Dealer-Standard Repairs
Why Choose Cedar Garage for Mercedes Repairs?
Mercedes-Benz cars are built for comfort and long-distance reliability, but even the best engineering has its known weak points. Our technicians repair Mercedes every day, from the A-Class, C-Class and E-Class to the S-Class, GLA, GLC and GLE, and they know the common Mercedes repairs well: leaking injector seals and intake pipes on CDI diesels, 7G-TRONIC and 9G-TRONIC gearbox faults, AIRMATIC air suspension, AdBlue faults, auxiliary batteries and heater blower regulators. Because we test rather than guess, you pay to fix the problem rather than for parts that were never needed.
Many Mercedes repairs need coding or an adaptation afterwards, from gearbox repairs to replacement control units. We carry this out in house with Mercedes-specific diagnostic equipment, so your car is repaired and ready to go in one visit without a trip to the dealer. We'll always explain what needs doing and what can wait, and never carry out extra work without your approval. Our Sompting workshop has on-site parking and is easy to reach from Worthing, Shoreham, Lancing and across West Sussex. If you can't get to us, ask about our collection and delivery service, and we can provide a hire car while your Mercedes is being repaired.

Frequently Asked Questions
Mercedes Repair FAQs
How much will my Mercedes repair cost?
It depends on what's wrong and the parts needed. We'll always give you a clear quote before any work starts, and we never carry out extra work without your approval.
Do you use genuine Mercedes parts, and will it affect my warranty?
We use quality parts made to the original standard, and can fit genuine Mercedes-Benz parts if you'd prefer. Having your Mercedes repaired by us won't affect its manufacturer's warranty.
Why can I hear a ticking or chuffing noise from my Mercedes diesel engine?
It could be a leak around the injectors, which is a common Mercedes diesel fault. It's worth fixing early before it gets worse, so book in and we'll take a look.
My Mercedes is showing an AdBlue warning. Can you fix it?
Yes. Book in as soon as the warning appears and we'll find the fault and fix it before your car stops restarting.
What does 'auxiliary battery malfunction' mean on my Mercedes?
Many Mercedes have a small second battery, and this warning usually means it's starting to fail. Book in and we'll test it, replace it if needed and clear the warning.
Can you repair my Mercedes automatic gearbox if it's in limp mode?
Yes. If your gearbox is stuck in one gear or showing a warning, book in and we'll find the cause and get it changing gear smoothly again.
Can you fix my Mercedes air suspension if it's sitting low?
Yes. If your Mercedes sits low or shows a suspension warning, book in for fault finding. We'll find the failed part and get it sitting at the right height again.
Are your Mercedes repairs guaranteed?
Yes. Our repairs come with a 12-month guarantee, so you can drive away with confidence.
