2007 Jaguar XJ 2.7L Diesel · VF07 EXS

The 2007 Jaguar XJ presents a mixed mechanical picture. The most recent MOT, conducted on 11 December 2023 at 115,400 miles, passed, but only after a failure one week earlier on 4 December 2023 at 115,392 miles. That failure flagged excessively corroded offside front brake pipes under the floor and a supplementary restraint system warning lamp indicating an airbag or SRS fault. The rapid retest and pass suggest the brake pipe corrosion was addressed, yet the SRS lamp advisory from the failure was not carried forward as a defect in the pass record, meaning it may have been cleared without a confirmed permanent repair. The maintenance trend is therefore stable but fragile, with evidence of reactive rather than preventative work. The mileage progression tells a story of very light recent use. Between 5 January 2021 at 110,490 miles and 11 December 2023 at 115,400 miles, the car covered just 4,910 miles across nearly three years, averaging under 1,700 miles annually during that window. Earlier years were similarly gentle, with roughly 1,400 miles between January 2021 and January 2022, and about 2,000 miles between January 2022 and January 2023. This is well below the 6,074 miles per year implied by the overall 19-year average, indicating the car has spent extended periods stationary. Prolonged sitting accelerates brake pipe corrosion, perished rubber hoses, and dried-out suspension bushes, all of which appear in the record. Brake pipe corrosion is the dominant recurring theme. Advisories for corroded brake pipes contaminated with grease or other material appear in the January 2023 test at 113,381 miles, the January 2022 test at 111,801 miles, and the December 2023 failure at 115,392 miles. The offside front and offside areas are repeatedly affected, pointing to a systemic underfloor corrosion problem rather than an isolated incident. A buyer should have the entire underfloor brake line run inspected, paying close attention to the offside front-to-rear pipe and any sections routed along the subframe or inner wing. Surface corrosion covered in grease or underseal can mask severe wall thinning, and any pipe that has been flagged as excessively corroded once is likely to deteriorate again. Beyond the braking system, the December 2023 SRS warning lamp fault demands attention. Even if the lamp is currently off, the underlying cause, whether a failing seatbelt pretensioner, airbag sensor, or clock spring, may still be intermittent. The January 2023 test also flagged worn offside front tyre inner edge wear and cracking offside rear tyre sidewall, suggesting possible suspension misalignment or neglected tyre rotation. A thorough inspection of front suspension geometry, including wishbone bushes, track rod ends, and coil springs, is advisable. Given the car's low recent mileage and repeated corrosion advisories, a full underbody examination by a specialist familiar with XJ structural and brake system vulnerabilities is essential before purchase.
