⚠️ Petrol, diesel, LPG or hybrid all suffer from carbon buildup. This returning customer with a meticulously maintained Jaguar XJ (2004 – 157,478 miles) booked in for diagnostics and Engine Carbon Clean. ⛑️ Health check identified little of note, but a slight oil weep from cam cover sensor. 📊 Diagnostics showed 9 active issues – 7 with the airflow sensors and 2 with a throttle valve sensor. Documented and cleared for the owner. Unfortunately the throttle valve sensor error remained so further investigation will be needed at a local garage. On with the clean and the tell-tale bass purr in the engine subsided, the engine now whisper quiet and the exhaust raspy and burbly again all ready to get back on the road. ☑️ Full Diagnostics ☑️ Engine Carbon Clean ☑️ Safety first, fully insured, IMI Certified and Which?
