Mercedes-Benz Service History

Timing chain

No scheduled replacement

CHAIN, not a belt. AUTODOC catalogues a timing chain kit against M 282.914 and no belt kit. This is the useful counter-intuitive result: the M282 is a Renault-Nissan-Daimler design (the HR13DDT family), and the OTHER Renault-derived Mercedes in this file - the OM607 diesel - does run a rubber belt. Shared parentage predicts nothing about the drive; the catalogue does. No replacement interval is published.

Timing chain

No scheduled replacement

CHAIN, both tests applied and agreeing. Camshaft test: febi's own catalogue titles part 172275 'Timing Chain for camshaft' (silent chain, 140 links; D-S30), and AUTODOC fits that part to the M 264.915 (D-S29). Opposite-kit test: AUTODOC lists 13 timing chain kits for the C 200 EQ Boost (205.077) and its belt category says 'Unfortunately, item Timing belt for ... C 200 EQ Boost (205.077) 135 KW is not available', giving the displacement as '1497 CCM Petrol/Electric' (D-S29). No replacement interval published. Interference not stated. mildHybrid, not hybrid: the 1.5 C 200 carries a '48 volt system with belt-driven starter/alternator' adding 10 kW (D-S31), and DVLA has filed these cars both as PETROL and as HYBRID ELECTRIC.

Timing chain

No scheduled replacement

CHAIN, both tests applied and agreeing. NOT in the task list - added because DVLA files a 2021 C-Class 1.5 as HYBRID ELECTRIC, and from mid-2021 the new W206 C-Class uses this different engine at 1,496 cc, one cc off the M264's 1,497. Camshaft test: febi's own catalogue titles part 192664 'Timing Chain for camshaft' (silent chain, 128 links; D-S33), and AUTODOC fits it to the M 254.915 (D-S32). Opposite-kit test: AUTODOC lists febi 192664, SWAG 33 11 0924 and PartsTec PTA114-0562 chain kits and its belt category says 'Unfortunately, item Timing belt for ... C 180 (206.041) 125 KW is not available', displacement '1496 CCM Petrol/Electric' (D-S32). No interval. Interference not stated. mildHybrid is set because AUTODOC classifies the car as Petrol/Electric; no fetched source confirms the 48V ISG, so treat the hybrid classification itself as reported. Only the C 180 was verified; the W206 C 200 and other M254 1.5 fitments were not checked.

Timing chain

No scheduled replacement

Chain. AUTODOC catalogues a timing chain kit against M 270.910 (transverse, A/B/CLA/GLA - S10) and a timing chain against M 274.910 (longitudinal, C-Class - S9). No replacement interval is published by Mercedes.

Timing chain

No scheduled replacement

CHAIN, both tests applied and agreeing. Camshaft test: Laser Tools 6896 'enables the engine to be locked in its timed position for the removal and refitting of the camshaft drive chain' on Mercedes 1.8, 2.1 and 2.2 diesels, and lists engine code 651.901 - the 1.8 (D-S28). Opposite-kit test: AUTODOC lists 182 timing chain kits for the B 180 CDI 1.8 (OM 651.901, 1796 CCM) and its belt category says 'Unfortunately, item Timing belt ... B 180 CDI (246.200) 80 KW is not available' (D-S27). No replacement interval published. Interference not stated. Added as its own entry rather than widening the existing '2.1 CDI / d (OM651)' cc to [1796, 2143]: the label would then call a 1.8 a 2.1, and a contiguous range could sweep in other, unresearched Mercedes diesels whose DVLA capacity falls between the two. Only the W246 fitments were verified; other 1.8 OM651 fitments (e.g. W176 A 180 CDI, W204/W212 180/200 CDI) were not checked, so years/models may be incomplete.

Timing chain

No scheduled replacement

CHAIN, both tests applied and agreeing. Camshaft test: the M271 1.8 'Chain Driven Camshaft Alignment Timing Locking Kit' locks the camshafts and holds 'chain securely on sprocket while winding in a new chain', covering M271 E18ML, DE18ML and DE18LA across W203/W204/W211/W212/C209/R171 (D-S25). Opposite-kit test: AUTODOC lists 171 timing chain kits for the W204 C 180 Kompressor, M 271.952; its belt category's only item is a 7-RIB belt 'with water pump' (an auxiliary ribbed belt misfiled) and no toothed timing belt is listed (D-S26). No replacement interval published. Interference not stated. AUTODOC also lists a '1.6 Kompressor' W204 C 180 (M271 E16ML, 2008-2014); that smaller engine is not covered by this entry (its DVLA capacity was not checked).

Timing chain

No scheduled replacement

AUTODOC catalogues timing CHAIN parts (iwis, Febi, BGA, Hepu, SWAG, Magneti Marelli) against OM 654.920 and lists no belt. Mercedes publishes no replacement interval. AUTODOC prints its own editorial line on that page suggesting every 150,000 km, but that is a retailer recommendation and not a manufacturer figure, so it is deliberately NOT recorded here.

