Jaguar XJ Repair in South Salt Lake, UT
The Jaguar XJ is the flagship that defined what Jaguar means — a long-wheelbase luxury saloon that managed to be genuinely fast and beautifully built for over fifty years. At Scott's Auto & Clutch Repair in South Salt Lake, we work on XJ models from the X350 and X358 aluminium-bodied cars through the X351 generation — the final and arguably most dramatic expression of the XJ nameplate. These are serious cars that deserve careful, experienced attention.
Full-Service Jaguar XJ Repair — All Generations
We service modern Jaguar XJ models at our South Salt Lake shop — X350, X358, and X351 generations with AJ6, AJ-V8, and 5.0 supercharged engines. Every visit starts with a free diagnosis so you know exactly what your XJ needs before we touch it.

Why Jaguar XJ Drivers Choose Scott's Auto
The XJ is the most sophisticated Jaguar sedan — and the one where deferred maintenance causes the most expensive problems. Timing chain service on a neglected AJ-V8, air suspension compressor failure on an X351, or a cooling system that hasn't been touched in years — these are all serious repairs that compound quickly. We diagnose XJs thoroughly and give you a clear picture of what needs attention now and what can safely wait.
AJ-V8 Timing Chain Knowledge
X350 and X358 AJ-V8 timing chains are a known wear item at high mileage — stretch and tensioner wear lead to rattle and eventual timing failure. We inspect chain condition and replace the full assembly when wear exceeds spec.
Air Suspension Expertise on X351
The X351 XJ's air suspension is comfortable and sophisticated, but air compressors, bags, and sensors fail with age. We diagnose the full air suspension circuit and replace what's actually failed — not guess-replace the whole system.
Thorough Pre-Purchase Inspections
A used XJ at a private party price can be an exceptional value or a money pit depending on what's been deferred. We do thorough pre-purchase inspections on XJ models so you know what you're buying before you commit.
Free Diagnosis, Written Estimate
Road test, code scan, and full visual inspection before we recommend anything. You know what your XJ needs and what it costs before we start.
When to Bring Your Jaguar XJ In
The XJ rewards consistent maintenance and punishes neglect sharply. The issues below represent the most common repairs we perform on XJ models at our South Salt Lake shop. If your car is showing any of these symptoms, bring it in — the diagnosis is free and it's always cheaper to know what's wrong early.
Timing Chain Rattle on AJ-V8
The 4.2L and 4.0L AJ-V8 engines in X350 and X358 XJs develop timing chain wear in the 80,000–100,000-mile range when oil changes have been stretched. Cold-start rattle that quiets as oil pressure builds is the first sign. A worn chain can jump timing and cause catastrophic valve-to-piston contact. We inspect the chain, tensioners, and guides and replace the assembly before failure occurs.
Learn more →Air Suspension Failure on X351
X351 XJ air suspension compressors wear out, air bags leak, and height sensors fail — often independently, sometimes in cascades. You may notice the car sitting low in the rear, uneven ride height, or a constant compressor run sound. We diagnose each component of the air suspension system individually and replace what's actually failed.
Learn more →Brake Service — Flagship Weight and Performance
The XJ is a large, heavy vehicle that moves with startling speed — the brakes are working hard every time you use the performance the car offers. Front and rear brake wear is predictable and we inspect it at every service. Rear calipers on high-mileage XJs are prone to seizing — we service caliper slides and parking brake mechanisms at every brake job.
Learn more →Cooling System Failure — Water Pump and Thermostat
High-mileage XJ AJ-V8 water pumps fail internally — impeller separation is a documented failure mode that causes the pump to spin without moving coolant. You'll see a temperature rise with no obvious external leak. We replace the pump, thermostat, and inspect hoses and the coolant reservoir for secondary damage.
Learn more →Exhaust System Corrosion
XJ exhaust systems are exposed to the same Utah road salt environment as any vehicle, and the mid-section flex pipes and hangers corrode predictably. A growing exhaust drone or rattle at speed usually means a cracked flex section or broken hanger. We inspect and repair the exhaust run.

Scott's Auto & Clutch Repair has been independently owned and operating from the same South Salt Lake location since 1990. An XJ is a vehicle that deserves a mechanic who takes it seriously — not a quick oil change chain staffed with whoever showed up that day. The mechanic who diagnoses your XJ is the one who repairs it, start to finish, with direct accountability for the quality of the work.
We've worked on X350, X358, and X351 XJ models and know the platform's strengths and its maintenance demands. Whether your XJ needs a timing chain, an air suspension diagnosis, a brake refresh, or a thorough pre-purchase inspection, we'll give you a written estimate and an honest timeline before any work begins.
How We Work With Jaguar XJ Drivers
Tell Us What Your XJ Is Doing
Describe the symptom — noise, warning light, handling change, or ride quality concern. The detail you provide helps us focus the diagnostic accurately.
Free Diagnostic Inspection
Road test, code scan, fluid inspection, and targeted examination of what the symptom indicates — before we recommend any work.
Written Estimate in Plain English
What needs to be done, what it costs, and why — in language you can understand. Nothing starts until you approve it.
Only What Your XJ Actually Needs
An XJ can generate a long service estimate on deferred maintenance — we prioritize what's urgent, tell you what can safely wait, and don't manufacture urgency.

We road test after every repair. At pickup we walk you through what was done and what to monitor going forward.

Utah's temperature swings, mountain roads, and high altitude put unique demands on your vehicle. Here's what we've learned from years of servicing Jaguar XJs in the Salt Lake Valley.
AJ-V8 oil change discipline: the timing chain tensioner on X350 and X358 XJs is oil-pressure dependent. If you let oil changes slide past 5,000–6,000 miles on a high-mileage AJ-V8, you're accelerating chain and tensioner wear. Use full-synthetic 5W-30 and change it on schedule — the chain replacement cost if you skip this is many times the oil change cost.
X351 air suspension: if you hear the compressor running frequently or the car sits low overnight, address it promptly. A failed air bag puts all the load on the compressor, which burns it out quickly. Replacing just a bag is far cheaper than replacing a bag plus a burned compressor.
Pre-purchase inspection for used XJ: if you're shopping for a used X350, X358, or X351 XJ, a pre-purchase inspection is essential. Deferred timing chain service, failing air suspension, and cooling system neglect are all invisible on a test drive but extremely expensive to repair. We do thorough pre-purchase inspections and give you an honest report — worth every penny before you write a check.

5-Star Reviews
What Our Customers Say
Real reviews from Google — 5 stars across the board
“Took my grandson's car in to have the clutch looked at. We thought it might need a new clutch. Scott explained the level of wear and thought it was premature to replace it. He could have just said it needed a new clutch and I wouldn't have blinked an eye. I appreciated the honesty. Only needed a clutch adjustment. I also had him wire up a new set of fog lights and they look and work great. He will definitely get our business in the future.”
“Scott is a skilled mechanic who provides great service at a fair price. This is my go to place for car repairs.”
“I highly recommend this auto and repair shop! I have been to them twice now and both times they have been fair and honest with me. They are friendly, trustworthy, competent and seem eager to help and problem solve car issues!”
