Jaguar Repair in Dallas — SDD Diagnostics, Air Suspension & Supercharger Specialists
From air suspension and supercharged V8 engines to timing chains and electrical systems, we repair Jaguar vehicles with factory SDD diagnostics and British luxury automotive expertise.
Why Choose Us for Jaguar Service
SDD Diagnostics (Factory System)
We use genuine Jaguar SDD (Symptom Driven Diagnostics) software - the exact same system Jaguar dealers use. This is essential for reading all control modules, performing programming, calibrations, and guided diagnostics on modern Jaguars.
Air Suspension Specialists
Jaguar XJ and XF air suspension systems are complex. We have the specialized tools and SDD software to diagnose compressor failures, air strut leaks, valve block issues, and perform proper system calibration after repairs.
Supercharged V8 Experts
The supercharged AJ-V8 engine is powerful but requires specific expertise. We handle supercharger rebuilds, timing chains, water pump packages, and all the common AJ133 and AJ-V8 engine issues with precision.

Common Jaguar Problems We Fix
Jaguar vehicles deliver stunning performance and luxury, but they have specific mechanical and electrical issues that require specialized diagnostic equipment, Jaguar expertise, and proper repair procedures.
Air Suspension Failure
Symptoms
- • Vehicle sagging
- • Suspension fault warning
- • Compressor running constantly
- • Rough ride
- • Uneven height
Root Cause
Air struts leak, compressor fails, air lines crack, valve block malfunctions on XJ and XF models
Our Solution
SDD diagnostics to pinpoint fault, replace failed air struts or compressor, calibrate system with factory software
Supercharger Failure (AJ-V8)
Symptoms
- • Whining/grinding noise
- • Loss of power
- • Check engine light
- • Supercharger fault code
- • Belt squeal
Root Cause
Supercharger bearings fail, coupler wears out, oil leaks from snout seal, belt tensioner fails
Our Solution
Rebuild or replace supercharger, change supercharger oil, replace coupler and belt, update software
Timing Chain Tensioner Failure
Symptoms
- • Rattling on startup
- • Check engine light
- • Rough running
- • Timing codes
- • Metal in oil
Root Cause
V8 engines (especially 5.0L AJ133) have timing chain tensioners that fail 80k-120k miles
Our Solution
Replace all timing chains, tensioners, guides - major engine job requiring removal of front accessories
Electrical Module Failures
Symptoms
- • Multiple warning lights
- • Features not working
- • Battery drain
- • No start
- • Random faults
Root Cause
Jaguars have complex electrical systems with multiple modules that fail - PDC, ACM, BCM, TCM
Our Solution
SDD diagnostics to identify failed module, replace or reprogram module, verify communication network
Water Pump & Thermostat Leaks
Symptoms
- • Coolant leak
- • Overheating
- • Low coolant warning
- • Steam from engine
- • Sweet smell
Root Cause
Plastic water pump housing and thermostat housing crack from heat cycles, common 60k-100k failure

Jaguar Models We Service in Dallas
From classic XJ6 sedans to modern F-Type sports cars, supercharged XJR performance models to I-Pace electric vehicles, we service all Jaguar models from 1995 to present with specialized British luxury car expertise.
Supercharged V8 Engine Expertise
Jaguar's supercharged AJ-V8 engines deliver incredible performance - from 470hp in the XJR to 550hp in the F-Type R. But they require specific maintenance and expertise.
Supercharger service is critical. The Eaton supercharger needs oil changes every 100k miles. The coupler (connecting supercharger to crankshaft) wears out and causes whining noises. Ignoring these issues leads to supercharger failure costing $4,000+.
Timing chains are another concern. The 5.0L AJ133 engine has timing chain tensioners that fail. We replace chains, tensioners, and guides before they cause engine damage. This is a major service requiring 12-16 hours of labor.
Water pump packages are essential preventive maintenance. We replace the water pump, thermostat, and coolant crossover pipes together. These plastic components fail 60k-100k miles causing overheating and engine damage.
Our SDD diagnostics identify supercharger faults, timing issues, and cooling system problems before they become catastrophic failures. We keep your supercharged Jaguar performing at its best.
