Our Services

At JD Diagnostics (Diesel Doctor), our mechanics use the best equipment on the market, on each and every vehicle we perform a diagnostic to ensure the most accurate code readings.
In most cases, we try to direct people towards engine rebuilds rather than replacements. They’re more cost-effective and are actually better in most cases. We use OEM parts and diagnose the actual source of the problem so that you don’t replace your entire engine with a new (often subpar model) and find that you’re still having the same issues. When we rebuild, everything is done locally and in-house so that your engine rebuild is done specifically for your truck. Overall JD Diagnostics ( is a complete diesel engine service centre solution. In the event that a rebuild isn’t recommended, we’re also equipped to replace.
We specialize in diesel truck transmission diagnostic and repair because we know how important it is to properly maintain equipment. A small amount of work now can pay off huge in the future. For example, winter conditions can wreak havoc on transmissions. We can make sure you’ve got the best transmission fluid for your make and model. Call us if you need help figuring out the best options.
Custom suspension installs and suspension repair is one of our specialties. We use BDS lift kits as our preferred partner. Our highly skilled technical staff can help you with all of your suspension needs. Installs typically range from $1,500 to $5,000+ (parts and labour) depending on a variety of factors like make, model, kit type, and labour.
Did you know that without regular maintenance an air conditioner loses a percentage of its original efficiency every year? This means that without proper maintenance, your air conditioning isn’t pumping at full capacity. When it comes to comfort in the summer months, strong A/C is a must. Recharge and minor repairs typically cost between $200 and $400. Extensive air conditioning repairs can cost $1,000-$4,000 or more, depending on make and model.

We partner with 3K Calibrations to tune our customer’s trucks.

We supply a large selection of tires and rims of all shapes and sizes including balancing and installations. Our tire services are available in Chilliwack, Abbotsford and the rest of the Fraser Valley.

A properly maintained fuel system is essential to top performance. If you’re tired of spending your time at the pump, we can upgrade your tank size too. Our qualified team of technicians can diagnose and maintain your fuel systems and keep them running in top shape. General fuel system maintenance starts at $750 and increases based on a variety of factors. Call our shop and we’ll be happy to chat about the details.

Engine coolant maintenance is just as important as an oil change. In fact, the coolant condition in a diesel engine may even be more important than in a gasoline engine.

Keeping your fluids maintained is essential to the proper function and longevity of your vehicle. Our team of technicians can get your oil and fluids changed in a jiffy.

"Recently had my EcoDiesel EGR and cat delete done at JD Diagnostics & Diesel Repair in Abbotsford.
Had some issues after the fact and those were rectified quickly and professionally.
I would recommend their services to anyone looking for a no-nonsense qualified diesel shop."

"Never have I had such an easy time at a shop. Truck serviced, my ECM tuned, and now I have more power with a way more efficient engine. AND my friends can't believe either how cheap it was for everything to get completed or how quick. Amazed at how smooth this operation is. HIGHLY RECOMMEND!"

"These guys are super!! They are both professional and welcoming and most certainly took care of our diesel and had her repaired in reasonable time. If I could refer a place to work on your vehicle, it would be JD Diagnostics & Diesel Repair."

What is the Cost of Owning a Diesel Truck in Canada?

The first generation of diesel trucks in Canada was slow, smelly, and their vibrating engines made them unpleasant to drive. And though diesel has undergone a lot of changes over the past few decades, the perception that diesel trucks are agricultural still holds strong in a lot of people's minds. However, education is key, and at JD Diagnostics we have made it our mission to enlighten on the cost and benefits of diesel trucks.
