s something wrong with my Mercedes gearbox?

If you’re hearing any unusual noises or if the gears aren’t switching smoothly as you drive, your automatic gearbox could need repair. We have the latest technology to help you find the source of the problem and repair it accordingly.

Do you service leased or financed Mercedes vehicles?

If you have a leased Mercedes vehicle or a Mercedes on finance that you plan to return at the end of your contract, you need to keep on top of service schedules. Failure to meet the suggested service schedule could see you facing fines and penalties at the end of your agreement, so it's vital to maintain the correct schedule. We offer full servicing to all Mercedes vehicles including leased or financed vehicles, helping you to keep on top of your service schedule and avoid any hefty fines or payouts when your contract ends.

I’ve had real trouble getting wiper blades for my Mercedes I tried Halfords which was an absolute shambles from start to finish! Found DDR on google and called to see if they could help had a call back within 5 minutes of leaving a message to be told they could have them in that afternoon and the exact price which I might add was cheaper than I was charged at Halfords! I arrived around 4pm new blades fitted in 5 minutes the customer service of the gentleman I dealt with was fantastic I will definitely be returning. Thank you again for your help.

Started using DDR last year, now two years in and I can only heap praise on Dan and his workforce, Dan a man after my own heart, his word is his bond and nothing is too much, great service, highly recommended.
I have been coming to DDR for over 8 years to have my Wife's E350 Cdi serviced. I have always found the owner and staff to be friendly and honest. I started using them after suffering truly abysmal service from more than one Mercedes main dealers. They have diagnosed and fixed various faults on the E350 over the years. I just took my '03 SL55 AMG for its 2yr interval A service, plus a gearbox oil change and Brake fluid renewal. I also had the 16 spark plugs changed. I have only had this car just under 2 years, and was interested to know its over-all condition as a 20year old supercar. I was advised the engine mounts were at the end of their service life, and that doing the gearbox mounts too would be sensible. The driveshaft rubber linkage was also advised as it had some age related wear. This was expected on a car of this age. All the work was detailed fully in advance, there was no pressure to have it done, and a detailed cost break-down was given. The owner and I discussed the car at length, and it is obvious he is not only a very experienced Mercedes Engineer but also a proper car enthusiast.. my visits to DDR are always a pleasant experience. In 8 years I have never had any experience of them pushing for unnecessary work. I would always trust DDR, and recommend them to my friends. I will keep using them as long as I own a Mercedes.
Had my car serviced by DDR this week. Travelled a few miles as heard good things - rightly so. Fantastic service (literally) - extremely well priced for an S class and very efficient. Would definitely recommend and think they are more efficient and offer better customer service than many main dealers who charge a lot more!
Had a coolant leak on my cd 250 Mercedes. Rang up DDR and spoke to Dan. He came back within an hour with the problem, quoted a reasonable price, and fixed the leak. The customer service was very good and I would recommend them.
Another excellent service from DDR. I have used them many times for various items be it services or repairs.

Always very knowledgeable, fair with prices and honest about costs and recommendations.

Highly recommended!!