Timing chain

No scheduled replacement

Chain. AUTODOC catalogues timing chain parts against M 264.920 and no belt. No replacement interval is published by Mercedes.

Timing chain

No scheduled replacement

Chain. AUTODOC catalogues a timing chain kit against M 274.920 (S8). No replacement interval is published by Mercedes.

Timing chain

No scheduled replacement

Timing chain, driven from the rear of the block. Mercedes publishes NO replacement interval: the chain does not appear as a maintenance item anywhere in the MY13 or MY17 booklets, so in the schedule it is a lifetime part. revised is flagged because the catalogue kits for this engine are sold as upgraded/revised parts (S5) - the OM651 is the Mercedes engine with a genuine chain-stretch reputation - but no manufacturer document confirming a revision was found, so treat that flag as reported. Interference status was not sourced and is deliberately left null.

Timing chain

No scheduled replacement

Chain, both tests passed. OPPOSITE-KIT: Navara D23 2.3 dCi (YS23DDT) — 36 chain-kit articles, no banner (A2-S7); timing belt 'not available' (A2-S8). Mercedes X 250 d (OM 699.303) — chain kits listed, belt 'not available' (A2-S10, A2-S11). CAMSHAFT: the Navara kits contain a camshaft gear (febi 37999 'Gear, camshaft'; Gates CHK1025 'Gear/Sprocket, camshaft', A2-S7) and the X-Class kits state 'Driven Units: Camshaft' (A2-S10). The arrangement is the Renault 2.3 dCi's: 'a chain drive between the crankshaft and exhaust camshaft - the inlet camshaft is gear driven from the exhaust camshaft' (Laser Tools, A2-S12) — a gear, not a second chain or belt, so no `secondary` drive is recorded. SAME ENGINE ACROSS BADGES: Lymm sells one kit for YS23DDT, YS23DDTT and the Renault M9T codes at '2298cc / 2299cc', fitting Navara 2015-2025 and NV400 (A2-S9); the X-Class kits carry the same 116-link chain as the Navara kits (A2-S10, A2-S7); Parkers states Nissan, Mercedes and Renault share the two 2.3 dCi engines (A2-S13). No replacement interval was found in any fetched source (catalogue '150,000 km' figures seen in search snippets are expected-life marketing and were not fetched or used).

Timing chain

No scheduled replacement

CHAIN, both tests applied and agreeing. Camshaft test: febi's own catalogue titles kit 172882 'Timing Chain Kit for camshaft' (chain, hydraulic tensioner, three guide rails; OE 654 050 03 00; D-S35), and AUTODOC fits that kit to the OM 656.929 (D-S34). Opposite-kit test: AUTODOC's belt category for the E 400 d says 'Unfortunately, item Timing belt for ... E 400 d (213.020) 250 KW is not available', displacement '2925 CCM' (D-S34). CAUTION on method: AUTODOC's chain-kit list for this car also contains febi 171579, which febi itself calls a 'Chain for oil pump' - so a chain-kit listing alone is not the camshaft test. No replacement interval published. Interference not stated.

Timing chain

No scheduled replacement

Chain. AUTODOC catalogues a timing chain kit against M 256.930 - the Febi part is described as a Silent Chain - and lists no belt. No replacement interval is published by Mercedes.

Timing chain

No scheduled replacement

Chain. AUTODOC catalogues a timing chain guide against M 276.820. No replacement interval is published by Mercedes.

Timing chain

No scheduled replacement

Febi chain kit 30321 - a double-row timing chain, tensioner and six guide rails - is catalogued specifically against MERCEDES OM642.8../642.9.. various 3L diesel models. No replacement interval appears in any Mercedes maintenance booklet. Note that on this engine the chain runs at the BACK of the V, which is why the job is engine-out on most applications even though it is never scheduled.

Timing chain

No scheduled replacement

Chain. AUTODOC catalogues timing chain parts against M 276.952. No replacement interval is published by Mercedes.

Timing chain

No scheduled replacement

Chain. AUTODOC catalogues a timing chain kit against M 177.980 (Febi 184580, 98 and 88 links). No replacement interval is published by Mercedes.

Timing chain

No scheduled replacement

CHAIN (duplex), both tests applied and agreeing. Camshaft test: febi's own catalogue titles part 25207 'Timing Chain for camshaft', a 168-link DUPLEX chain (OE 003 997 68 94; D-S37), and AUTODOC fits it to the M 113.963 SL 500 (D-S36). Opposite-kit test: AUTODOC lists 52 timing chain kits for the SL 500 M 113.963; its belt category shows no toothed belt at all - only 6-rib EPDM auxiliary belts 2386-2405 mm long, misfiled (D-S36). No replacement interval published. Interference not stated. AUTODOC lists the 388 hp SL 500 of 2006 on as a separate variant; its engine was not checked, and this entry only reaches it if DVLA reports 4,966 cc.
