This article summarizes a maintenance log for a 2007 BMW 335i. It is intended as a useful reference for people researching the car and for anyone keeping records on an older turbocharged vehicle. The registration, owner details, supplier locations and dollar amounts have been left out.
The record starts at about 162,000 km in March 2019 and reaches 246,102 km in July 2026. It includes routine oil services as well as work on the cooling system, turbo wastegate, suspension, engine mounts, sensors, belts, brakes and tyres. This is a transcription and summary of the supplied log, not an independent inspection or a substitute for invoices.
Maintenance timeline
2019: routine servicing and early repairs
At roughly 162,000–168,000 km, the log records oil services, a thermostat-to-cylinder-head hose and coolant, shock absorbers, a wastegate solenoid and rear tyres. The entries show regular attention to basic servicing alongside age-related cooling and suspension work.
2020–2021: turbo, cooling and engine support
Between about 170,000 and 186,500 km, the record includes further oil changes, a turbo wastegate repair, a replacement oil cooler line and radiator top hose, front lower angle rods, engine mounts and an oil pan gasket with bolts. A turbo installation kit is also listed. The wastegate repair note mentions a header gasket and oil-feed O-rings.
2022–2023: servicing and engine sensors
Oil changes are recorded from approximately 190,000 to 200,340 km, along with rear tyres. At 205,060 km, the log lists a crankshaft position sensor and camshaft position sensors. The camshaft sensor appears twice in the source record, so that entry may be a duplicate rather than two separate replacements.
2024: cooling-system and front-end work
At about 211,514 km, an oil and filter service is recorded. The log then lists a Mahle radiator, an intercooler shroud clip, a coolant expansion tank, another crankshaft position sensor and a camshaft position sensor. At around 215,000–218,000 km it also lists belt pulleys, a mechanical belt tensioner and drive belt, front and rear brake pads, engine mounts, front tyres, a water pump, thermostat and several coolant hoses. An automatic transmission fluid flush is mentioned, but the date and fluid specification are not recorded.
Part references transcribed from the log include crankshaft position sensor 13627525015, coolant expansion tank 17137607482, water pump 11519455978, thermostat 11537549476, water-pump-to-thermostat hose 11537545665, coolant inlet hose 11537558523 and intercooler shroud clip 7545367. Confirm fitment against the vehicle before ordering; part references in a personal log are not a fitment guarantee.
2025–2026: continued oil and tyre records
An oil change is recorded at 227,350 km in December 2025, followed by oil services at 238,410 km in February 2026 and 246,102 km in July 2026. The latest oil entry specifies 5W-40 Nulon. A Winrun R330 tyre entry gives size 255/40R17.
A coolant hose from the thermostat to the engine block is also listed at 246,102 km, but its source date is written as 29 July 2025. Because the same mileage appears in a July 2026 oil entry, the hose date should be checked against the original invoice or notes.
What the records say about the car
The history suggests that maintenance was tracked over several years and that work extended beyond routine oil changes. The repeated focus on cooling hoses, radiator components, sensors, belts and mounts is useful context when inspecting an older 335i. It does not establish the present condition of those parts, and a replacement entry should be verified with receipts where possible.
A previous Marketplace description also reported upgraded wastegates, new turbo cores and a mild Stage 1 tune, with power estimated at about 350 wheel horsepower. Those are seller-reported claims from an older advertisement; the supplied maintenance log contains no dyno sheet or supporting invoices, so they should be independently verified before being treated as current specifications.
Read the log with the right context
For a line-by-line reference, download the anonymized BMW 335i maintenance record (PDF). It includes the recorded dates, odometer readings, parts and notes, with incomplete or conflicting entries called out.
- Some entries have no date or odometer reading, so their position in the timeline is approximate.
- The shock absorbers and wastegate solenoid are recorded at 168,000 km with dates in January 2019. That mileage conflicts with later entries showing 162,000 km in March and 167,000 km in October 2019; verify the dates/year against original records.
- The duplicate camshaft sensor entry and the coolant-hose date need checking against original records.
- A past Marketplace listing stated 250,000 km, while the supplied log records 246,102 km in July 2026. Confirm the current odometer and reconcile the dates before using either figure in a new sale advertisement.
- The log records work performed as entered by the owner; it does not independently prove the work, parts quality, current operation or roadworthiness.
For a prospective buyer, the best next step is to compare this summary with dated invoices, inspect the vehicle in person and arrange an independent pre-purchase inspection. For the next owner, keeping each receipt with its date, odometer reading, part number and workshop details will make the service history easier to verify and maintain.
